Question

我正在尝试滑动刷新。但是，一旦加载了rss feed，刷新视图就会出现一个片段。此代码不会使应用程序崩溃，但刷新视图会无限期保留，并且不会采用我提供的任何属性。

View v = getLayoutInflater().inflate(R.layout.fragment_rss, null);
SwipeRefreshLayout refresh = (SwipeRefreshLayout) 
v.findViewById(R.id.swiperefresh);
refresh.setEnabled(true);
refresh.setColorSchemeColors(getResources().getColor(R.color.colorAccent), 
     getResources().getColor(R.color.colorPrimary), 
     getResources().getColor(R.color.white));
refresh.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() 
    {
    @Override
    public void onRefresh() {
        new refresh().execute("");
    }
});

new refresh().execute("");调用异步动画，然后在动画完成后调用refresh方法。

private class refresh extends AsyncTask<String, Void, String> {

    @Override
    protected String doInBackground(String... params) {
        try {
            Thread.sleep(500);
        } catch (InterruptedException e) {
            return "Interrupted";
        }
        return "Executed";
    }

    @Override
    protected void onPostExecute(String result) {
        refreshRssFragment();
    }
}

这是XML

<android.support.v4.widget.SwipeRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/swiperefresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView
        android:visibility="gone"
        android:id="@+id/newsList"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true">
    </ListView>

</android.support.v4.widget.SwipeRefreshLayout>

这是refreshRssFragment（）方法

 private void refreshRssFragment(){
    FragmentManager manager = getSupportFragmentManager();
    FragmentTransaction transaction = manager.beginTransaction();
    RssFragment fragment = new RssFragment();
    transaction.replace(R.id.fragment_container, fragment);
    transaction.commit();
    refresh.setRefreshing(false);
}`

使用不是当前视图的视图实现SwipeRefreshLayout
