39监听去电

定义一个广播接受者：

package com.ustc.mobilemanager.receiver;

import com.ustc.mobilemanager.db.dao.NumberAddressQueryUtils;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class OutCallReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		// 这就是我们拿到的拨出去的电话号码
		String phone = getResultData();
		// 查询数据库
		String address = NumberAddressQueryUtils.queryNumber(phone);
		Toast.makeText(context, address, 1).show();

	}

}

getResultData得到的即时拨打的号码。但是这样有个问题，这个广播接受者就算应用死掉了他还是在监听状态中，我们把这个类移到服务中，使用代码注册。

package com.ustc.mobilemanager.service;

import com.ustc.mobilemanager.db.dao.NumberAddressQueryUtils;

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.widget.Toast;

public class AddressService extends Service {

	private TelephonyManager tm;

	private MyListenerPhone listenerPhone;
	
	private OutCallReceiver outCallReceiver;

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

	//服务里面的内部类
	class OutCallReceiver extends BroadcastReceiver {

		@Override
		public void onReceive(Context context, Intent intent) {
			// 这就是我们拿到的拨出去的电话号码
			String phone = getResultData();
			// 查询数据库
			String address = NumberAddressQueryUtils.queryNumber(phone);
			Toast.makeText(context, address, 1).show();

		}
	}

	private class MyListenerPhone extends PhoneStateListener {

		@Override
		public void onCallStateChanged(int state, String incomingNumber) {
			super.onCallStateChanged(state, incomingNumber);

			switch (state) {
			case TelephonyManager.CALL_STATE_RINGING:// 来电铃声响起
				// 查询数据库的操作
				String address = NumberAddressQueryUtils
						.queryNumber(incomingNumber);
				Toast.makeText(getApplicationContext(), address, 1).show();
				break;

			default:
				break;
			}

		}

	}

	@Override
	public void onCreate() {
		super.onCreate();
		tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);

		listenerPhone = new MyListenerPhone();

		tm.listen(listenerPhone, PhoneStateListener.LISTEN_CALL_STATE);
		
		
		
		//代码去注册一个广播接受者
		outCallReceiver = new OutCallReceiver();
		
		IntentFilter filter = new IntentFilter();
		
		filter.addAction("android.intent.action.NEW_OUTGOING_CALL");
		
		registerReceiver(outCallReceiver, filter);

	}

	@Override
	public void onDestroy() {
		super.onDestroy();
		tm.listen(listenerPhone, PhoneStateListener.LISTEN_NONE);
		listenerPhone = null;
		
		//取消注册
		unregisterReceiver(outCallReceiver);
		outCallReceiver = null;
		
	}

}

在onCreate中实例化，在onDestroy中取消注册。
