android - 在 android 中拉取 ListView 时刷新适配器

Question

如何应用下拉ListView的效果，释放时会刷新。 和Facebook一样，下拉时会刷新NewsFeeds。

Answer 1

您可以使用 this用于在 android 中创建此类列表。

您必须在代码中使用刷新监听器:

   PullToRefreshListView listView = (PullToRefreshListView) findViewById(R.id.pull_to_refresh_listview);
   listView.setOnRefreshListener(new OnRefreshListener() {


public void onRefresh() {
    // Your code to refresh the list contents

    // ...

    // Make sure you call listView.onRefreshComplete()
    // when the loading is done. This can be done from here or any
    // other place, like on a broadcast receive from your loading
    // service or the onPostExecute of your AsyncTask.

    listView.onRefreshComplete();
}
});
