如何将旋转动画与平移动画结合使用？

Question

我在示例应用程序中使用手势侦听器，并在其中的 onFling() 方法中我想执行旋转和平移动画。

individual 都工作正常，但是当我将其集成到 Animation Set 中时，它无法正常工作。

请建议我如何处理这个问题。

以下是我的 onFling 方法的代码：

onFling(MotionEvent e1, MotionEvent e2, floatvelocityX, 浮动速度Y) {

    translateAnimation =  new TranslateAnimation(0,x2,0,y2); // x2=e2.getX() and y2=e2.getY()

    translateAnimation.setDuration(3000);

    rotateAnimation = new RotateAnimation(0, 90, RotateAnimation.RELATIVE_TO_SELF, RotateAnimation.RELATIVE_TO_SELF);

    rotateAnimation.setStartOffset(1400);

    rotateAnimation.setInterpolator(new AccelerateInterpolator());


    animationSet.addAnimation(translateAnimation);

    animationSet.addAnimation(rotateAnimation);

    animationSet.setAnimationListener(this);

    animationSet.setDuration(3000);

    lastView.startAnimation(animationSet);

}

非常感谢

试试这个

 @Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.rotate);
    AnimationSet snowMov1 = new AnimationSet(true);
    RotateAnimation rotate1 = new RotateAnimation(0, 360,
            Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
            0.5f);
    rotate1.setStartOffset(50);
    rotate1.setDuration(300);
    rotate1.setRepeatCount(-1);
    snowMov1.addAnimation(rotate1);
    TranslateAnimation trans1 = new TranslateAnimation(
            Animation.RELATIVE_TO_PARENT, 0.1f,
            Animation.RELATIVE_TO_PARENT, 0.3f,
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, 0.9f);
    trans1.setDuration(300);
    trans1.setRepeatCount(-1);

    snowMov1.addAnimation(trans1);
    ImageView view = (ImageView) findViewById(R.id.image);
    view.startAnimation(snowMov1);

}
