Androidの3Dフリップアニメーション

Question

私はeclipesを使用してアンドロイドカードゲームを作成しています。アニメーションを呼び出すと何らかの理由でアプリケーションがクラッシュします。私がしなければならなかった変更の1つはFlipクラスで、それはアニメーションメソッド "createDisplayNextView"にエラーがあったため、layoutviewをimageviewに変更していました。

////////ANIMATION 
    private ImageView FrontView; 
    private ImageView BackView; 
    private boolean isFirstImage = true; 
private void applyRotation(float start, float end) { 
    // Find the center of image 

    FrontView = (ImageView) findViewById(R.id.imgC1); 
    BackView = (ImageView) findViewById(R.drawable.clubs2); 
    BackView.setVisibility(View.GONE); 

    final float centerX = FrontView.getWidth()/2.0f; 
    final float centerY = FrontView.getHeight()/2.0f; 

    // Create a new 3D rotation with the supplied parameter 
    // The animation listener is used to trigger the next animation 
    final cardFlip rotation = new cardFlip(start, end, centerX, centerY); 
    rotation.setDuration(500); 
    rotation.setFillAfter(true); 
    rotation.setInterpolator(new AccelerateInterpolator()); 
    rotation.setAnimationListener(rotation.createDisplayNextView(isFirstImage, FrontView, BackView)); 

    if (isFirstImage) { 
     FrontView.startAnimation(rotation); 
    } else { 
     BackView.startAnimation(rotation); 
    } 
}

これはフリップクラスです：

あなたはこれを試すことができます。..

public class SplashActivity extends Activity { 
    // protected boolean _active = true; 
    protected int _splashTime = 5000; 
    private ImageView imag; 
    AnimationDrawable frameAnimation ; 


    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     setContentView(R.layout.splashactivity); 
     imag = (ImageView) findViewById(R.id.splashactivity_imag); 

     imag.setBackgroundResource(R.drawable.splash_animation); 

      frameAnimation = (AnimationDrawable) imag 
       .getBackground(); 

      Thread splashTread = new Thread() { 
       public void run() { 
        try { 
         sleep(_splashTime); 
        } catch (InterruptedException e) { 
         e.printStackTrace(); 
        } finally { 
         Intent intent; 
         intent = new Intent(SplashActivity.this, HomeActivity.class); 
         startActivity(intent); 
         finish(); 
        } 
       } 
      }; 
      splashTread.start(); 
     } 

    @Override 
    public void onWindowFocusChanged(boolean hasFocus) { 
     super.onWindowFocusChanged(hasFocus); 
     frameAnimation.start(); 

    } 

} 

新しいXMLを作成中に描画可能...
