You are to create a mobile application using Java and Android Studio according to the following

specifications. Note that you are to only use commands and techniques covered in the textbook and the

tutorials.

The application will consist of three screens or pages.

$1.$ A page using a RecyclerView that displays a list of all properties for sale.

$2.$ A page using a ViewPager that displays details for each individual property.

$3.$ A page to add new property.

Clicking on a list item will open the details page for that property $($in the ViewPager$)$ and provide facilities

to edit the details. Note that the new$/$updated data will be held in a Temporal Data Structure.

Properties List Page

The properties list page will implement a scrollable RecyclerView listing all properties. The RecyclerView

must use a view holder, data adapter and custom layout.

Each list item will be displayed in the format shown above and include:

$1.$ The Street Address, suburb, state, postcode

$2.$ The Sale Price

Text must be constructed as shown and the font must be set appropriately for the first line.

An initial set of properties $($as shown above$)$ must be displayed on startup.

Clicking on a list item will open the corresponding details page containing the information for the

selected property. These details can be changed, and by clicking the back button, the property's

information will be updated, and the user will navigate back to the main page $($i$.$e$.,$ the properties list

page$).$

Buttons

If the New Property button is selected:

$$ The New Property page is opened. $($The fields on the details page will be cleared$)$

$$ Clicking the Back button will discard the new property and return to the property's list page.

If the Save button is selected:

$$ The application will return to the property's list page.

$$ The property's list page will display the updated list with the new property.

Errors

A toast must be shown with an error message if the Save button is selected and either of the following

occurs:

$1.$ The address or suburb field is empty

$2.$ The price is not a whole number and is less than $1000$

If an error has occurred, the application will stay on the new property details page.
