Question

I have an ASync task that D/L the images for the list view. Have the listview and the listview adapter implementation working fine.

My question is: After D/L the images from the web... 1. Should I save it into a temporary directory and load it from there? OR 2. Should I keep it in memory? But in this case might consume lots of memory since the list size can be big. 3. If I have an image that was U/L before to the server, I need to show it in the listview as a small image (sample?). Should I jsut put the image in the imageview? Should I process the image and scale it?

我会把图像保存在一张黑白中。这意味着,如果监督厅记忆不佳,就会释放这些图像。此外,你可以将其留给SD卡,这样,当图像必须重载时,图像就会更快。 https://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-inlistview” 清单中一些新内容的图像装载量。

大力建议对图像进行增量。
