package com.example.android_flipper;

viewFlipper.addView(addTextView(R.drawable.flight));

@Override

return gestureDetector.onTouchEvent(event);
}

@Override

return false;
}

@Override

float velocityY) {
// TODO Auto-generated method stub
if (e1.getX() - e2.getX() > 120) {
viewFlipper.setInAnimation(AnimationUtils.loadAnimation(

}

@Override
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub

}

public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
float distanceY) {
// TODO Auto-generated method stub

@Override
public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub

}

@Override
public boolean onSingleTapUp(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}

}

在res目录下面新建一个folder，命名为anim，在此目录下创建四个xml文件

push_left_in.xml

</set>

push_left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="500"
android:fromXDelta="0"
android:toXDelta="-100%" />

<alpha
android:duration="500"
android:fromAlpha="1.0"
android:toAlpha="0.1" >
</alpha>

</set>

push_right_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
