You have to visibility gone of Relative layout.
NumeroPreventivi.setVisibility(View.GONE);
have you visibility gone or invisible of Relative Layout?because if you doing visibility gone of layout then its work perfectly and if you are doing visibility invisible then this layout existence true. i mean this layout take area of layout.
at run time you have to change weight sum of layouts.

Relative layout is shifing when progress bar running

I have login layout,when progress bar executes the layout shifts, This my xml code please check my code.And help me to rseolve.

How to center relative layout with its text and images?

I have RelativeLayout which has other elements such as imageview, textview inside it. When i run the app with small screen size (Galaxy S2) it is displayed as image 1. But when it runs on a larger screen (Nexus 7) it is displayed as in image 2. I do not want to enlarge the image for larger screens and i want it to keep certain sizes i set (see .xml). But how i can make it appears at the center on large screens (as in image 3).
Thank you for suggestions.

if you give match_parent means it'll fill the parent layout full so give wrap_content

android:layout_height="40dp"
android:background="#drawable/custom_title"
android:gravity="center_vertical" >
