If you format the field to show a list, you can select either Yes or No, True or False, or On or Off from the list, again depending on the format applied to the field.You cannot enter values in the list or change the values in the list directly from a form or table. Microsoft Office Access 2007 provides a number of tools for updating existing records, including datasheets, forms, queries, find-and-replace, and the new Data Collection feature.As you proceed, remember that updating data is not the same process as entering new data.
In some cases, you can use conversion functions to perform calculations on the data in a Text field.
In Android development, any time you want to show a vertical list of items you will want to use a List View which is populated using an Adapter to a data source.
When we want the data for the list to be sourced directly from a SQLite database query, we can use a Cursor Adapter.
In turn, those design principles affect how you enter data.
Remember these facts about database objects and design as you proceed.
