android電話狀態的監聽

電話狀態的監聽:

/***
	 * 繼承PhoneStateListener類，我們可以重新其內部的各種監聽方法 然後通過手機狀態改變時，系統自動觸發這些方法來實現我們想要的功能
	 */
	class MyPhoneStateListener extends PhoneStateListener {

		@Override
		public void onCallStateChanged(int state, String incomingNumber) {
			switch (state) {
			case TelephonyManager.CALL_STATE_IDLE:
				Log.v(tag, "空閒狀態 ");
				break;
			case TelephonyManager.CALL_STATE_RINGING:
				Log.v(tag, "手機鈴聲響了，來電號碼:" + incomingNumber);
