Creating an Android To-Do List Application from Scratch with Android Studio
Welcome to this new Android tutorial video in which we will be creating an Android to-do list application from scratch using Android Studio. Do note that this video will be slightly longer than usual as we will be covering everything from creating an app to customizing designs. The application that we will be creating will be a to-do list app, as it is a commonly used format. Within the app, we will have the ability to create different pages to-do lists, along with a functional search bar to search for the different tasks within the to-do list. In this tutorial, we will be covering the basics of Android Studio, creating databases, sending objects from one activity to another, creating customizable designs, and creating the search bar. Although I am not a professional Android developer, I have been using Android Studio for about a year and have tried my best to make the tutorial as clear and informative as possible. If you have any questions, feel free to ask in the comments, and I will try to answer them as soon as possible. Without further ado, let’s begin!
Creating the Main Page
The first thing we will be doing is creating the main page that will contain the to-do list. Although the tutorial will not be focused on creating a visually appealing design, we will cover the basics of how to create an Android app and other essential components. To start, we will be focusing on the XML file that will allow us to display things on the screen. We will be changing the RelativeLayout to a LinearLayout, which will align the list of to-do elements vertically. We will be using the orientation attribute to set it to vertical, which means that anything we add from this point on will be displayed vertically.
Next, we will create a TextView, which allows us to display text. We will customize the text by using the textColor attribute and setting it to a hexadecimal color code. The color code that I have used is fff556e. We will also use the gravity attribute to align the text in the center and increase its size to 25 sp. This TextView will be the title of the page that we are creating.
After creating the title, we will create a search bar that will allow us to search for the different pages of to-do lists and the to-do items within them. We will be using an EditText, which allows the user to input text. We will set it to match the parent’s width and then set a hint, which will disappear once the user starts typing. We will also change the color of the text and the background using the textColorHint and backgroundColor attributes, respectively. Additionally, we will set the inputType attribute to textMultiLine, which allows the user to add multiple lines of text.
Finally, we will create a list of elements using a RecyclerView. We will set it to match the parent’s width and height and set its unique identifier to list_view_todo. This will display the list of to-do items beneath the search bar. We will then create a button that will allow the user to add a new page of to-do items. This button will be created using a CircleButton library and will be styled in a circular shape with a specific background color.
This tutorial has covered the basic elements of creating an Android application using Android Studio. Although we have not covered every aspect of Android Studio, we have covered the essential components needed to create a to-do list app. We have created a main page that displays a title, a search bar, a list of to-do items, and a button to add a new page of to-do items. As you become more familiar with Android Studio, you can further customize your to-do list application by adding more features such as reminders or notifications. This tutorial serves as a foundation for anyone looking to create an Android app and contains the necessary components to get started.
