前几天我也在做处理图片导致内存溢出，后来找了个图片缓存的开源库希望对你有帮助 https://github.com/square/picasso

这段代码好像不用老是new bitmap，如果是模拟器的话，bitmap多了，内存溢出是很正常的，而且你还是在getview这个方法里，如果列表数据多了，你的bitmap会越来越多，从你的代码看，图片是存在drawable里的，把bitmap删掉，需要显示图片时就setBackgroundResource（），千万别过多使用bitmap。非常占内存

up 不过频繁setBackgroundResource也不太好，会导致频繁gc回收的吧

mBgBitmap2 = minBitmap( R.drawable.null_room); 我不知道你对图片做了什么操作，但是估计是把图片变小，这个东西可以叫ux 给你一个图片即可，不要在代码里面操作， list 滑动时岂不是很慢，个人建议
