How to get the AlertDialog title?

Question

I tried to get the message and the following line of code works:

TextView dialogMessage = (TextView)dialogObject.findViewById(android.R.id.message);

But when I try to get the title using the following line it returns null

TextView dialogTitle = (TextView)dialogObject.findViewById(android.R.id.tittle);

Answer 1

I checked up the code of the AlertDialog. Internally they use R.id.alertTitle to initialize the AlertDialog title's TextView. You can use getIdentifier to retrieve it:

int titleId = getResources().getIdentifier( "alertTitle", "id", "android" );
if (titleId > 0) {
   TextView dialogTitle = (TextView) dialogObject.findViewById(titleId);
   if (dialogTitle != null) {

   }
}

Edit: for AppCompat, the third argument of getIdentifier should be the package name of your app. You can retrieve the latter with context.getPackageName()

Answer 2

I know the question mentions AlertDialog, but if you came here through a Google search and looking for the answer for a DialogFragment:

getDialog().findViewById(android.R.id.title))
