There is no method, why don't you want to use `onProgressChanged`? It is the way to do it — Alberto Méndez, Nov 24 '16 at 13:05
add view on top of the seekbar and set it to clickable=true also use linearlayout to get the 20% — zombie, Nov 24 '16 at 13:06
Alberto Méndez can you provide me example if you know it in the fly ... — Nikola Lukic, Nov 24 '16 at 13:10
@zombie If I'm not wrong that wouldn't't work because if you drag and move Android keeps the focus in the Seekbar so the view click wouldn't be reached. — Alberto Méndez, Nov 24 '16 at 13:25

You can do it with onProgressChanged with a very basic calculations. If the min value is 0 and max value is 200 and we want to limit the first and last 20%. In the onProgressChanged method you just:

// I think this two variables should be out of the method
int limit = ((20 * 200) / 100);
int maxValue = seekBar.getMax();
if(seekBar.getProgress() >= (maxValue - limit)){
    seekBar.setProgress(maxValue);
}else if(seekBar.getProgress() <= limit){
    seekBar.setProgress(limit);
}

This has been done on the fly, it isn't tested and probably there is something wrong, but that is the idea

only need to remove minValue no need at all . in line : seekBar.setProgress(minValue); must be seekBar.setProgress(limit); – Nikola Lukic Nov 24 '16 at 13:25
Yes, you are right, and the same to the `else if ` condition, if i'm not wrong – Alberto Méndez Nov 24 '16 at 13:26

as mentioned in the answer here regarding

You can't define the minimum value. It is 0.

If you want to set maximum value you can do it

by xml

<SeekBar
    android:id="@+id/seekBar1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:max="your_max_value"/>

using java

seekBar = (SeekBar)findViewById(R.id.seekbar_id);
seekBar.setMax(your_max_value);
