        DatePickerDialog.OnDateSetListener dialogpick = new DatePickerDialog.OnDateSetListener() {

            @Override
            public void onDateSet(DatePicker view, int year, int monthofyear,
                    int dayofmonth) {
                // TODO Auto-generated method stub
                cal.set(Calendar.YEAR, year);
                cal.set(Calendar.MONTH, monthofyear);
                cal.set(Calendar.DAY_OF_MONTH, dayofmonth);
                updateText();

            }

            private void updateText() {
                // TODO Auto-generated method stub

            }

        };
        TimePickerDialog.OnTimeSetListener timepick = new TimePickerDialog.OnTimeSetListener() {

            @Override
            public void onTimeSet(TimePicker view, int hourofday, int minute) {
                // TODO Auto-generated method stub
                cal.set(Calendar.HOUR_OF_DAY, hourofday);
                cal.set(Calendar.MINUTE, minute);
                updateText();

            }

            private void updateText() {
                // TODO Auto-generated method stub

            }

        };

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        if (v.getId() == R.id.button1) {

            new DatePickerDialog(MainActivity.this, dialogpick,
                    cal.get(Calendar.YEAR), cal.get(Calendar.MONTH),
                    cal.get(Calendar.MONDAY)).show();
        } else if (v.getId() == R.id.button2) {
            new TimePickerDialog(MainActivity.this, timepick,
                    cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE))
                    .show();
        }

    }

TimePickerDialog.OnTimeSetListener timepick = new TimePickerDialog.OnTimeSetListener()

timepick is a local variable in onCreate(). You cannot access local variables in another method such as onClick().

You can move the declaration and instantiation of timepick to class member level, that is outside of onCreate(). You can access member fields from all instance methods.

The same goes for dialogpick.
