To ViewFlipper add animation error, Unknown interpolator name: set

you great God, I added in a sliding viewFlipper gestures, gestures to determine according to the sliding direction, then there is a simple toggle animation, but the run time error Unknown interpolator name: set I thought I was wrong xml definition of animation, but it is not found error ah

Here is the java code

 public class ShowDataActivity extends Activity {

private QueryDataHandler query; 
private ViewFlipper flipper; 
private GestureDetector gesture; 


@ Override 
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState); 
LinearLayout linear = new LinearLayout (this); 
linear.setLayoutParams (new LinearLayout.LayoutParams (LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 
query = new QueryDataHandler (this); 


gesture = new GestureDetector (this, new GestureDetector.OnGestureListener () {




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

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

} 

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

@ Override 
public boolean onScroll (MotionEvent e1, MotionEvent e2, float distanceX, 
float distanceY) {



return false; 
} 

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

} 

@ Override 
public boolean onFling (MotionEvent e1, MotionEvent e2, float velocityX, 
float velocityY) {
if (e2.getX () - e1.getX ()> 120) 
{
Animation out = (Animation) AnimationUtils.loadInterpolator (ShowDataActivity.this, R.anim.push_right_out); / / this page from left to right to go out 
Animation enter = (Animation) AnimationUtils.loadInterpolator (ShowDataActivity.this, R.anim.push_right_in) ;/ / Next from left to right into the 

flipper.setInAnimation (enter); 
flipper.setOutAnimation (out); 


flipper.showPrevious (); 
} 

if (e2.getX () - e1.getX () <-120) 
{
Animation in = (Animation) AnimationUtils.loadInterpolator (ShowDataActivity.this, R.anim.push_left_in); / / Next right to left into 
Animation out = (Animation) AnimationUtils.loadInterpolator (ShowDataActivity.this, R.anim.push_left_out); / / this page from right to left out 

flipper.setInAnimation (in); 
flipper.setOutAnimation (out); 

flipper.showNext (); 
} 


return false; 
} 

}); 



String rank = query.getCityAirQualityRank (); 
List  last10 = DataAnalysis.getLast10City (DataAnalysis.getCityAirQualitySorted (rank)); 
List  top10 = DataAnalysis.getTop10City (DataAnalysis.getCityAirQualitySorted (rank)); 

RetangleDataView last10view = new RetangleDataView (this, last10); 
RetangleDataView top10view = new RetangleDataView (this, top10); 



flipper = new ViewFlipper (this); 
flipper.addView (top10view, new LinearLayout.LayoutParams (LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 
flipper.addView (last10view, new LinearLayout.LayoutParams (LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 
linear.addView (flipper, new LinearLayout.LayoutParams (LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 

setContentView (linear); 

} 

public boolean onTouchEvent (MotionEvent event) {

return gesture.onTouchEvent (event); / / Register gesture events 
} 

} 

Here is my definition animation xml

  
 
android: duration = "1500" 
android: fromXDelta = "100% p" 
android: toXDelta = "0" /> 

android: duration = "1500" 
android: fromAlpha = "0.1" 
android: toAlpha = "1.0" />

Alas, careless kill people ah. . . AnimationUtils wrong way
