Android SeekBar set progress value

Question

I want the SeekBar progress to change whenever I click a button. Using setProgress() works only for initial value. It throws an error if I use it after some changes.

Answer 1

Perhaps you should try to use a handler? I use this in an app of mine and works fine.

1) When creating your SeekBar:

// ... seekBarHandler = new Handler(); // must be created in the same thread that created the SeekBar seekBar = (SeekBar) findViewById(R.id.my_seekbar); // you should define max in xml, but if you need to do this by code, you must set max as 0 and then your desired value. this is because a bug in SeekBar (issue 12945) (don't really checked if it was corrected) seekBar.setMax(0); seekBar.setMax(max); seekBar.setProgress(progress); // ... 

2) When your button is clicked

// ... seekBarHandler.post(new Runnable() {     @Override     public void run() {         if (seekBar != null) {             seekBar.setMax(0);             seekBar.setMax(max);             seekBar.setProgress(newProgress);         }     } }); // ...
