  • Android Multiple objects in SimpleAdapter

    - by Adam Sherratt
    I have a need (unless you can think of a better way) of passing multiple objects to a custom list adapter. I know that I'm barking up the wrong tree here, and would appreciate someone setting me on the right course! Thanks playlistadapter = new MyPlaylistAdapter(MyApplication.getAppContext(), songsList, retained_songsList, folderMode, R.layout.file_view, new String[] { "songTitle","songAlbum", "songPath" }, new int[] { R.id.checkTextView, R.id.text2, R.id.text3 }); And my adapter class: public class MyPlaylistAdapter extends SimpleAdapter{ private ArrayList <Song> songsList = new ArrayList<Song>(); private ArrayList <Song> retained_songsList = new ArrayList<Song>(); private ArrayList<Song> playlistcheck = new ArrayList<Song>(); private String folderMode; private String TAG = "AndroidMediaCenter"; public MyPlaylistAdapter(Context context,List<Song> SongsList, List<Song> Retained_songsList, String FolderMode,int resource, String[] from, int[] to) { super(context, null, resource, from, to); songsList.clear(); songsList.addAll(SongsList); Log.i(TAG, "MyPlayListAdapter Songslist = " + songsList.size()); retained_songsList.clear(); retained_songsList.addAll(Retained_songsList); folderMode = FolderMode; } public View getView(int position, View convertView, ViewGroup parent) { //PlayListViewHolder holder; CheckedTextView checkTextView; TextView text2; TextView text3; if (convertView == null) { LayoutInflater inflater = (LayoutInflater) MyApplication.getAppContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); //LayoutInflater inflater=getLayoutInflater(); convertView=inflater.inflate(R.layout.file_view, parent, false); //convertView.setBackgroundColor(0xFF00FF00 ); //holder = new PlayListViewHolder(); checkTextView = (CheckedTextView) convertView.findViewById(R.id.checkTextView); text2 = (TextView) convertView.findViewById(R.id.text2); text3 = (TextView) convertView.findViewById(R.id.text3); //convertView.setTag(holder); } else { //holder = (PlayListViewHolder) convertView.getTag(); } //put something into textviews String tracks = null; String tracks_Details = null; String trackspath = null; tracks = songsList.get(position).getSongTitle(); tracks_Details = songsList.get(position).getAlbum() + " (" + songsList.get(position).getArtist() + ")"; trackspath = songsList.get(position).getSongPath(); checkTextView = (CheckedTextView) convertView.findViewById(R.id.checkTextView); text2 = (TextView) convertView.findViewById(R.id.text2); text3 = (TextView) convertView.findViewById(R.id.text3); checkTextView.setText(tracks); if(folderMode.equals("Playlists")){ checkTextView.setBackgroundColor(Color.GREEN); checkTextView.setChecked(false); try { int listsize_rs = retained_songsList.size(); for (int j = 0; j<listsize_rs;j++){ if((retained_songsList.get(j).getSongPath()).equals(songsList.get(position).getSongPath())){ checkTextView.setBackgroundColor(Color.TRANSPARENT); //Need to check here whether the checkedtextview is ticked or not checkTextView.setChecked(true); playlistcheck.add(songsList.get(position)); break; } } } catch (Exception e) { e.printStackTrace(); } }else { //Need to check here whether the checkedtextview is ticked or not try { if (songsList.get(position).getSongCheckedStatus()==true){ checkTextView.setChecked(true); }else{ checkTextView.setChecked(false); } } catch (Exception e) { e.printStackTrace(); } } text2.setText(tracks_Details); text3.setText(trackspath); Log.i(TAG, "MyPlayListAdapter Songslist = " + songsList.size()); return convertView; } } However, this doesn't inflate, throwing the following errors: 10-26 23:11:09.464: E/AndroidRuntime(2826): FATAL EXCEPTION: main 10-26 23:11:09.464: E/AndroidRuntime(2826): java.lang.RuntimeException: Error receiving broadcast Intent { act=android.intent.action.GetMusicComplete flg=0x10 } in com.Nmidia.AMC.MusicActivity$18@414c5770 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.app.LoadedApk$ReceiverDispatcher$Args.run(LoadedApk.java:765) 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.os.Handler.handleCallback(Handler.java:615) 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.os.Handler.dispatchMessage(Handler.java:92) 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.os.Looper.loop(Looper.java:137) 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.app.ActivityThread.main(ActivityThread.java:4745) 10-26 23:11:09.464: E/AndroidRuntime(2826): at java.lang.reflect.Method.invokeNative(Native Method) 10-26 23:11:09.464: E/AndroidRuntime(2826): at java.lang.reflect.Method.invoke(Method.java:511) 10-26 23:11:09.464: E/AndroidRuntime(2826): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 10-26 23:11:09.464: E/AndroidRuntime(2826): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 10-26 23:11:09.464: E/AndroidRuntime(2826): at dalvik.system.NativeStart.main(Native Method) 10-26 23:11:09.464: E/AndroidRuntime(2826): Caused by: java.lang.NullPointerException 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.widget.SimpleAdapter.getCount(SimpleAdapter.java:93) 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.widget.ListView.setAdapter(ListView.java:460) 10-26 23:11:09.464: E/AndroidRuntime(2826): at com.Nmidia.AMC.MusicActivity.setFilterMusic(MusicActivity.java:1230) 10-26 23:11:09.464: E/AndroidRuntime(2826): at com.Nmidia.AMC.MusicActivity$18.onReceive(MusicActivity.java:996) 10-26 23:11:09.464: E/AndroidRuntime(2826): at android.app.LoadedApk$ReceiverDispatcher$Args.run(LoadedApk.java:755) 10-26 23:11:09.464: E/AndroidRuntime(2826): ... 9 more

