Toggle Buttons

A toggle button allows the user to change a setting between two states.

You can add a basic toggle button to your layout with the ToggleButton object. Android 4.0 (API level 14) introduces another kind of toggle button called a switch that provides a slider control, which you can add with a Switch object. SwitchCompat is a version of the Switch widget which runs on devices back to API 7.

If you need to change a button's state yourself, you can use the CompoundButton.setChecked() or CompoundButton.toggle() method.

Toggle buttons

Switches (in Android 4.0+)

Key classes are the following:

• ToggleButton
• Switch
• SwitchCompat
• CompoundButton

Responding to Button Presses

To detect when the user activates the button or switch, create an CompoundButton.OnCheckedChangeListener object and assign it to the button by calling setOnCheckedChangeListener(). For example:

val toggle: ToggleButton = findViewById(R.id.togglebutton)
toggle.setOnCheckedChangeListener { _, isChecked ->
    if (isChecked) {
        // The toggle is enabled
    } else {
        // The toggle is disabled
    }
}

ToggleButton toggle = (ToggleButton) findViewById(R.id.togglebutton);
toggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if (isChecked) {
            // The toggle is enabled
        } else {
            // The toggle is disabled
        }
    }
});
