Android收发短信

Posted 2020-10-08 AYE89

效果：点击发送短信开始发送短信

           收到短信时将短信的内容显示出来

代码如下：

一、权限声明

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

二、代码实现

我们的短信功能用到了SmsManager和SmsMessage两个主要类。

当收不到短信时候，手动在应用管理中将应用的短信收发权限打开　　

//Java
/** 
 * Created by Linda on 16/5/14. 
 * 短信的收发 
 * 根绝国际标准 每条短信的长度不超过160 个字符 
 * 如果短信长度过长，可以调用sendMultipartTextMessage()分隔成多条短信来发送
