Android Sms阅读

Question

我正在开发一款读取短信的应用。我已经把它读成历史性的，但当一个新的到来时，它不会出现，直到我关闭应用程序并再次打开它...就像它没有自己刷新列表视图...

我确实尝试过这些代码...还有更多，但没有人工作..

的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.reading.smsreading">

            final Object[] pdusObj = (Object[]) bundle.get("pdus");
