  • How can I vary the height of some keys within a row?

    - by ea
    I'm creating a custom keyboard layout. The SDK allows changing the width of keys in a row (as in ThickButtons), but ideally I'd like to be able to vary both the height and width of keys within a row (and still have the keys occupy all the available space.) Another way of looking at this is that I want to allow some keys to be in more than one contiguous row. Any ideas would help. Thank you.

  • Padding List Items?

    - by Lee Olayvar
    I have a list where i basically need a hierarchy of items. Any children of an item would be padded slightly, as to easily distinguish their parent item. How could this be achieved? Note that i could, if needed, make each parent show no children, and then when the parent is clicked, a new list containing all of it's children is loaded. This however requires more clicking to display information than i would prefer. Also, the items themselves will contain graphics and whatnot (to show a drag'n'drop button, etc), so it would be best if it visually appeared as if the item itself had a margin, rather than the contents of the item being padded. Thanks to any replies!

  • Why do the usable sizes differ

    - by Raigex
    Again, dont really know how to phrase the question so I will explain. I have a video recorder application. I open my camera with cameraRecorder = Camera.open(1); //(this is the front facing camera) And get the camera parameters and all supported preview sizes CameraParameters tmpParams = cameraRecorder.getParameters(); List<Camera.Size> tmpList = tmpParams.getSupportedPreviewSizes(); one of the preview sizes on the Galaxy Tab 10.1 running ICS (4.0.4) is 800x600 but when I try to set the Video size in my media Player mediaRecorder.setVideoSize(800,600); I get this error: 12-19 17:27:55.035: E/CameraSource(110): Video dimension (800x600) is unsupported 12-19 17:27:55.035: E/StagefrightRecorder(110): cameraSource do not init 12-19 17:27:55.035: E/StagefrightRecorder(110): setupCameraSource failed. (-19) 12-19 17:27:55.035: E/StagefrightRecorder(110): setupMediaSource is failed. (-19) 12-19 17:27:55.035: E/StagefrightRecorder(110): setupMPEG4Recording is failed. (-19) 12-19 17:27:55.035: E/MediaRecorder(30119): start failed: -19 Does anyone know why this discrepancy might exist (I know one of the supported record sizes is 1280x720 but that is too big for me).

  • Exchange ActiveSync is not working with Android's 'verify certificate' setting, what do I need to do to make them work together?

    - by Yannone
    All other methods of Activesync and web access to my Exchange server are working fine with no errors or issues, but when we attempt to configure Android phones for the server, it will only work with 'verify certificate' checked off. Ideally, I'd like my users to be able to use the default configuration, which includes the 'Verify Certificate' option. My primary question is: 'What does Verify Certificate do?', as I imagine if I knew that, I might have some idea why it isn't working.

  • How to use SQLiteOpenHelper without or less restrictive use of Context?

    - by Pentium10
    If you extend SQLiteOpenHelper, for the Constructor you have to use a Context. I am wondering if there is a way to leave this out, and be able to work with database tables without a Context. Or at least be least restrictive, I mean a way of project/class structure that will make history the several context passings I have to do now. As it is my application has several level of classes, chained in each other, and there are a few that connects to the database, but have no whatsoever influence on the interface, so they don't actually need the Context. Are you creating your classes in the way that you pass each time a Context to them? If not, how you do, how you reuse a Context in a short class?

  • table row long press

    - by adoo42
    I have a table which is built dynamically based on how much data is present, if at all. I want to be able to long press anywhere on a the table row to be able to get some options to delete or edit etc. Is this possible? Remember I need to do all this without setting any XML as its dynamically built. Is this relevant to what I want to achieve? ` @override public boolean onKeyLongPress(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { // do your stuff here return true; } return super.onKeyLongPress(keyCode, event); } ` any advice is appreciated.

  • Elegant solution to retrieve custom date and time?

