How to navigate from one screen to another screen

How to navigate from one Activity screen to another Activity screen? In the first screen I'm having one button if I click the button it has to move to another Activity screen.

The most trivial case (called from activity):

startActivity(new Intent(this, ActivityToLaunch.class));

More details here: http://developer.android.com/guide/topics/fundamentals.html

OnClickListener onClickListener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        startActivity(new Intent(action));
    }
};

Button button = (Button) findViewById(id);
button.setOnClickListener(onClickListener);