  • JScrollPane content to image

    - by Sebastian Ikaros Rizzo
    I'm trying to save the main viewport and headers of a JScrollPane (larger than screen) to PNG image files. I created 3 classes extending JPanel (MainTablePanel, MapsHeaderPanel and ItemsHeaderPanel) and set them to the viewports. Each of them has this method: public BufferedImage createImage() { BufferedImage bi = new BufferedImage(getSize().width, getSize().height, BufferedImage.TYPE_INT_ARGB); Graphics g = bi.createGraphics(); paint(g); g.dispose(); return bi; } Each class has also a paint method, which paints the background and then call the super.paint() to paint some label. For example: public void paint(Graphics g){ g.setColor(Color.BLACK); g.fillRect(0, 0, getWidth(), getHeight()); g.setColor(new Color(255, 255, 0, 50)); // for loop that paints some vertical yellow lines for(int i=0; i<getWidth(); i+=K.mW){ g.fillRect(i-1, 0, 2, getHeight()); if(i%(K.mW*5)==0){ g.fillRect(i-2, 0, 4, getHeight()); } } // called to pain some rotated JLabels super.paint(g); } From an external JFrame I then tried to save them to PNG file, using this code: BufferedImage tableImg = mainTableP.createImage(); BufferedImage topImg = mapsHeaderP.createImage(); BufferedImage leftImg = itemsHeaderP.createImage(); ImageIO.write(tableImg, "png", new File(s.homeDir+"/table.png")); ImageIO.write(topImg, "png", new File(s.homeDir+"/top.png")); ImageIO.write(leftImg, "png", new File(s.homeDir+"/left.png")); This is a screenshot of the application running: screenshot And this is the header exported: top If I comment the "super.paint(g)" instruction, I obtain a correct image (thus without all JLables, clearly). It seems like the second paint (super.paint(g)) is painted shifted into the BufferedImage and taking elements outside its JPanel. Somebody could explain me this behaviour? Thank you. ========== EDIT for SSCCE ==================================== This should compile. You can execute it as it is, and in c:\ you'll find two images (top.png and left.png) that should be the same as the two headers. Unfortunately, they are not. Background is not painted. Moreover (especially if you look at left.png) you can see that the labels are painted twice and shifted (note, for example, "Left test 21"). import java.awt.*; import java.awt.image.BufferedImage; import java.io.File; import javax.imageio.ImageIO; import javax.swing.*; public class Main { public static void main(String[] args) { JFrame frame = new JFrame(); frame.setLayout(null); frame.setSize(800, 600); JScrollPane scrollP = new JScrollPane(); scrollP.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS); scrollP.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS); MyPanel top = new MyPanel(); for(int i=0; i<30; i++){ JLabel label = new JLabel("Test "+i); label.setOpaque(false); label.setBounds(50*i, 40, 50, 20); label.setForeground(Color.GREEN); top.add(label); } top.setLayout(null); top.setOpaque(false); top.setPreferredSize(new Dimension(50*30, 200)); top.validate(); MyPanel left = new MyPanel(); for(int i=0; i<30; i++){ JLabel label = new JLabel("Left test "+i); label.setBounds(0, 50*i, 100, 20); label.setForeground(Color.RED); left.add(label); } left.setLayout(null); left.setOpaque(false); left.setPreferredSize(new Dimension(200, 50*30)); MyPanel center = new MyPanel(); center.setLayout(null); center.setOpaque(false); center.setPreferredSize(new Dimension(50*30, 50*30)); scrollP.setViewportView(center); scrollP.setColumnHeaderView(top); scrollP.setRowHeaderView(left); scrollP.setBounds(0, 50, 750, 500); frame.add(scrollP); frame.setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); frame.setVisible(true); try{ BufferedImage topImg = top.createImage(); ImageIO.write(topImg, "png", new File("C:/top.png")); BufferedImage leftImg = left.createImage(); ImageIO.write(leftImg, "png", new File("C:/left.png")); }catch(Exception e){ e.printStackTrace(); } } } class MyPanel extends JPanel{ public void paint(Graphics g){ g.setColor(Color.BLACK); g.fillRect(0, 0, getWidth(), getHeight()); g.setColor(new Color(255, 255, 0, 50)); for(int i=0; i<getWidth(); i+=50){ g.fillRect(i-1, 0, 2, getHeight()); } super.paint(g); // COMMENT this line to obtain background images } public BufferedImage createImage() { BufferedImage bi = new BufferedImage(getSize().width, getSize().height, BufferedImage.TYPE_INT_ARGB); Graphics g = bi.createGraphics(); paint(g); g.dispose(); return bi; } }

  • How do I get a JComponent to resize after calling `setVisible(true)`?

