代码创建LinearLayout,Services监听线程

1.主Activity:

private TextView tx;
	private Button btn;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		// setContentView(R.layout.main);

		LinearLayout layout = new LinearLayout(this);

		layout.setOrientation(LinearLayout.VERTICAL);

		LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(150, 40);
		param.topMargin = 5;

		tx = new TextView(this);
		tx.setTextSize(16);
		tx.setTextColor(Color.BLUE);
		// tx.setBackgroundResource(R.drawable.x_yellow);
		layout.addView(tx, param);

		btn = new Button(this);
		btn.setText("Exit");
		// btn.setBackgroundResource(R.drawable.earth);
		btn.setOnClickListener(this);

		layout.addView(btn, param);
		this.setContentView(layout);

		String tna = Thread.currentThread().getName();
		Thread.currentThread().setName(tna + "-Ac_and_Se");

		MyService.setUpdateListener(new UpdateUIListener());

		Intent svc = new Intent(this, MyService.class);
		startService(svc);
	}

	public void onClick(View v) {
		this.finish();
	}

	class UpdateUIListener implements IListener {
		public void update(String s) {
			System.out.println("__________________"+s);
			tx.setText(s);
		}
	}

	@Override
	protected void onDestroy() {
		super.onDestroy();
		{
			Intent svc = new Intent(this, MyService.class);
			stopService(svc);
		}
	}

2.监听线程的Services:

public class MyService extends Service {
	
	// 监听器对象的实例
	private static IListener plis;
	// private static int k = 0;
	private Timer timer = new Timer();
	private String tna;

	public Handler handler = new Handler() {
		public void handleMessage(Message msg) {
			plis.update(tna);
		}
	};

	@Override
	public void onCreate() {
		super.onCreate();
		tna = Thread.currentThread().getName();
		TimerTask task = new TimerTask() {
			@Override
			public void run() {
				handler.sendEmptyMessage(0);
			}
		};
		timer.schedule(task, 1000, 4000);
	}

	@Override
	public IBinder onBind(Intent intent) {
		return null;
	}

	public static void setUpdateListener(IListener listener) {
		plis = listener;
	}

}

3.最后是一个简单的接口:

public interface IListener {
	public void update(String s);
}

当然这个Services一定要在Manifest.xml中进行申明:

<service android:name=".MyService"></service>
