android电话拦截及短信过滤

(1) 主界面(main.xml)实现：

<?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：

请问　楼主：mITelephony.endCall();　android 1.0以后是不是就没有用了呢？我用的是2.2的系统测试mITelephony.endCall()没有用呀？

你可以用反射机制，把源码的文件导入的方式来实现调用

4 楼 pop1030123 2012-04-09  

这种方法拦截的话，来电时，手机界面会首先闪一下正常的来电界面的，闪动时间大概不到1秒，这样不太好。有没有从系统底层去拦截的？

AndroidManifest.xml加上来
