To really understand the usage of SQLite we will create an app . Here i have written the code to validate the input fields Email and Password using the Input Validation class which i described above. Also code for navigation to login screen on the click of login link and shows snackbar with success message for registration. In on Bind View Holder() method the appropriate User data (name,email and password) set to each row. The App contains simple Login form, Registration form and listing of registered user. List; public class Database Helper extends SQLite Open Helper Now create a layout file for the Login i.e activity_and add the below code in your layout file. Also code for navigation to registration screen on the click of registration link and to user list screen after click on login button if credentials are valid. package com.androidtutorialshub.loginregister.activities; import package com.androidtutorialshub.loginregister.adapters; import android.support.v7.widget.

The following demonstrates how to work with an SQLite database.If the user scrolls the list, then the rows and their associated views will be scrolled out of the visible area.The Java objects which represent the rows can be reused for newly visible rows.This app shows how SQLite database operations are performed. The code will create a simple login form containing logo on the top, 2 input fields email and password, login button and registration screen navigation link. Text Input Edit Text; import android.support.design.widget. package com.androidtutorialshub.loginregister.activities; import android.content. I assume that you have created a new android project. Create a new package named sql and create Database Helper class. SQLite Open Helper; import com.androidtutorialshub.loginregister.model. Create a package named helpers and create a class in it named Input and add below code in it.
