Android Question Add button and update button and delete buttons

Not quite sure I understand the question. I see you are a very new member of the forum welcome.

If I am correct then this is quite a bit of work - I am on my second endeavour with this type of app. I assume that you have read the document by @klaus (linked below) in which you will find an example of using the SQLite showing the listings in a database - that "panel" has add, delete and update built into it. You would need to work through the base user interface to call up the database, after, obviously, its been created and so on.

SQLite Databse Guide Booklet is here.

You can download this stuff and there are sample/example code files included. Of course, there are many other ways to design user interfaces for these operations but @klaus provides a recommended set of examples and explanations of all things SQLite.

trust this is of assistance.
