  • Adding a button bar at the bottom of ListView upon checkbox select (as in gmail app)??

    - by elto
    I have a ListView with custom adapter. In each row there is a checkbox and couple of textviews. I want user to give option to delete the check marked items, so as soon as soon clicks on one of the checkbox, I want a button bar to slide in from the bottom and stay at the bottom regardless of listview scroll. This is something like the email app behavior of Motorola Cliq and to some extent gmail app itself. I have tried adding a relativelayout (containing buttons) below the listview, which has visibility set to gone initially, but as soon as user checks a button, the visibility changes to "visible". I have added a slide-in animation to it too. It is working but problem is that it is overlapping the last element of the listview which user can not checkmark if the button bar has already become visible. So I tried to set the bottom margin of the listview equal to the height of the button bar when I'm changing the button bar visibility, which solves the problem of overlap, but now the checkbox behavior has gone weird. Clicking on one checkmark tries to checkmark another checkmark in the list for some weird reason. I noticed that this happens because as soon as I change the listview margin, list redraws itself, and during this new call to getView() method of adapter, things mess up. I wanted to ask if anyone has done something like this. What is the best method to add such button bar below list while keeping the slide-in animation intact. Also, What is the footer-view of listview and can that solve my problem?

  • HttpURLConnection! Connection.getInputStream is java.io.FileNotFoundException

    - by user3643283
    I created a method "UPLPAD2" to upload file to server. Splitting my file to packets(10MB). It's OK (100%). But when i call getInputStream, i get FileNotFoundException. I think, in loop, i make new HttpURLConnection to set "setRequestProperty". This is a problem. Here's my code: @SuppressLint("NewApi") public int upload2(URL url, String filePath, OnProgressUpdate progressCallBack, AtomicInteger cancelHandle) throws IOException { HttpURLConnection connection = null; InputStream fileStream = null; OutputStream out = null; InputStream in = null; HttpResponse response = new HttpResponse(); Log.e("Upload_Url_Util", url.getFile()); Log.e("Upload_FilePath_Util", filePath); long total = 0; try { // Write the request. // Read from filePath and upload to server (url) byte[] buf = new byte[1024]; fileStream = new FileInputStream(filePath); long lenghtOfFile = (new java.io.File(filePath)).length(); Log.e("LENGHT_Of_File", lenghtOfFile + ""); int totalPacket = 5 * 1024 * 1024; // 10 MB int totalChunk = (int) ((lenghtOfFile + (totalPacket - 1)) / totalPacket); String headerValue = ""; String contentLenght = ""; for (int i = 0; i < totalChunk; i++) { long from = i * totalPacket; long to = 0; if ((from + totalPacket) > lenghtOfFile) { to = lenghtOfFile; } else { to = (totalPacket * (i + 1)); } to = to - 1; headerValue = "bytes " + from + "-" + to + "/" + lenghtOfFile; contentLenght = "Content-Length:" + (to - from + 1); Log.e("Conten_LENGHT", contentLenght); connection = client.open(url); connection.setRequestMethod("POST"); connection.setRequestProperty("Content-Range", headerValue); connection.setRequestProperty("Content-Length", Long.toString(to - from + 1)); out = connection.getOutputStream(); Log.e("Lenght_Of_File", lenghtOfFile + ""); Log.e("Total_Packet", totalPacket + ""); Log.e("Total_Chunk", totalChunk + ""); Log.e("Header_Valure", headerValue); int read = 1; while (read > 0 && cancelHandle.intValue() == 0 && total < totalPacket * (i + 1)) { read = fileStream.read(buf); if (read > 0) { out.write(buf, 0, read); total += read; progressCallBack .onProgressUpdate((int) ((total * 100) / lenghtOfFile)); } } Log.e("TOTAL_", total + "------" + totalPacket * (i + 1)); Log.e("I_", i + ""); Log.e("LENGHT_Of_File", lenghtOfFile + ""); if (i < totalChunk - 1) { connection.disconnect(); } out.close(); } // Read the response. response.setHttpCode(connection.getResponseCode()); in = connection.getInputStream(); // I GET ERROR HERE. if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) { throw new IOException("Unexpected HTTP response: " + connection.getResponseCode() + " " + connection.getResponseMessage()); } byte[] body = readFully(in); response.setBody(body); response.setHeaderFields(connection.getHeaderFields()); if (cancelHandle.intValue() != 0) { return 1; } JSONObject jo = new JSONObject(response.getBodyAsString()); Log.e("Upload_Body_res_", response.getBodyAsString()); if (jo.has("error")) { if (jo.has("code")) { int errCode = jo.getInt("code"); Log.e("Upload_Had_errcode", errCode + ""); return errCode; } else { return 504; } } Log.e("RESPONE_BODY_UPLOAD", response.getBodyAsString() + ""); return 0; } catch (Exception e) { e.printStackTrace(); Log.e("Http_UpLoad_Response_Exception", e.toString()); response.setHttpCode(connection.getResponseCode()); Log.e("ErrorCode_Upload_Util_Return", response.getHttpCode() + ""); if (connection.getResponseCode() == 200) { return 1; } else if (connection.getResponseCode() == 0) { return 1; } else { return response.getHttpCode(); } // Log.e("ErrorCode_Upload_Util_Return", response.getHttpCode()+""); } finally { if (fileStream != null) fileStream.close(); if (out != null) out.close(); if (in != null) in.close(); } } And Logcat 06-12 09:39:29.558: W/System.err(30740): java.io.FileNotFoundException: http://download-f77c.fshare.vn/upload/NRHAwh+bUCxjUtcD4cn9xqkADpdL32AT9pZm7zaboHLwJHLxOPxUX9CQxOeBRgelkjeNM5XcK11M1V-x 06-12 09:39:29.558: W/System.err(30740): at com.squareup.okhttp.internal.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:187) 06-12 09:39:29.563: W/System.err(30740): at com.fsharemobile.client.HttpUtil.upload2(HttpUtil.java:383) 06-12 09:39:29.563: W/System.err(30740): at com.fsharemobile.fragments.ExplorerFragment$7$1.run(ExplorerFragment.java:992) 06-12 09:39:29.568: W/System.err(30740): at java.lang.Thread.run(Thread.java:856) 06-12 09:39:29.568: E/Http_UpLoad_Response_Exception(30740): java.io.FileNotFoundException: http://download-f77c.fshare.vn/upload/NRHAwh+bUCxjUtcD4cn9xqkADpdL32AT9pZm7zaboHLwJHLxOPxUX9CQxOeBRgelkjeNM5XcK11M1V-x

