Here's a part from my XML for LAND format:
<TableLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:stretchColumns="*">
<TableRow>
<Button
android:id="@+id/countbutton"
android:text="@string/plus1"/>
<Button
android:id="@+id/resetbutton"
android:text="@string/reset"
/>
</TableRow>
</TableLayout>
And now what I dont get - the WIDTH of one row and also of the button depends on the TEXT inside the button. If the both texts are equaly long lets say : TEXT its ok - the table half is in the middle of the screen. But if they have different size - lets say "A" and "THIS IS THE LONG BUTTON" the CENTER of the table isnt in the middle of the screen anymore and so the buttons are not equally width...
