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
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
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="挂断电话"
android:onClick="endCall"/>
</RelativeLayout>
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
<!-- 结束通话和打电话的权限 -->
<uses-permission android:name="android.permission.CALL_PHONE"/>
