推荐答案

您无法从imageview获取图片网址...事实上，您将不得不使用备用网址.例如，您可能将imageview的网址保存在某个数组中...您需要获取被单击的imageview的位置，并使用该位置可以获取被点击的图像的url ...如果您使用listview/gridview来获取它获取位置非常容易，但是如果没有，您可以将pos设置为图像标签，然后检索将指定位置的标签.

u cannot get the image url from the imageview...infact u will have to use the alternate. For example u might be saving the urls for the imageview in some array...u need to get the position of the imageview clicked and using that position u can get the url of the clicked image...if u r using listview/gridview it is very easy to get the position but if not, u can set the pos as tag of image and retrieve the tag that will specify the position.