    - by iWerner
    Our application displays a 2D view of our data (mainly maps) and then allows the user to change to a 3D view. The 2D and 3D views are generated by custom C++ code that is SWIG'ed into our Swing GUI and wrapped within a JComponent. These JComponents are then displayed within another parent JComponent. Our problem is that when we change from the 2D to the 3D view and then back to the 2D view, when we resize the window the 2D view does not get resized. The resize events don't get sent to the 2D view. Our application runs under Linux (Fedora 11). We're running Java version 1.6.0_12. Here is some sample code in which I've replaced the 2D view and 3D view with two 2 JButtons, that produces the same behaviour. Once you go to 3D and then back to 2D, resizing the window does not cause the 2D view to be resized. /* TestFrame.java * Compile with: $ javac TestFrame.java * Run with: $ java TestFrame */ import java.awt.BorderLayout; import java.awt.Container; import java.awt.event.ComponentEvent; import java.awt.event.ComponentListener; import javax.swing.JButton; public class TestFrame extends javax.swing.JFrame { private boolean mode2D = true; private JButton view2D = null; private JButton view3D = null; private Container parent = null; public TestFrame() { initComponents(); containerPanel.setLayout(new BorderLayout()); view2D = new JButton("2D View"); view2D.addComponentListener(new MyListener("2D VIEW")); containerPanel.add(view2D); } private void changerButtonActionPerformed(java.awt.event.ActionEvent evt) { if (parent == null) { parent = view2D.getParent(); } if (mode2D) { System.out.println("Going from 2D to 3D"); view2D.setVisible(false); if (view3D != null) { view3D.setVisible(true); } else { view3D = new JButton("3D View"); view3D.addComponentListener(new MyListener("3D VIEW")); parent.add(view3D); } ((JButton) evt.getSource()).setText("Change to 2D"); mode2D = false; } else { System.out.println("Going from 3D to 2D"); view3D.setVisible(false); view2D.setVisible(true); ((JButton) evt.getSource()).setText("Change to 3D"); mode2D = true; } } public static void main(String args[]) { java.awt.EventQueue.invokeLater(new Runnable() { public void run() { new TestFrame().setVisible(true); } }); } private javax.swing.JPanel containerPanel; private javax.swing.JButton changerButton; private class MyListener implements ComponentListener { private String name; public MyListener(String name) { this.name = name; } @Override public void componentHidden(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Hidden"); } @Override public void componentResized(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Resized"); } @Override public void componentShown(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Shown"); } @Override public void componentMoved(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Moved"); } }; @SuppressWarnings("unchecked") private void initComponents() { containerPanel = new javax.swing.JPanel(); changerButton = new javax.swing.JButton(); setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); containerPanel.setBorder(new javax.swing.border.MatteBorder(null)); javax.swing.GroupLayout containerPanelLayout = new javax.swing.GroupLayout(containerPanel); containerPanel.setLayout(containerPanelLayout); containerPanelLayout.setHorizontalGroup( containerPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGap(0, 374, Short.MAX_VALUE) ); containerPanelLayout.setVerticalGroup( containerPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGap(0, 239, Short.MAX_VALUE) ); changerButton.setText("Change to 3D"); changerButton.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { changerButtonActionPerformed(evt); } }); javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane()); getContentPane().setLayout(layout); layout.setHorizontalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addComponent(containerPanel, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) .addComponent(changerButton)) .addContainerGap()) ); layout.setVerticalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addComponent(containerPanel, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED) .addComponent(changerButton) .addContainerGap()) ); pack(); } } (My apologies for the Netbeans generated GUI code) I should mention that when we call parent.remove(view2D) and parent.add(view3D) to change the views the X Windows ID of our 3D view changes and we're unable to get our 3D view back. Therefore parent.remove(view2D) and parent.add(view3D) is not really a solution and we have to call setVisible(false) and setVisible(true) on the JComponents that contain our 2D and 3D views in order to hide and show them. Any help will be greatly appreciated.

