Changing font size into an AlertDialog

by

You can actually get access to the message’s TextView pretty easily, and then change it’s size. I tested with a bigger size, but you could use whatever size you want. The text will scroll nicely as it already does. The view’s id is android.R.id.message

    AlertDialog dialog = new AlertDialog.Builder(this).setMessage("Hello world").show();
    TextView textView = (TextView) dialog.findViewById(android.R.id.message);
    textView.setTextSize(40);

This is probably a cleaner solution, though I’m not sure if there’s a risk that the TextView could be null or not.
