TUTORIAL 11
The Restaurant Store
In this tutorial, we will create a database and table for holding our
restaurant data and switch from our ArrayAdapter to a CursorAdapter, to
make use of that database. This will allow our restaurants to persist from
run to run of LunchList.
Step-By-Step Instructions..........................................................................
First, you need to have completed the previous tutorial. If you are
beginning the tutorials here, or if you wish to not use your existing work,
you can download a ZIP file with all of the tutorial results, and you can copy
the 10-Resources edition of LunchList to use as a starting point.
Step #1: Create a Stub SQLiteOpenHelper.........................................
First, we need to be able to define what our database name is, what the
schema is for the table for our restaurants, etc. That is best wrapped up in a
SQLiteOpenHelper implementation.
So, create LunchList/src/apt/tutorial/RestaurantHelper.java, and enter in
the following code:
package apt.tutorial;import android.content.Context;
import android.database.SQLException;