  • Record audio via MediaRecorder

    - by Isuru Madusanka
    I am trying to record audio by MediaRecorder, and I get an error, I tried to change everything and nothing works. Last two hours I try to find the error, I used Log class too and I found out that error occurred when it call recorder.start() method. What could be the problem? public class AudioRecorderActivity extends Activity { MediaRecorder recorder; File audioFile = null; private static final String TAG = "AudioRecorderActivity"; private View startButton; private View stopButton; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); startButton = findViewById(R.id.start); stopButton = findViewById(R.id.stop); setContentView(R.layout.main); } public void startRecording(View view) throws IOException{ startButton.setEnabled(false); stopButton.setEnabled(true); File sampleDir = Environment.getExternalStorageDirectory(); try{ audioFile = File.createTempFile("sound", ".3gp", sampleDir); }catch(IOException e){ Toast.makeText(getApplicationContext(), "SD Card Access Error", Toast.LENGTH_LONG).show(); Log.e(TAG, "Sdcard access error"); return; } recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setAudioEncodingBitRate(16); recorder.setAudioSamplingRate(44100); recorder.setOutputFile(audioFile.getAbsolutePath()); recorder.prepare(); recorder.start(); } public void stopRecording(View view){ startButton.setEnabled(true); stopButton.setEnabled(false); recorder.stop(); recorder.release(); addRecordingToMediaLibrary(); } protected void addRecordingToMediaLibrary(){ ContentValues values = new ContentValues(4); long current = System.currentTimeMillis(); values.put(MediaStore.Audio.Media.TITLE, "audio" + audioFile.getName()); values.put(MediaStore.Audio.Media.DATE_ADDED, (int)(current/1000)); values.put(MediaStore.Audio.Media.MIME_TYPE, "audio/3gpp"); values.put(MediaStore.Audio.Media.DATA, audioFile.getAbsolutePath()); ContentResolver contentResolver = getContentResolver(); Uri base = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI; Uri newUri = contentResolver.insert(base, values); sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, newUri)); Toast.makeText(this, "Added File" + newUri, Toast.LENGTH_LONG).show(); } } And here is the xml layout. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <Button android:id="@+id/start" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="146dp" android:onClick="startRecording" android:text="Start Recording" /> <Button android:id="@+id/stop" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/start" android:layout_below="@+id/start" android:layout_marginTop="41dp" android:enabled="false" android:onClick="stopRecording" android:text="Stop Recording" /> </RelativeLayout> And I added permission to AndroidManifest file. <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="in.isuru.audiorecorder" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".AudioRecorderActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.RECORD_AUDIO" /> </manifest> I need to record high quality audio.

  • Creating a file upload template in Doctrine ORM

    - by balupton
    Hey all. I'm using Doctrine 1.2 as my ORM for a Zend Framework Project. I have defined the following Model for a File. File: columns: id: primary: true type: integer(4) unsigned: true code: type: string(255) unique: true notblank: true path: type: string(255) notblank: true size: type: integer(4) type: type: enum values: [file,document,image,video,audio,web,application,archive] default: unknown notnull: true mimetype: type: string(20) notnull: true width: type: integer(2) unsigned: true height: type: integer(2) unsigned: true Now here is the File Model php class (just skim through for now): <?php /** * File * * This class has been auto-generated by the Doctrine ORM Framework * * @package ##PACKAGE## * @subpackage ##SUBPACKAGE## * @author ##NAME## <##EMAIL##> * @version SVN: $Id: Builder.php 6365 2009-09-15 18:22:38Z jwage $ */ class File extends BaseFile { public function setUp ( ) { $this->hasMutator('file', 'setFile'); parent::setUp(); } public function setFile ( $file ) { global $Application; // Configuration $config = array(); $config['bal'] = $Application->getOption('bal'); // Check the file if ( !empty($file['error']) ) { $error = $file['error']; switch ( $file['error'] ) { case UPLOAD_ERR_INI_SIZE : $error = 'ini_size'; break; case UPLOAD_ERR_FORM_SIZE : $error = 'form_size'; break; case UPLOAD_ERR_PARTIAL : $error = 'partial'; break; case UPLOAD_ERR_NO_FILE : $error = 'no_file'; break; case UPLOAD_ERR_NO_TMP_DIR : $error = 'no_tmp_dir'; break; case UPLOAD_ERR_CANT_WRITE : $error = 'cant_write'; break; default : $error = 'unknown'; break; } throw new Doctrine_Exception('error-application-file-' . $error); return false; } if ( empty($file['tmp_name']) || !is_uploaded_file($file['tmp_name']) ) { throw new Doctrine_Exception('error-application-file-invalid'); return false; } // Prepare config $file_upload_path = realpath($config['bal']['files']['upload_path']) .

So hopefully I can do something like: File: actAs: BalFile: columns: id: primary: true type: integer(4) unsigned: true code: type: string(255) unique: true notblank: true path: type: string(255) notblank: true size: type: integer(4) type: type: enum values: [file,document,image,video,audio,web,application,archive] default: unknown notnull: true mimetype: type: string(20) notnull: true width: type: integer(2) unsigned: true height: type: integer(2) unsigned: true I'm hoping for a validator so that say if I do $File->setFile($_FILE['uploaded_file']); It will provide a validation error, except in all the doctrine documentation it has little on custom validators, especially in the contect of "virtual" fields. So in summary, my question is: How earth can I go about making a template/extension to porting this functionality? I have tried before with templates but always gave up after a day :/ If you could take the time to port the above I would greatly appreciate it.

  • Java RMI cannot connect to host from external client.

