![]() Let's define addContact() onClick function to insert a new cotact.when we click on this button a second screen will appear and then we can insert a new contact.Create a class called addNewContact also create an xml file called store_contact.xml to design the page. If you run this app you will see a contact list with search box.when you click on any item it will show contact ID.Now we will modify our app by adding some buttons for working with insert new contact, delete and update function that we already defined. Private static class DatabaseHelper extends SQLiteOpenHelper Designing xml Layout activity_main.xml file Public static String dbTable = "contacts" Public static String dbname = "ContactsDB" If you have some basic about sql command than it will be easy for you to understand Android SQLite database.However this tutorial is for everyone who wants to develop android app using SQLite.Īs exapmle, the name of our database is "ContactsDB", it has one table called "contacts" with five columns (_id, name, number, email, address) In this tutorial I’ll be discussing how to write classes to handle all SQLite operations. SQLite is a very light weight database which comes with Android OS. when you click on any list item, a new screen will come with details of selected contacts.A search filter helps you to find a specific contact.To edit, insert and delete an item this app will also contain some buttons.Īndroid provides several ways to store user and app data. In this tutorial we are going to make an app that shows you a list of some contacts. ![]() Import 7.app.Today i will discuss about android SQLite database with complete example ( create, insert, update, delete, filter) Now open your main activity file MainActivity.java from \java\ path and write the code like as shown below MainActivity.java ![]() Once we create a new layout resource file details.xml, open it and write the code like as shown below details.xml Now we will create another layout resource file details.xml in \res\layout path to show the details in custom listview from SQLite Database for that right click on your layout folder à Go to New à select Layout Resource File and give name as details.xml. Now open activity_main.xml file from \res\layout folder path and write the code like as shown below. If you observe above code, we implemented all SQLite Database related activities to perform CRUD operations in android application. When we want the data for the list to be sourced directly from a SQLite database query, we can use a CursorAdapter. Public class DbHandler extends SQLiteOpenHelper ) Once we create a new class file DbHandler.java, open it and write the code like as shown below DbHandler.java ![]() Once we create an application, create a class file DbHandler.java in \java\ path to implement SQLite database related activities for that right-click on your application folder à Go to New à select Java Class and give name as DbHandler.java. In case if you are not aware of creating an app in android studio check this article Android Hello World App. Android SQLite ListView Exampleįollowing is the example of creating the SQLite database, insert and show the details from the SQLite database into an android listview using the SQLiteOpenHelper class.Ĭreate a new android application using android studio and give names as SQLiteExample. Now we will see how to create & insert data into SQLite Database and how to retrieve and show the data in custom listview in android application with examples. To know more about using SQLite Database in android applications, check this Android SQLite Database Tutorial with Examples. In case, if we want to deal with large amounts of data, then the SQLite database is the preferable option to store and maintain the data in a structured format. Generally, in our android applications Shared Preferences, Internal Storage and External Storage options are useful to store and maintain a small amount of data. To know more about SQLite, check this SQLite Tutorial with Examples. SQLite is an open-source lightweight relational database management system (RDBMS) to perform database operations, such as storing, updating, retrieving data from the database.
