In this guide, we’ll explore how to use Jetpack Compose to create an HourGlass animation. With the help of a declarative syntax, Jetpack Compose is a contemporary UI toolkit for creating native Android interfaces. Several Compose elements will be combined in our HourGlass animation to simulate the familiar Hourglass timing effect.
The Animation
Utilizing the Canvas
One of the most fascinating aspects of creating the HourGlass animation is the use of the Canvas Composable. Jetpack Compose provides the Canvas Composable, which allows us to draw custom graphics and shapes directly onto the screen. In our HourGlass animation, we take full advantage of the capabilities offered by Canvas to bring our hourglass to life.
Setting Up the HourGlass Animation
To begin, let’s create a Composable function called HourGlass that takes in a HourGlassViewModel and a HourGlassConfig. The HourGlassViewModel will provide us with the necessary data for our animation, while the HourGlassConfig will define the size and other configuration parameters of our hourglass.