    - by Koe
    I've been using RMI in this project for a while. I've gotten the client program to connect (amongst other things) to the server when running it over my LAN, however when running it over the internet I'm running into the following exception: java.rmi.ConnectException: Connection refused to host: (private IP of host machine); nested exception is: java.net.ConnectException: Connection timed out: connect at sun.rmi.transport.tcp.TCPEndpoint.newSocket(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.createConnection(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.newConnection(Unknown Source) at sun.rmi.server.UnicastRef.invoke(Unknown Source) at java.rmi.server.RemoteObjectInvocationHandler.invokeRemoteMethod(Unknown Source) at java.rmi.server.RemoteObjectInvocationHandler.invoke(Unknown Source) at $Proxy1.ping(Unknown Source) at client.Launcher$PingLabel.runPing(Launcher.java:366) at client.Launcher$PingLabel.<init>(Launcher.java:353) at client.Launcher.setupContentPane(Launcher.java:112) at client.Launcher.<init>(Launcher.java:99) at client.Launcher.main(Launcher.java:59) Caused by: java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.<init>(Unknown Source) at java.net.Socket.<init>(Unknown Source) at sun.rmi.transport.proxy.RMIDirectSocketFactory.createSocket(Unknown Source) at sun.rmi.transport.proxy.RMIMasterSocketFactory.createSocket(Unknown Source) ... 12 more This error is remeniscent of my early implementation of RMI and I can obtain the error verbatum if I run the client locally without the server program running as well. To me Connection Timed Out means a problem with the server's response. Here's the client initiation: public static void main(String[] args) { try { String host = "<WAN IP>"; Registry registry = LocateRegistry.getRegistry(host, 1099); Login lstub = (Login) registry.lookup("Login Server"); Information istub = (Information) registry.lookup("Game Server"); new Launcher(istub, lstub); } catch (RemoteException e) { System.err.println("Client exception: " + e.toString()); e.printStackTrace(); } catch (NotBoundException e) { System.err.println("Client exception: " + e.toString()); e.printStackTrace(); } } Interestingly enough no Remote Exception is thrown here. Here's the server initiation: public static void main(String args[]) { try { GameServer gobj = new GameServer(); Information gstub = (Information) UnicastRemoteObject.exportObject( gobj, 1099); Registry registry = LocateRegistry.createRegistry(1099); registry.bind("Game Server", gstub); LoginServer lobj = new LoginServer(gobj); Login lstub = (Login) UnicastRemoteObject.exportObject(lobj, 7099); // Bind the remote object's stub in the registry registry.bind("Login Server", lstub); System.out.println("Server ready"); } catch (Exception e) { System.err.println("Server exception: " + e.toString()); e.printStackTrace(); } } Bad practice with the catch(Exception e) I know but bear with me. Up to this stage I know it works fine over the LAN, here's where the exception occurs over the WAN and is the first place a method in the server is called: private class PingLabel extends JLabel { private static final long serialVersionUID = 1L; public PingLabel() { super(""); runPing(); } public void setText(String text) { super.setText("Ping: " + text + "ms"); } public void runPing() { try { PingThread pt = new PingThread(); gameServer.ping(); pt.setRecieved(true); setText("" + pt.getTime()); } catch (RemoteException e) { e.printStackTrace(); } } } That's a label placed on the launcher as a ping test. the method ping(), in gameserver does nothing, as in is a null method. It's worth noting also that ports 1099 and 7099 are forwarded to the server machine (which should be obvious from the stack trace). Can anyone see anyting I'm missing/doing wrong? If you need any more information just ask. EDIT: I'm practically certain the problem has nothing to do with my router settings. When disabling my port forwarding settings I get a slightly different error: Client exception: java.rmi.ConnectException: Connection refused to host: (-WAN IP NOT LOCAL IP-); but it appears both on the machine locally connected to the server and on the remote machine. In addition, I got it to work seamlessly when connecting the server straight tho the modem (cutting out the router. I can only conclude the problem is in my router's settings but can't see where (I've checked and double checked the port forwarding page). That's the only answer i can come up with.

  • Threads to make video out of images

    - by masood
    updates: I think/ suspect the imageIO is not thread safe. shared by all threads. the read() call might use resources that are also shared. Thus it will give the performance of a single thread no matter how many threads used. ? if its correct . what is the solution (in practical code) Single request and response model at one time do not utilizes full network/internet bandwidth, thus resulting in low performance. (benchmark is of half speed utilization or even lower) This is to make a video out of an IP cam that gives a new image on each request. http://149.5.43.10:8001/snapshot.jpg It makes a delay of 3 - 8 seconds no matter what I do. Changed thread no. and thread time intervals, debugged the code by System.out.println statements to see if threads work. All seems normal. Any help? Please show some practical code.

  • Why doesn't JFreeCharts correctly connect the points in my xy-line graph?

    - by Javajava
    /Each letter A,T,G,C represents a direction for the plot to graph. Specifically, “A” means move right, “T” is move down, “C” is move up, and “G” is move left.

