android.widget.Switch - on/off event listener?

Question

I would like to implement a switch button, android.widget.Switch (available from API v.14).

<Switch
    android:id="@+id/switch1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Switch" />

But I'm not sure how to add an event listener for the button. Should it be an "onClick" listener? And how would I know if it is toggled "on" or not?

Answer 1

Switch inherits CompoundButton's attributes, so I would recommend the OnCheckedChangeListener

mySwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        // do something, the isChecked will be
        // true if the switch is in the On position
    }
});
