推荐答案

我觉得不能从另一个线程比UI线程做观点的修改，所以无论是创建的 的处理程序在OnCreate并发布您的线程，或者使用的AsyncTask 或<一href="http://developer.android.com/reference/android/app/Activity.html#runOnUiThread%28java.lang.Runnable%29">runOnUIThread方法发送的部分code直接到UI线程。

I think you can't do view modifications from another thread than the UI thread, so either create handlers in the oncreate and post your thread to it, or use AsyncTask, or runOnUIThread method to send portions of code directly to the UI thread.
