为何奇怪？虽然定制的应用程序在HTC One和HTC One X上都经过测试，但它们都表现良好，只有内存问题（HTC One X）。但是，当我在三星Galaxy S上测试这个应用程序时，它会加载所有内容，甚至是第二个菜单，但不会更进一步......任何想法？ Java文件：

答案 0 :(得分：2)
三星Galaxy S是一款旧设备（4年前制造），只有512 MB的RAM可用，而HTC One X / One是更新的手机，提供1GB / 2GB的RAM。所以你的问题是你试图同时加载21张图片（它们是XML的硬编码），这就是你得到OutOfMemoryError的原因。他们确实会一起展示吗？我建议您以编程方式为ImageViews设置图像，当它们真正需要时 - 延迟加载。您可以通过使用Picasso
