Android 그림 뒤집기 애니메이션 간단한 구현 코드

다음은 여러분께 재미있는 애니메이션을 공유해 드리겠습니다. 여기는 한 장의 그림을 뒤집기에 비교적 적합합니다. 만약에 여러 장의 그림이라면 APIDemo의 예를 참고하면 ArrayAdapter를 추가하든지 아니면 간단하든지 스스로 수정하여 원하는 것을 실현할 수 있습니다.이곳의 코드는 기본적으로 프로젝트를 직접 운행할 수 있다.이메일xml에 ImageView를 추가합니다.

 
  
 
  
android:id="@+id/container" 
  
android:layout_width="fill_parent" 
  
android:layout_height="fill_parent"> 
  
android:id="@+id/image" 
  
android:layout_width="wrap_content" 
  
android:layout_height="wrap_content" 
  
android:text="Rotate" 
  
android:textSize="50px" 
  
android:layout_x="150px" 
  
android:layout_y="30px" 
  
android:src="@drawable/ro"> 
  
> 
  
 
  
 
 

이것은 설명할 필요가 없겠지, 다 알아볼 수 있으니까.
마지막으로activity류가 하나 더 필요합니다
예:

 
  
public class TestRotate extends Activity implements OnClickListener{ 
  
private mageView imageview; 
  
private ViewGroup mContainer; 
  
/**
