Question

I got a problem with a really, really simple AlertDialog that creates my About dialog with three choices. Have a look at how it looks like on an emulator, my HTC Sensation and a Galaxy S2:

The dialog is created by this (pseudo) code:

builder.setPositiveButton("OK", null);
builder.setNeutralButton("Disclaimer", [...]);
builder.setNegativeButton("Jetzt zum Market", [...]);

It is so simple, I never thought about maximum text lengths differing so much on different devices! Plus: I think Samsung’s tearing apart of “Disclaimer” is such a mess, not to talk about the whole word “Market” missing.

How am I supposed to create a simple AlertDialog when this already is a problem?
Any clues? Think of a device that sets such a large font that even “Cancel” does not fit any more! sigh How can I prevent such things?

Thanks for advices!!

The answer from Drew DeNardo is almost correct.

The myDialog.getButton(BUTTON_POSITIVE) is returning null because it was not been created.

You need to override onShow:

final AlertDialog alert= builder.create();

alert.setOnShowListener(new DialogInterface.OnShowListener() {

    @Override
    public void onShow(DialogInterface dialog) {

        float textSize = 15.0f;

        Button positive = alert.getButton(AlertDialog.BUTTON_POSITIVE);
        positive.setTextSize(TypedValue.COMPLEX_UNIT_DIP, textSize);

        Button neutral = alert.getButton(AlertDialog.BUTTON_NEUTRAL);
        neutral.setTextSize(TypedValue.COMPLEX_UNIT_DIP, textSize);

        Button negative = alert.getButton(AlertDialog.BUTTON_NEGATIVE);
        negative.setTextSize(TypedValue.COMPLEX_UNIT_DIP, textSize);
    }
});
