  • How to create 3 equally wide TextView which fill parent across the screen

    - by hap497
    HI, Can you please tell me how can I create 3 equally wide TextView which fill parent across the screen? I tried doing this, but the width of the TextView are different: it is 149, 89, 89. <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:stretchColumns="*" android:shrinkColumns="*"> <TextView android:id="@+id/t1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_column="0"/> <TextView android:id="@+id/t2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_column="1"/> <TextView android:id="@+id/t3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_column="2"/>

  • Showing ImageView next to TextView in a ListView

    - by KDEx
    So I have a listview that is displaying correctly. When the item is "turned on" the text is white and when it's turned off it's grey. That part all functions great. However when I add the ImageView into the mix I get a null pointer exception. I don't understand why. I've tried using bitmaps as well and get the same problem. Here is some code: @Override public void bindView(View view, Context context, Cursor cursor) { TextView rRule = (TextView) view.findViewById(R.id.rule_text); TextView rType = (TextView) view.findViewById(R.id.rule_type); ImageView iChecked = (ImageView) view.findViewById(R.id.checkBox); String ruleName = cursor.getString(1); int ruleType = cursor.getInt(2); String ruleEnabled = cursor.getString(3); switch (ruleType) { /*...some irrelevant code */ } if (ruleEnabled.equals("true")) { rRule.setTypeface(null, Typeface.BOLD); rRule.setTextColor(Color.WHITE); iChecked.setVisibility(View.VISIBLE); //line 271 } else if (ruleEnabled.equals("false")) { rRule.setTypeface(null, Typeface.NORMAL); rRule.setTextColor(Color.GRAY); iChecked.setVisibility(View.GONE); } rRule.setText(ruleName); } Per request the error log: (Sorry was under the impression null pointers dont say anything helpful..I know the error is the imageview) 06-29 10:29:02.777: E/AndroidRuntime(29516): FATAL EXCEPTION: main 06-29 10:29:02.777: E/AndroidRuntime(29516): java.lang.NullPointerException 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.company.app.DefaultRulesList$RulesAdapter.bindView(DefaultRulesList.java:271) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.company.app.DefaultRulesList$RulesAdapter.newView(DefaultRulesList.java:284) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.CursorAdapter.getView(CursorAdapter.java:246) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.AbsListView.obtainView(AbsListView.java:2033) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.makeAndAddView(ListView.java:1772) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.fillDown(ListView.java:672) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.fillFromTop(ListView.java:732) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.layoutChildren(ListView.java:1625) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.AbsListView.onLayout(AbsListView.java:1863) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1628) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1486) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.onLayout(LinearLayout.java:1399) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.FrameLayout.onLayout(FrameLayout.java:431) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1628) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1486) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.onLayout(LinearLayout.java:1399) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.FrameLayout.onLayout(FrameLayout.java:431) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1489) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewRootImpl.handleMessage(ViewRootImpl.java:2442) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.os.Handler.dispatchMessage(Handler.java:99) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.os.Looper.loop(Looper.java:137) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.app.ActivityThread.main(ActivityThread.java:4424) 06-29 10:29:02.777: E/AndroidRuntime(29516): at java.lang.reflect.Method.invokeNative(Native Method) 06-29 10:29:02.777: E/AndroidRuntime(29516): at java.lang.reflect.Method.invoke(Method.java:511) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 06-29 10:29:02.777: E/AndroidRuntime(29516): at dalvik.system.NativeStart.main(Native Method) Code for iChecked (where the id is called) <ImageView android:id="@+id/checkBox" android:padding="2dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@android:drawable/checkbox_on_background"/>

  • How to show empty view when ListView is empty?

    - by Sheehan Alam
    Here is my layout. For some reason the empty view (TextView in this case) always appears, even when the List is not empty. I thought the ListView would automatically detect when to show the empty view. How can I hook up the empty view properly? <RelativeLayout android:id="@+id/LinearLayoutAR" android:layout_height="fill_parent" android:layout_width="fill_parent"> <ListView android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ARListView"></ListView> <ProgressBar android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/arProgressBar" android:layout_centerHorizontal="true" android:layout_centerVertical="true"></ProgressBar> <!-- Here is the view to show if the list is emtpy --> <TextView android:id="@id/android:empty" android:layout_width="match_parent" android:layout_height="match_parent" android:text="No Results" /> </RelativeLayout>

  • Passing enum or object through an intent (the best solution)

    - by jax
    I have an activity that when started needs access to two different ArrayLists. Both Lists are different Objects I have created myself. Basically I need a way to pass these objects to the activity from an Intent. I can use addExtras() but this requires a Parceable compatible class. I could make my classes to be passed serializable but as I understand this slows down the program. What are my options? Can I pass an Enum? As an an aside: is there a way to pass parameters to an Activity Constructor from an Intent?

