  • Adding multiple views to a listview.

    - by hwrdprkns
    Hey guys, I tried to add these views to list view using this kind of factory but everytime I try and add the view to a ListActivity, it comes up with nothing. What am I doing wrong? I set my list views like so: List<View> views = new ArrayList<View>(); for(int x =0;x<tagg_views.size();x++) { lv.addHeaderView(views.get(x)); }

  • Icon backdrop on Samsung Galaxy S? how to change this?

    - by AKh
    Hi all, I see a backdrop being added to my launch icon on the Samsung Galaxy S devices. I need this backdrop changed to a custom backdrop which we created. I know this can be changed since apps like"Daily Briefing" have their own cloud like backdrop making the launch icon look really rich. If anyone does know how to change this backdrop please let me know. I am talking about the background image set behind the icons. Eg: in the below image on the 1st row can you notice the yellow backdrop for Memo app, Green backdrop for Mini Diary app, similarily in the 3rd row notice the green backdrop behind the MAIL app.... I need to change these backdrops. Thanks in advance. Appreciate your help.

  • Getting installed app size

    - by alex
    I'm trying to figure out how to get the size of an installed app. What's already failed: - new File('/data/app/some.apk') - reports incorrect size - PackageManager.getPackageSizeInfo(String packageName, IPackageStatsObserver observer) - is @hide and relies on some obscure IPackageStatsObserver for result so I can't call it via reflection.

  • how to save state of dynamically created editTexts

    - by user922531
    I'm stuck at how to save the state of my EditTexts on screen orientation. Currently if text is inputted into the EditTexts and the screen is orientated, the fields are wiped (as expected). I am already calling onSaveInstanceState and saving a String, but I have no clue on how to save the EditTexts which are created in code and then retrieve them and add them to the EditTexts when redrawing the activity. Snippet of my code: My main activity is as follows: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // get the multidim array b = getIntent().getBundleExtra("obj"); m = (Methods) b.getSerializable("Methods"); // method to draw the layout InitialiseUI(); // Restore UI state from the savedInstanceState. if (savedInstanceState != null) { String strValue = savedInstanceState.getString("light"); if (strValue != null) { FLight = strValue; } } try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** Called when the back button is pressed. */ @Override public void onResume() { super.onResume(); try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** saves data before leaving the screen */ @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("light", FLight); } /** called when exiting / leaving the screen */ @Override protected void onPause() { super.onPause(); Log.d(TAG, "onPause()"); if (mCamera != null) { mCamera.stopPreview(); mCamera.release(); mCamera = null; } } /* * set up the UI elements - add click listeners to buttons used in * onCreate() and onConfigurationChanged() * * Set the editTexts fields to show the previous readings as Hints */ public void InitialiseUI() { Log.d(TAG, "Start of InitialiseUI, Main activity"); // get a reference to the TableLayout final TableLayout myTLreads = (TableLayout) findViewById(R.id.myTLreads); // Create arrays to hold the TVs and ETs final TextView[] myTextViews = new TextView[m.getNoRows()]; // create an empty array; final EditText[] myEditTexts = new EditText[m.getNoRows()]; // create an empty array; for(int i =0; i<=m.getNoRows()-1;i++ ){ TableRow tr=new TableRow(this); tr.setLayoutParams(new LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); // create a new textview / editText final TextView rowTextView = new TextView(this); final EditText rowEditText = new EditText(this); // setWidth is needed otherwise my landscape layout is OFF rowEditText.setWidth(400); // this stops the keyboard taking up the whole screen in landscape layout rowEditText.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI); // add some padding to the right of the TV rowTextView.setPadding(0,0,10,0); // set colors to white rowTextView.setTextColor(Color.parseColor("#FFFFFF")); rowEditText.setTextColor(Color.parseColor("#FFFFFF")); // if readings already sent today set color to yellow if(m.getTransmit(i+1)==false){ rowEditText.setEnabled(false); rowEditText.setHintTextColor(Color.parseColor("#FFFF00")); } // set the text of the TV to the meter name rowTextView.setText(m.getMeterName(i+1)); // set the hint of the ET to the last submitted reading rowEditText.setHint(m.getLastReadString(i+1)); // add the textview to the linearlayout rowEditText.setInputType(InputType.TYPE_CLASS_PHONE);//InputType.TYPE_NUMBER_FLAG_DECIMAL); tr.addView(rowTextView); tr.addView(rowEditText); myTLreads.addView(tr); // add a reference to the textView myTextViews[i] = rowTextView; myEditTexts[i] = rowEditText; } final Button submit = (Button) findViewById(R.id.submitReadings); // add a click listener to the button try { submit.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Log.d(TAG, "Submit button clicked, Main activity"); preSubmitCheck(m.getAccNo(), m.getPostCode(), myEditTexts); // method to do HTML getting and sending } }); } catch (Exception e) { Log.d(TAG, "Exceptions (submit button)" + e.toString()); } }// end of InitialiseUI I don't need to do anything with these values until a button is clicked. Would it be easier if they were a ListView, i'm guessing I would still have the problem of saving them and retrieving them on rotation. If it helps I have an object m which is a string[][] I could temporarily somehow store them in

