Android错误位图超出VM预算

标签： android memory stack-trace

我编写了一个简单的应用程序，可以从scrollview中加载多个壁纸（20）并允许用户将它们设置为他/她的背景。它在我的设备上安装并正常工作，但用户在安装后立即报告“强制关闭”错误，这根本不允许他们打开应用程序！我收到的唯一报告的错误是这个OutOfMemory错误，但它非常神秘，我不确定是什么问题！任何指导都将不胜感激，谢谢！

1 个答案:

答案 0 :(得分：0)

这是非常糟糕的代码片段。您应该知道您的应用程序在设备上只有一小部分内存，因此您无法一次在内存中加载所有Bitmap内容。

  1. 使用GridView，ListView而不是拥有大量ImageView。
  2. 将位图质量降低到合理的质量，或者您可以缩放它们。
  3. 我可以看到你正在尝试写一些用户可以从图像列表中选择的内容设置为WALLPAPER;我推荐Gallery。
