name it ExpandableGridView looks make more sense,

Done.

I guess you no need this and the below constructor for now, especially this
constructor is usually used to construct in code without giving AttributeSet,

Done.

View.MEASURED_SIZE_MASK looks make more sense here, or 'Integer.MAX_VALUE &
View.MEASURED_SIZE_MASK' for easy to read,

[Hwanseung Lee, 2017/05/31 14:34:36]

Done.
