android电话拦截及短信过滤

(1) 主界面(main.xml)实现：

<?xmlversion= "1.0" encoding= "utf-8" ?>
<LinearLayoutxmlns: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>
