TextView

A TextView object represents text on the screen.

Example:

<TextView android:id="@+id/swimmernameid"
   android:layout_height="fill_parent"
   android:layout_width="wrap_content"
   android:height="25dip"
   android:text="Swimmer Name"
/>

You can declare a reference variable to the TextView in code.
You only need a reference variable if you need to refer to the TextView.

private TextView swimmerNameView;

You can get a reference to it by calling findViewById.
You usually do this in the onCreate method.

swimmerNameView = (TextView) findViewById(R.id.swimmernameid);

You can call methods in code using the reference variable.
swimmerNameView.setText("Swimmer Name");
