的一系列圖像
我試圖找到yout,從此鏈接顯示一組圖像的方式是www.repubblica.it/rss/tecnologia/rss2.0.xml
。我必須在我的RSS應用程序中顯示它們,但我堅持這一論點。 圖片在這個標籤<enclosure url="http://www.repstatic.it/content/nazionale/img/2014/02/06/201914230-3e1f0f4a-c5e4-413a-acd0-f15b781438eb.jpg" length="24317" type="image/jpeg"/>
(例如)。 你能幫我嗎?任何幫助表示讚賞。 這是我Handler

關於如何展示他們?我必須添加 _final int state_enclosure_和_public vois chatacter()_方法添加此: _case state_enclosure: item.setEnclosure(strCharacters); break; _; case state_title: feed.setTitle(strCharacters); 休息; – Pier
如果你只需要你不需要的URL實現chatacter(),你會從startElement方法 中的url中獲得值,你需要將它保存在數組中,解析後下載它們,你可以在你的視圖中顯示它們,你用state_enclosure表示什麼? –
沒什麼,我很困惑。那麼爲了在我的ArrayAdapter中展示它們,這代碼很好嗎? – Pier
