知识点讲解：

Android没有对外公开结束通话的API，如果需要结束通话，必须使用AIDL与电话管理服务进行通信，并调用服务中的API实现结束通话，方法如下：

1> 从Android的源代码中拷贝以下文件到项目中：
com.android.internal.telephony包下的ITelephony.aidl
android.telephony包下的NeighboringCellInfo.aidl
注意：需要在项目中建立对应的包名存放上述两个aidl文件，
如下图所示。开发工具会在gen目录下自动生成ITelephony.java

2> 调用ITelephony.endCall()结束通话：
Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);
IBinder binder = (IBinder)method.invoke(null, new Object[]{TELEPHONY_SERVICE});
ITelephony telephony = ITelephony.Stub.asInterface(binder);
telephony.endCall();

在清单文件AndroidManifest.xml中添加权限：

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

代码示例：

DemoActivity.java:

package cn.itcast.endcall;import java.lang.reflect.Method;import com.android.internal.telephony.ITelephony;import android.app.Activity;import android.os.Bundle;import android.os.IBinder;import android.os.RemoteException;import android.view.View;public class DemoActivity extends Activity {ITelephony iTelephony;/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);try {// 获取系统电话管理的服务Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);// 通过反射技术获得binder对象IBinder binder = (IBinder) method.invoke(null,new Object[] { TELEPHONY_SERVICE });iTelephony = ITelephony.Stub.asInterface(binder);} catch (Exception e) {e.printStackTrace();}}public void endcall(View view) {try {// iTelephony.endCall();iTelephony.call("15139394270");} catch (RemoteException e) {e.printStackTrace();}}}

另附NeighboringCellInfo.aidl：
