Android Validators fields -

i have made many layout in android. kindly tell me best , easy way validate input field before save data database. required field. data should in number etc.

for input must number use @ edittext

for required field can use :

 private boolean isempty(edittext edittext) {         boolean isempty = false;         if (textutils.isempty(edittext.gettext())) {             isempty = true;             edittext.seterror("empty field");         }          return isempty     }
