Question

在我的android项目中，有自定义网格视图和图像。图像来自资产文件夹。

这是从资产文件夹获取drawable的代码：

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

滚动网格视图后，它会给出内存不足异常日志显示：

Answer 1

根据我的经验，这通常是因为你在其他地方有内存泄漏，然后你的应用程序可能会在任何地方呱呱叫，但在位图操作期间最有可能耗尽内存。

Answer 2

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

这消耗更少的内存：

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

大于

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

android - 从资产中获取drawable时的内存不足异常
