Question

我正在使用这种布局，这似乎会导致内存问题。我重新调整按钮的大小，使其与Program中的屏幕完全匹配。引入屏幕的一小部分动画似乎足以引起问题。图形不是很大，所以它必须是导致问题的大量按钮？

也许我最好创建一个大图像/按钮并根据他们点击的图像中的坐标激活选项/按钮。

aa.png，bb.png等只有64px乘64px，单个“左”图像是240px乘240px

Answer 1

嗯，也许这不是你预期的优化内存使用的答案，因为你不发布你的任何代码（只有布局），但是这个hack会把你的内存堆增加到最大值。将此配置android:largeHeap="true"添加到清单中的应用程序上下文中。

Answer 2

您的布局未导致OOM错误。布局看起来很好。

您可能在游戏/应用中分配了太多内存。检查您的代码，看看您的位图/绘图如何分配和使用，或在此处发布您的代码供我们查看。

如果要调试内存的分配方式，请点击以下链接： https://developer.android.com/tools/debugging/debugging-memory.html

这些抽屉是什么aa，bb，cc ....等
它们的大小是什么？
您在哪个文件夹中放置了它们？
您使用的是什么设备？

Answer 3

似乎错误的原因是你的绘图。您应该尝试使用一些可以为您处理图像缓存的第三方库。一个例子是Picasso。这是一个非常好的图像库，易于使用。