  • Java - 'continue' loop iteration after certain timeout period

    - by Matt
    Is there a way to exit ('continue;') a loop iteration after a certain timeout period? I have a loop that will run gathering data from the web and then use this data to make a calculation. The data become obsolete after about 1 to 2 seconds so if the loop iteration takes longer than 1 second then i want it to 'continue' to the next iteration. Sometimes gathering the data can take time but sometimes the calculation can take longer than 1 second so a HTTP timeout won't work for what i need. Also, while doing the calculation the thread i am using is blocked so i cannot check System.currentTimeMillis(); Is there a way to use another Thread to check the time and force the original for loop to continue.

  • Which type of data can be garbage collected when app is in background?

    - by Neoh
    Let's say I start from activity A - activity B. While in activity B I press home to exit. After a long time, gc may be called because other apps take higher priority. My question is, which of the following type of data will be garbage collected (I'm pretty sure static fields can be garbage collected any time but I'm not sure about these): i) fields that are declared final or static final ii) intent and its data that I passed from activity A to activity B iii) onSavedInstanceState when orientation is changed during the app running I ask this because I want to ensure that my app won't crash when I restore activity B from background after a long period.

  • Fragments keep going back to the default position when MapView is Zoomed In/Out

    - by hectichavana
    I have an activity with 3 fragments displayed, a MapActivity, a ListActivity, and a (normal) DetailsActivity. The ListActivity and DetailsActivity is placed over the MapActivity. There's a function to hide both ListActivity and DetailsActivity with an Animation, and onAnimationEnd() I set a new layout for the hidden Activity. The problem I'm facing is, everytime one of the ListActivity or DetailsActivity hidden (picture State 2), and then I pinch the screen on the MapActivity to zoom the map, it always goes back to the default view (picture State 1). The closed Activities are automatically opened again. Does anybody know how to prevent the hidden fragments from going to the first state again when I pinch the MapActivity? this is an example of the function how I hide the DetailsActivity(): public void hideDetailview() { final Animation close = AnimationUtils.loadAnimation(this, R.anim.close); close.setFillEnabled(true); close.setAnimationListener(closeDetailAnimationListener); fragment_detail.startAnimation(close); Toast.makeText(MainFragmentActivity.this,WWHApplication.getDrawer(), Toast.LENGTH_SHORT).show(); } private AnimationListener closeDetailAnimationListener = new AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationRepeat(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { int newLeft = -330; fragment_detail.layout(newLeft, fragment_detail.getTop(), newLeft + fragment_detail.getMeasuredWidth(), fragment_detail.getTop() + fragment_detail.getMeasuredHeight()); } };

  • Is it possible to import specific class from project propreties

    - by Alex
    I have 2 projects. First project need to include second. When I copy sources from second project to first I need to modify manually import path to R.java file. The problem is that I need to use SVN external link connection between this 2 projects, that is mean, one project (the bigger one) will take sources from another through svn and should be able to use it without any modifications. If I would be able to specify R.java file path anywhere in project properties it will resolve my problem by changing manually that path. Need to specify that package name of these 2 projects are different. Another solution to resolve this problem also would be accepted. Thank you.

  • Am I writing this right? [noob]

    - by Aaron
    private final int NUM_SOUND_FILES = 4; private Random rnd = new Random(4); private int mfile[] = new mfile[NUM_SOUND_FILES]; //the second mfile //reports error everytime mfile[0] = R.raw.sound1; mfile[1] = R.raw.sound2; mfile[2] = R.raw.sound3; mfile[3] = R.raw.sound4; int sndToPlay = rnd.nextInt(NUM_SOUND_FILES); I keep getting syntax errors no matter how I write it.

  • custom ListView --Null pointer exception

    - by raghs
    this code throws a Null pointer exception. It was thrown by getChildAt(i). The getCount() returns the number of items in listView. But getChildAt(i) returns only if item is present in current list view. For example in a scrollable list view assume that there are 20 items. The getCount() returns 20. But getChildAt(20) returns null. Because it doesnot fit in listview. How to solve this problem?? int i,j=object.getCount(); View v=getListView(); CheckBox chk=null; for(i=0;i<j;i++) { chk=((CheckBox)((ViewGroup) v).getChildAt(i).findViewById(R.id.checkBox1)); if(chk.isChecked()) { //download the contents to specific folder in sd card } }

  • i want to display this listview on scrolling

    - by Sasil
    I'm completely stumped on this one. I have three different lists that need to be displayed on the screen. I've tried using a ScrollView with a LinearLayout child, and putting my ListViews in the LinearView, but all of the ListViews lock to a fixed height with scroll bars. Using other kinds of Layouts means no scrolling.

