我只能说网上代码坑惨我了，下载的案例有的都用不来，后来研究了一下，发现也是比较简单的。唯一有点特殊的就是那个aidl文件那里，第一次接触，问了毕业 的学长知道这回事……

一； 该案例就是两个关键类TelephonyManager（获取系统的TelephonyManager管理器）和PhoneStateListener（监听电话状态的）其中的onCallStateChanged((int state, String incomingNumber))就是当电话状态改变时会回调该方法。 接下来再程序中具体介绍一下吧 在oncreat方法中

//获取系统的TelephonyManager管理器        tManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);        //获取PhoneStateListener的实例        pListener = new PhonecallListener();        //为电话管理器添加监听事件        tManager.listen(pListener, PhoneStateListener.LISTEN_CALL_STATE);

创建好这些变量

PhonecallListener为继承PhoneStateListener的内部类

//内部类，继承PhoneStateListener的子类public class PhonecallListener extends PhoneStateListener    {
           @Override        //重写的方法，当电话状态改变时调用。state为改变后的状态....        public void onCallStateChanged(int state, String incomingNumber) {            System.out.println("监听开始");            switch(state)            {            case TelephonyManager.CALL_STATE_IDLE:break;            case TelephonyManager.CALL_STATE_OFFHOOK:break;            //当有电话拨入时            case TelephonyManager.CALL_STATE_RINGING:                System.out.println("来电");                if(isBlock(incomingNumber))                {                    System.out.println("挂电");                    try                    {                        //反射                        Method method = Class.forName("android.os.ServiceManager")                                .getMethod("getService", String.class);                        // 获取远程TELEPHONY_SERVICE的IBinder对象的代理                        IBinder binder = (IBinder) method.invoke(null,                            new Object[] { TELEPHONY_SERVICE });                        // 将IBinder对象的代理转换为ITelephony对象                        ITelephony telephony = ITelephony.Stub.asInterface(binder);                        // 挂断电话                        telephony.endCall();                        System.out.println("挂断成功");                    }catch(Exception e){e.printStackTrace();}                }                break;            }            super.onCallStateChanged(state, incomingNumber);        }    }

类的分布图

注意这个两个aidl文件以及所在的包 NeighboringCellInfo文件必须位于android.telephony;包中 其内容为

package android.telephony;parcelable NeighboringCellInfo;

ITelephony文件必须位于com.android.internal.telephony包中

其内容为

在eclipse中添加aidl文件的方法

先在这个包中新建.java然后到工作所在文件文件夹中吧java的后缀改成aidl即可.

还有一个重要的就是传限permission
