What is an Auction / Bidding App?

This application is an auction organizing application. This application will help the users to organize an online auction of their products. Other users on this app will make their bid and the owner of the product can see the bids that people made on his product. He can choose the winner of the auction.

The Flow of the Application

We have designed a home screen with 3 buttons.

My Products Screen

In my products screen, the user can add a product for auction. He can see all the products that he has put on auction. There is also an ‘i’ button in which he can see all the bids made by users on his products. There is a ‘make winner’ button and he can choose to make the bidder as winner of the auction.

Auction List

In the auction list, the user can see all the products that are listed for auction. He can click on any product and place a bid on it and the bid will be submitted successfully.

Winner List

In the Winner list, the user can see the winner of all the auctions that occur on the app.

Features of Auction app

The features of Bidding Android App :

  1. The user will register on the app and can organize an auction or participate in one.
  2. Users can add new products for auction.
  3. Users can see the bids made by people on his product.
  4. Users can choose the winner of the auction.
  5. Users can participate in auctions of other users and can place bids on their products.
  6. Users can see the list of winners of all the auctions.

Project Prerequisites

You should have a fair idea of how the auction apps work. The project requires you to have good knowledge of the following technologies/tools.

  1. Java: Android apps are developed in Java.
  2. XML: The application interface is designed in XML.
  3. Android Virtual Device: We will test our application on an Android virtual device.
  4. Android Libraries: It is necessary to be familiar with Android libraries like CircularImageView
  5. Firebase: You should be familiar with NoSQL databases like firebase.
  6. Theme: Knowing how to use a theme in an app is also important.

Developing the Android Auction App

Ok, so before getting to implement the android auction app, we’ll understand the files that we have created for this application. Let us see them one by one-

  1. We have created activity_main.xml to manage the interface of our main screen.
  2. MainActivity.java is the next file. This is where the Main screen is handled.
  3. SignIn.xml is the screen to handle the interface of our signing in the app. And SignIn.java will handle the logic part of it.
  4. SignUp.xml is the screen for handling the interface of a user registering in the app, while SignUp.java handles the logic.
  5. In the next step, we need to create xml files for handling the UI of our module. To handle their code, we need to create the corresponding java files.
  6. Lastly, we have developed some other files that were required for the application’s interface, which are listed below:
    1. colors.xml: There are descriptions of the colors in this file, so the color name can be easily referenced.