    - by kefs
    I am currently using a date and time picker to retrieve a user-submitted date and time, and then I set a control's text to the date and time selected. I am using the following code: new DatePickerDialog(newlog3.this, d, calDT.get(Calendar.YEAR), calDT.get(Calendar.MONTH), calDT.get(Calendar.DAY_OF_MONTH)).show(); new TimePickerDialog(newlog3.this, t, calDT.get(Calendar.HOUR_OF_DAY), calDT.get(Calendar.MINUTE), true).show(); optCustom.setText(fmtDT.format(calDT.getTime())); Now, while the above code block does bring up the date and time widgets and sets the text, the code block is being executed in full before the user can select the date.. ie: It brings up the date box first, then the time box over that, and then updates the text, all without any user interaction. I would like the date widget to wait to execute the time selector until the date selection is done, and i would like the settext to execute only after the time widget is done. How is this possible? Or is there is a more elegant solution that is escaping me? Edit: This is the code for DatePickerDialog/TimePickerDialog which is located within the class: DatePickerDialog.OnDateSetListener d=new DatePickerDialog.OnDateSetListener() { public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { calDT.set(Calendar.YEAR, year); calDT.set(Calendar.MONTH, monthOfYear); calDT.set(Calendar.DAY_OF_MONTH, dayOfMonth); //updateLabel(); } }; TimePickerDialog.OnTimeSetListener t=new TimePickerDialog.OnTimeSetListener() { public void onTimeSet(TimePicker view, int hourOfDay, int minute) { calDT.set(Calendar.HOUR_OF_DAY, hourOfDay); calDT.set(Calendar.MINUTE, minute); //updateLabel(); } }; Thanks in advance

  • Unable to add multiple textviews into linearLayout within a loop

    - by Adam
    for(int i=0;i<object.size();i++){ FeaturedSingleEvent event = (FeaturedSingleEvent) object.get(i); images.add(event.getImage()); LinearLayout info = new LinearLayout(this); info.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); TextView title = new TextView(this); title.setText(event.getTitle()); title.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(title); TextView by = new TextView(this); by.setText(event.getBy() + " " + event.getBy_name()); by.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(by); TextView summary = new TextView(this); summary.setText(event.getSummary()); summary.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(summary); layout.addView(info); if(i == 0){ info.setVisibility(View.VISIBLE); }else{ info.setVisibility(View.GONE); } } I'm attempting to have multiple LinearLayouts, only one being visible at a time, to create a slideshow. In a for loop, I create the layouts with their textViews, and set only the first one to be visible. The problem is that only one TextView seems to be displaying, ie. if everything but summary is deleted, then summary will display. As of right now, only title will display, because i'm assuming it's the first one. I'm most likely doing it wrong, so any help would be appreciated.

  • How to avoid the linebreak inside a word (Static Layout

    - by Addev
    I'm trying to make a text as big as I can making it fit a Rect. basically I use a StaticLayout for pre-calculate the text size and make it fit the Rect's height: // Since the width is fixed for the StaticLayout it should only fit the height while (currentHeight>Rect.getHeight()){ size-=2; } textPaint.setTextSize(size); The problem is that if the Rect is very high, the exit condition is reached but breaking the words (see the capture). Is there a way for avoid this? Goal: Actual: Current code: textSize=MAX_TEXT_SIZE do { if (textSize < mMinTextSize) { Log.i(TAG, "Min reached"); textSize = mMinTextSize; textPaint.setTextSize(textSize); fits = true; } else { textPaint.setTextSize(textSize); StaticLayout layout = new StaticLayout(text, textPaint, targetWidth, Alignment.ALIGN_NORMAL, 1.0, 0, true); layout.draw(canvas); float heightRatio= (float) layout.getHeight() / (float) targetHeight; boolean fitsHeight = heightRatio<= 1f; if (fitsHeight) { fits = true; } else { textSize -= 2; } } Log.i(TAG, "textSize=" + textSize + " fits=" + fits); } while (!fits); thanks

  • setImageViewResource Sometimes loads image and sometimes it doesn't.

