If the user moves B,C or D I calculate the average of the three and setProgress of A to the average. That was the easy part . What I would like to do is animate the progress bar A such that it does not jump in one shot (for eg from 25-75 ). What are the recommended ways to animate A? I got a simple animation up but I am calling a TimerTask every 50ms to increment or decrement A by a unit value till I reach the required position. But its not very efficient. Note: I have a

I want to create android custom SeekBar having thumb with text inside it to show current seek position. Here is my code: SeekBar sb; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.custom_seek_bar_activity); sb = (SeekBar)findViewById(R.id.slider); sb.setMax(100); sb.setProgress(10); BitmapDrawable bd = writeOnDrawable(R.drawable.star2, Double.toString(50)); sb.setThumb(bd); sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){ @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

how can I get the values ​​from 0.0 to 2.0 with a seekbar ? values ​​should go in steps of 0.5 ( 0.0 , 0.5 , 1.0, 1.5, 2.0) can someone help me? SeekBar extends ProgressBar. ProgressBar has a method public void setMax(int max) Since it only accepts int you'll have to do some conversion from an int value to get the float that you are after. Something like this should do the trick: mSeekBar.setMax(4); //max = 4 so the possible values are 0,1,2,3,4 seekbar.setOnSeekBarChangeListener( new OnSeekBarChangeListener(){ public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) { //

does anybody know, how to set a seekBar to a specific value or just a click on that view on Espresso UI Testing ? I just get an exception: Error performing 'single click' on view with id... onView(withId(R.id.FilterPriceMax)).perform(click()); I use a swipe-action to perform an actual swipe on the SeekBar . This makes sure the callback method ( SeekBar.OnSeekBarChangeListener. onProgressChanged ) is called with fromUser set to true. It is also more in the line of click testing. public static ViewAction scrubSeekBarAction(int progress) { return actionWithAssertions(new GeneralSwipeAction( Swipe

Basically, I need to detect when the progress changes in the SeekBar and draw a text view on top of the thumb indicating the progress value. I do this by implementing a OnSeekBarChangeListener and on the public void onProgressChanged(SeekBar seekBar, int progress, boolean b) method, I call Rect thumbRect = seekBar.getThumb().getBounds(); to determine where the thumb is positioned. This works perfectly fine, but apparently getThumb() is only available in API level 16+ (Android 4.1), causing a NoSuchMethodError on earlier versions. Any idea how to work around this issue? I was able to use my own

I want to block the dragging of a seekbar if a value is true. Is this even possible? I use a seekbar as a switch. If my seekbar value is 0, and I press the button action A started. If my seekbar value is 1 and I press the button action B is started. I want to prevent that If action A or B is running the seekbar is dragged to another position. How can I achieve this? You should set your own onTouchListener and just return true. seekBar.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View view, MotionEvent motionEvent) { return true; } }); JoxTraex Have you tried