  • Android MediaPlayer ignores it's internal volume when the system volume changes

    - by Daniel Flower
    Hi, here is my situation: I have a media player playing music in an Android application. I've found that with certain headphones, the volume is much too loud even when the volume is set to it's lowest setting. As a result, I want to change the volume of the music for all volume levels to be 10% of what it normally is (actually, this value is user-defined of course). The following works perfectly: mediaPlayer.setVolume(0.1f, 0.1f); The volume of the music is now at a good level for listening. However, if the user now changes the volume using the volume rocker (thus changing the music stream volume), the media player changes the volume as expected, but it also seems to reset the 'setVolume' parameters to 1.0, causing a massive volume change. Setting the volume back to 0.1 sets the volume to how it should be (which is 10% of the current music stream volume). To quote the Android docs for the MediaPlayer.setVolume method: This API is recommended for balancing the output of audio streams within an application How can you do this if it gets reset to 1.0 each time the system volume changes? Any help muchly appreciated. Thanks.

    Hi I have an application that calls the android phone's default camera to take photo the following is my code.

  • Changing the Android emulator locale automatically

    - by Christopher
    For automated testing (using Hudson) I have a script that generates a bunch of emulators for many combinations of Android OS version, screen resolution, screen density and language. This works fine, except for the language part. I need to find a way to change the Android system locale automatically. Here's some approaches I can think of, in order of preference: Extracting/editing/repacking a QEMU image directly before starting the emulator Running some sort of system-locale-changing APK on the emulator after startup Changing the locale settings on the emulator filesystem after startup Changing the locale settings in some SQLite DB on the emulator after startup Running a key sequence (via the emulator's telnet interface) that would open the settings app and change the locale Manually starting the emulator for each platform version, changing the locale by hand in the settings, saving it and archiving the images for later deployment Any ideas whether this can be done, either via the above methods or otherwise? Do you know where locale settings are persisted to/read from by the system? Solution: Thanks to dtmilano's info about the relevant properties, and some further investigation on my part, I came up with a solution even better and simpler simpler than all the ideas above! I have updated the answer below with the details.

  • Remove appearance of TextField in droidText : Android

    - by AnujAroshA
    I am trying to create a PDF using droidText library. There I want to place some text content in the middle of the page but align to left. I was unable to do with Paragraph class and setAlignment() method. So I have decided to use TextField class. Below is the code I have used, Document document = new Document(PageSize.A4); try { PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(android.os.Environment.getExternalStorageDirectory() + java.io.File.separator + "TextFields.pdf")); document.open(); TextField tf = new TextField(writer, new Rectangle(100, 300, 200, 350), "Content"); tf.setText("This is the content of text field"); tf.setAlignment(Element.ALIGN_CENTER); tf.setOptions(TextField.MULTILINE | TextField.REQUIRED); PdfFormField field = tf.getTextField(); writer.addAnnotation(field); } catch (DocumentException de) { System.err.println(de.getMessage()); } catch (IOException ioe) { System.err.println(ioe.getMessage()); } document.close(); Code works perfect, but the out put PDF file that I am getting has this TextField which can be editable and also change the font appearance when I am click on the TextField. I don't want that in to my final PDF. How can I remove that attribute? If it is not possible, is there any other way I can position some text in a PDF file using droidText library in Android?

  • AndEngine VS Android's Canvas VS OpenGLES - For rendering a 2D indoor vector map

    - by Orchestrator
    This is a big issue for me I'm trying to figure out for a long time already. I'm working on an application that should include a 2D vector indoor map in it. The map will be drawn out from an .svg file that will specify all the data of the lines, curved lines (path) and rectangles that should be drawn. My main requirement from the map are Support touch events to detect where exactly the finger is touching. Great image quality especially when considering the drawings of curved and diagonal lines (anti-aliasing) Optional but very nice to have - Built in ability to zoom, pan and rotate. So far I tried AndEngine and Android's canvas. With AndEngine I had troubles with implementing anti-aliasing for rendering smooth diagonal lines or drawing curved lines, and as far as I understand, this is not an easy thing to implement in AndEngine. Though I have to mention that AndEngine's ability to zoom in and pan with the camera instead of modifying the objects on the screen was really nice to have. I also had some little experience with the built in Android's Canvas, mainly with viewing simple bitmaps, but I'm not sure if it supports all of these things, and especially if it would provide smooth results. Last but no least, there's the option of just plain OpenGLES 1 or 2, that as far as I understand, with enough work should be able to support all the features I require. However it seems like something that would be hard to implement. And I've never programmed in OpenGL or anything like it, but I'm willing very much to learn. To sum it all up, I need a platform that would provide me with the ability to do the 3 things I mentioned before, but also very important - To allow me to implement this feature as fast as possible. Any kind of answer or suggestion would be very much welcomed as I'm very eager to solve this problem! Thanks!

