The AlertDialog class takes care of automatically setting * {@link WindowManager.LayoutParams#FLAG_ALT_FOCUSABLE_IM * WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM} for you based on whether * any views in the dialog return true from {@link View#onCheckIsTextEditor() * View.onCheckIsTextEditor()}.

You can modify this behavior by forcing the flag to your * desired mode after calling {@link #onCreate}. * *
