Android MySQL - Best RecyclerView Examples.


Android MySQL RecyclerView Examples and Tutorials.

MySQL is our database while PHP is the server side language we use. The client code is for android is written in this case in either Java or Kotlin.

RecyclerView is our component.

But first:

What is a RecyclerView?

A RecyclerView is an adapterview that allows us display a large data set through just a limited window.

RecyclerViews were introduced in Android API 5 as an alternative to ListViews. ListView as you may already know is also an adapterview and allows us display items in a vertically scrolling list.

The term RecyclerView comes from a combination of two words: Recycler and View.

The term Recycler comes from the verb recycle which means to treat things that have already been used so that they can be used again if Oxford Advanced Learner's Dictionary* is to be believed.

Collins Cobuild English Dictionary tells us that a view refers to the way in which a piece of text or graphics is displayed on a computer screen.

And to be honest those two terms in a way defines us exactly what a RecyclerView is. In that a RecyclerView recycles views. It reuses views. And those views are just pieces of grahpical user interface widgets that normally we define in XML and get inflated in java.

RecyclerViews are not limited to any one particular view. Instead it can utilize any. Be it TextViews, Buttons, checkBoxes etc.

Let's look at some examples.

This is an Android MySQL Search tutorial.

The world we live in is indeed large.The data we have is in astonishing quantity.Even programming,atleast in most cases involve manipulating or reading some data.

This tutorial is no exception.Our aim is to see how to filter data from our MySQL database.Then we show our results in Realtime. We are performing a server-side search.Generally speaking,this is much faster than filtering at the client.Its faster than say,downloading your data to the device,then filling some sort of arraylist.Then filtering the arraylist.

What if am having 100,10000,1 million records etc.You get the point. You'll hog the users bandwidth.And it takes time.Writing optimized java code to search can be tricky itself.Now we can save ourselves some trouble.Perform the search on the big beefy servers.Then download results.

SQL is normally optimized for search/select performance.And we trust it better than ourselves. Anyway we use java.net.HttpURLConnection class,a subclass of java.net.URLConnection.

Android PHP MySQL RecyclerView AsyncTask tutorial. How to select and show in a RecyclerView.

Hi.Here's what we do :

  • Connect to Network via HttpURLConnection.
  • Download data in a background thread.
  • We are using PHP and MySQL database.PHP retrieves the data from MySQL.Then encodes it to json and we download.
  • We then parse this json data natively using jsonarray and jsonobject.
  • We fill an arraylist and bind to our RecyclerView.

Cheers.
