public class Button
extends TextView

Button represents a push-button widget. Push-buttons can be pressed, or clicked, by the user to perform an action. A typical use of a push-button in an activity would be the following:

 public class MyActivity extends Activity {
     protected void onCreate(Bundle icicle) {
         super.onCreate(icicle);

         setContentView(R.layout.content_layout_id);

         final Button button = (Button) findViewById(R.id.button_id);
         button.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Perform action on click
             }
         });
     }
 }
