Android：由OutOfMemoryError引起的类<unknown>错误：位图大小超过VM预算</unknown>

标签： android imageview

我有一个错误，似乎是由Bitmap引起的类错误（这里有更多细节：Android: Memory error because of an ImageView?）但是当我对位图发表评论时，我仍然有错误，而当我评论Imageview5时，没有错误。有关此错误的stackoverflow上的所有帖子都没有帮助解决我的问题

我的第23行是imageview5 

   <ImageView
         android:id="@+id/imageView5"
         android:layout_width="85dp"
         android:layout_height="100dp"
         android:layout_marginLeft="8dp"
         android:layout_marginTop="20dp"
         android:adjustViewBounds="true"
         android:src="@drawable/diviseur" />

答案 0 :(得分：5)

这是一个非常误导性的错误，但它是由嵌套异常引起的，因为VM已经耗尽了可绘制的diviseur的内存。请参阅堆栈跟踪的结尾：

答案 1 :(得分：1)

有时可能会发生这种情况，最佳做法是使用位图工厂创建缩放位图

Bitmap result = Bitmap.createScaledBitmap(bitmapPicture,
                    imageWidth, imageHeight, false);

试试这个，看看是否有帮助

也可以使用，

BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inPurgeable = true; // Tell to garbage collector that whether it needs free memory, the Bitmap can be cleared
opts.inTempStorage = new byte[32 * 1024];

并在离开该活动时始终回收您的位图，因为它有助于释放内存。

希望这有帮助

答案 2 :(得分：1)

我得到了同样的错误。我的问题是每部手机都装载了2k图像作为活动的背景。我通过将此背景图像缩小到800x480和1280x720来解决了这个问题。然后我将这些图像放入ldpi，mdpi，...文件夹中。现在它可以正常工作
