Cannot resolve symbol 'OnSeekBarChangeListener'

I'm trying to create a SeekBar listener, but for some reason the following:

final SeekBar birthdaySlider = (SeekBar) findViewById(R.id.birthdaySlider);

birthdaySlider.setOnSeekBarChangeListener(new birthdaySlider.OnSeekBarChangeListener() {});

Returns the error:

Cannot resolve symbol 'OnSeekBarChangeListener'

Solution

  • Correct way to do :

    final SeekBar birthdaySlider = (SeekBar) findViewById(R.id.birthdaySlider);

birthdaySlider.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
});

    Tip: In Android Studio if you press ctrl+space keys, you will see autocomplete menu, which includes possible methods.
