State Delegator
State delegator is a collection of classes that helps you to manage a screen state and reduces boilerplate code.
Example
When changing a screen state you always have to show or hide the certain views:
when (state) {
LOADING -> {
loading_view.visibility = View.VISIBLE
content_view.visibility = View.GONE
stub_view.visibility = View.GONE
}
CONTENT -> {
loading_view.visibility = View.GONE
content_view.visibility = View.VISIBLE
stub_view.visibility = View.GONE
}
STUB -> {
loading_view.visibility = View.GONE
content_view.visibility = View.GONE
stub_view.visibility = View.VISIBLE
}
}To reduce a boilerplate code we use LoadingStateDelegate class:
val screenState = LoadingStateDelegate(content_view, loading_view, stub_view)
...
when (state) {
LOADING -> screenState.showLoading()
CONTENT -> screenState.showContent()
STUB -> screenState.showStub()
}Overview
Download
To get started using state-delegator is to add it as a gradle dependency.
You need to make sure you have the MavenCentral repository included in the build.gradle file in the root of your project:
repositories {
mavenCentral()
}Next add a dependency in the build.gradle file of your app module. The
following will add a dependency to the library:
dependencies {
...
implementation "com.redmadrobot:state-delegator:1.7"
}And that's all! :-)
