AnalogClock时钟

一、AnalogClock时钟显示时间

protected static final int GUINOTIFIER = 0x1234;
	
	private TextView mTextView;
	public AnalogClock mAnalogClock;
	public Calendar mCalendar;
	
	public int mMinutes;
	public int mHour;
	
	public Handler mHandler;
	private Thread mClockThread;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.clock);

		mTextView = (TextView) findViewById(R.id.myTextView);
		mAnalogClock = (AnalogClock) findViewById(R.id.myAnalogClock);

		mHandler = new Handler() {
			public void handleMessage(Message msg) {
				switch (msg.what) {
				case Clock.GUINOTIFIER:
					mTextView.setText(mHour + " : " + mMinutes);
					break;
				}
				super.handleMessage(msg);
			}
		};

		mClockThread = new LooperThread();
		mClockThread.start();
	}

	class LooperThread extends Thread {
		public void run() {
			super.run();
			try {
				do { 
					long time = System.currentTimeMillis();
					final Calendar mCalendar = Calendar.getInstance();
					mCalendar.setTimeInMillis(time);
					mHour = mCalendar.get(Calendar.HOUR);
					mMinutes = mCalendar.get(Calendar.MINUTE);
					Thread.sleep(1000);
					Message m = new Message();
					m.what = Clock.GUINOTIFIER;
					Clock.this.mHandler.sendMessage(m);
				} while (Clock.LooperThread.interrupted() == false); /* 当系统发出中断讯息时停止本循环 */
			} catch (Exception e) {
				e.printStackTrace();
			}
