我想知道在视图中使用图像绘制文件时如何将它们加载到内存中。
我的问题是我有一个大尺寸的图像（约600x700），仅重4kb。我认为没有必要创建一个9补丁图像，因为图像足够小。但是，当我尝试将此图像用作背景时，Android会给我内存错误。

我添加了其他大图像作为背景没有问题，我怀疑我的应用程序占用了除4kb以外的所有内存空间，因为其他活动加载了比这个更多的资源，我可以轻松访问它们。
我应该考虑其他方面而不是最终图像字节大小吗？
答案 0 :(得分：0)
Bitmap未压缩，600x700尺寸使内存非常大，如果质量不是问题，可以尝试将其缩小。
编辑：
600 * 700 * 32/8 = 1680000
