java - Manually input date in edittext -

i want manually (i.e. numeric keyboard) input date in dd-mm-yyyy format in edittext field. assign 3 integer variables, day, month, year calculation in such way first 2 characters (i.e. index 0, 1) day variable automatically add separator ("-' or "/") next 2 digit should month variable automated separator before , year. day , month should display 2 digit leading 0 (if necessary). if user enter 4-9 in day field @ index zero(0) automatically convert 2 digit , move month field, month 2-9 make 2 digit , move year. when input process completes move cursor next edittext field. apologize poor english. kind of appreciated. in advance.

you can use this. edge cases not handled. those.
