private static void applyListener(View child, OnClickListener listener) { if (child == null) return; if (child instanceof ViewGroup) { applyListener((ViewGroup) child, listener); } else if (child != null) { if(child.getId() == R.id.phoneEnd) { child.setOnClickListener(listener); } } } private static void applyListener(ViewGroup parent, OnClickListener listener) { for (int i = 0; i < parent.getChildCount(); i++) { View child = parent.getChildAt(i); if (child instanceof ViewGroup) { applyListener((ViewGroup) child, listener); } else { applyListener(child, listener); } } } |
Use applyListener(rootView, yourOnClickListener);
