how to limit seekbar

Question

I'd like to set max and minimum limits of SeekBar to 50 and 20 respectively.

SeekBar has a direct option top provide max value, but how to set its minimum value to 20 rather than 0?

Answer 1

In SeekBar you can set only max value.

<SeekBar android:id="@+id/SeekBar01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:max="50"/> 

And, You cannot directly set the minimum value to the seekbar.

 SeekBar mSeekbar = (SeekBar) findViewById(R.id.SeekBar01);      mSeekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener()     {        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser)        {             length_edit.setText(Integer.toString(progress + 20));        }        public void onStartTrackingTouch(SeekBar seekBar) {}        public void onStopTrackingTouch(SeekBar seekBar) {}     }); 

As you see min progress you can sum with min which I would like - in your case 20.
