LinearLayoutGridTest

public class LinearLayoutGridTest extends android.test.SingleLaunchActivityTestCase
Tests focus searching between buttons within a grid that are touching, for example, two buttons next two each other would have the left button's right equal to the right button's left. Same goes for top and bottom edges. This exercises some edge cases of {@link android.view.FocusFinder}.
