ViewFlipper realizes the effect of rolling up and down carousel

1 kind of control that can set sliding animation, only display 1 line layout, and write the layout of each line in sequence in ViewFlipper control in layout file

(1).MainActivity.java:

ViewFlipper mFlipper = ((ViewFlipper) this.findViewById(R.id.flipper));
mFlipper.startFlipping();
//  Setting Enter Animation 
mFlipper.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.push_up_in)); 
//  Set up roll-out animation 
mFlipper.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.push_up_out)); 

(2).activity_main.xml:

<ViewFlipper
  android:id="@+id/flipper"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:layout_marginBottom="20dip"
  android:flipInterval="3000" > //  Set the sliding interval (milliseconds) 

  <TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:text="@string/animation_2_text_1"
    android:textSize="26sp" />

  <TextView
