Android seekbar how to block dragging / disable it for short time

问题

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?

回答1:

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;
            }
        });

回答2:

Have you tried disabling the view?

Ref: http://developer.android.com/reference/android/view/View.html#setEnabled(boolean)

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) {

}
};
