android - AnimationDrawable 线程跳帧

Question

我在一个 Activity 中，它必须在加载其余内容时播放 AnimationDrawable（“加载”动画）。我在另一个线程中开始了动画，因为动画往往会给主线程很多工作，但是动画无法正确显示，并且 Logcat 多次显示已跳过 40 帧左右。明天我会发布代码，抱歉延迟。同时是什么原因造成的？所有线程内部都是动画drawable的启动方法。

You should not run animation off of the UI thread ("main" thread) - you should load your content in another thread by using a Loader (or something similar) and play the animation on the UI thread. That's what it's for.

Here are official thread guidelines:

Do not block the UI thread

Do not access the Android UI toolkit from outside the UI thread