  • Android application transparency and window sizing at root level

    - by ajoburg
    Is it possible to create an application with a transparent background on the root task such that you can see the task running beneath it when it is part of a separate stack? Alternatively, is it possible to run an application so the window of the root task is only a portion of the screen instead of the whole screen? I understand how the transparency and window sizing is done with activities that are not the root task and this works fine. However, the root task of an activity seems to always fill the whole screen and be black even when a transparent theme is applied to the application object in the manifest file. ApplicationManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true" android:theme="@style/Theme.Transparent"> Styles.xml <resources> <style name="Theme.Transparent"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@drawable/ transparent_background</item> <item name="android:windowAnimationStyle">@android:style/ Animation.Translucent</item> <item name="android:colorForeground">#fff</item> <item name="android:windowIsFloating">true</item> <item name="android:gravity">bottom</item> </style> </resources> Colors.xml <resources> <drawable name="transparent_background">#00000000</drawable> </resources>

  • Why / When / How is this Android serviceBinder resetting to null?

    - by GaZ
    I've written a ListActivity for Android 2.1 which is used to display a list of event categories. As the user selects a category, the program calls a web service to retrieve a list of sub-events. For example, a top level event might be "soccer" and when the user selects this the web service would return various soccer associations (e.g. "english", "french", "german", etc.) and display them in a new list. The following code seems to work occasionally, however sometimes the call to the service (in EventsListTask) fails because the serviceBinder is null.

Is there anything I need to watch out for when doing this? Am I calling the target intent incorrectly?

  • Help regarding Android NDK

    - by Siva Kumar
    I am a beginner in using Android NDK. I am using Eclipse and I installed cygwin to build the c file to generate the .so file But while building the c file in cygwin I am always getting the error make: ***No rule to make target 'file.c' ... .Stop I tried building different C codes but for every file it says the same error .. Here is the source code: public class ndktest extends Activity { static { System.loadLibrary("ndkt"); } private native void helloLog(String logThis); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); helloLog("this is to test log file"); } } file.c void Java_com_ndktest_helloLog(JNIEnv * env, jobject this, jstring logThis) { jboolean isCopy; const char * szLogThis = (*env)->GetStringUTFChars(env, logThis, &isCopy); (*env)->ReleaseStringUTFChars(env, logThis, szLogThis); } And here is my Android.mk LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_LDLIBS := -llog LOCAL_MODULE := ndkt LOCAL_SRC_FILES := file.c include $(BUILD_SHARED_LIBRARY) I searched for the solution for the cause of error ... but nothing works for me.

  • Does android maps support ground overlay?

    - by wmh1108
    I have a weather image I would like to use as an overlay in the google maps android api. I would like to achieve the same result that I get from using GroundOverlay in KML files, such as <GroundOverlay> <name>myimage</name> <Icon> <href>myimage.png</href> <viewBoundScale>0.75</viewBoundScale> </Icon> <LatLonBox> <north>75.6088</north> <south>5.0121</south> <east>182.2805</east> <west>120.6795</west> </LatLonBox> </GroundOverlay> The above will ensure that the 4 corners of my image stay anchored to the 4 lat/long points listed, regardless of scrolling, zooming etc.. Is there a way to accomplish this using the google api/maps provided for android?

  • Android Plugin in Eclipse 3.5 on Ubuntu 64bit got problems with properties

    - by Zordid
    Hi there! I got a huge problem with the Android Development Tools ADT running in Eclipse Galileo (3.5.1) on Ubuntu 9.10, 64bit. On this platform, I do not manage to see any property edit dialogs for layout properties. E.g. the one where you can select a string resource ID for text fields, or a drawable ID for image fields or backgrounds. Whenever I click on the ... button next to the property value - nothing happens, except this button disappears. Properties with a list of possible values, e.g. "wrap_content" or "fill_parent" are displayed in a dropdown box directly in the properties field. On a different system I work in a Windows environment with Eclipse 3.4 and the same ADT: no problems whatsoever, everything works fine, the dialogs come perfectly. Does anyone know what to do here? Where's the problem? Why does Eclipse not tell me that something goes wrong? Thanks! NEW DISCOVERIES: I found out that it might not even be an Android problem, but a general Eclipse problem that I can see with all version (Ganymede, Galileo, Helios) on my Linux (Ubuntu) system. It must be a simple UI problem: the button with ... next to the values does not receive the mouse click!! I managed to see the appropriate dialogs to edit the property values by doubleclicking the button - crazy, strange, ugly behavior! But why on earth does nobody else know about this problem - I cannot find anything else on the net about it! Could it be related to this strange "GDK native window problem" on Gnome? HELP!

