android - 当listview加载有数据android时，将imageview对齐到listview的末尾

我正在设计一个具有自定义布局的自定义列表视图。因为在完成从Web服务加载数据的列表视图后，我需要在列表视图的末尾和@+id/progressBar1上方添加一个Imageview。

在这种情况下，不能使用listview.addFooterView(View v)，因为我使用了来自第三方库Pull to refresh listview的自定义PullToRefreshListview

}

最佳答案

尝试更改此代码：

 View footer_image=inflater.inflate(R.layout.listview_image_footer, container,false);

有了这个 ：

 View footer_image=inflater.inflate(R.layout.listview_image_footer,null);

注意：这里的容器是引用片段xml，尝试将自定义页脚添加到包含在容器中的ListView中，因此将页脚的根值设置为null而不是容器
