Populating a Android ListView with MySQL data

I want to retrieve data from a MySQL database and populate a ListView in my Android application. I've seen answers on stackoverflow that use complicated methods of retrieving the data from a MySQL database using JSON objects. Instead, is there anyway I can use something similar to a MySqliteCursor to connect to a MySQL database? Is the Cursor Android class limited to using SQLite databases? If none of these options are possible, is there an easier way to populate a ListView with MySQL data?

See CursorAdapter class. It receive cursor, db column indicies and ids of widgets of view. Then it take data from db and populate corresponding fields

Yes, it receive Cursor from sqlite. You can easily implement adapter for any data- just know number of rows and query row under particular index. See RecyclerView tutorial (updated listview)

Update ListView based on SQLite backed ContentProvider

I'm a new Android Developer and seem to have gotten in a little over my head. I am trying to make a listView update when I add more content to the list.
The ListView is based off of a SQLite database. I was able to get the ListView to be based on the SQLite database by making a ContentProvider for the SQLite database (which was suggested here). Now my issue is that I want to update the SQLite database and have it reflected on the ListView. I am using a loader and according to this if I implemented the loader right it will monitor the data.
I tried updating the SQLite database directly but, that didn't cause the ListView to update without closing and reopening. My instinct from there is that I should implement the insert method in my contentProvider. I did a very simple implementation:
#Override
public Uri insert(Uri uri, ContentValues contentValues) {
return ContentUris.withAppendedId(uri, mCollectionDB.insertCollection(contentValues));
}
Unfortunately, the result of this is my app crashes with a "java.lang.NullPointerException". This is especially confusing as using the exact same contentValues to make the .insertCollection call from my MainActivity works without issue.
The issue I'm really interested in is how to get my listView to update when I insert data into my SQLite database. If inserting into the ContentProvider is irrelevant then please ignore that. I'm not really sure where I went wrong so I'm not sure what other code may be useful, but I'm happy to edit in more code if it'll help.

You can check loader concept.

The idea is simple insert data into database and on click of view button initialize List view with arraylist that contains data already inserted.

Display the entire table data in android listview

I kept my sqlite database in assets folder. I need to get the entire table data and should display it in listview. i.e each row of the table should be each item of the listview. How can I do this? Please help me in this regard. I worked on getting data from remote database server via php and json. Can we use the same json for getting data from local database. If so how can I do that?
Any suggestion will be thankful....

How many columns that you have in that table, if you more number of columns then you might need to think to show about 2 or 3 columns instead of all in the list view.
The below tutorial help you to retrieve the records from the table, please go through

android ListView subitem database

I'm making an application with a database of courses (of school) that the user is participating in. I want to display those courses in a list (im using listview) and use also the subitem (extra information of that course) of the listitems. I found a tutorial (http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/) that displays a list like I want but it uses a class to store the data in instead of a database. So the tutorial uses an arraylist of objects of that class. It would be a detour though if i had to put my information from my database into a class to put it in the list.
Does anyone have a clue how to solve this?
Thanks!

I found a beter way. By using a simple adapter and putting the values of the cursor in a hashmap in a arraylist. Found the idea from this site: http://eureka.ykyuen.info/2010/01/03/android-simple-listview-using-simpleadapter/

Here is a perfect tutorial for what you need. It shows you how to create a simple SQLite database and then populate a listview using the database.

Sqlite database is an open source database which provide relation data.It don't need any server or hosting it localy placed in android devices. To create and upgrade the android sqlite database you will need to extends SqliteOpenHelper class from child class. In this way you can create and upgrade your database.
