Chapter 3 The Activity Lifecycle
Now make some changes to the landscape layout so that it is different from the default. Figure 3.12
shows the changes that you are going to make.
Figure 3.12 An alternative landscape layout
A FrameLayout will replace the top LinearLayout. FrameLayout is the simplest ViewGroup and does
not arrange its children in any particular manner. In this layout, child views will be arranged according
to their android:layout_gravity attributes.
This means that the TextView, LinearLayout, and Button children of the FrameLayout need
android:layout_gravity attributes. The Button children of the LinearLayout will stay exactly the
same.
