This android library is like a tour guide for your app's Views. It helps to explain to your user, the role of the Views in your Activity or Fragment. It supports minSdk 21 and up.

Step 1. Add the jitpack repository to the repositories { } function, inside your project build.gradle or your settings.gradle like so:

repositories {
    google()
    mavenCentral()
    // Place the jitpack repository inside this, like so:
    maven { url 'https://jitpack.io' }
}

Step 2. Add the dependency in your module build.gradle file, like so:

dependencies {
    implementation "com.github.germainkevinbusiness:UIPresenter:2.0.0"
}

That's it!

Basic usage is shown below, with more examples in the sample app.

UIPresenter(activity = this).set(
    viewToPresent = binding.recyclerView[2], // using view binding here
    descriptionText = "This is a row inside the RecyclerView with an animal image and name",
    presenterStateChangeListener = { _, _ -> }
)

Only the above three parameters inside the UIPresenter.set() method are required to display a Presenter on your Activity or Fragment's UI. The rest of the parameters in the UIPresenter.set() method are optional, but great for customization!

For more in-depth examples, check out the sample app.

To create your own animation when the presenter is being added to the decorView (called revealAnimation), or when the presenter is being removed from the decorView (called removeAnimation) , you need to implement the PresenterAnimation interface, like so:

class MyCustomAnimation : PresenterAnimation {

    override fun runAnimation(
        coroutineScope: CoroutineScope, // A scope to run your animation in, if you want
        presenter: Presenter, // The Presenter is the View which presents your UI and the View that
        // your custom animation will animate.
        animationDuration: Long, // The duration of the animation in milliseconds
        afterAnim: () -> Unit // When called that means we can safely consider this animation to be done
    ) {
        // write your animation logic here
    }
}

You can apply your own animations to the UIPresenter like so:

UIPresenter(activity = this).set(
    revealAnimation = MyCustomAnimation(), // if it's a reveal animation
    removeAnimation = MyCustomAnimation() // if it's a remove animation
)
