Hard to say what you really want from the snippets of information and code you provided. Generally speaking you normally only call setContent() to setup your screen from your activity's onCreate() method, not when some state changes that needs reflection on the UI. When you have state changes you need to find the GUI element that you want to change with findViewById() an call setText() (or whatever) on it directly. It will redraw itself then.
And as Romain said, don't do any sleeps or other long running stuff on the UI thread. This way you will block, which will in turn lead to unresponsiveness, e.g. a press of the menu key or a tap on the screen will not be dispatched until the UI thread is freed up again. Provide a working, simple, short sample just demoing one concept you are trying to understand. And it would be easier to help you. What helped me better understanding this basic concepts was doing the samples. http://developer.android.com/guide/tutorials/notepad/index.html On Thu, May 14, 2009 at 8:37 AM, Sukitha Udugamasooriya <[email protected]>wrote: > > Hi geniuses, > > I have few buttons on the content.
