java Android中的位图循环（）

Question

Need some help for understanding the recycle() method of the class Bitmap.

If I have a Bitmap[] named "bmp" for example whats the difference between doing

Bitmap[i].recycle()

And

Bitmap[i]=null;

Whats the best option? Should I call both?

Thanks

Answer 1

According to this question , bitmap data is stored in native memory rather than in the Dalvik heap. You should call recycle() to free the memory the bitmap is stored in once you are finished with it. It's good practice to set it to null afterwards, although this is somewhat redundant.

我认为你的意思是回收，但回收实际上是从内存中释放对象，而将其设置为null仍然会将其保留在内存中。

Android培训课程“ 有效地显示位图 ”，为理解和处理加载和回收位图提供了一些很好的信息。
