位图大小是否超过VM budget...how以解决此错误？

Question

我已经看了这么多关于这个错误的帖子，但没有得到我的问题的适当解决方案。在我的projec..in中有三个活动，每个活动有四个我使用序列的动画。在onclick更改我的活动时，我收到vm预算内存不足错误。当我们要进行其他活动时，如何清除记忆中的活动？这样内存就可以用于下一次活动。提前感谢你的帮助……

错误发生如下所示...

Answer 1

你必须像下面这样缩放你的位图，

img.setImageBitmap(Bitmap.createScaledBitmap(bitmap, 200,200, true));

那么它的大小将不会exceed.It固定到一个特定的大小。
