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

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)
I have some lists which containes data from the SQLServer. I want to display it in a single table in my android, which need 5 columns, how can i acheive this. what would be the besr method for doing this??
BTW i am a newbie in android
User Android ListView. https://developer.android.com/guide/topics/ui/layout/listview.html
Example here :
http://techlovejump.com/android-multicolumn-listview/
I put my data in 3 tables(Links, Images and PDF)
each table has columns(university, faculty, grade, and description,...)
I want to retrieve description column in the 3 tables.
where university, faculty, and grade equal to certain values.
and sort them with creation date.
how can I perform that query in parse?
I'm not familiar with Android, but I'm pretty sure Parse does not support "Join" in the way a SQL database does. You could nest the queries, performing the next one in the previous one's completion block.
However, if you regularly want to get data from those 3 tables, I'd suggest you make it 1 table instead, with a column "Content" instead of Link/Img/PDF. Images and PDFs would probably be stored as PFFiles anyway, and you can put link as either its own string column or putting it in a file. You could also add a column "type" if you want to be able to query a specific type, or just keep track of which columns contains which data.
Then you could query the "Content" class, on the keys you want.
I think this link might help you
https://parse.com/docs/js/guide#relations and it is quite simple and nicely explained . You can't do it directly in the database, though.
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.

I'm struggling to achieve what seems to me should be a simple goal.
I have a long list of vaule I want imported in to a database in one column with many rows.
I have no problems getting the data in in one row and many colums, but I can't figure out how to do it the other way round.
Is that possible??? if not is it possible to alter the table once the data in imported to swap to a manyx1 from a 1xmany table.
Thanks in advance.
As with any other database, if you want 10 rows of data, you have to perform 10 insert operations. So you would just loop over your list of values and for each one insert a new row into the database.
