For example if we want to get the user’s email we can check the entered email is a valid email or not before storing it inside the database. So lets start our Android Form Validation tutorial. Android provides a long list of “input types” that you can set in the layout XML to “set the user up for success” so that they can only enter permissible characters or numbers.For example: an input type of “phone” leads to only numbers, and characters such as -, (, ) being available for the user to enter: The XML to achieve this is shown below: The challenge is finding the proper list of input type values to use in the layout XML and what they make the Android device do. Next up: what you can do when the user changes the text in a field and still manages to enter something incorrect, even though we set them up for success above.Well, if it can be done unobtrusively, the next best time to validate is when the user is actually entering the text (this is also where we can implement the cool icon and error message shown in the first screen).

If it is, then the form is not valid: I created this method in the Contact Validator Factory class and then called it from the submit method tied to the submit button on the form. package net.simplifiedcoding.androidvalidationexample; import android.support.v7 On Click Listener So thats all for this Android Form Validation Tutorial friends. And also don’t hesitate to leave your comments if you are facing any troubles.I have heard lots of questions about how to develop for Android OS lately, so I’ve made a point to explore more about native Android programming.
