多个Android动画不能同时工作

Question

我有picView.startAnimation(anim);和picView.startAnimation(anim2);，但只有picView.startAnimation(anim2);有效。

当我删除第二个动画时，只有picView.startAnimation(anim);有效。

我希望两个动画同时运行，我做错了什么？

我的代码

public class PicView extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.pic_view);

        LinearLayout myLL = (LinearLayout) findViewById(R.id.LinearLayout2);

        final ImageView picView = new ImageView(this);
        myLL.addView(picView);

        final TextView tv = new TextView(this);
        myLL.addView(tv);


        Animation anim = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button);
        Animation anim2 = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button2);
        picView.setImageResource(R.drawable.a0000);
        picView.startAnimation(anim);
        picView.startAnimation(anim2);

    }
}

您必须创建AnimationSet。

这样的事情：

Animation anim = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button);
Animation anim2 = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button2);

AnimationSet as = new AnimationSet(true);
as.addAnimation(anim);
as.addAnimation(anim2);

viewYouWantToAnimate.setAnimation(as);

as.start();
