About the frameLayout

[mBigFlower]

Why do you use the FrameLayout to contain the ImageView like this:

 <FrameLayout
        android:id="@+id/content_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
                android:id="@android:id/empty"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:gravity="center"
                android:textAppearance="?android:attr/textAppearanceLarge"/>
</FrameLayout>

Is it necessary? Can I remove the FrameLayout ?
