Android :: Get Focus To GridView First Image?

Iam writing GridView by using BaseAdapter with 2 columns.Each column with One Image and Text.It works smoothly.I had given focus by using below code in onConfig...

public void onConfigurationChanged(Configuration newConfig) {
gridview.requestFocusFromTouch();
gridview.setSelection(0);
}

It works when my view configuration changes.But Same doesn't work in onCreate() method.I used below all methods in onCreate() but my view doesn;t get focus.How to give focus for the first image when running my application.I want focus on first image when view inflates on the device.Please give me guidance?................
