本文介绍了一个Android应用程序，能够实现电话和短信的拦截功能。该应用通过注册BroadcastReceiver监听电话状态变化和短信接收事件，对特定号码进行拦截处理。

1. 引言

在Android中实现电话和短信拦截器功能，这个是我从网上找的，并非自己实现，使用时需要修改一下代码（需要拦截的号码），测试已经通过，工程結构和实现如下。

2. 工程结构

工程结构

3. 功能实现

(1) 主界面(main.xml)实现：

view plain copy to clipboard print ?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
android:orientation = "vertical"
android:layout_width = "fill_parent"
android:layout_height = "fill_parent"
>
<Button
android:id = "@+id/enableCallTransfer"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:text = "设置呼叫转移"
/>
<Button
android:id = "@+id/disableCallTransfer"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:text = "取消呼叫转移"
/>
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:orientation = "vertical" android:layout_width = "fill_parent" android:layout_height = "fill_parent" > <Button android:id = "@+id/enableCallTransfer" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:text = "设置呼叫转移" /> <Button android:id = "@+id/disableCallTransfer" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:text = "取消呼叫转移" /> </LinearLayout>

(2) 主Activity实现：
