Android SQLite RecyclerView Tutorials and Examples.

Top Android SQLite RecyclerView Examples

Let's look at some examples.

Android RecyclerView SQLite CRUD tutorial.

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.

Yes,we continue with the Android SQlite database tutorials.Our mission on the web is to provide quality realworld,practical examples.There is alot of theory on books but not very practical examples.That's our aim at ProgrammingWizards. Today we see how to insert data to sqlite database from an input dialog,select that data and show it in a RecyclerView. We shall also see how to delete.Now for deleting we shall use a ContextMenu. User longclicks/long presses a RecyclerView card,then selects the action to perform. In short :

  •  INSERT,SELECT and DELETE data to and from SQlite database.
  •  When uses longpresses,he gets presented with a ContextMenu to select the action to perform.
  • If he selects "New" we show an input dialog.While if he selects "Delete",we delete the data from our database.

Our mission at ProgrammingWizards Youtube Channel  is to provide practical realworld examples.There is alot of theory on the web.But then its always easier to learn by doing.So we aim to fill that gap by providing quality examples,that you can easily extend and use in your app. Today we talk about Swipe To Delete,of course from Swipe to Dismiss.We use ItemTouchHelper class,no third party library.We shall do these:

  •  INSERT,SELECT and DELETE to and from SQLite database.
  • To delete we shall use the Swipe to dismiss technique,in this case swipe to delete from database.
  • We then refresh our adapter for instant change notifications.

Good morning/afternoon/evening guys.Today we continue with our SQlite Database series of tutorial.Episode 10.We talk about how to implement Swipe To Refresh in our RecyclerView with SQLite database.Of course we start from scratch,so we shall tackle inserting and selecting and ofcourse creating our table.

In short this is what we do in this episode 10:

  1. INSERT data to SQLite database.
  2. SELECT data from our SQLite database.
  3. Reload/Refresh data from our SQLite database when the user swipes/pulls down our RecyclerView.

We are covering how to search/filter data against our SQLite database.Take note we are filtering at the SQlite side,not in java but in SQL,at the server side if you like.Our widget today is RecyclerView.We of course start from scratch,inserting,then selecting while applying a search.  

Hello friends,today we basically discuss the following,in a practical was as we always do obviously:

  1. Download Images From the Web,in an image hosting site in my case, or anywhere for you.
  2. Save the image URLs and some text that we type in beautiful Material EditTexts. 3. Save these to our database : name and image url.Our SQLite database.
  3. Retrieve them from our database,our name and image url.
  4. Show them in our custom RecyclerView : images and text.
  5. We use the nice Picasso library to download and cache images automatically,both in memory and disk.

Hey guys.In this tutorial we continue looking at the SQlite Pagination. How to page/paginate data endlessly. We use the Load More technique. The user scrolls the RecyclerView,when he reaches the end of the list,we load more data from SQlite database.

We are performing our SQlite pagination at the server side. While loading our data using the endless scroll,we shall be displaying a ProgressBar as the data loads. Our RecyclerView comprises cardviews.

We first insert/save data into SQlite database via a dialog, then select the data and bind to our RecyclerView. We also see how to swipe/pull to refresh our data.

SQLite Database Overview

  • Database.SQLite package was added in API 1.
  • It contains classes enabling us communicate and manage SQLite databases.
  • Database.SQLite.SQLiteDatabase is a class we shall use frequently.
  • It derives from Android.Database.SQLite.SQLiteCloseable and Java.Lang.Object.
  • It has methods we shall use to perform CRUD operations.
  • Of course it can also execute SQL statements directly.
  • Always within a single application, a database name has to be unique.

This tutorial helps us explore Android SQLite database searching or filtering data.

First we have to save data and retrieve data from that database.

We render the data in our RecyclerView.

We will be searching/filtering data at the sqlite server level as opposed to fetching all data and filtering via Java.

Let's go.

We want to see how we can implement a ItemTouchHelper with a RecyclerView filled from SQLite database.

Thus if the user swipes away a RecyclerView item, that item is deleted automatically from the database.

But first we see how to insert into mysql database , then retrieve that data and show in a RecyclerView. Then user can delete by swiping away.

This is an android sqlite tutorial.

We first see how to perform CRUD adding data to sqlite database. Then we retrieve the data and bind to a RecyclerView.

Then when the user can show up an an input dialog and add more data. Those data don't get show immediately.

He can then swipe down/ or pull down the RecyclerView to refresh the data.

We use the SwipeRefreshLayout to enable this swiping functionality.

Best Regards, Oclemy.
