clear USSD response Messages from screen

I am calling on USSD number using this

String ussdCode = "*" + "123" + Uri.encode("#");

startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussdCode)));

But it shows the response message on screen . How can I clear these messages from the screen??

Thanks in advance

This is not my solution. It is taken from here. If you know Russian you can read the whole article there. However here is their solition:

import com.example.android.UssdMessage.USSD;



public class UssdmessageActivity extends Activity implements OnClickListener {
        /** Called when the activity is first created. */
        private TextView view;
        private AutoCompleteTextView number;

        @Override
        public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);
                Button button = (Button) findViewById(R.id.button1);
                button.setOnClickListener(this);
                this.view = (TextView) findViewById(R.id.Text2);
                this.number = (AutoCompleteTextView) findViewById(R.id.Text1);
        }

        @Override
        public void onClick(View arg0) {
                String encodedHash = Uri.encode("#");
                call("*" + number.getText() + encodedHash);
                this.view.setText("");
        }

        protected void call(String phoneNumber) {
                try {
                        startActivityForResult(
                                        new Intent("android.intent.action.CALL", Uri.parse("tel:"
                                                        + phoneNumber)), 1);
                } catch (Exception eExcept) {
                        this.view.append("\n\n " + "\n" + eExcept.toString());
                }
        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
                USSD ussd = new USSD(4000,4000); // передается два параметра, задержка до и после (ms) создания сообщения
                if (ussd.IsFound())
                        this.view.append("\n"+ussd.getMsg());
                else
                        this.view.append(""+R.string.error_ussd_msg);
        }
}

They rely on this class for ussd parsing.

After implementing this activity you can clear the TextView with the ussd message. Or you can finish an activity.
