Android笔记之Thread内部不要处理数据

1、错误做法：

String result = "CHUSHIWENBE";
....
        new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                Log.i("fragment_1_2", "THREAD START!");
                result = HttpClientUtils.sendHttpclientPost(null,
                        CommonUrl.Get_Msg, CommonUrl.encode);
                GsonUlits.getListFromGson(result);
                Log.i("result in thread", result);
            }
        }).start();


        Log.i("result out thread", result);

这样的做法会在线程外对result的使用不会因为线程而发生数据改变

所以还是应该以message的方式来传递和处理数据。

2、错误做法：在Thread里面显示Toast：

java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

Done!
