Android收发短信

满堂花醉三千客，一剑霜寒十四州。这篇文章主要讲述Android收发短信相关的知识，希望能为你提供帮助。
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【Android收发短信】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
