Question

Can you please explain the project in simpler terms and give me detailed step by step instructions to complete the project successfully. will thumbs up thank you

To create a basic user interface
• To create event listeners and handlers for UI components
• To create a basic test plan
• To work with fragments
• To handle orientation changes
Instructions
You are charged with creating a simple calculator. You must satisfy the following requirements:
Functional and interface requirements:
• Positive and negative numbers
• Real numbers
• +, -, *, /, and % (modulus -not percentages like a regular calculator)
• Square root
• Clear options
o C clears the entire display screen and the current calculation.
o CE clears the most recent entry (e.g., the last digit you just entered)
• The user must interact with the buttons, not the software keyboard
• The app must handle rotations and still be beautiful and usable

You must use: buttons, text views to complete the assignment
• You must provide a test plan with at least three days on separate worksheet tabs indicating
the tests that were performed
• You must use fragments (one for top display, and one for bottom with buttons)
o If you do not use fragments, you will lose a significant number of points

Answer 1

To create a calculator application, one must design the UI, implement event listeners, use fragments for layout, handle orientation changes, and prepare a test plan. Avoid using the software keyboard and make sure the app works beautifully in all orientations.

Step-by-step explanation:

Instructions for Creating a Simple Calculator Application

To fulfill the requirements of creating a simple calculator, follow these detailed steps:

1. Design the Interface: Start by designing a user-friendly interface with buttons for positive and negative numbers, real numbers, the basic arithmetic operations (+, -, *, /, and %), square root, and the clear options (C and CE).
2. Implement Event Listeners: Write event listeners and handlers for each button to perform their corresponding operations when clicked.
3. Create Fragments: Use fragments in your application; one for the display at the top and one for the keypad at the bottom.
4. Handle Orientation Changes: Ensure the app remains functional and aesthetically pleasing even after orientation changes.
5. Develop a Basic Test Plan: Create a test plan document with separate worksheet tabs for at least three different days detailing all the tests performed.

Remember that using the software keyboard should not be supported for inputs, only button interactions. Moreover, it is highly recommended to familiarize yourself with your calculator, experimenting with operations such as squaring, square roots, and conversions.
