使用ImageView的OutOfMemory错误 [英] OutOfMemory Error using ImageView
本文介绍了使用ImageView的OutOfMemory错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图使使用ImageView的壁纸集的应用程序。我知道它很难显示一些图片（尤其是当图像是1920×1080），我所做的就是让其他许多使用，将被显示在应用程序中一个较小的分辨率（400x200）的图片，但是当用户试图设置一张照片作为墙纸它得到相同的图像，但具有更大的分辨率。
我认为这将解决我的问题，但它并没有，应用程序，然后运行之前有更多的时间，但在目前它失败。我注意到，当我设置3图像作为壁纸应用程序失败。我try'd使用垃圾收集，这是行不通的。任何想法？

解决方案
移动图像，以一个名为绘-nodpi新文件夹。
原因
在不同的文件夹中绘制的图像是由不同的内存分配android系统的开通，华电国际表示将采取的记忆有很多即使图像是微小的。
绘-nodpi是最好的记忆保存。
i'm trying to make a wallpaper set app using ImageView. I know its hard to display a bunch of images (especially when images are 1920x1080), what i did was to make other bunch of images with a smaller resolution (400x200) that would be displayed in the app, but when user is trying to set a image as wallpaper it gets the same image but with the bigger resolution. I thought this will solve my problem, but it didn't, the app runs more time then before, but at a moment it fails. I noticed that the app fails after i set 3 images as wallpaper. I try'd to use garbage collector, it doesn't work. Any ideas?
Here is my code.

解决方案
Move the images to a new folder called "drawable-nodpi".
Reason
Images in different drawable folders are opened by the android system with different memory allocations, hdpi means it will take a LOT of memory even if the image is tiny.
drawable-nodpi is the best for memory saving.