  • Launching an activity at its current state.

    - by Profete162
    Hello, I am trying to make a task switcher and i succed in it. My only problem is that when I launch activities, they are relaunched as they were new activities ( for instance, I am writing an email, i press home and go into my activity,launch email, and then the app launch the email bout goes back at the inbox and the email is lost) So that's not true multitasking. Here are my steps: 1) getting all the running apps: List<ActivityManager.RunningTaskInfo> allTasks = activityManager.getRunningTasks(30); 2) getting the intent: for (ActivityManager.RunningTaskInfo aTask : allTasks) { Intent i = new Intent(Intent.ACTION_MAIN); i.setComponent(aTask.baseActivity); (...) 3) Launching the application when clicking on the button: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED).addCategory(Intent.CATEGORY_LAUNCHER); monthis.startActivity(intent); ` What is wrong with this code? Should I do something different to get it? Thank a lot for any answer.

  • Activity gets killed while executing the camera intent

    - by BlackRider
    In my app I call the system camera to take a picture, and then handle the result in onActivityResult. You know, the usual. It used to work, but now my calling activity gets killed while I'm taking the picture. Specifically, onDestroy() is called on my activity right after I press the camera shutter. The photo does get taken & saved (I've checked that the file gets written on the SD card). After I accept the photo, instead of returning to the calling activity and invoking onActivityResult, the previous activity in the activity stack gets called. I see no exceptions in the logcat. My custom exception handler doesn't get called. If it matters, my app also includes a service that listens to GPS updates, but I unregister all the receivers in onPause(). Here's the call stack for MyCallingActivity.onDestroy(): Thread [<1> main] (Suspended (breakpoint at line 303 in NewPlaceDetailsActivity)) NewPlaceDetailsActivity.onDestroy() line: 303 ActivityThread.performDestroyActivity(IBinder, boolean, int, boolean) line: 2663 ActivityThread.handleDestroyActivity(IBinder, boolean, int, boolean) line: 2694 ActivityThread.access$2100(ActivityThread, IBinder, boolean, int, boolean) line: 117 BinderProxy(ActivityThread$H).handleMessage(Message) line: 968 ActivityThread$H(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 130 ActivityThread.main(String[]) line: 3687 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 507 ZygoteInit$MethodAndArgsCaller.run() line: 842 ZygoteInit.main(String[]) line: 600 NativeStart.main(String[]) line: not available [native method] This is how I start the camera activity, in case you're wondering: protected void startCamera() { createPhotoDirsIfNeeded(); String fileName = "temp.jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); m_capturedImageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); m_photoFileName = APP_PHOTO_PATH + "/" + DateFormat.format(DATE_FORMAT, Calendar.getInstance().getTime()) + ".jpg"; File picFile = new File(m_photoFileName); if(picFile.exists()) { picFile.delete(); } // start the camera activity Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(picFile)); startActivityForResult(intent, IntentHelper.REQUEST_TAKE_PHOTO); } How can I find out why does my activity get killed, AND removed from the stack instead of being created again?

  • Inserting an element into a sorted list

    - by Russell Cargill
    Ok I'm using getSharedPreferences to store my high score but before I fill it up I wanted to sort the scores into ascending order via and array, but if it finds a Score less than it in the first pos then it wont check the rest for the smallest? //function to add score to array and sort it public void addscoretoarray(int mScore){ for(int pos = 0; pos< score.length; pos++){ if(score[pos] > mScore){ //do nothing }else { //Add the score into that position score[pos] = mScore; break; } } sortArray(score); } should I call sortArray() before and after the loop to fix this problem or is there a better method to achive the same results? I should also mention that the sortArray(score) funtion is just calling Arrays.sort(score) where score is an array of mScore

  • camera picturecallback intent not work

    - by Simon
    After I take the photo, the program automatically goes back like onBackPressed(). When I remove the putExtra, the intent runs. When I put startActivity() after takePicture(), it transfers null data.... I just want to put the image data to another activity to have other use. How can it be achieved? private PictureCallback picture = new PictureCallback(){ @Override public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub Intent intent = new Intent(CameraFilming.this, PhotoPreview.class); intent.putExtra("imageByte", data); //Picture data transfer to next activity startActivity(intent); } }; //take photo by pressing button private class captureBtnListener implements View.OnClickListener{ @Override public void onClick(View v){ capture.setOnClickListener(null); CountDownTimer timer = new CountDownTimer(10000, 1000){ @Override public void onTick(long millisUntilFinished) { // TODO Auto-generated method stub countdown.setText(millisUntilFinished/1000+""); } @Override public void onFinish() { // TODO Auto-generated method stub countdown.setText("0"); camera.takePicture(null, null, picture); } }; timer.start(); } } public class PhotoPreview extends Activity{ private RelativeLayout layout; private ImageView overlay, texture, face1, face2; @Override public void onCreate (Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.photo_preview); layout = (RelativeLayout)findViewById(R.id.preview_layout); byte[] data = getIntent().getByteArrayExtra("imageByte"); if (data == null){ Log.d("PhotoPreview", "no image data"); finish(); } Bitmap rawPhotoBitmap = BitmapFactory.decodeByteArray(data, 0, data.length); ImageProcess imgProcess = new ImageProcess(this); Bitmap resizedFace = imgProcess.scaleAccordingWidth(imgProcess.cropImage(rawPhotoBitmap, 840, 125, 440, 560), 77); face1 = new ImageView(this); face1.setImageBitmap(resizedFace); Log.d("testing", "testing"); } }

  • When I get the Force Close dialog, I have a Report button. Where did it come from?

