[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;
}
/**
* 服务创建
*/
@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;
}
}
}
/**
* 服务销毁
*/
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
//取消监听
tm.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);
phoneStateListener=null;
//解除注册广播
unregisterReceiver(outcallReceiver);
outcallReceiver=null;
}
}
