Top Android SQLite GridView Examples

Let's look at some examples.

An android sqlite database tutorial here.We see how save data to sqlite database from edittext,retrieve that data and show it in a simple gridview.

Nowadays most apps need or require to store content or data in some form.There is the cloud but it isn’t a replacement for local storage.Neither will it be in the near future.Storing data locally is important because its easily retrievable,doesn’t require internet connection and is fast.

Good old SQLite is still the way to go.Together with Realm database,they are two ways that are now common in data storage.The package we shall be using is android.database.sqlite

It Was added in API 1 and contains classes which your app can use when talking to and managing your database. Android does ship with SQLite database. As of now SQLite 3.4.0.

One of those classes is Android.database.sqlite.SQliteDatabase This class derives from android.database.SQLite.SQLiteCloseable and obviously,java.lang.Object. This class has methods that we can use to basically, manage our SQLite database. It has methods for CRUD stuff.

Hey good people. Society is now in an error of big data. There is alot of data out there and normally there are tools to manipulate it and store it.But when it comes to display, there is only one way of making it easy to process by users : showing it in chunks,otherwise known as pagination.

Thats exactly the purpose of this lesson,only that we use SQLite database and our platform is android.For SQlite we shall use RushORM, which is an amazing android SQlite database Object relational Mapper. The purpose is this :

  • INSERT/SAVE SQLite data into SQLite database from edittexts.
  • RETRIEVE/SELECT paged data.We do pur pagination in the server side hence it being relatively fast as SQlite queries are heavily optimized.
  • Show data page by page,each page containing five items.
  • You can continue adding more data and our GridView automatically gets updated.
  • We use Next/Previous pagination.If you are in the first page,we disable obviously previous button, if you are in the last page,we disable next button.
  • We are using RushORM.
  • Our GridView is custom and has CardViews as viewitems.
  • Here we see how to categorize SQLite data in swipeable tabs.
  • Each fragment shall have a unique dataset bound on a GridView.
  • The tabs and fragments are clickable and swipeable respectively.
  • We shall display a dialog to insert data.
  • The data shall be categorized according to categories.
  • The categories as well as data shall be fetched from the database.
  • The component of choice is GridView.
