        .observeOn(AndroidSchedulers.mainThread())  
        .subscribe( { parameters ->  } ) 

Coroutines

KeyboardHeight.observeKeyboardHeight(this)  
       .collect(object : FlowCollector<Parameters> {  
           override suspend fun emit(value: Parameters) {  
               // on keyboard changed   
           }  
       })

KeyboardHeight(this /* activity */ , object : KeyboardListener {  
    override fun onKeyboardChanged(parameters: Parameters) {  
        // on keyboard changed  
  }  
})

Parameters

Parameters is collection of keyboard-around parameters

data class Parameters(val keyboardHeightPixels : Int, val screenOrientation : Int) {  
  
    @get:JvmName("isPortrait")  
    val isPortrait  
        get() = screenOrientation == Configuration.ORIENTATION_PORTRAIT  
  
    @get:JvmName("isKeyboardOnScreen")  
    val isKeyboardOnScreen  
        get() = keyboardHeightPixels > 0  
}
