Example in Kotlin language (Java is also easy):

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val toggle = findViewById<LoadingToggleButton>(R.id.btn_toggle)

        // LoadingToggleButton interaction event
        toggle.setOnCheckChangeListener {loadingToggleButton, checked ->
            Log.d("DEMO", "toggle button is checked = " + checked)
        }

        toggle.setOnLoadingChangeListener { loadingToggleButton, isLoading ->
            Log.d("DEMO", "toggle button loading animation is showing = " + isLoading)
        }
        
        // show loading indicator animation
        btn_start_loading.setOnClickListener { toggle.start() }
        
        // hide loading indicator animation
        btn_start_loading.setOnClickListener { toggle.stop() }
    }
}
