方法详细资料

setMemCacheSizePercent

public void setMemCacheSizePercent(float percent)

Sets the memory cache size based on a percentage of the max available VM memory. Eg. setting percent to 0.2 would set the memory cache to one fifth of the available memory. Throws IllegalArgumentException if percent is below 0.01 or more than .8. memCacheSize is stored in kilobytes instead of bytes as this will eventually be passed to construct a LruCache which takes an int in its constructor. This value should be chosen carefully based on a number of factors Refer to the corresponding Android Training class for more discussion: http://developer.android.com/training/displaying-bitmaps/

参数:

percent - Percent of available app memory to use to size memory cache
