I need to use perticular image as the theme f开发者_StackOverflowor my most of the activities in my application... please help me how to do this..
Basic idea is to define and apply the custom style of your Activities in Res files. Tutorial here.
if your using XML display there is a field background
@drawable/custom_dialog_background
or
android:background in the XML anchors
setBackgroundResource(int) in your code
