24.Android-实现黑名单电话拦截

一.知识概括



二.具体代码实现

1.建aidl包





2.拷贝以下文件到项目的aidl包中

下载地址：
NeighboringCellInfo.aidl和ITelephony.aidl





3.在清单文件AndroidManifest.xml中添加权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.zking.android24_zy">

<!-- 授予该应用读取通话状态的权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<!-- 授予该应用控制通话的权限 -->
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

<application android:allowBackup="true" android:icon="@mipmap/ic_launcher"
android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true" android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<!--配置-->
<receiver android:name=".MyBlacklist">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"></action>
</intent-filter>
</receiver>

</application>

</manifest>

4.Java代码MyBlacklist.java

package com.zking.android24_zy;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;

import com.android.internal.telephony.ITelephony;

import java.lang.reflect.Method;

/**
* 黑名单
*/

public class MyBlacklist extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
if("android.intent.action.PHONE_STATE".equals(intent.getAction())){
//1.得到电话管理者
TelephonyManager tm= (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
int state=tm.getCallState();//得到电话的状态
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
//2.得到电话号码
String number=intent.getStringExtra("incoming_number");
Log.i("test","用户"+number+"来电了");
//3.得到电话管理者类对象
Class<TelephonyManager> clazz=TelephonyManager.class;
try {
//4.得到方法(的Method对象)
Method method = clazz.getDeclaredMethod("getITelephony",null);
//5.允许访问私有的方法
method.setAccessible(true);
//6.执行方法
ITelephony iTelephony= (ITelephony) method.invoke(tm,null);
//7.判断是不是这个号码是的话就挂断
if("18711126092".equals(number)){
iTelephony.endCall();//挂断电话
}
break;
} catch (Exception e) {
e.printStackTrace();
}
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;
}
}
}

}

5.效果图

两部手机测试:一部连接Android Studio,一部打电话。如果电话在你的黑名单当中，会提示你所拨打的号码正在通话中。