  • Android Service setForeground While Display Sleeps

    - by c12
    I have a background Android Service that's purpose is to communicate with another device (non-phone) using a Bluetooth socket. Everything works fine except that the service gets stopped and restarted by the OS when the phone display is sleeping. This restart sometimes leaves a 15-20 minute gaps where there is no communication between the Service and the Bluetooth device and I need to be able to query the device every minute. Is startForeground the proper approach? Attempted to use: startForeground(int, Notification) //still see gaps when phone sleeps Service: public class ForegroundBluetoothService extends Service{ private boolean isStarted = false; @Override public void onDestroy() { super.onDestroy(); stop(); } /** * @see android.app.Service#onBind(android.content.Intent) */ @Override public IBinder onBind(Intent intent) { return null; } /** * @see android.app.Service#onStartCommand(android.content.Intent, int, int) */ @Override public int onStartCommand(Intent intent, int flags, int startId) { loadServiceInForeground(); return(START_STICKY); } private void loadServiceInForeground() { if (!isStarted) { isStarted=true; Notification notification = new Notification(R.drawable.icon, "Service is Running...", System.currentTimeMillis()); Intent notificationIntent = new Intent(this, MainScreen.class); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(this, "Notification Title", "Service is Running...", pendingIntent); startForeground(12345, notification); try{ queryTheBluetoothDevice(); } catch(Exception ex){ ex.printStackTrace(); } } } private void stop() { if (isStarted) { isStarted=false; stopForeground(true); } } }

  • Android: Scheduling application to start with repeating alarms not working

    - by vikramagain
    I get my Broadcast receiver to set a recurring alarm, to fire up a service. Unfortunately this does not result in the service being called repeatedly (based on logcat). I've experimented with different values for the time interval too. Can someone help? (I'm testing through Eclipse on Android 3.2 Motorola xoom) Below is the code for the Broadcast receiver. alarm = (AlarmManager) arg0.getSystemService(Context.ALARM_SERVICE); Intent intentUploadService = new Intent (arg0, com.vikramdhunta.UploaderService.class); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.add(Calendar.SECOND, 3); PendingIntent pi = PendingIntent.getBroadcast(arg0, 0, intentUploadService , 0); alarm.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 5, pi); Below is the code for the Service class public UploaderService() { super("UploaderService"); mycounterid = globalcounter++; } @Override protected void onHandleIntent(Intent intent) { synchronized(this) { try { for (int i = 1;i < 5;i++) { // doesn't do much right now.. but this should appear in logcat Log.i(TAG,"OK " + globalcounter++ + " uploading..." + System.currentTimeMillis()); } } catch(Exception e) { } } } @Override public void onCreate() { super.onCreate(); Log.d("TAG", "Service created."); } @Override public IBinder onBind(Intent arg0) { return null; } @Override public int onStartCommand(Intent intent, int flags, int startId) { Log.i(TAG, "Starting upload service..." + mycounterid); return super.onStartCommand(intent,flags,startId); }

  • Android interacting with HTML5 tutorial?

    - by Adam
    I've been looking at using a WebView to display an HTML5 webpage, where the novel features of the mobile device (GPS, compass, accelerometer, camera, etc) can be fed back into the web page. I was wondering if there were any good tutorials showing these functions interacting with the webview. So far I've found ways for the WebView to send javascript commands to the web page, but those interactions haven't been triggered from outside the web view (such as upon receiving an intent from the GPS or accelerometer). Note: The HTML5 Geolocation API is not what I'm interested in. I'm interested in the web page <- WebView interactions, as noted here: http://android-developers.blogspot.com/2008/09/using-webviews.html

  • Android: Displaying Video on VideoView

    - by AndroidDev93
    I'm trying to display a video in my sdcard on the video view. Here is my code: String name = Environment.getExternalStorageDirectory() + "/test.mp4"; final VideoView videoView = (VideoView)findViewById(R.id.videoView1); videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { public void onPrepared(MediaPlayer arg0) { videoView.start(); } }); videoView.setVideoPath(name); The file I am trying to open is called test.mp4 and its located within the sdcard folder. I get an error saying the application has unfortunately stopped. I would appreciate it if someone could help me. Thanks. EDIT : I used the debugger and found out that I get an InvocationTargetException. The detailed message says that : Failure delivering result ResultInfo{who=null, request=1001, result=-1, data=Intent { dat=file:///mnt/sdcard/test.mp4 }} to activity : java.lang.NullPointerException EDIT : I looked at the logcat again and it seems to give the error at videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { I'm guessing either videoView or MediaPlayer is null.
