本文实例为大家分享了android来电拦截的方法，供大家参考，具体内容如下

权限

  <uses-permission android:name="android.permission.read_phone_state" />
  <uses-permission android:name="android.permission.call_phone" />
  <uses-permission android:name="android.permission.process_outgoing_calls" />

 <!-- 注册广播 监听拨出电话 -->
 <receiver android:name="com.example.administrator.endcall.phonestatereceiver">
      <intent-filter>
        <action android:name="android.intent.action.phone_state" />
        <action android:name="android.intent.action.new_outgoing_call" />
      </intent-filter>
 </receiver>

拨号广播—phonestatereceiver

package com.example.administrator.endcall;

import android.content.broadcastreceiver;
import android.content.context;
import android.content.intent;
import android.telephony.phonestatelistener;
import android.telephony.telephonymanager;
import android.util.log;

public class phonestatereceiver extends broadcastreceiver {
  @override
  public void onreceive(context context, intent intent) {
    if (intent.getaction().equals(intent.action_new_outgoing_call)) {
      string phonenumber = intent.getstringextra(intent.extra_phone_number);
      log.i("blockcallhelper", "blockcallhelper------->>>>" + phonenumber);
    }
  }
}


来电挂断
blockcallhelper

package com.example.administrator.endcall;

import android.content.context;
import android.content.sharedpreferences;
import android.database.cursor;
import android.net.uri;
import android.os.remoteexception;
import android.telephony.phonestatelistener;
import android.telephony.telephonymanager;
import android.util.log;

import com.android.internal.telephony.itelephony;

import java.lang.reflect.invocationtargetexception;
import java.lang.reflect.method;
import java.util.arraylist;
import java.util.list;

public final class blockcallhelper {
  private static final string tag = "blockcallhelper";

  private context mcontext;

  private telephonymanager tmanger;

  private list<string> phones;

  private blockcallback bcb;

  //////////////////////////////////////////
  private static final class factory {
    private static final blockcallhelper instance = new blockcallhelper();
  }

  public static blockcallhelper getinstance() {
    return factory.instance;
  }

  /**
   * 初始化上下文以及数据
   * @param context
   */
  public blockcallhelper init(context context) {
    if (context == null) {
      throw new nullpointerexception("context == null!");
    }

    this.mcontext = context;
    this.tmanger = (telephonymanager) mcontext.getsystemservice(context.telephony_service);
    tmanger.listen(new phonecalllistener(), phonecalllistener.listen_call_state);
    return this;
  }

  /**
   * 注入需要拦截的手机号
   * @param phonel
   */
  public blockcallhelper injectblockphonenum(arraylist<string> blockcalls) {
    this.phones = blockcalls;
    return this;
  }
  /**
   * 结束通话
   */
  private void endcall() {
    class<telephonymanager> tmc = telephonymanager.class;
    method getitelephonymethod;
    try {
      getitelephonymethod = tmc.getdeclaredmethod("getitelephony", (class[]) null);
      getitelephonymethod.setaccessible(true);
      itelephony itelephony = (itelephony) getitelephonymethod.invoke(tmanger, (object[]) null);
      itelephony.endcall();
    } catch (nosuchmethodexception e1) {
      e1.printstacktrace();
    } catch (invocationtargetexception e2) {
      e2.printstacktrace();
    } catch (illegalaccessexception e3) {
      e3.printstacktrace();
    } catch (remoteexception e4) {
      e4.printstacktrace();
    }
  }

  private final class phonecalllistener extends phonestatelistener {
    @override
    public void oncallstatechanged(int state, string incomingnumber) {
      if (state == telephonymanager.call_state_ringing) {
        if (phones.contains(incomingnumber)) {
          log.i("blockcallhelper", "contains contains contains");
          endcall();
          if (bcb != null) {
            bcb.callback(incomingnumber);
          }
        } else {
          log.i("blockcallhelper", "contains not-------");
        }
      }
    }
  }

  public blockcallhelper setblockcallback(blockcallback back) {
    this.bcb = back;
    return this;
  }

  public interface blockcallback {
    void callback(string incomingnum);
  }
}

看主界面mainactivity

package com.example.administrator.endcall;

import android.app.activity;
import android.app.notificationmanager;
import android.os.bundle;
import android.util.log;
import android.widget.toast;

import java.util.arraylist;

public class mainactivity extends activity {

  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.activity_main);
    arraylist<string> blockcalls = new arraylist();
    blockcalls.add("13581922339");
    blockcalls.add("+8613581922339");
    blockcalls.add("18500813370");
    blockcalls.add("13717717622");
    blockcalls.add("+8613717717622");

    blockcallhelper.getinstance().init(this).injectblockphonenum(blockcalls).setblockcallback(new blockcallhelper.blockcallback() {
      @override
      public void callback(string incomingnum) {
        log.i("blockcallhelper", "incomingnum-----------" + incomingnum);
      }
    });
  }
}

最后看aidl层面
itelephony.aidl

package com.android.internal.telephony;

interface itelephony {
   void dial(string number);
   void call(string number);
   boolean showcallscreen();
   boolean showcallscreenwithdialpad(boolean showdialpad);
   boolean endcall();
   void answerringingcall();
   void silenceringer();
   boolean isoffhook();
   boolean isringing();
   boolean isidle();
   boolean isradioon();
   boolean issimpinenabled();
   void cancelmissedcallsnotification();
   boolean supplypin(string pin);
   boolean handlepinmmi(string dialstring);
   void toggleradioonoff();
   boolean setradio(boolean turnon);
   void updateservicelocation();
   void enablelocationupdates();
   void disablelocationupdates();
   int enableapntype(string type);
   int disableapntype(string type);
   boolean enabledataconnectivity();
   boolean disabledataconnectivity();
   boolean isdataconnectivitypossible();

   bundle getcelllocation();
   list<neighboringcellinfo> getneighboringcellinfo();

    int getcallstate();
    int getdataactivity();
    int getdatastate();
}

neighboringcellinfo.aidl

// neighboringcellinfo.aidl
package android.telephony;
parcelable neighboringcellinfo;
