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

Question

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

Answer 1

Use the following snippet to add a Switch to your layout via XML:

Then in your Activity's onCreate method, get a reference to your Switch and set its OnCheckedChangeListener:

Switch onOffSwitch = (Switch)  findViewById(R.id.on_off_switch); 
onOffSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    Log.v("Switch State=", ""+isChecked);
}       

});
