I know this is an old post, but I did something like this:

<LinearLayout
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:padding="16dp"
    android:id="@+id/XXXXXXXXXXXX"
    android:orientation="horizontal">
    <ImageView
        android:src="@drawable/XXXXXXXXXXXX"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:scaleType="centerInside"
        android:id="@+id/XXXXXXXXXXXXXXXX"/>
    <TextView
        android:id="@+id/XXXXXXXXXXXXXX"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="XXXXXXX"
        android:layout_gravity="center"/>
</LinearLayout>

If you don't want to deal with Bitmap.createScaledBitmap then it seems to me that the best way to do it is to create your own component. You can extend RelativeLayout and put ImageView into it, for example.

I don't hink you can from xml. There's no xml attribute that can do scaling for buttons. You can do it programatically though, in the following way :

Bitmap originalBitmap= BitmapFactory.decodeResource(getResources(), R.drawable.icon);
Bitmap scaledBitmap=Bitmap.createScaledBitmap(originalBitmap, newWidth, newHeight, true);
txt.setBackgroundDrawable(new BitmapDrawable(bit));

You could use an ImageButton and try android:scaleType

ImageView.ScaleType

You could scale down the actual graphic that the drawable points to.
