此外，下面所描述的本申请不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
下面将结合附图对本申请的实施例进行详细描述。
图1A示出了根据本申请实施例的缓存存储空间示意图，图中示意性地示出了n份缓存空间，用于分别顺序加载图像文件1、图像文件2、……图像文件n，n的大小可以根据移动终端所带缓存的大小而预先出厂设定，也可以由用户根据自己的使用习惯自行设定，例如可以设定为100。
本申请实施例提供的缓存管理方法如图2A所示，该方法可以适用于手 机、平板电脑等移动终端，该方法包括如下步骤：
S11.获取图像文件。
S12.判断预设缓存存储空间是否已存满。即判断图1A中所示的缓存存储空间是否已经存满，即是否已经存储了n个图像文件，当未存满时，和现有的缓存管理方法相同，将所获取的图像文件顺序加载到空的缓存存储空间；当缓存存储空间已存满时，则执行步骤S13。
S13.检测用户手指在屏幕上的滑动方向。当用户手指上滑时，移动终端屏幕上会显示出之前未显示过的图像文件，当用户手指下滑时，用户就可以在移动终端屏幕上回看之前显示过的图像文件。
S14.释放缓存存储空间的与用户手指滑动方向相同方向上最靠前的存储空间。具体地，当检测到用户手指上滑时，具体参见图1B和图2B，释放缓存存储空间最上方的存储空间，即释放图像文件1所占用的存储空间；当检测到用户手指下滑时，具体参见图1C和图2B，释放缓存存储空间最下方的存储空间，即释放图像文件n所占用的存储空间。
S15.将获取的图像文件加载到所释放出的存储空间并放入缓存存储空间的与用户手指滑动方向相反方向上最靠前位置。具体地，当检测到用户手指上滑时，具体参见图1B和图2B，将获取的图像文件加载到所释放出的存储空间并放入缓存存储空间最下方，即将获取的图像文件n+1加载到所释放出的存储空间，并放在存储图像文件n所占用的缓存存储空间下方；当检测到用户手指下滑时，具体参见图1C和图2B，将获取的图像文件加载到所释放出的存储空间并放入缓存存储空间最上方，即将获取的图像文件0加载到所释放出的存储空间，并放在存储图像文件1所占用的缓存存储空间上方。
当检测到用户手指继续上滑或下滑时，移动终端重复执行步骤S13至S15，顺序释放缓存存储空间的与用户手指滑动方向相同方向上最靠前的存储空间，将获取的图像文件加载到所释放出的存储空间并顺序放入缓存存储空间的与用户手指滑动方向相反方向上最靠前位置，从而一直保持缓存空间中只存储n个图像文件，不至于占用过多缓存，保持移动终端运行流 畅。
通过上述步骤，移动终端不断释放缓存存储空间的与用户手指滑动方向相同方向上最靠前的存储空间，并将获取的图像文件加载到所释放出的存储空间并放入缓存存储空间的与用户手指滑动方向相反方向上最靠前位置，从而不管用户手指如何上滑或下滑，移动终端始终只存储固定数量的图像文件，由此可以保持缓存不会占用过多，保持移动终端运行流畅。
作为一种优选实施方式，图像文件是位图(bmp)格式文件，这样移动终端在打开该文件时可以直接显示，而无需解码操作，打开更为迅速。优选地，当图像文件不是位图格式文件时，例如为jpg格式时，移动终端将其转换成位图格式，并将该位图格式文件加载到缓存中，由此即可以迅速打开该文件。
相应地，本申请实施例提供了一种缓存管理装置，该装置适用于手机、平板电脑等移动终端，如图3所示，该装置包括：
获取单元21，用于获取图像文件。
判断单元22，用于判断预设缓存存储空间是否已存满。即判断图1A中所示的缓存存储空间是否已经存满，即是否已经存储了n个图像文件，当未存满时，和现有的缓存管理方法相同，将所获取的图像文件顺序加载到空的缓存存储空间。
检测单元23，用于当判断单元22判断缓存存储空间已存满时，检测用户手指在屏幕上的滑动方向。当用户手指上滑时，移动终端屏幕上会显示出之前未显示过的图像文件，当用户手指下滑时，用户就可以在移动终端屏幕上回看之前显示过的图像文件。
释放单元24，用于释放缓存存储空间的与用户手指滑动方向相同方向上最靠前的存储空间。
加载单元25，用于将所获取的图像文件加载到所释放出的存储空间并放入所述缓存存储空间的与用户手指滑动方向相反方向上最靠前位置。
当用户手指继续上滑或下滑时，释放单元24和加载单元25重复顺序工作，顺序释放缓存存储空间的与用户手指滑动方向相同方向上最靠前的 存储空间，将获取的图像文件加载到所释放出的存储空间并顺序放入缓存存储空间的与用户手指滑动方向相反方向上最靠前位置，从而一直保持缓存空间中只存储n个图像文件，不至于占用过多缓存，保持移动终端运行流畅。
通过上述装置，移动终端不断释放缓存存储空间的与用户手指滑动方向相同方向上最靠前的存储空间，并将获取的图像文件加载到所释放出的存储空间并放入缓存存储空间的与用户手指滑动方向相反方向上最靠前位置，从而不管用户手指如何上滑或下滑，移动终端始终只存储固定数量的图像文件，由此可以保持缓存不会占用过多，保持移动终端运行流畅。
其中，释放单元24可以包括：
第一释放单元，用于当检测到用户手指上滑时，释放缓存存储空间最上方的存储空间，具体参见图1B，即释放图像文件1所占用的存储空间；
第二释放单元，用于当检测到用户手指下滑时，释放所述缓存存储空间最下方的存储空间，具体参见图1C，即释放图像文件n所占用的存储空间。
其中，加载单元25可以包括：
第一加载单元，用于当检测到用户手指上滑时，将所获取的图像文件加载到所释放出的存储空间并放入所述缓存存储空间最下方，具体参见图1B，即将获取的图像文件n+1加载到所释放出的存储空间，并放在存储图像文件n所占用的缓存存储空间下方；
第二释放单元，用于当检测到用户手指下滑时，将所获取的图像文件加载到所释放出的存储空间并放入所述缓存存储空间最上方，具体参见图1C，即将获取的图像文件0加载到所释放出的存储空间，并放在存储图像文件1所占用的缓存存储空间上方。
作为一种优选实施方式，图像文件是位图(bmp)格式文件，这样移动终端在打开该文件时可以直接显示，而无需解码操作，打开更为迅速。优选地，当图像文件不是位图格式文件时，例如为jpg格式时，移动终端将其转换成位图格式，并将该位图格式文件加载到缓存中，由此即可以迅速打 开该文件。
本申请实施例还提供了一种移动终端，其包括如上所述的缓存管理装置，从而移动终端可以不断释放缓存存储空间的与用户手指滑动方向相同方向上最靠前的存储空间，并将获取的图像文件加载到所释放出的存储空间并放入缓存存储空间的与用户手指滑动方向相反方向上最靠前位置，从而不管用户手指如何上滑或下滑，移动终端始终只存储固定数量的图像文件，由此可以保持缓存不会占用过多，保持移动终端运行流畅。
