One OnClickHandler for multiple Buttons

Question

I find myself doing things like this all the time:

    Button button1 = (Button) findViewById(R.id.button1);
    Button button2 = (Button) findViewById(R.id.         


        

Answer 1

I think in case, when your buttons are not in Activity but in FragmentDialog, etc., this can help

Context mContext = getActivity().getBaseContext();
mRes = mContext.getResources();
String[] idOfButtons = { "button1", "button2", "button3"};
for (int pos = 0; pos < idOfButtons.length; pos++) {
   Integer btnId = mRes.getIdentifier(idOfButtons[pos], "id",(getActivity()).getBaseContext().getPackageName());
    ImageButton ib = (ImageButton) v.findViewById(btnId);
    ib.setOnClickListener(this.onClickNum);
}