    - by BenTobin
    I feel a little bit silly asking this, but I haven't been able to find any answers on my own. My Force Close dialog has a "Report" button. I think it's a great idea, and I wish everyone had it. At first, I thought it must be something I turned on without realizing it, but not only can't I find any setting that I might have touched, I also can't find any reference to this button existing on the Internet. I have a Droid, and I know 4 other people with Droids, and they say they don't have the option to report Force Closes. Am I special? Am I just missing something? The "report" button has been there for at least a few weeks now. When I use the Report button, I get a screen with a "feedback" field and a checkbox for "Include system data". Below that , it says "Information from feedback reports will be shown to the developer of the application." Under that are Preview and Send buttons. As a developer, I've never received one of these reports. I'd try to send a report to myself, but it seemingly only shows the button for apps installed from the market, and I don't know of a way to crash my production app. I suppose I could publish a simple crashing app just to try it out, but I thought I'd ask you folks first. Edit: You can view screenshots here: http://bentobin.com/crashReportImages/

  • Dismiss a custom dialog?

    - by YaW
    Hi, I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code: //Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.custom_dialog_simple, (ViewGroup) findViewById(R.id.rlDialogSimple)); //Change Text and on click TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple); tvDialogSimple.setText(R.string.avisoComprobar); Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple); btDialogSimple.setOnClickListener(new OnClickListener() { public void onClick(View v) { //Do some stuff //Here i want to close the dialog } }); AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this); builder.setView(layout); AlertDialog alert = builder.create(); alert.show(); So, i want to dismiss the dialog in the onClick of btDialogSimple. How i can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so i don't want to make a builder.setPositiveButton. Any ideas?

  • How to Use Eclipse to Debug JNI code (Java & C/C++)

    - by tkryger
    While I can debug my application with the Eclipse JDT debugger for Java code and GDB for C code, I would prefer to use a single tool for all my debugging. I found several projects that enable "mixed-mode" debugging in Eclipse and include support for single stepping between Java and native code. Intel's Integrated Debugger for Java/JNI Environments Mariot Chauvin's Summer of Code Project: Support Seamless Debugging between JDT & CDT Unfortunately, one claims to be pre-release quality and the other is currently unmaintained. Are there any plug-ins that bring mixed mode debugging functionality to Eclipse in a reliable way or should I continue to use two separate debuggers?

  • How can you tell if an activity is starting or resuming?

    - by Joren
    I have an activity which pulls some JSON from my server, and then uses it to draw a list. That list launches further activities. My problem is that I can't figure out a way to tell if the activity is still alive when you go back to it, so I end up re-querying my JSON from the server and redrawing the list every time the user goes back to the activity. How can I tell if my activity is still alive so I can skip the redraw? Using onRestart works for hitting the home key then going back, but onCreate not onRestart is called if I selected a list item then hit back.

  • Can an app delete its own internal resources?

    - by user637884
    I am trying to find a way to delete an internal resource after an app installs. More specifically, I have a zip file included in the apk, that I unzip to the SD Card when the app is first run. But then want to delete the now unneeded zip file (the purpose being to save the user internal phone memory). I access the zip file with, Resources resources = this.getResources(); InputStream is = resources.openRawResource(R.raw.assets); But am uncertain how to then delete the resource (if even possible). I know one may ask why not simply install the app to SD Card at download. But the app includes a screen widget, and installing apps to the SD Card and using a screen widget is problematic. Thanks, Matt

  • Method with throws Exception: Where is it actually handled?

    - by Esq
    Here is an example code, I am throwing an exception here, it works perfectly fine without the try/catch block of code for some reason. Do I have to handle this inside this method "EntryDelete" or Do I have to handle this where the method is called from? If so can I see an example, what do I have to import in there? What is the acceptable syntax or method to do this? public boolean EntryDelete(int entryId) throws SQLException{ this.open(); kDatabase.delete(kENTRY_TABLE, kENTRY_ENTRY_ID + "=" + entryId, null); this.close(); return true; } Thanks
