Android在非UI線程中更新UI的方法

1、使用Thread+Handler實現非UI線程更新UI介面

private MyHandler mHandler = new MyHandler();......mHandler.sendResult(MyHandler.UPDATE_VIEW, null);......       private class MyHandler extends Handler{               private static final int UPDATE_VIEW = 0;               @Override               public void handleMessage(Message msg) {                       switch (msg.what) {                       case UPDATE_VIEW:                               updateView();                               break;                       default:                               break;                       }               }               private void sendResult(int result, Object obj) {                       Message message = new Message();                       message.what = result;                       message.obj = obj;                       sendMessage(message);                       //obtainMessage(result, obj).sendToTarget(); //效率更高               }       }

2、使用View的post方法來更新UI

mView.post(new Runnable() {@Overridepublic void run() {updateView();}});
