【手机勤务员】android自动切断来电，如果是手机号码回复一条短信

当你的手机需要更换新号码的时候，或者当你出国旅行不需要携带国内手机的时候，你的手机可以放在家中，当有人来电时自动挂断，如果对方是手机号码(11位长首位为1)就回复一条短信。

废话少提，直接上代码！

1、必须有如下权限：

<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

2、在工程的Package Explorer中的src按右键选New、Package，输入：com.android.internal.telephony

3、在com.android.internal.telephony按右键选New、File，文件名：ITelephony.aidl，输入的内容如下：

package com.android.internal.telephony;

interface ITelephony
{
        boolean endCall();
}

4、在MainActivity加入以下代码：

    private ITelephony  iTelephony = null;
    private TelephonyManager iTeleManager = null;

    public void initTelephony() {
    	iTeleManager = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
    	Class <TelephonyManager> c = TelephonyManager.class;
    	Method getITelephonyMethod = null;
    	try {
    		getITelephonyMethod = c.getDeclaredMethod("getITelephony", (Class[])null);
    		getITelephonyMethod.setAccessible(true);
    		iTelephony = (ITelephony) getITelephonyMethod.invoke(iTeleManager, (Object[])null);
    	} catch (IllegalArgumentException e) {
    		e.printStackTrace();
    	} catch (Exception e) {
    		e.printStackTrace();
    	}
    }

    PhoneStateListener psl = new PhoneStateListener() {

    	@Override
    	public void onCallStateChanged(int state, String incomingNumber) {
    	    // TODO Auto-generated method stub
    		super.onCallStateChanged(state, incomingNumber);
    		switch(state){
    		case TelephonyManager.CALL_STATE_RINGING:
			Log.i("DEBUG", "uncall : " + incomingNumber);
			Message msg = new Message();
			msg.what = 3618;
			msg.obj = incomingNumber;
			handler.sendMessage(msg);
    			try {
   				// 当电话接入时，自动挂断。
   				iTelephony.endCall();
    			} catch (RemoteException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    			}
    			break;
    		}
    	}

    };

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		initTelephony();
		iTeleManager.listen(psl, PhoneStateListener.LISTEN_CALL_STATE);
	}

	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
		iTeleManager.listen(null, 0);
	}

    private Handler handler = new Handler() {

		@Override
		public void handleMessage(Message msg) {
			// TODO Auto-generated method stub
			super.handleMessage(msg);
			myHandleMessage(msg);
		}

    };

    private void myHandleMessage(Message msg) {
    	if(msg.what == 3618) {
    		String phoneNumber = (String)msg.obj;
    		if(phoneNumber.length() == 11 && phoneNumber.charAt(0) == '1') {
    			 SmsManager sms = SmsManager.getDefault();
    			 String smsmsg = "您好，机主已经更新号码，有事请拨打：188 2318 3718。【手机勤务员】竭诚为您提供优质服务！";
    			 sms.sendTextMessage(phoneNumber, null, smsmsg, null, null);
    		}
    	}
    }

至此，手机勤务员的自动挂机并短信通知的优质服务宣告完成！
