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>
