Auto flipping of ViewFlipper

Further work on the last exercise "ViewFlipper", we can start and stop auto flipping of ViewFlipper by calling function startFlipping() and stopFlipping(), on interval set by function setFlipInterval(int milliseconds), and the state of flipping can be read by calling function isFlipping().



Modify the layout, main.xml, to add a button to toggle flipping

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<TextView 
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
<Button
 android:id="@+id/buttonautoflip"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="Start Auto Flip"/>
<ViewFlipper
