有没有区别
new Handler.post(Runnable r);
和
activity.runOnUiThread(Runnable r)
最佳答案
来自官方Handler文档
处理程序
处理程序有两个主要用途:
(1) To schedule messages and runnables to be executed as some point in the future.
(2) To enqueue an action to be performed on a different thread than your own.
简而言之，Handler就是用来管理不同的Runnables的。
runOnUiThread
It is used to execute the non-UI operation on the UI Thread, example if you want to update the screen from AsyncTask's doInBackground() you have to write the part of code that update's the UI inside the runOnUiThread(). But again that will block the UI.
