關於Thread和Handler的使用（一）

public class TestHandlerAty extends Activity {

 

private android.os.Handler mHandler = new Handler();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button btn_start = (Button) findViewById(R.id.btn_start);
        Button btn_stop = (Button) findViewById(R.id.btn_stop);
        btn_start.setOnClickListener(new View.OnClickListener() {

 

@Override

public void onClick(View v) {

mHandler.post(mThread); // 開始調用線程，執行run()方法，輸出run...

}

});
        btn_stop.setOnClickListener(new View.OnClickListener() {

 

@Override

public void onClick(View v) {

mHandler.removeCallbacks(mThread); // 移除mThread，不再輸出run...

}

});
    }

    private Thread mThread = new Thread(new Runnable(){

@Override

public void run() {

Log.d("test", "run...");

mHandler.postDelayed(mThread, 3000);// 3秒鐘之後執行mThread，即run()方法，輸出run...

}

    });

}
