Android的EdgeEffect似乎分配1兆位图 [英] Android EdgeEffect appears to allocate a 1 meg bitmap

问题描述

我们正在运行内存分析工具在我们的应用程序来优化它。我们注意到，它总是标志的大型1127584字节位图作为一个可能的内存泄漏。

We were running Memory Analyzer Tool in our application to optimize it. We noticed that it always flags a large 1,127,584 byte Bitmap as a possible memory leak.

在分析过程中，我们意识到它无关，与我们的应用程序，只是创造与任何包含滚动部件会显示相同的结果显示在屏幕快照，标志图中单个布局一个简单的项目。

During analysis, we realized that it has nothing to do with our app and just creating a simple project with a single layout that contains any scrollable widget will show the same results as shown in the screenshot which flags the Bitmap.

问题是 - 任何人都知道这个形象是和我们应该用它担心

Question is -- anyone know what this image is for and should we be concerned with it?

推荐答案

这是一个迟到的答案，但也许这将帮助别人，我有一个类似的问题，我见过一些大的位图服用相对大量的内存，在Android工作室堆转储，我发现它从滚动视图，所以我已经添加了这个属性的XML来禁用滚动视图效果，我不再看到堆转储该分配。

this is a late answer but maybe this will help others,I had a similar issue i've seen some big bitmap taking relatively a lot memory in the android studio heap dump, i found out it came from the scrollview so I've added this attribute to the xml to disable the scrollview effects and i dont see this allocation anymore in the heap dump.

安卓overScrollMode =从不

android:overScrollMode="never"

P.S
我现在可以看到在微调DropDownListVew，当它开启了同样的问题堆转储

p.s I can see now in the heap dump that the spinner DropDownListVew, when its opened has the same issue
