I am trying to change visibility of two buttons when pressing one of them.

So say I have an "on" and an "off" button. When I press the on button, I want the on button to hide itself and the off button to show, and vice versa.

How could one do this?

See this example in Kotlin, adapt it for your own needs:

    val onButton = Button(this)
    val offButton = Button(this)
    onButton.setOnClickListener {
        onButton.visibility = INVISIBLE
        offButton.visibility = VISIBLE
    }
    offButton.setOnClickListener {
        onButton.visibility = VISIBLE
        offButton.visibility = INVISIBLE
    }

Or in Java:

    Button onButton = (Button) findViewById(R.id.onButton);
    Button offButton = (Button) findViewById(R.id.offButton);

    onButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            onButton.visibility = INVISIBLE;
            offButton.visibility = VISIBLE;
        }
    });

    offButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            onButton.visibility = VISIBLE;
            offButton.visibility = INVISIBLE;
        }
    });

Basically, you have to inform on to point.

1. How can I handle the visibility ?
2. How can I listen to a click event ?

You can handle the visibility of a view by using the
