我使用setBackgroud添加一些动画,像这样的代码

AnimationDrawable animation = new AnimationDrawable();
                                 animation.addFrame(getResources().getDrawable(R.drawable.d1),200);
                                 animation.addFrame(getResources().getDrawable(R.drawable.dio),1000);
                                 animation.addFrame(getResources().getDrawable(R.drawable.da1),200);
 animation.setOneShot(true);
 view.setBackground(animation);
 view.post(new Starter(animation));

我有支持库添加到我的项目,我不知道如何解决这个,任何帮助将被apreciated！
