您好我正在使用以下链接开发一个应用程序 Custom ListView With Headers

现在我的问题是我想将图像设置为listview的标题。我使用第二种类型的addsection显示项目列表，即; 

adapter.addSection("Security", new SimpleAdapter(this, security, R.layout.list_complex,  
            new String[] { ITEM_TITLE, ITEM_CAPTION }, new int[] { R.id.list_complex_title, R.id.list_complex_caption }));

我在list_headre.xml.at中使用图像视图而不是textview，那时我得到以下异常

现在我想将图像显示为标题而不是TextView。为此，请给我一些代码建议。谢谢提前

答案 0 :(得分：2)

ArrayAdapter仅支持TextView次观看。 As per the docs：要使用TextViews以外的其他内容来显示数组，例如ImageViews，或者除了toString（）之外还有一些数据填充视图，覆盖getView（int，View，ViewGroup）返回您想要的视图类型。

如果您只想在标题中添加一个ImageView，我会使用下面的原始答案。

原始回答：使用ListView中的方法addHeaderView，然后传递ImageView。
