To do this we need to override the newView method and the bindView method. Next, we need to define the adapter to describe the process of projecting the Cursor's data into a View. We can simply create an XML layout template in res/layout/item_todo.xml, representing a particular cursor row: When we want to display a series of items into a list, using a custom representation of the items, we need to use our own custom XML layout template for each item. To create this database table, we would use SQLite persistence or an ORM that allows us to define objects mapped to tables. In this case, we will define a database table called todo_items for a collection of todo items with a string body and an integer priority. For every single item in the ListView this layout creates the following view for every single item in the array adapter. Under layout, the folder creates a layout as customlistview.xml and invokes the following code. Using a Custom CursorAdapter Defining our Tableįirst, we need to define a table within the database from which we will load our cursor. Step 3: Creating a custom View for ListView. Which fields of the cursor to bind to which views in the template.Which layout template to inflate for an item.The CursorAdapter fits in between a Cursor (data source from SQLite query) and the ListView (visual representation) and configures two aspects: When we want the data for the list to be sourced directly from a SQLite database query, we can use a CursorAdapter. In Android development, any time you want to show a vertical list of items you will want to use a ListView which is populated using an Adapter to a data source.
