前些天发现了一个巨牛的人工智能学习网站，通俗易懂，风趣幽默，忍不住分享一下给大家。[点击跳转到教程][Link 1]  
android没有相关API挂断电话，而是使用AIDL，使用ITelephony的endCall()  
首先项目中引入ITelephony.aidl，注意报名需要跟文件定义的一致

在项目中我们为了测试该功能，当有电话的时候，我们点击一个按钮，来手工挂断电话。布局如下  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5nYmFva2FuZw_size_16_color_FFFFFF_t_70]

处理Activity类

package com.hbk.remoteservice;
    
    import java.lang.reflect.Method;
    
    import android.app.Activity;
    import android.content.Context;
    import android.os.Bundle;
    import android.os.IBinder;
    import android.view.View;
    
    import com.android.internal.telephony.ITelephony;
    
    public class MainActivity extends Activity { 
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) { 
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    	}
    	
    	public void endCall(View v) throws Exception { 
    		//通过反射调用隐藏的API
    			//得到隐藏类的Class对象
    		Class c = Class.forName("android.os.ServiceManager");
    			//得到方法所对应的Method对象
    		Method method = c.getMethod("getService", String.class);
    			//调用方法
    		IBinder iBinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE);
    		//得到接口对象
    		ITelephony telephony = ITelephony.Stub.asInterface(iBinder);
    		//结束通话
    		telephony.endCall();
    	}
    }

我们需要通过反射去加载ServiceManager，调用方法得到IBinder对象  
在清单文件中增加如下权限

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