Answer 2

for your layout set

android:background="#00000000"

00 - Red

00 - Green 00 - Blue 00 - Opacity/Alpha....to specify transparency

for eg. :- #FF000050 will give you red color with 50% transparency

Answer 3

you can also set it in your java file like this:

 view.setBackgroundColor(Color.TRANSPARENT);

Answer 4

Try this:

android:background="@null"

Answer 5

Well, since you said you have an activity in the background, you should be using a fragment for this. If you're using a fragment, just set thr framelayout to transparent background, or don't set it at all, I think this should work as well, your fragment would be on top of the other layout.

If you use

getSupportFragmentManager().beginTransaction()
            .add(R.id.fragment_container, fragment).commit();

Then it just adds it on top of the previous one, doesn't replace it like .replace() does. If you want an activity to be on top of another activity, that is not possible, as there can be only one activity alive at one time.
