向PullToRefreshListView添加页脚：获取ClassCastException

时间：2014-07-01 10:16:45

标签： android footer pull-to-refresh

这是我的问题：

    private PullToRefreshListView listView_;
    public void onActivityCreated(Bundle savedInstanceState)
    {
       listView_ = (PullToRefreshListView) view_.findViewById(R.id.lista_tuoivincoli_refresh);
       LayoutInflater inflater = (LayoutInflater) context_.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                    LinearLayout listViewFooter = (LinearLayout) inflater.inflate(R.layout.contodeposito_tuoivincoli_tabella_vincoli_footer, listView_, false);
                    ListView tempView = listView_.getRefreshableView();
                    tempView.addFooterView(listViewFooter);

...
}

我在这个列表中，里面有一些信息。在页脚中，我得到数字并显示总数。 首先，listView_是一个简单的ListView，而且每个方面都很有效。 将我的xml更改为：

<com.handmark.pulltorefresh.library.PullToRefreshListView
            android:id="@+id/lista_tuoivincoli_refresh"
            android:layout_width="360dp"
            android:layout_height="300dp"
            android:layout_marginTop="6dp"
            android:divider="@android:color/transparent"
            android:dividerHeight="6dp"
            android:fadingEdge="none"
            android:fastScrollEnabled="false"
            android:footerDividersEnabled="false"
            android:headerDividersEnabled="false"
            android:smoothScrollbar="true" />

将第一行从ListView更改为＆＃34; com.handmark.pulltorefresh ....＆＃34; 并添加最后5行（由pulltorefresh库使用。

如果我评论该行

tempView.addFooterView(listViewFooter);

项目运作完美，刷新也有效。

我尝试添加一个带有Handler的postDelayed：

new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {

                LayoutInflater inflater = (LayoutInflater) context_.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                LinearLayout listViewFooter = (LinearLayout) inflater.inflate(R.layout.contodeposito_tuoivincoli_tabella_vincoli_footer, listView_, false);
                ListView tempView = listView_.getRefreshableView();
                tempView.addFooterView(listViewFooter);
            }
        }, 3000);

但这不起作用。

我看到的其他问题（我看到很多）建议使用getRefreshableView（），但我已经使用过了。

当他给页脚充气时项目崩溃。

谢谢！

答案 0 :(得分：2)

请将listView_替换为tempView。可能它应该工作

new Handler().postDelayed(new Runnable() {

    @Override
    public void run() {

        ListView tempView = listView_.getRefreshableView();
        LayoutInflater inflater = (LayoutInflater) context_.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        LinearLayout listViewFooter = (LinearLayout) inflater.inflate(R.layout.contodeposito_tuoivincoli_tabella_vincoli_footer, **tempView**, false);

        tempView.addFooterView(listViewFooter);
    }
}, 3000);
