解决方案
你需要了解Bitmap和内存的概念
假设您想在屏幕上显示您刚刚用相机拍摄的图像.为此所需的总内存使用以下公式计算:memory_needed_in_bytes = 4 * image_width * image_height;
为什么是 4?好吧，最常见/推荐的位图配置是 ARGB_8888.这意味着对于我们绘制的每个像素，我们需要在内存中为 alpha、红色、贪婪和蓝色通道保留 8 位(1 个字节)，以便正确显示它.还有其他替代方案，例如 RGB_565 配置，它需要的内存是 ARGB_8888 的一半，但会丢失透明度和颜色精度(同时可能会添加绿色色调).
假设您拥有一台配备全高清屏幕和 12 MP 摄像头的全新设备.您刚刚拍摄的图片大小为 4000x3000 像素，显示它所需的总内存为:4 字节 * 4000 * 3000 = 48 MB
48 MB 的 RAM 仅用于单个图像！?太多了！
现在让我们考虑一下屏幕分辨率.您正在尝试在具有 1920x1080 像素的屏幕上显示 4000x3000 图像，在最坏的情况下(全屏显示图像)您不应分配超过 4 * 1920 * 1080 = 8.3 MB 的内存.
始终遵循有效显示位图的 Android 编程技巧:
测量您显示图像的视图.相应地缩放/裁剪大图像.只显示可以显示的内容.
