        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {}

    });

回答1:

setLeft() is for positioning. A SeekBar always starts with a value of 0 and rises to the maximum (100 by default, overridden via setMax()).

To get a 3-11 range, call setMax(8), then add 3 to the result of getProgress() when you retrieve the current value.

回答2:

To move your SeekBar in increments you test for fromUser and set the progress to the value you want. In this example the progress indicator will "snap" to the nearest 10 as you move it.

@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)
{
  // round progress up or down to the nearest 10
  int roundedProgress = (int) (Math.rint((double) progress / 10) * 10);
  if (fromUser)
  {
    seekBar.setProgress(roundedProgress);
  }
}
