The stepper-indicator project is a lightweight and customizable Android library that provides a step-by-step progress indicator. It can be used to display the progress of a multi-step process, such as a signup flow or a tutorial.

Pros

• Lightweight and Customizable: The library is lightweight and provides a wide range of customization options, allowing developers to easily integrate it into their Android applications.
• Smooth Animation: The library offers smooth animations when transitioning between steps, providing a polished user experience.
• Flexible Step Configuration: Developers can easily configure the number of steps, the text and icon for each step, and the overall appearance of the indicator.
• Accessibility Support: The library includes support for accessibility features, making it easier to integrate into applications that cater to users with disabilities.

Cons

• Limited Functionality: The library is focused solely on providing a step-by-step progress indicator, and does not include additional features or functionality beyond this core purpose.
• Dependency on Android SDK: The library is designed specifically for Android and requires the use of the Android SDK, which may limit its cross-platform compatibility.
• Potential Performance Issues: Depending on the complexity of the application and the number of steps being displayed, the library may have performance implications, especially on older or lower-end devices.
• Lack of Extensive Documentation: While the project includes some documentation, it may not be as comprehensive as some developers would prefer, which could make it more challenging to integrate into complex projects.

Code Examples

Here are a few examples of how to use the stepper-indicator library in your Android application:

1. Initializing the Stepper Indicator:

val stepperIndicator = StepperIndicator(context)
stepperIndicator.setStepCount(5) // Set the number of steps

2. Configuring the Stepper Indicator:

stepperIndicator.setCurrentStep(2) // Set the current step
stepperIndicator.setCompletedCircleColor(Color.GREEN) // Set the color of completed steps
stepperIndicator.setUncompletedCircleColor(Color.GRAY) // Set the color of uncompleted steps
stepperIndicator.setStepNumberTextSize(16f) // Set the text size of the step numbers

3. Handling Step Changes:

stepperIndicator.addStepChangeListener { currentStep ->
    // Handle the change in the current step
    // (e.g., update the UI, load the next screen)
}

4. Integrating the Stepper Indicator into a Layout:

<com.badoualy.stepperindicator.StepperIndicator
    android:id="@+id/stepper_indicator"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="16dp" />

Getting Started

To get started with the stepper-indicator library, follow these steps:

1. Add the library to your project's build.gradle file:

dependencies {
    implementation 'com.badoualy:stepper-indicator:1.0.7'
}

2. Create a StepperIndicator instance in your Android activity or fragment:

val stepperIndicator = StepperIndicator(this)
stepperIndicator.setStepCount(5) // Set the number of steps

3. Customize the appearance and behavior of the stepper indicator as needed:

stepperIndicator.setCurrentStep(2) // Set the current step
stepperIndicator.setCompletedCircleColor(Color.GREEN) // Set the color of completed steps
stepperIndicator.setUncompletedCircleColor(Color.GRAY) // Set the color of uncompleted steps
stepperIndicator.setStepNumberTextSize(16f) // Set the text size of the step numbers

4. Add the StepperIndicator to your layout:

<com.badoualy.stepperindicator.StepperIndicator
    android:id="@+id/stepper_indicator
