HW $2.$ Build an Interface using Android Studio

In this assignment, you will use Android Studio to build an App's interface $($without functions$).$ The objective is to get

familiar with views, layouts, and attribute settings.

The App contains a calculator and a calendar. Since it is not a functioning App, the default text on the upper region of

the whole screen will be $"$HW$2$ by FirstName LastName". Here you should use your name in this string.

An example App interface is shown below. You will submit three screenshots:

the App interface on an emulator$/$real device $($left$),$

the App on the background of the Android system $($middle$),$ and

the design view in Android Studio $($right$).$

To be specific,

The App interface should contain three parts: the text view, the calculator buttons, and the calendar $(30$ pts$)$

The whole screen should have top, bottom, left, and right margins set to $20$ dp $(5$ pts $)$

The text of the TextView should align to the center $(5$ pts$)$

The calculator buttons $($including digits and text on them$)$ should be placed exactly according to the shown

layout $(25$ pts$)$

The calendar shows your submission date $(5$ pts$)$

The screenshots of running the App $($i$.$e$.$ the left and the middle$)(30$ pts$).$
