Answer 1

The most trivial case (called from activity):

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

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

Answer 2

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

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

Answer 3

Button x.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) 
             {
              Intent i = new Intent(y.this, Activity.class);
              startActivity(i);           
             }
        });

Here we've defined a listener for Button x. The OS will call this method and start the Activity referenced in Intent i.
