If I understood question correctly, you can use library like this https://github.com/bozapro/circular-slider-range . To actually update some TextView inside clock circle you can use something like:

((CrystalRangeSeekbar) findViewById(R.id.range_slider)).setOnRangeSeekbarChangeListener(new OnRangeSeekbarChangeListener() {
            @Override
            public void valueChanged(Number minValue, Number maxValue) {
                //Your code to change TextViews here
            }
        });
