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！
解决方法
那是在
API 16添加,尝试setBackgroundDrawable()
