Answer 1

use tablelayout an then use tablerowlayout. and put your checkboxes.

Answer 2

android:layout_gravity is not relevant in a LinearLayout. It is meant for a FrameLayout. It means "what should be my gravity in relation to my (FrameLayout) father". android:gravity on the other hand means "what is the gravity inside me" and it applies to different views differently (like in a TextView it will align the text according to the gravity).

I think you could probably throw out half of the layouts you are using to display views (it's kind of confusing and hard to read) by simplifying your layout scheme and use just using a RelativeLayout for alignment issues (align to parent or to other views) and LinearLayout for grouping vertical and horizontal groups.

Answer 3

try the following

android:layout_gravity="right"
android:gravity="right"
