Android How do I correctly get the value from a Switch?

Question

I'm creating a Android application which uses a Switch.
I'm trying to listen for changes and get the value when changed.
I have two questions when using switches:

1. What action listener do I use?
2. How do I get the the switch value?

Answer 1

Switch s = (Switch) findViewById(R.id.SwitchID);  if (s != null) {     s.setOnCheckedChangeListener(this); }  /* ... */  public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {     Toast.makeText(this, "The Switch is " + (isChecked ? "on" : "off"),                    Toast.LENGTH_SHORT).show();     if(isChecked) {         //do stuff when Switch is ON     } else {         //do stuff when Switch if OFF     } } 

Hint: isChecked is the new switch value [true or false] not the old one.
