if (arg0.getId() == R.id.btn1){

StringBuffer oStr1 = new StringBuffer();

oStr1.append("\nToggle 1 : " + oToggleB1.getText().toString());

oStr1.append("\nToggle 2 : "+ oToggleB2.getText().toString());

Toast.makeText(this, "State : " + oStr1.toString(), Toast.LENGTH_LONG).show();

Strings.xml

<?xml version="1.0" encoding="utf-8"?>

    <string name="action_settings">Settings</string>

<string name="btn1">Check Status</string>

</resources>

When we add toggle button in the code, it will give ON of OFF state by default which you can see in the first toggle button. But in most of the cases, we need to display different text for ON or OFF state, which we can achieve through textOn and textOff attributes of ToggleButton which are highlighted in above code. getText() method will return the current state of ToggleButton.
