title: Date Picker appereace broke
body: <p>I'm using a fragment of code to open a DatePicker in Android programmatically:</p>
  
  <p>Using the same API 28 targeting and Emulator, In my main project, the date picker show with this appearance:</p>

  <p>While using the same code in another fresh project, it produce normal DatePicker:</p>
  
  <p><a href="https://imgur.com/a/8klLKKU" rel="nofollow noreferrer">Fresh Project</a></p>
  
  <p>The code is following:      </p>
  
  <pre><code>Calendar calendar = Calendar.getInstance();
  int year = calendar.get(Calendar.YEAR);
  int month = calendar.get(Calendar.MONTH);
  int day = calendar.get(Calendar.DAY_OF_MONTH);
  DatePickerDialog datePickerDialog = new DatePickerDialog(ScrollingActivity2.this, 
              new DatePickerDialog.OnDateSetListener() {
                  @Override
                  public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
  
                  }
              }, year, month, day);
  datePickerDialog.show();
  </code></pre>
  
  <p>I'm expecting to get the normal, default DatePicker, I'm feeling the problem is from theme or XML layout but cannot identified where is the error, any help is appreaciated.</p>
