[android] 手机卫士接收打电话广播显示号码归属地

使用广播接收者接收打电话的意图，显示号码归属地

新建一个类OutCallReceiver继承系统的BroadcastReceiver

重写onReceive()方法

调用getResultData()方法，获取到String电话号码，查询数据库获取到归属地

package com.qingguow.mobilesafe.receiver;

import com.qingguow.mobilesafe.utils.NumberQueryAddressUtil;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
/**
 * 接收打电话广播
 * @author taoshihan
 *
 */
public class OutcallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        String phone=getResultData();
        String address=NumberQueryAddressUtil.queryAddress(phone);
        System.out.println("111"+address);
        Toast.makeText(arg0, address, 1).show();
    }

}

清单文件中定义<receiver>节点，和<intent-filter>节点，设置<action>节点名称，android:name=”android.intent.action.NEW_OUTGOING_CALL”

需要权限，android.permission.PROCESS_OUTGOING_CALLS

 代码注册广播

此时的广播接收者，只要一打电话就会被调用，用户体验不好，我们使用代码注册广播接收者，用设置中心的开启监听电话来电的部分来控制这个广播

在服务里面调用registerReceiver()方法，注册广播，参数：BroadcastReceiver对象，IntentFilter对象

获取IntentFilter对象，调用IntentFilter对象的addAction()方法，参数：android.intent.action.NEW_OUTGOING_CALL

在服务里面解除注册广播，调用unregisterReceiver()方法，参数：BroadcastReceiver对象

package com.qingguow.mobilesafe.service;

import com.qingguow.mobilesafe.receiver.OutcallReceiver;
import com.qingguow.mobilesafe.utils.NumberQueryAddressUtil;

import android.app.Service;
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 MyPhoneStateListener phoneStateListener;
    private OutcallReceiver outcallReceiver;
    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }
    /**

    @Override
    public void onCreate() {
        super.onCreate();
        tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
        phoneStateListener = new MyPhoneStateListener();
        tm.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

        //注册广播
        outcallReceiver=new OutcallReceiver();
        IntentFilter filter=new IntentFilter();
        filter.addAction("android.intent.action.NEW_OUTGOING_CALL");
        registerReceiver(outcallReceiver, filter);
    }

    private class MyPhoneStateListener extends PhoneStateListener {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            super.onCallStateChanged(state, incomingNumber);
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                String info = NumberQueryAddressUtil
                        .queryAddress(incomingNumber);
                Toast.makeText(getApplicationContext(), info, 1).show();
                break;
            default:
                break;
            }
        }
    }

        super.onDestroy();
        //取消监听
        tm.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);
        phoneStateListener=null;
        //解除注册广播
        unregisterReceiver(outcallReceiver);
        outcallReceiver=null;
    }
