Question

In my app I want to have a button that if the user clicks it
than a new layout is opened within the current (acually the main) layout.
the new layout should not fill all of the screen and parts of the previous layout
should be grayed out.
Any ideas on how to do this ?

Answer 1

You can show a hidden layout within your button’s onClick event by calling

view.setVisibility(View.VISIBLE) 

You can also fade out view elements or whole views with

view.setAlpha(75); 
view.setBackgroundColor(Color.GRAY);

Note that “view” in the first example is your layout element.. LinearLayout, RelativeLayout, etc. and in the 2nd example, “view” is the element(s) you’re trying to gray out.
