Android之电话拦截

                     今天来和大家一起分享一下我最近写的一个Demo,类似于黑名单访问,也就是我们俗称的电话拦截

                      首先我们需要两个aidl文件

                      第一个:NeighboringCellInfo.aidl

package android.telephony;

parcelable NeighboringCellInfo;
                      第二个:ITelephony.aidl

package com.android.internal.telephony;

import android.os.Bundle;
import java.util.List;
import android.telephony.NeighboringCellInfo;


interface ITelephony { 

    /**
     * Dial a number. This doesn't place the call. It displays
     * the Dialer screen.
     * @param number the number to be dialed. If null, this

     */
    boolean showCallScreen();

    /**

    Bundle getCellLocation();

    List getNeighboringCellInfo();

     int getCallState();
     int getDataActivity();
     int getDataState();

     */
    boolean hasIccCard();
}

              将这两个aidl文件copy进去之后,我们再来新建一个activity,并且让他继承 BroadcastReceiver这个类

      代码如下:

public class MyPhoneStateReceived extends BroadcastReceiver {@Override
public void onReceive(Context context, Intent intent) {
    if("android.intent.action.PHONE_STATE".equals(intent.getAction())){
        //得到电话管理者
        TelephonyManager telephonyManager= (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        //得到电话的状态
        int state=telephonyManager.getCallState();
        switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:

                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Log.i("test","通话中...录音中");
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                Log.i("test","挂了");
                break;
        }

    //得到电话号码
    String number=intent.getStringExtra("incoming_number");
    Log.i("test","来电了"+number);
    //得到电话管理者类对象
    Class clazz=TelephonyManager.class;
    //得到方法
    try {
        Method method=clazz.getDeclaredMethod("getITelephony",null);
        //设置可访问
        method.setAccessible(true);
        //执行方法
        ITelephony iTelephony= (ITelephony) method.invoke(telephonyManager,null);
        //判断
        Log.i("tt","我拦截的号码!!!"+number);
        if("xxxxxx".equals(number)){
            Log.i("tt","是我拦截的号码!!!");
            iTelephony.endCall();
        }
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (RemoteException e) {
        e.printStackTrace();
    }

    }
}
}

         
           xxxxxx里面填你们想要拦截的电话号码就可以了,这样,电话拦截就做好了
