如何獲取包含XML標籤Android Studio的內部圖像url？

我無法訪問內部標記，以獲取圖像「url」在這裏我的標記名稱是「enclosure」，它包含另一個名爲「url」，這就是我想要得到的... here一整節課，我創建如何獲取包含XML標籤Android Studio的內部圖像url？

您可以發佈XML響應也或格式？ – curiousMind

我建議打印原始數據並查看標籤的層次結構。只是做一個日誌而不分析數據並自己閱讀。它可能會丟失，或者您在獲取之前需要訪問父標籤。

這也許看起來很基本，但你確定你輸入正確嗎？（大寫字母，空格等）

其他標籤怎麼樣？我想你正確地得到它們。

我輸入正確.. –

你得到什麼迴應（原始數據）？ –

解決只有兩個LINES

else if ("enclosure".equalsIgnoreCase(tagName)) { 
           String url = xxp.getAttributeValue(0); 
           currentNews.setImageUrl(url); 
          }
