Android 对一个活动进行类膨胀时出错

我有一个活动导致我的应用程序崩溃。我不明白为什么只有这一个。我想知道这是否只是某个地方的打字错误

以下是错误：

异常堆栈的底部是一个java.lang.OutOfMemoryError，在解码ImageView中的一个图像时抛出。一般来说，你应该预计你的应用程序的内存不会超过16MB。Android的标准位图每像素使用4个字节。这意味着一张400万像素的图像将使用所有可用的RAM。检查图像，缩小过大的图像

---

如果您的图像不需要高色彩保真度，另一种选择是使用每像素仅需要2字节的不同颜色。可能有一种方法可以通过xml指定配置，但我不知道。我将在onCreate中加载位图（使用较低保真度的Bitmap.Config值），然后在ImageView上调用setImageBitmap。

java.lang.OutOfMemoryError at android.graphics.BitmapFactory

。你要加载的图片有多大？哇！3333x2500。那只是一个占位符。我把它换成了另一张图片，现在它不会崩溃耶，

位图

可能很棘手。阅读更多提示。
