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.
