[android] How to show the text on a ImageButton?

I solved this by putting the ImageButton and TextView inside a LinearLayout with vertical orientation. Works great!

<LinearLayout
    android:id="@+id/linLayout"
    android:layout_width="80dp"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <ImageButton
        android:id="@+id/camera_ibtn"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_gravity="center"
        android:background="@drawable/camera" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="@string/take_pic"
        android:textColor="#FFFFFF"
        android:textStyle="bold" />

</LinearLayout>