    - by Niv
    Hi All, I'm writing a simple widget which has an imageview widget that is supposed to load an image dynamically. To do this, I'm starting a service in the onUpdate method of the service. I validated that the service is running, however, the image is loaded only once every 10 times. Here is the code: (In the Original extends AppWidgetProvider) @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Log.d(LOG_TAG, "onUpdate(): Starting Service..1"); context.startService(new Intent(context, UpdateService.class)); } (The service:) @Override public void onStart(Intent intent, int startId) { Log.d(LOG_TAG, "(OnStart) In On Start..!"); AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this); int[] appWidgetIds = appWidgetManager.getAppWidgetIds(new ComponentName(this, Original.class)); for (int appWidgetId : appWidgetIds) { RemoteViews remoteView = new RemoteViews(this.getPackageName(), R.layout.widget); remoteView.setImageViewResource(R.id.widgetImage, R.drawable.let02); remoteView.setTextViewText(R.id.widget_textview_month, "aaa"); Log.d(LOG_TAG, "(OnUpdate) Set All Fields!"); appWidgetManager.updateAppWidget(appWidgetId, remoteView); } //super.onStart(intent, startId); return; }

  • Click Listener not invoked within ListFragment

    - by membersound
    I'm extending a SherlockListFragment, but it should not matter as my question seems to be more general related to Fragments. Now, I implement a simple click listener for my list, but it does not get called. public class MyListFragment extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.list, container, false); v.setOnClickListener(new OnClickListener() { public void onClick(View view) { Log.i("debug", "single click"); } }); return v; } } Is anything wrong with this? //Solution: listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.i("debug", "single click"); } });

  • How to implement context menu on key press instead of long click/tap

    - by takyon
    I have a ListActivity and I want to implement context menu for each of the list elements. I know that the common way to do this is to show the context menu on long click/tap. I want to know if there is a way to show the context menu for each element on a key press(preferably the menu key). To rephrase my question, how can I trigger the context menu and not the options menu by pressing the menu key(or any other key).

  • Need help getting buttons to work...

    - by Mike Droid
    I am trying to get my first button to update a display number in my view when clicked. This view will have several buttons and "outputs" displayed. After reading examples and Q's here, I finally put something together that runs, but my first button is still not working; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.ship_layout); mSwitcher = (TextSwitcher) findViewById(R.id.eng_val); } private TextSwitcher mSwitcher; // Will be connected with the buttons via XML void onClick(View v){ switch (v.getId()) { case R.id.engplus: engcounter++; updateCounter(); break; case R.id.engneg: engcounter--; updateCounter(); break; } } private void updateCounter() { mSwitcher.setText(String.valueOf(engcounter)); } The .xml for this button is; <TextSwitcher android:id="@+id/eng_val" android:visibility="visible" android:paddingTop="9px" android:paddingLeft="50px" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/build" android:layout_toRightOf="@+id/engeq" android:textColor="#DD00ff00" android:textSize="24sp"/> This is within a Relative Layout that appears otherwise OK. When I had set the view to have a TextView with the number set as a string , the number displayed, but I could not figure out how to update the text with a numerical field. That may be my real problem. I have gone through many examples generally referenced from the dev. site (UI, Common Tasks, various samples), and I am still not seeing the connection here... Again, this is simply a try at getting variables to respond to buttons and update on the view. So, a few Q's for anyone that can help; 1) Is there any easier way of doing this (ie. send numerical value to View) ? 2) Why isn't my TextSwitcher displaying the number? 3) Should I be using a TextSwitcher here? 4) Any examples of this you can point me to?

  • Disable update on battery percentage

    - by Kris B
    I have a service that performs background updates. I want to give the user the the option to disable the updates when their battery percentage reaches a certain level. From my research, I'm going to use a receiver in the onCreate method of my Service class, eg: public class MainService extends Service { @Override public void onCreate() { this.registerReceiver(this.BatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED)); } private BroadcastReceiver BatInfoReceiver = new BroadcastReceiver(){ @Override public void onReceive(Context arg0, Intent intent) { int level = intent.getIntExtra("level", 0); } }; } I'm assuming the best practice is to leave the service running and check the battery level in the service and not perform the CPU intensive code based on the percentage? I don't actually stop the service itself and start it up again, based on the battery percentage?
