在我的 android 项目中，有带有图像的自定义网格视图。图片来自资产文件夹。

这是从资产文件夹获取可绘制的代码：

Drawable imgDrawable = Drawable.createFromStream(myContext.getAssets().open(imgPath),null);

滚动网格视图后，它给出内存异常日志显示：

以我的经验，这通常是因为您在其他地方有内存泄漏，然后您的应用程序可能会在任何地方发牢骚，但最有可能在位图操作期间耗尽内存。

我遇到了同样的问题。然后我决定尝试使用 Bitmaps 而不是 Drawables，我不再收到 OutOfMemoryException 了。

这消耗更少的内存：

view.setImageBitmap( BitmapFactory.decodeFile( filename ) );

比

view.setImageDrawable( Drawable.createFromPath( filename ) );
