java - 加载动画在前 ICS 设备上启动，但不会在后 ICS 设备上启动

Question

我遇到一个问题，加载动画(5 个连续点从左向右移动)在 ICS 后设备中不起作用，但在 ICS 前设备中完美运行。我尝试在两者中复制调用动画的相同方法，但它似乎不起作用。

提前致谢，

Answer 1

来自开发者文档 http://developer.android.com/guide/topics/resources/animation-resource.html#Frame
该示例显示了对动画的 start() 方法的调用。

ImageView rocketImage = (ImageView) findViewById(R.id.rocket_image);
rocketImage.setBackgroundResource(R.drawable.rocket_thrust);

rocketAnimation = (AnimationDrawable) rocketImage.getBackground();
rocketAnimation.start(); // <--------- Does no harm to PRE ICS devices 

如果您要针对各种 droid 版本(包括 JB)，为什么不调用此方法？
