iTelephoneManager学习

本文程序演示了以下功能：

1.所有来电自动接听；

2.所有来电自动挂断；

3.开启/关闭Radio；

4.开启/关闭数据连接(WAP or NET的连接)。

调用TelephonyManager的隐藏API是先参考Framework的\base\telephony\java\com\android\internal\telephony\ITelephony.aidl，然后自己实现一个ITelephony.aidl，最后在TelephonyManager中通过反射机制实例化自定义的ITelephony，实例化之后就可以调用ITelephony里面的函数了。

本文程序需要在AndroidManifest.xml添加以下两行代码，以获得权限：
Xml代码 
<uses-permission android:name="android.permission.CALL_PHONE" />    
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />   

<uses-permission android:name="android.permission.CALL_PHONE" /> 
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /> 

main.xml源码如下：
Xml代码

PhoneUtils.java是手机功能类，从TelephonyManager中实例化ITelephony并返回，源码如下：

    static public ITelephony getITelephony(TelephonyManager telMgr) throws Exception {    
        Method getITelephonyMethod = telMgr.getClass().getDeclaredMethod("getITelephony");    
        getITelephonyMethod.setAccessible(true);//私有化函数也能使用    
        return (ITelephony)getITelephonyMethod.invoke(telMgr);    
    }    
        
    static public void printAllInform(Class clsShow) {      
        try {      
            // 取得所有方法      
            Method[] hideMethod = clsShow.getDeclaredMethods();      
            int i = 0;      
            for (; i < hideMethod.length; i++) {      
                Log.e("method name", hideMethod[i].getName());      
            }

    }
