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;
}
});
###
Have you tried disabling the view?

Ideally you shouldn’t be doing this, as this is going to confuse the user. My suggestion is rethink your approach.
###
Set one class level variable
private boolean blockSeekBar = false;
after that set blockSeekBar variable as per your requirement and use in app.
seekBar.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
return blockSeekbar;
}
});
setEnabled(true/false) also choice but there view is not showing good so thats why above code is perfectly working.

int lastProgress=0;

Keep track of the last progress when the Seekbar.OnSeekbarChangeListener is fired.
private SeekBar.OnSeekBarChangeListener mOnSeekbarChangeListener = new SeekBar.OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar seekbar, int progress, boolean fromUser) { if (fromUser) { if (true) { seekbar.setProgress(lastProgress); } else { seekbar.setProgress(progress); } } } @Override public void onStartTrackingTouch(SeekBar seekBar) { lastProgress = seekBar.getProgress(); } @Override public void onStopTrackingTouch(SeekBar seekBar) { } };
