How can I disable all views inside the layout?

Question

For example I have:

Answer 1

this one is recursive for ViewGroups

private void disableEnableControls(boolean enable, ViewGroup vg){
    for (int i = 0; i < vg.getChildCount(); i++){
       View child = vg.getChildAt(i);
       child.setEnabled(enable);
       if (child instanceof ViewGroup){ 
          disableEnableControls(enable, (ViewGroup)child);
       }
    }
}
