private SeekBar.OnSeekBarChangeListener customSeekBarListener = new SeekBar.OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
//currentCustomPercent = seekBar.getProgress();
customTipTextView.setText(String.valueOf(seekBar.getProgress()));
//updateCustom();
}
};
То есть при прокрутке SeekBar у меня должно меняться значение в TextView, а оно никак не меняется, что не так?
P.S: Я новичок в программировании под Android
