在Android对话框中显示URL中的图像
[英]Displaying a image from a URL in Android dialog
问题描述
How would one go about displaying an image in the Android Dialog that is retrieved from the internet from a URL? 
如何在Android对话框中显示从URL从Internet检索的图像？ I have seen examples of Dialogs with pictures (like here: http://quickandroid.blogspot.com/2011/03/alert-dialog-with-list-of-text-and.html ) but all that I saw is how the piture is retrieved from the drawable folder. 我已经看到了带有图片的对话框示例（例如此处： http : //quickandroid.blogspot.com/2011/03/alert-dialog-with-list-of-text-and.html ），但是我所看到的只是从可绘制文件夹中检索piture。
How to display the image in a dialog from a URL? 如何通过URL在对话框中显示图像？ Is dialog even the best choice? 对话甚至是最佳选择吗？ Should I download the image first? 我应该先下载图像吗？
Thank you :) 谢谢 ：）

Universal Image Loader is a good tip. Universal Image Loader是一个很好的技巧。 No need to download the picture yourself. 无需自己下载图片。 You can first download the picture with UIL, then inflate a Dialog from a layout (needs only contain an ImageView) and show the dialog. 您可以先使用UIL下载图片，然后从布局中添加一个Dialog （只需要包含一个ImageView），然后显示该对话框。 Or you can extend DialogFragment , download the picture and show it from there. 或者，您可以扩展DialogFragment ，下载图片并从那里显示。 If a dialog is the best way to show a picture is up to you and your app. 如果对话框是显示图片的最佳方式，则取决于您和您的应用。
