如何读取Android的特定消息格式，并存储在SQLite数据库？ [英] How to read the particular message format in android and store in sqlite database?

问题描述

正在开发一个GPS跟踪Android应用程序，我得到的GPS从客户端短信坐标。在服务器端，我需要输入短信存储在数据库中。在我的应用我得到的所有传入邮件数据库，但我只需要特定的消息格式存储在数据库中。请帮我解决这个问题。先谢谢了。

Am developing an GPS tracking android application, I get the GPS coordinates from the client side as sms. In server side i need to store the incoming sms in database. In my application i'm getting all the incoming messages to database, but i need to store only the particular message format in database. Please help me to solve this problem. Thanks in advance.

消息格式：

Lat:12.5678994
Lan:77.7847599
Accry:4.0

以上是我从客户获取消息格式，我只需要这个存储在数据库中，并非所有的传入消息。

The above is the message format which am getting from client, i need to store only this in database, not all the incoming messages.

推荐答案

您可以使用

if(messages.getMessageBody().contains("Lat:")) {

     //Write your database insertion code here

}

或

我有that..May不正确one..But还是一个解决方案..
尝试用即对于例如，一个特殊的头发送短信#####，并检查#####这样的..

I have one solution for that..May not be the correct one..But still.. Try sending the sms with a special header ie for eg "#####" and check for the "#####" like this..

if(messages.getMessageBody().contains("#####")) {

      //Write your database insertion code here

}
