Android-如何在活动运行时将最新短信添加到对话列表中?

Android-如何在活动运行时将最新短信添加到对话列表中?,android,sms,chat,contentobserver,Android,Sms,Chat,Contentobserver,我正在开发一个短信聊天应用程序。我想知道当活动像股票短信应用程序或任何其他信使一样打开时,如何在列表视图的底部添加最新的短信(发送或接收) 我尝试使用ContentObserver。只要SMS数据库中有一些更改,我就尝试用新的数据集重新加载ListView,但它不起作用。每次看到一个新的短信(发送或接收),我必须重新启动应用程序,以便列表可以重新加载。我希望这些新的信息显示在聊天窗口,只要我发送或接收他们就像我们聊天的方式,通过gtalk,msn或任何短信应用程序 这是我的密码:- public
