如何在同一屏幕上使用大量ImageView
?
我的活动屏幕:
我有这种类型的布局,每张图片都是单独的ImageView
。
在某些设备上它会抛出OutOfMemoryError
,但是这些设备可以完美地运行。
其中一个"解决方案"我在堆栈上找到了:
将所有可绘制文件夹内容复制到drawable-xhdpi,drawable-xxhdpi等等,有一段时间它没有给出OutOfMemoryError
个错误。但是,它将我的应用程序的总大小增加了几MB。
我不确定位图处理方法。
这是我的布局代码:

使用Glide库在图像视图中加载图像。
Glide是一种快速高效的开源媒体管理和图像 Android的加载框架包装媒体解码,内存和 磁盘缓存,资源池化成简单易用 接口
您可以使用下面的Glide
Glide.with(fragment)
.load(url)
.into(imageView);