  • Understanding the passing of data/life of a script in web development/CodeIgniter

    - by Pete Jodo
    I hope I worded the title accurately enough but I typically use Java and don't have much experience in Web Development/PHP/CodeIgniter. I have a difficult time understanding the life cycle of a script as I found out trying to implement a certain feature to a website I am developing (as a means of learning how to). I'll first describe the feature I tried implementing and then the problem I ran into that made me question my fundamental understanding of how scripts work since I'm used to typical OOP. Ok so here goes... I have a webpage that has 2 basic tasks a user can do, create and delete an entry. What I attempted to implement was a way to time a user how long it takes them to complete a certain task. The way I did this was have a homepage where there would be a list of tasks a user to choose from (in this case 2, create and delete). A user would click a task which would link to the 'true' homepage where the user then would be expected to complete the task. My script looks like this: <?php class Site extends CI_Controller { var $task1; var $tasks = array( "task1" => NULL, "date1" => 0, "date2" => 0, "diff" => 0); function __construct() { parent::__construct(); include 'timetask.php'; $this->task1 = new TimeTask("create"); } function index() { $this->tasks['task1'] = $this->task1->getTask(); $this->tasks['diff'] = $this->task1->getTimeDiff(); if($this->tasks['diff'] == NULL) { $this->tasks['diff'] = 0; } $this->load->view('usability_test', $this->tasks); } function origIndex() { $this->task1->setDate1(new DateTime()); $this->tasks['date1'] = $this->task1->getDate1()->getTimestamp(); $data = array(); if($q = $this->site_model->get_records()) { $data['records'] = $q; } $this->load->view('options_view', $data); } function create() { $this->task1->setDate2(new DateTime()); $this->tasks['date2'] = $this->task1->getDate2()->getTimestamp(); $data = array( 'author' => $this->input->post('author'), 'title' => $this->input->post('title'), 'contents' => $this->input->post('contents') ); $this->site_model->add_record($data); $this->index(); } I only included create to keep it short. Then I also have the TimeTask class, that actually another StackOverflow so kindly helped me with: <?php class TimeTask { private $task; /** * @var DateTime */ private $date1, $date2; function __construct($currTask) { $this->task = $currTask; } public function getTimeDiff() { $hasDiff = $this->date1 && $this->date2; if ($hasDiff) { return $this->date2->getTimestamp() - $this->date1->getTimestamp(); } else { return NULL; } } public function __toString() { return (string) $this->getTimeDiff(); } /** * @return \DateTime */ public function getDate1() { return $this->date1; } /** * @param \DateTime $date1 */ public function setDate1(DateTime $date1) { $this->date1 = $date1; } /** * @return \DateTime */ public function getDate2() { return $this->date2; } /** * @param \DateTime $date2 */ public function setDate2(DateTime $date2) { $this->date2 = $date2; } /** * @return get current task */ public function getTask() { return $this->task; } } ?> I don't think posting the views is necessary for the question but here is atleast how the links are made. ...and... id", $row-title); ? Now there's no error in the code but it doesn't do what I expect of it and the reason I assume why is because that each time a function of the script is called via a new page it is NOT the same instance of the script called previously so any previously created objects are no longer there. This confuses me and leaves me quite unsure of how to implement this gracefully. Some ways I would guess of how to do this is by passing the necessary data through the URL or have data saved in a database and retrieve it later to compare the times. What would be a recommended way to do, not just this, but anything that needs previously created data? Also, am I correct to think that a script is only 'alive' for one webpage at a time? Thanks!

  • can i add textfields in the code other than in the init?

    - by themanepalli
    Im a 15 year old noob to java. I am trying to make a basic program trader that asks for the stock price, the stock name, the stock market value and the type of order. Based on the type of order, i want a new textfield to appear. do i have to add the textfield in the init first or can i do it in the action performed. I googled someother ones but they are a little too complicated for me. heres my code. import java.awt.*; import java.applet.*; // import an extra class for the ActionListener import java.awt.event.*; public class mathFair extends Applet implements ActionListener { TextField stockPrice2; TextField stockName2; TextField orderType2; TextField marketValue2; TextField buyOrder2; TextField sellOrder2; TextField limitOrder2; TextField stopLossOrder2; Label stockPrice1; Label stockName1; Label orderType1; Label marketValue1; Label buyOrder1; Label sellOrder1; Label limitOrder1; Label stopLossOrder1; Button calculate; public void init() { stockPrice1 = new Label ("Enter Stock Price:"); stockName1 = new Label ("Enter Name of Stock: "); orderType1 = new Label ("Enter Type of Order: 1 for Buy, 2 for Sell, 3 for Stop Loss, 4 for Limit"); marketValue1= new Label("Enter The Current Price Of The Market"); stopLossOrder1 = new Label ("Enter The Lowest Price The Stock Can Go"); limitOrder1 = new Label ("Enter The Highest Price The Stock Can Go"); stockPrice2 = new TextField (35); stockName2 = new TextField (35); orderType2 = new TextField (35); marketValue2= new TextField(35); calculate= new Button("Start The Simulation"); add (stockPrice1); add (stockPrice2); add (stockName1); add (stockName2); add (marketValue1); ; add(marketValue2); add (orderType1); add (orderType2); add(calculate); ; calculate.addActionListener(this); } public void actionPerformed (ActionEvent e) { String stock= stockPrice2.getText(); int stockPrice= Integer.parseInt(stock); stockPrice2.setText(stockPrice +""); String marketV= marketValue2.getText(); int marketValue= Integer.parseInt(marketV); marketValue2.setText(marketValue+""); String orderT= orderType2.getText(); int orderType= Integer.parseInt(orderT); orderType2.setText(orderType+""); if((e.getSource()==calculate)&& (orderType==1)) { buyOrder2= new TextField(35); buyOrder1 = new Label("Enter Price You Would Like To Buy At"); add(buyOrder2); add(buyOrder1); } else if((e.getSource()==calculate)&& (orderType==2)) { sellOrder2= new TextField(35); sellOrder1 = new Label("Enter Price You Would Like To Sell At"); add(sellOrder2); add(sellOrder1); } else if((e.getSource()==calculate)&& (orderType==3)) { stopLossOrder2= new TextField(35); stopLossOrder1=new Label("Enter The Lowest Price The Stock Can Go"); add(stopLossOrder2); add(stopLossOrder1); } else if((e.getSource()==calculate)&& (orderType==4)) { limitOrder2=new TextField(35); limitOrder1= new Label("Enter the Highest Price The Stock Can Go"); add(limitOrder2); add(limitOrder1);; } } }

