我使用畢加索來加載從webservice解析的幾個圖像...問題是,我有多個項目,但只有最後一個項目被下載並加載到所需的視圖...這裏是我的代碼的一部分處理該填充物品:畢加索for循環加載只有一個圖像
public void populate_jobs(ArrayList<RowItem> jobs)
{

RowItem item_second = null;

我打電話的這個在我的AsyncTask的onPostExecute功能,它負責從web服務獲取JSON數據循環的功能。所有圖像的圖像源內容都是正確的,可以通過瀏覽器訪問,原因可能是什麼?在此先感謝
編輯:因爲我檢查它似乎只加載1特定圖像,而不是最後一個。
請發送完整代碼 –
+1。您需要發佈循環的完整代碼。 – greenapps
已更新並添加了整個功能,它已在onPostExecute中調用 –
