How to build a customized React Native activity indicator

Mobile apps utilize various graphical user interface (GUI) elements to facilitate user interactions, such as buttons for logging in. The response time of these interactions can be immediate or delayed, with delayed responses requiring visual cues to prevent users from perceiving the app as malfunctioning. React Native provides the ActivityIndicator component to display a circular loading animation for actions with extended response times, and this component can be customized in size, color, and positioning to align with an app's theme and style. This tutorial explains how to implement and customize the ActivityIndicator in React Native, offering practical examples and alternative methods using third-party libraries for more advanced customization. It demonstrates how to conditionally render the indicator, integrate it into overlays and modals, and modify animations with the Animated API. Furthermore, it introduces libraries like react-native-progress for creating custom indicators and highlights the importance of using appropriate loading animations to improve user experience in mobile applications.
