All you have to do is add a listener. Like this:

button.setOnClickListener(mCorkyListener);

You can implement the listener in the same file or in a new file. Here is the complete example:

You don't need to create a new .java file. You can do it in the same mainactivity.
I assume that your have a layout file for your activity say, mainlayout.xml where you have put your button.

public class  mainactivity extends Activity{
         protected void onCreate(Bundle savedValues) {
                 setContentView(R.layout.mainlayout);

                 Button button = (Button)findViewById(R.id.myButton);
                 button.setOnClickListener(new View.OnClickListener() {
                    @Override
                     public void onClick(View v) {
                        //Handle your click event here.
                      }
              });
       }
}

Hope it helps.
