假设我的活动UI线程生成一个单独的线程在一些点。它是安全的新的线程来断火的意图展开新的活动？

Suppose my activity ui-thread spawns a separate thread at some point. Is it safe for that new thread to fire off an Intent for launching a new activity?

感谢

推荐答案

我可能是错的，但我觉得 startActivity（）内部在UI线程中执行。所以，是的，它应该是安全的。

I could be wrong, but I think startActivity() internally executes in the UI thread. So yes, it should be safe.

如果你想成为100％的把握，调用你的 startActivity（）在活动的 runOnUiThread（）作为一个的Runnable 。

If you wanted to be 100% sure, invoke your startActivity() in your activity's runOnUiThread() as a Runnable.
