You can get the time using

int hour = timePicker.getCurrentHour();
int minute = timePicker.getCurrentMinute();

Then you must create a thread to check out the current time and the time from TimePicker.

At the time, you have to close the app using System.exit(0); ou finish() your activity

REEDITED:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_contadorpro);

    timePicker = (TimePicker) findViewById(R.id.timePicker);
    button = (Button)findViewById(R.id.button);

    final Thread _thread = new Thread() {

        @Override
        public void run() {

            try {

                boolean _stopThread = true;

                while (_stopThread) {

                    Calendar _calendar = Calendar.getInstance();

                    int _currentHour = _calendar.get(Calendar.HOUR);
                    int _currentMinute = _calendar.get(Calendar.MINUTE);

                    int hour = timePicker.getCurrentHour();
                    int minute = timePicker.getCurrentMinute();

                    if (_currentHour == hour && _currentMinute == minute) {

                        _stopThread = false;

                        System.exit(0);

                    }

                }

            } catch (Exception e) {

                e.printStackTrace();

            }

        }

    };

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            // I edited here
            if(!_thread.isAlive()) {

                _thread.start();

                Toast.makeText(getApplicationContext(), "Contador Activado", Toast.LENGTH_LONG).show();

            }

        }
    });

}

Thank you very much Lennon, it finally works ;) A colleague has told me a code to that the thread is not running all the time, when I get it and test it i will edit — David P, Mar 12 '15 at 22:48
