android 通過handler實現非同步處理

public class HandlethreadtestActivity extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                HandlerThread myhandlethread=new HandlerThread("my_handler1");// 1.建立一個handlerthread 線程對象 my_handler  是這個線程對象的名稱                myhandlethread.start();//2. 啟動線程        MyHandle myhandle=new MyHandle(myhandlethread.getLooper());//4.綁定到建立的線程上        Message msg=myhandle.obtainMessage();//5. 擷取到msg對象        Bundle b=new Bundle();       b.putInt("age", 12);       b.putString("name", "super_cj");       msg.setData(b);//在msg對象上綁定資料       msg.sendToTarget(); //把msg發送到綁定的線程上    }    class MyHandle extends Handler //3. 建立一個handler的內部類     {    public MyHandle()    {        }    public MyHandle(Looper looper)//重載myhandle  讓父類Handler 把myhandlerthread 加入到線程隊列    {    super(looper);    }@Overridepublic void handleMessage(Message msg) {//線上程裡要做的事  就是你想非同步處理的代碼// TODO Auto-generated method stubsuper.handleMessage(msg);Bundle bb=msg.getData();//獲得msg 傳過來的資料int age=bb.getInt("age");String name=bb.getString("name");Toast.makeText(HandlethreadtestActivity.this, String.valueOf(age), Toast.LENGTH_LONG).show();try{Thread.sleep(5000);//暫停線程5秒Toast.makeText(HandlethreadtestActivity.this, name, Toast.LENGTH_LONG).show();}catch(Exception e){}}        }}

我也是初學 自己寫下來忘記的時候來看看 呵呵 有錯誤的地方請幫忙指出 謝謝！