  • Setting a ListView Divider in code

    - by deSelby
    One of my ListView's needs to be created in code. When I specify a ListView in xml, I can set a dividerHeight and assign a color to the divider. But apparently, in code a color is not acceptable nor is pointing to a resource id. Only a Drawable is acceptable - and I haven't gotten to that chapter yet. Can someone point me to an example of setting a ListView divider in code?

  • how to set footer image in this video screen?

    - by bala
    hi my problem is how to create footer image in this video screen while playing.... how to create this format. now i am give my description: • 1) Header image, a stretched background image. The location of this external image comes from the application xml; • 2) Footer image, a stretched background image. The location of this external image comes from the application xml; 2.a) the copyright, disclaimer and buy block, this block contains links to popup windows that contain a copyright and or disclaimer. And an option to buy the application for the advertisement less version. The content of this block is fed trough the application XML feed. The color of the text is fed by the application xml plus the popup links and texts itself; • 3) Carousel image, a stretched background image. The location of this external image comes from the application xml; 3.a) the carousel contains objects that can flow from right to left, possibly trough a animation (a soft break of the slide). The first object is centered in the middle of the carousel. This is the first element in the video feed. All the subsequent video object are added to the right of the centered object; 4) Total Video object, this object links to window two with the corresponding video of this object. This object is visually build out of the following sub parts:o 4.a) Thumb object (possible playing video thumb); 4.b) Reflection of the Thumb; 4.c) Textual Explanation of Thumb. 1) Video stream, this is the video stream coming from a external server streamed to the television (maybe up scaled) as 720p stream; 2) Advertisement, the type of advertisement shown overlaid on the video is based on previous settings in the video feed. This could mean that Admob, Adsense or a third party image plus URL could be shown. When the advertisement is selected trough navigation (it will highlight in a different color as a border around the advertisement. The color an thickness can be managed trough the application xml), when clicked a browser will open with the associated site (the application will be pushed to the background process, when the user is finished it will return to the app); 3) A back button, an image and navigational element. The location of the image comes from the application xml. The button is only shown when a cursor is moved (a button is pressed on the remote) it will highlight when selected and when pressed will forward the screen to the main window. When the main window is opened the video will be removed from cache and memory and cannot be start from the point it was exited. please give me your idea....

  • Sync between local service with a thread and an activity

    - by Henrik
    Hello all, I'm trying to think of a way on how to sync in between a local service and the main activity. The local service has, A thread with a socket connection that could receive data at any time. A list/array with data. At any time the socket could receive data and add it to the list. The activity needs to display this data. So when the activity starts up it needs to attach or start the local service and fetch the list. It also needs to be notified if the list is updated. I think I would need to sync my list somehow so the local service does not add a new entry to it while the activity fetches the list when connecting to the service. Any ideas? Thanks.

  • Overfocus in GridView

    - by chuck258
    I'm trying to implement a GridView that Focuses the next Item and "Overscrolls at the End of a List. E.g. 1 2 3 4 5 6 7 8 9 I want to scroll 1 2 3 4 5 6 ... just by pressing the right Key. Right now I can only Scroll 1 2 3 and then it stops and I have to scroll with the down Key. I already tried to set the focusViews in code (In the getView() method of my ArrayList Adapter, that fills the GridView) view.setId(position); view.setNextFocusLeftId(position-1); view.setNextFocusRightId(position+1); But that doesn't work. I found the boolean *Scroll(int direction) Methods on grepcode But theese are Package Local and I can't overwrite them. Any suggestions on how to solve this. Can I use another View and get the same Layout as a Gridview? I also set a OnFocusChangeListener to see what happens with no reaction. Edit: I just added this to my MainActivity, but now it seems to onKeyDown only get called when the GridView doesn't handle the KeyEvent (If the Last Item in a row is selected). @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { case KeyEvent.KEYCODE_DPAD_LEFT: if (focusedView > 0) { mContainer.setSelection(--focusedView); Log.v("TEST", focusedView+""); } return true; case KeyEvent.KEYCODE_DPAD_RIGHT: if (focusedView < mAdapter.getCount() - 1) { mContainer.setSelection(++focusedView); Log.v("TEST", focusedView+""); } return true; } return super.onKeyDown(keyCode, event); } Edit 2: This is so f***ing stupid but works so damn fine :D @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { case KeyEvent.KEYCODE_DPAD_LEFT: mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_UP, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_UP)); mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_RIGHT)); mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_RIGHT)); return true; case KeyEvent.KEYCODE_DPAD_RIGHT: mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_DOWN, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_DOWN)); mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT)); mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT)); return true; } return super.onKeyDown(keyCode, event); } I really don't want to post this as Answer, and I really don't want to have to use this Code because it is such a stupid workaround ;TLDR: Help still needed
