Android SeekBar thumb gets clipped/cut off

You should be able to fix this by setting paddingLeft and paddingRight on your SeekBar to half the thumb width (remember to use density-independent units). You can also control the space allowed at the edges for a seek bar's thumb by calling setThumbOffset.

For default SeekBar I used these settings and it works fine:

android:paddingLeft="6dp"
android:paddingRight="6dp"

android:thumbOffset="8dp"

I ran into this issue myself, and I believe the "correct" decision would be to modify android:thumbOffset as the default style for a SeekBar sets it to 8px.
