通过aidl及反射实现挂断电话

具体分三步：

(1)ITelephony.aidl ,必须新建com.Android.internal.telephony包并放入ITelephony.aidl文件(构建后在gen下有ITelephony.java文件，这是aidl生成的接口)，文件内容如下：

package com.android.internal.telephony;

interface ITelephony{

boolean endCall();

void answerRingingCall();

}

(2)在需要的类中添加如下方法,代码如下(通过反射获取电话接口的实例)

/**

* @param context

* @return

*/

private static ITelephony getITelephony(Context context) {

TelephonyManager mTelephonyManager = (TelephonyManager) context

.getSystemService(TELEPHONY_SERVICE);

Class c = TelephonyManager.class;

Method getITelephonyMethod = null;

try {

getITelephonyMethod = c.getDeclaredMethod("getITelephony",

(Class[]) null); // 获取声明的方法

getITelephonyMethod.setAccessible(true);

} catch (SecurityException e) {

e.printStackTrace();

} catch (NoSuchMethodException e) {

e.printStackTrace();

}

try {

ITelephony iTelephony = (ITelephony) getITelephonyMethod.invoke(

mTelephonyManager, (Object[]) null); // 获取实例

return iTelephony;

} catch (Exception e) {

e.printStackTrace();

}

return iTelephony;

}

(3)在来电时调用此实例，然后调用此endCall()方法。

mTelephonyManager = (TelephonyManager) this

.getSystemService(TELEPHONY_SERVICE);

mTelephonyManager.listen(phoneStateListener,

PhoneStateListener.LISTEN_CALL_STATE);

//电话实例

PhoneStateListener phoneStateListener = new PhoneStateListener() {

@Override

public void onCallStateChanged(int state, String incomingNumber) {

switch (state) {

case TelephonyManager.CALL_STATE_RINGING :

iTelephony = getITelephony(getApplicationContext()); //获取电话接口

if (iTelephony != null) {

try {

iTelephony.endCall(); // 挂断电话

Toast.makeText(getApplicationContext(),

"endCall "+ incomingNumber +"  successful!", 3000).show();

} catch (RemoteException e) {

e.printStackTrace();

}

}

break;

default :

break;

}

}

};
