Hi, i am using textFielter in my CustomEditField in my login Page of my application. TextFilter.Interger is working well but the problem is that, it slows down the typing speed in my editField.. I am also posting my codes for my customTextFilter,LoginPage and CustomEdit Field.. Kindly give me solution and suggestions for that..
