【参考方案1】：

如果您在运行时加载位图，您可以在使用this technique 从设备读取它时将其缩小。如果您从res 目录加载它，您可能只需要使用图像编辑器将其缩小。无论哪种方式，图像显然都太大而无法放入内存。

【参考方案2】：

如我所见，您使用ImageView.setImageURI 加载图像。

现在许多图像，尤其是由更高分辨率的相机（或手机）拍摄的图像，很容易占用比在屏幕上显示它们实际需要的空间更多的空间。

当您尝试将它们直接加载到位图中时，您的应用将耗尽内存并崩溃。 另请参阅此question 或@oakleaf 的答案，以获取有关使用大型位图的 Android 开发人员培训链接。
