用代码实现来电拦截
如果要进行来电拦截，首先要定义权限，然后写一个接收来电去电的广播。由于不同机型的问题，动态注册还是静态注册有待商榷，我这里用的是静态注册，模拟器测试通过。
一、申请权限
<!-- 添加访问手机电话状态的权限 --> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <!-- 拨打电话权限 --> <uses-permission android:name="android.permission.CALL_PHONE"/> <!-- 监听手机去电的权限 --> <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
二、注册广播
<!-- 拨打电话触发的广播 --> <receiver android:name="com.kale.phoneblock.PhoneReceiver"> <intent-filter android:priority="1000"> <action android:name="android.intent.action.PHONE_STATE"/> <action android:name="android.intent.action.NEW_OUTGOING_CALL" /> </intent-filter> </receiver>
三、复制aidl文件
由于高版本的系统中没给出操作电话的api，所以我们要在src文件下新建连个包，放两个文件进去。重要的是ITelephony文件，上面那个文件似乎可以不管它。
NeighboringCellInfo.aidl

四、编写广播接收类——PhoneReceiver
4.1 TelephonyManager
TelephonyManager是用来操作电话的控制器，通过它我们可以对来/去电来绑定监听器
@Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) { // 如果是去电（拨出） } else { TelephonyManager tm = (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE); // 设置一个监听器 tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE); } }
4.2 处理监听事件
绑定监听器后我们就要根据监听到的不同的情况写不同的代码了
PhoneStateListener listener = new PhoneStateListener() { @Override public void onCallStateChanged(int state, String incomingNumber) { // state 当前状态 incomingNumber,貌似没有去电的API super.onCallStateChanged(state, incomingNumber); switch (state) { //手机空闲了 case TelephonyManager.CALL_STATE_IDLE: break; //电话被挂起 case TelephonyManager.CALL_STATE_OFFHOOK: break; // 当电话呼入时 case TelephonyManager.CALL_STATE_RINGING: Log.e(TAG, "来电号码是："+ incomingNumber); // 如果该号码属于黑名单 if (incomingNumber.equals("123456")) { // TODO:如果是黑名单，就进行屏蔽 stopCall(); } break; } } };
4.3 挂断电话
public void stopCall() { try { Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class); // 获取远程TELEPHONY_SERVICE的IBinder对象的代理 IBinder binder = (IBinder) method.invoke(null, new Object[] { "phone" }); // 将IBinder对象的代理转换为ITelephony对象 ITelephony telephony = ITelephony.Stub.asInterface(binder); // 挂断电话 telephony.endCall(); telephony.cancelMissedCallsNotification(); } catch (Exception e) { } }
4.4全部代码
package com.kale.phoneblock; import java.lang.reflect.Method; import android.app.Service; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.IBinder; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log; import com.android.internal.telephony.ITelephony; public class PhoneReceiver extends BroadcastReceiver { String TAG = "PhoneReceiver"; @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) { // 如果是去电（拨出） } else { TelephonyManager tm = (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE); // 设置一个监听器 tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE); } } PhoneStateListener listener = new PhoneStateListener() { @Override public void onCallStateChanged(int state, String incomingNumber) { // state 当前状态 incomingNumber,貌似没有去电的API super.onCallStateChanged(state, incomingNumber); switch (state) { //手机空闲了 case TelephonyManager.CALL_STATE_IDLE: break; //电话被挂起 case TelephonyManager.CALL_STATE_OFFHOOK: break; // 当电话呼入时 case TelephonyManager.CALL_STATE_RINGING: Log.e(TAG, "来电号码是："+ incomingNumber); // 如果该号码属于黑名单 if (incomingNumber.equals("123456")) { // TODO:如果是黑名单，就进行屏蔽 stopCall(); } break; } } }; public void stopCall() { try { Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class); // 获取远程TELEPHONY_SERVICE的IBinder对象的代理 IBinder binder = (IBinder) method.invoke(null, new Object[] { "phone" }); // 将IBinder对象的代理转换为ITelephony对象 ITelephony telephony = ITelephony.Stub.asInterface(binder); // 挂断电话 telephony.endCall(); telephony.cancelMissedCallsNotification(); } catch (Exception e) { } } }
五、运行效果
环境：2.2模拟器
接电话时会触发监听器，测试中会出现一次或多次触发监听器。对于要屏蔽的号码进行了完全的拦截，测试成功！
只触发一次的情况：
多次触发的情况：
