Create an Android application that allows users to input their names and store them in a local SQLite database. The application should include a user interface with an EditText where users can enter their names, a Button for saving the name to the database, a Button for displaying all saved names, and a TextView for showing the list of names stored in the database.

$$

For database handling, create an SQLite database named UserDatabase with a table called Users.

$$

The Uses table should have two columns: id$,$ which is an integer and serves as the primary key with auto$-$increment functionality, and name, which is a text field. Implement methods to insert a name into the database and to retrieve all saved names.

$$

Write the XML layout for the activity to include the mentioned user interface components. Additionally write the Java code for the activity to handle inserting names into the database and displaying them in the TextView when the user clicks the $$Show all Names$$ button. $(25$ Marks$)$
