The AlertDialog class takes care of automatically setting * {@link android.view.WindowManager.LayoutParams#FLAG_ALT_FOCUSABLE_IM * android.view.WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM} for you based on whether * any views in the dialog return true from {@link View#onCheckIsTextEditor() * View.onCheckIsTextEditor()}. Generally you want this set for a Dialog * without text editors, so that it will be placed on top of the current * input method UI. You can modify this behavior by forcing the flag to your * desired mode after calling {@link #onCreate}. * *
