I do not understand this example:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#015488"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="@string/novo_gasto"
android:textAppearance=
"?android:attr/textAppearanceLarge"
android:textStyle="bold" />
<TextView
android:id="@+id/destino"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textAppearance=
" ?android:attr/textAppearanceLarge"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
</ScrollView>
