setPositiveButton() is for setting the button text and listener. To use findViewById, you need to set your own custom layout, but this won't work with AlertDialog.Builder (iirc), you need to use the Dialog class. Here is some code I use for this in my application:
mDialog = new Dialog(this); mDialog.setCancelable(true); mDialog.setContentView(R.layout.dialoginput); //set the custom layout mBtn_DialogOK = (Button) mDialog.findViewById(R.id.btn_ok); //From our custom layout mBtn_DialogOK.setTag(BUTTON_OK_ID); mBtn_DialogOK.setOnClickListener(this); Also, findViewById is for R.id.<id of view>, not for Strings.
