android-imageView中旋轉動畫的問題

imageView中旋轉動畫的問題

在屏幕上有一個ImageView，我想讓這個視圖可以向左旋轉，然後再向右旋轉，我使用以下代碼給ImageView添加動畫：

new RotateAnimation(20f, 50f,Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);

anim.setInterpolator(new LinearInterpolator());
anim.setRepeatCount(Animation.INFINITE);
anim.setDuration(700);

// Start animating the image
final ImageView splash = (ImageView) findViewById(R.id.mobileshake);
splash.startAnimation(anim);

問題是，現在ImageView的這個動畫形式只能旋轉一次。我想的是先向左旋轉，然後再向右旋轉。
如何能讓ImageView動起來？

最佳回答：

使用以下代碼可以實現動畫

final RotateAnimation anim1 = new RotateAnimation(20f, 50f,Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        anim1.setInterpolator(new LinearInterpolator());
        //anim1.setRepeatCount(Animation.INFINITE);
        anim1.setDuration(300);

        final RotateAnimation anim2 = new RotateAnimation(50f, 20f,Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        anim2.setInterpolator(new LinearInterpolator());
        //anim2.setRepeatCount(Animation.INFINITE);
        anim2.setDuration(300);

        final ImageView splash = (ImageView) findViewById(R.id.mobileshake);
        anim1.setAnimationListener(new AnimationListener(){

            public void onAnimationEnd(Animation animation) {
                // TODO Auto-generated method stub
                splash.startAnimation(anim2);
            }

            public void onAnimationRepeat(Animation animation) {
                // TODO Auto-generated method stub

            }

            public void onAnimationStart(Animation animation) {
                // TODO Auto-generated method stub

            }});
        anim2.setAnimationListener(new AnimationListener(){

            public void onAnimationEnd(Animation animation) {
                // TODO Auto-generated method stub
                splash.startAnimation(anim1);
            }

            public void onAnimationRepeat(Animation animation) {
                // TODO Auto-generated method stub

            }

            public void onAnimationStart(Animation animation) {
                // TODO Auto-generated method stub

            }});

        splash.startAnimation(anim1);
