很多人在android开发中都遇到了生成bitmap时候内存溢出,也就是out of memory(OOM)的问题,网上对这样的问题的的解决说法不一.笔者作为一个初级开发者,在这里向大家提供一种比较实用,比较易于理解的方法,这种方法不如一些高级开发者提出的方案来的深刻,但是也能帮助大家有效地解决问题.废话不多说了,直接上代码. BitmapFactory.Options opt = new BitmapFactory.Options(); //这个isjustdecodebounds很重要 op

1.Redis中key的的过期时间 通过EXPIRE key seconds命令来设置数据的过期时间.返回1表明设置成功,返回0表明key不存在或者不能成功设置过期时间.在key上设置了过期时间后key将在指定的秒数后被自动删除.被指定了过期时间的key在Redis中被称为是不稳定的. 当key被DEL命令删除或者被SET.GETSET命令重置后与之关联的过期时间会被清除 127.0.0.1:6379> setex s 20 1 OK 127.0.0.1:6379> ttl s (intege
