How to Hide showed Toast Messages in Android?

In my App, there is a list, when a user clicks on an button, a toast message is being displayed, 10 items - 10 toast messages, so if the user clicks 10 times, then presses the button... he/she has to wait for some seconds, until he's able to read the menu option text.

I have found the below solution to hide the shows toast message.

public class SampleToastActivity extends Activity {

Toast myToast;

static int i=0;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Button b1 = (Button) findViewById(R.id.button2);

b1.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

i++;

if(myToast!=null){

      myToast.cancel();

      myToast.setText("Count"+i);

      }else{

          myToast = Toast.makeText(SampleToastActivity.this, "Sample"+i, 10);

         }

      myToast.show();

   }

    });

  }

}
