爲SIMPL的Android文檔eAdapter指出：

將數據綁定到視圖分兩個階段進行。首先，如果SimpleAdapter.ViewBinder可用，則調用setViewValue(android.view.View, Object, String)。如果返回值爲true，則發生綁定。如果返回的值是假，以下視圖然後試圖在順序：

實現可檢查（例如CheckBox）的圖。期望的綁定值是一個布爾值。
TextView。期望的綁定值是一個字符串，並且調用setViewText(TextView, String)。
ImageView。期望的綁定值是一個資源ID或一個字符串，調用setViewImage(ImageView, int)或setViewImage(ImageView, String)。

如果找不到合適的綁定，則會拋出IllegalStateException。

該適配器無法將您的jsno.getString("description")（這是一個String）轉換爲一個URL本身。您可以嘗試轉換String，然後將其作爲URL對象rssMap，但是，我建議您在綁定過程中實現自己的自定義Adapter並覆蓋getView()方法以設置WebView的URL。
