我用 json 创建 Rss，当我从后台获取 jsonObject 时，在 postExecute 我用对象结果创建 Map，然后我有一个错误 LogCat 在 SimpleAdapter 中导致错误 WebView 为什么，没有人可以帮忙？

SimpleAdapter 的 Android 文档指出：

将数据绑定到视图分两个阶段进行。首先，如果 SimpleAdapter.ViewBinder 可用，setViewValue(android.view.View, Object, String)则调用。如果返回值为true，则表示发生了绑定。如果返回值为 false，则依次尝试以下视图：

  • 实现 Checkable 的视图（例如CheckBox）。预期的绑定值是一个布尔值。
  • TextView. 预期的绑定值是一个字符串并被setViewText(TextView, String)调用。
  • ImageView. 预期的绑定值是资源 id 或字符串，并且setViewImage(ImageView, int)或被setViewImage(ImageView, String)调用。

如果找不到合适的绑定，则抛出 IllegalStateException。

适配器无法自行将您的jsno.getString("description")（即 a String）转换为 URL。您可以尝试转换字符串，然后将其作为 URL 对象放入 中rssMap，但是，我建议您实现自己的自定义Adapter和覆盖方法来设置绑定期间getView()的 URL 。WebView
