Bitmap的分析与使用 关于recycle()的描述有误

hqzxzwb opened this issue · comments

虽然recycle()方法可以提前释放Bitmap占用的内存,但是不调用recycle()并不会造成内存泄漏。此方法的文档如下,注意最后一句:
Free the native object associated with this bitmap, and clear the reference to the pixel data. This will not free the pixel data synchronously; it simply allows it to be garbage collected if there are no other references. The bitmap is marked as "dead", meaning it will throw an exception if getPixels() or setPixels() is called, and will draw nothing. This operation cannot be reversed, so it should only be called if you are sure there are no further uses for the bitmap. This is an advanced call, and normally need not be called, since the normal GC process will free up this memory when there are no more references to this bitmap.
