Question

I have an activity with ListView that has:

android:theme="@android:style/Theme.Dialog"

in Manifest.
When I open it and when it has only one line in ListView, the window that opens is very small.
How do I make the window take the whole screen?

Answer 1

Use this in your onCreate method of the Activity to make it full screen.

   @Override
protected void onCreate(Bundle arg0) {
    super.onCreate(arg0);
    setContentView(R.layout.myxml);

    LayoutParams params = getWindow().getAttributes(); 
            params.height = LayoutParams.MATCH_PARENT;
            params.width  = LayoutParams.MATCH_PARENT;
           getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
   }
