ImageAdapter和ListView（java.lang.OutOfMemoryError：位图大小超过VM预算） [英] ImageAdapter and ListView (java.lang.OutOfMemoryError: bitmap size exceeds VM budget)

问题描述

我使用ListView控件来显示我通过ImageAdapter类提供的图像。 它的伟大工程我的设备上（和我测试了许多其他设备），但不知何故，当我使用模拟器，我长期pressing上/下按钮 - 我发现了一个内存不足10-15秒后错误。

I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds.

我试图清除缓存，取消缓存，等等 - 没有任何帮助

I tried clearing cache, canceling cache, etc. - nothing helped.

我知道这崩溃是pretty的罕见的（我不能复制它的任何真正的设备），但我可以在DDMS看到，全球契约中解脱出来的规模越来越大时，长期preSS和我无法找到一个方法来清除它们。

I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them.

任何帮助将AP preciated，TNX。

Any help will be appreciated, Tnx.

推荐答案

您应该取消code与inSampleSize选项，以减少内存消耗。 <一href="http://stackoverflow.com/questions/477572/android-strange-out-of-memory-issue/823966#823966">http://stackoverflow.com/questions/477572/android-strange-out-of-memory-issue/823966#823966

You should decode with inSampleSize option to reduce memory consumption. http://stackoverflow.com/questions/477572/android-strange-out-of-memory-issue/823966#823966

另一种选择inJustDe codeBounds可以帮助你找到正确的inSampleSize值的http://groups.google.com/group/android-developers/browse_thread/thread/bd858a63563a6d4a

Another option inJustDecodeBounds can help you to find correct inSampleSize value http://groups.google.com/group/android-developers/browse_thread/thread/bd858a63563a6d4a

您也应该考虑使用inPurgeable选项<一href="http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inPurgeable" rel="nofollow">http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inPurgeable.它可以让系统来释放你的记忆，以避免内存不足。

You should also consider using inPurgeable option http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inPurgeable. It allows system to free your memory to avoid OutOfMemory.
