android - How to change a TextView's text by pressing a Button

Question

I want to change the of a TextView by pressing a Button, but don't understand how to do it properly.

This is part of my layout:

<TextView android:id="@+id/counter"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Text" />
<Button android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Change text!" />

And this is my activity:

public class Click extends Activity {
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
        final Button button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // Perform action on click
                // ???
            }
        });
    }
}

What should I put inside onClick() method?

According to: http://developer.android.com/reference/android/widget/TextView.html

TextView view = (TextView) findViewById(R.id.counter);
view.setText("Do whatever");