  • Java Program Compiles and Runs, but doesn't work

    - by Richard Long
    When I run this program I enter information in a text box, push the search button, but nothing happens. The program just sits there until I press Cntrl C to break it. It looks like it should work, but I can't figure out what is hanging the program up. Here is the code: First class: import java.io.*; import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.util.*; public class NameGameFrame extends JFrame { public static String name; static JTextField textfield = new JTextField(20); static JTextArea textarea = new JTextArea(30,30); public static String num; public static String [] fields; public static int [] yearRank; public static boolean match; public static int getInts, marker, year, max; public static void main( String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setTitle("Name Game"); frame.setLocation(500,400); frame.setSize(800,800); JPanel panel = new JPanel(new GridBagLayout()); GridBagConstraints c = new GridBagConstraints(); JLabel label = new JLabel("Enter the Name or Partial Name to search:"); c.gridx = 0; c.gridy = 0; c.insets = new Insets(2,2,2,2); panel.add(label,c); c.gridx = 0; c.gridy = 1; panel.add(textarea,c); JButton button = new JButton("Search"); c.gridx = 1; c.gridy = 1; panel.add(button,c); c.gridx = 1; c.gridy = 0; panel.add(textfield,c); frame.getContentPane().add(panel, BorderLayout.NORTH); frame.pack(); frame.setVisible(true); button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { name = textfield.getText(); java.io.File file = new java.io.File("namesdata.txt"); try { Scanner input = new Scanner(file); num = input.nextLine(); NameRecord nr = new NameRecord(name); while (input.hasNext()) { if(match = num.toLowerCase().contains(name.toLowerCase())) { nr.getRank(); nr.getBestYear(marker); } } } catch(FileNotFoundException e) { System.err.format("File does not exist\n"); } textarea.setText(fields[0]); } }); } } This is the second class: import java.io.*; import java.util.*; public class NameRecord { public NameRecord( String name) { } public static int getBestYear(int marker) { switch (marker) { case 1: year = 1900; break; case 2: year = 1910; break; case 3: year = 1920; break; case 4: year = 1930; break; case 5: year = 1940; break; case 6: year = 1950; break; case 7: year = 1960; break; case 8: year = 1970; break; case 9: year = 1980; break; case 10: year = 1990; break; case 11: year = 2000; break; } return year; } public static int getRank() { fields = num.split(" "); max = 0; for (int i = 1; i<12; i++) { getInts = Integer.parseInt(fields[i]); if(getInts>max) { max = getInts; marker = i; } } return max; } }

  • Android Video Camera : still picture

    - by Alex
    I use the camera intent to capture video. Here is the problem: If I use this line of code, I can record video. But onActivityResult doesn't work. Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); If I use this line of code, after press the recording button, the camera is freezed, I mean, the picture is still. Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); BTW, when I use $Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); to capture a picture, it works fine. The java file is as follows: package com.camera.picture; import java.io.File; import java.text.SimpleDateFormat; import java.util.Date; import android.app.Activity; import android.content.ContentValues; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.os.Environment; import android.provider.MediaStore; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.Toast; import android.widget.VideoView; public class PictureCameraActivity extends Activity { private static final int IMAGE_CAPTURE = 0; private static final int VIDEO_CAPTURE = 1; private Button startBtn; private Button videoBtn; private Uri imageUri; private Uri videoUri; private ImageView imageView; private VideoView videoView; /** Called when the activity is first created. * sets the content and gets the references to * the basic widgets on the screen like * {@code Button} or {@link ImageView} */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imageView = (ImageView)findViewById(R.id.img); videoView = (VideoView)findViewById(R.id.videoView); startBtn = (Button) findViewById(R.id.startBtn); startBtn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { startCamera(); } }); videoBtn = (Button) findViewById(R.id.videoBtn); videoBtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub startVideoCamera(); } }); } public void startCamera() { Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testphoto.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); values.put(MediaStore.Images.Media.DESCRIPTION, "Image capture by camera"); values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg"); imageUri = getContentResolver().insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); startActivityForResult(intent, IMAGE_CAPTURE); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == IMAGE_CAPTURE) { if (resultCode == RESULT_OK){ Log.d("ANDROID_CAMERA","Picture taken!!!"); imageView.setImageURI(imageUri); } } if (requestCode == VIDEO_CAPTURE) { if (resultCode == RESULT_OK) { Log.d("ANDROID_CAMERA","Video taken!!!"); Toast.makeText(this, "Video saved to:\n" + data.getData(), Toast.LENGTH_LONG).show(); videoView.setVideoURI(videoUri); } } } private void startVideoCamera() { // TODO Auto-generated method stub //create new Intent Log.d("ANDRO_CAMERA", "Starting camera on the phone..."); String fileName = "testvideo.mp4"; ContentValues values = new ContentValues(); values.put(MediaStore.Video.Media.TITLE, fileName); values.put(MediaStore.Video.Media.DESCRIPTION, "Video captured by camera"); values.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4"); videoUri = getContentResolver().insert( MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent("android.media.action.VIDEO_CAMERA"); //Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); // start the Video Capture Intent startActivityForResult(intent, VIDEO_CAPTURE); } private static File getOutputMediaFile() { // TODO Auto-generated method stub // To be safe, you should check that the SDCard is mounted // using Environment.getExternalStorageState() before doing this.

