Add progress to any button by few lines of code without layout changes

Main features:

• No layout changes required
• Few lines of code to add
• Easy configurable
• Customizable
• Built in fade animations

Gradle dependency

allprojects {
  repositories {
    mavenCentral()
  }
}

implementation 'com.github.razir.progressbutton:progressbutton:2.1.0'

How to use

Basic example

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    // bind your button to activity lifecycle
    bindProgressButton(myButton)

    // (Optional) Enable fade In / Fade out animations 
    myButton.attachTextChangeAnimator()

    // Show progress with "Loading" text
    myButton.showProgress {
        buttonTextRes = R.string.loading
        progressColor = Color.WHITE
    }

    // Hide progress and show "Submit" text instead
    myButton.hideProgress(R.string.submit)
}

Showing AnimatedDrawable

val animatedDrawable = ContextCompat.getDrawable(this, R.drawable.animated_check)  
//Defined bounds are required for your drawable  
animatedDrawable.setBounds(0, 0, 40, 40)  

button.showDrawable(animatedDrawable) {  
  buttonTextRes = R.string.saved  
}

Avoiding memory leaks

To avoid memory leaks you always need to bind your button to a LifecycleOwner (usually Activity, or Fragment) :

[LifecycleOwner].bindProgressButton(button)
