如何将下载的图像存储在缓存中

Question

I'm working on a Syllabus application for my project in Android which shows a list of subjects in a RecyclerView . When clicked on a subject, it downloads the image from its URL and displays it in the ImageView . I need a code which stores the Image in cache once it is downloaded, so the user doesn't need to download the image from the URL again and again.

Answer 1

For downloading images, you can use Glide library. This library lets you download the image efficiently and cache them also so you don't have to manually do it.

Answer 2

Use Picasso library. Reference - https://guides.codepath.com/android/Displaying-Images-with-the-Picasso-Library

Answer 3

如果您有很多图像要加载到您的应用程序中，我会提供使用外部存储而不是缓存，因为如果您的应用程序缓存已满，android会删除所有应用程序缓存
