Answer 1

The LinearLayout before the CheckBox has its height set to MATCH_PARENT(and it fills all the parent’s height) and the parent LinearLayout of both has the orientation set to vertical so the CheckBox is pushed out of the screen.

Set the height of the LinearLayout containing the SeekBar to WRAP_CONTENT for example.