  • Clicking Elements in Android Doesn't Display the Correct Values

    - by Devin
    I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment. I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value). There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code: package com.TicTacToe.app; import com.TicTacToe.app.R; //Other import statements public class TicTacToe extends Activity { public String player = "X"; public int ALERT_ID; public int buttonId; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //Sets up instances of UI elements final TextView playerText = (TextView)findViewById(R.id.CurrentPlayerDisp); final Button button = (Button) findViewById(R.id.SetPlayer); final TextView location1 = (TextView)findViewById(R.id.location1); final TextView location2 = (TextView)findViewById(R.id.location2); final TextView location3 = (TextView)findViewById(R.id.location3); final TextView location4 = (TextView)findViewById(R.id.location4); final TextView location5 = (TextView)findViewById(R.id.location5); final TextView location6 = (TextView)findViewById(R.id.location6); final TextView location7 = (TextView)findViewById(R.id.location7); final TextView location8 = (TextView)findViewById(R.id.location8); final TextView location9 = (TextView)findViewById(R.id.location9); playerText.setText(player); //Handlers for events button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // Perform action on click if (player.equals("X")){ player = "O"; playerText.setText(player); } else if(player.equals("O")){ player = "X"; playerText.setText(player); } //Sets up the dialog buttonId = 0; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 1; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 2; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location3.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 3; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location4.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 4; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location5.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 5; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location6.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 6; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location7.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 7; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location8.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 8; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location9.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 9; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); } protected Dialog onCreateDialog(int id){ String msgString = "You are on spot " + buttonId; AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage(msgString) .setCancelable(false) .setNeutralButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); return alert; } }

  • Creating a custom categories widget

    - by Scott B
    The code below is an attempt to take the WP_Widget_Categories class and use it as the basis for a custom categories widget based on the default categories widget. I'm getting no output however and the widget is not showing up in the "Available Widgets" listing. What am I doing wrong? <?php /* Plugin Name: My Categories Widget Version: 1.0 */ class MY_Widget_Categories extends WP_Widget { function MY_Widget_Categories() { $widget_ops = array( 'classname' => 'widget_categories', 'description' => __( "A list or dropdown of categories" ) ); $this->WP_Widget('categories', __('Categories'), $widget_ops); } function widget( $args, $instance ) { extract( $args ); $title = apply_filters('widget_title', empty( $instance['title'] ) ? __( 'Categories' ) : $instance['title']); $c = $instance['count'] ? '1' : '0'; $h = $instance['hierarchical'] ? '1' : '0'; $d = $instance['dropdown'] ? '1' : '0'; echo $before_widget; if ( $title ) echo $before_title . $title . $after_title; $cat_args = array('orderby' => 'name', 'show_count' => $c, 'hierarchical' => $h); if ( $d ) { $cat_args['show_option_none'] = __('Select Category'); wp_dropdown_categories(apply_filters('widget_categories_dropdown_args', $cat_args)); ?> <script type='text/javascript'> /* <![CDATA[ */ var dropdown = document.getElementById("cat"); function onCatChange() { if ( dropdown.options[dropdown.selectedIndex].value > 0 ) { location.href = "<?php echo get_option('home'); ?>/?cat="+dropdown.options[dropdown.selectedIndex].value; } } dropdown.onchange = onCatChange; /* ]]> */ </script> <?php } else { ?> <ul> <?php $cat_args['title_li'] = ''; wp_list_categories(apply_filters('widget_categories_args', $cat_args)); ?> </ul> <?php } echo $after_widget; } function update( $new_instance, $old_instance ) { $instance = $old_instance; $instance['title'] = strip_tags($new_instance['title']); $instance['count'] = $new_instance['count'] ? 1 : 0; $instance['hierarchical'] = $new_instance['hierarchical'] ? 1 : 0; $instance['dropdown'] = $new_instance['dropdown'] ? 1 : 0; return $instance; } function form( $instance ) { //Defaults $instance = wp_parse_args( (array) $instance, array( 'title' => '') ); $title = esc_attr( $instance['title'] ); $count = isset($instance['count']) ? (bool) $instance['count'] :false; $hierarchical = isset( $instance['hierarchical'] ) ? (bool) $instance['hierarchical'] : false; $dropdown = isset( $instance['dropdown'] ) ?
