div id=”content” contentScore=”332″>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。
- 工程结构
- 功能实现
(1) 主界面(main.xml)实现：
- “1.0” encoding=“utf-8”?>
- “http://schemas.android.com/apk/res/android”
- android:orientation = “vertical”
- android:layout_width = “fill_parent”
- android:layout_height = “fill_parent”
- >
-
-
- android:id = “@+id/enableCallTransfer”
- android:layout_width = “wrap_content”
- android:layout_height = “wrap_content”
- android:text = “设置呼叫转移”
- />
-
-
- android:id = “@+id/disableCallTransfer”
- android:layout_width = “wrap_content”
- android:layout_height = “wrap_content”
- android:text = “取消呼叫转移”
- />
-
-
(2) 主Activity实现：
