[android] 手机卫士接收打电话广播显示号码归属地详解手机开发

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; 
 
/** 
 * 来电显示 
 *  
 * @author taoshihan 
 *  
 */ 
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; 
    } 
}
