Get switch state in mainActivity Kotlin

  • 772

I have inside my mainActivty, a menu to which I set a Switch in this way

activity_main_drawer.xml

<item
                    android:icon="@drawable/ic_light"
                    app:actionLayout="@layout/menu_switch"
                    android:title="Modo"
                    />

And inside the menu_switch.xml

<Switch xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/nav_switch"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:clickable="true"
    android:focusable="true"
    />

How could I access the state of the switch (nav_switch) from the activityMain?, to grant actions in case the switch was checked or not. Thank you

kotlin

    To get the status of a Switch use OnCheckedChangeListener , define this listener to your Switch and you will be able to get its status:

     mySwitch.setOnCheckedChangeListener(object : CompoundButton.OnCheckedChangeListener{
                override fun onCheckedChanged(switch: CompoundButton?, isChecked: Boolean) {

                  if(isChecked) {
                     //Encendido
                  } else {
                    //Apagado
                  }


                }
            })
