You are calling setContentView(linearLayoutCalTvContainer); again after initially setting the layout R.layout.activity_user_dob as content view. This will override the previously set layout and everything contained in that layout will disappear. Why don't you create your complete layout solely in xml? Try something like this:

Put your DatePicker and TextView into your layout wherever you want them to be:

<DatePicker
        android:id="@+id/datePicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

<TextView 
        android:id="@+id/textViewUserDate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

And after setting your layout with setContentView(R.layout.activity_user_dob); you can retrieve the instances of your DatePicker and TextView like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_user_dob);

    // Get the instances of your DatePicker and TextView from the layout
    DatePicker datePickerBirthday = findViewById(R.id.datePicker);
    TextView textViewUserDate = findViewById(R.id.textViewUserDate);

    // Continue with the rest of the setup
    int currentapiVersion = android.os.Build.VERSION.SDK_INT;
    if (currentapiVersion >= 11) {
        datePickerBirthday.setCalendarViewShown(false);
    }
    ...
}

But be sure to never again call setContentView(...); after you initially set the layout to be R.layout.activity_user_dob.

I have used Datepicker Dialog Fragment, to show the Date picker in dialog.

Here is my Complete Code

MainActivity.java

package com.example.testmydrag;

import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.DatePicker;
import android.support.v4.app.FragmentActivity;
import android.app.Dialog;

import android.support.v4.app.DialogFragment;

import java.util.Calendar;

public class MainActivity extends FragmentActivity {

EditText mEdit;
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    public void selectDate(View view) {

        DialogFragment newFragment = new SelectDateFragment();
        newFragment.show(getSupportFragmentManager(), "DatePicker");

    }

    public void setTheDate(int year, int month, int day) {

        mEdit = (EditText)findViewById(R.id.Text);
        mEdit.setText(month+"/"+day+"/"+year);
    }
    /*
     * Date Picker Dialog
     */
    public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {

            final Calendar c = Calendar.getInstance();
            int yy = c.get(Calendar.YEAR);
            int mm = c.get(Calendar.MONTH);
            int dd = c.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog dialog = new DatePickerDialog(getActivity(),this,c.YEAR, c.MONTH, c.DATE);

            /*Calendar View if you want to Remove Set it to False*/
            dialog.getDatePicker().setCalendarViewShown(true);

            /*Spinner View if you want to Show Set it to True*/
            dialog.getDatePicker().setSpinnersShown(false);

            dialog.setTitle("Pick a date");
            return dialog;
        }
        public void onDateSet(DatePicker view, int yy, int mm, int dd) {

            setTheDate(yy, mm+1, dd);
        }
    }

I found a temporary solution, though I am not entirely happy with it. You need minimum SDK version 11 for this.

Basically I added a call to getDatePicker() in my onAcreateDialog function, mentioned in the DueDatePickerFragment, and then changed its settings. I don't understand why I need to do this, and why it is appearing so incorrectly in my emulator. No one else seems to be having this problem. Any explanations would be highly appreciated. Here is the code:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState){
    Log.i("DUEDATEPICKERDIALOG", "Inside onCreateDIALOG");
    final Calendar c = Calendar.getInstance();
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);
    DatePickerDialog datePickerDialogObj = new DatePickerDialog(getActivity(), this, year, month, day);

    DatePicker dueDatePicker = datePickerDialogObj.getDatePicker();
    float scaleVal = (float) 0.6;
    dueDatePicker.setScaleX(scaleVal);
    dueDatePicker.setScaleY(scaleVal);
    dueDatePicker.setCalendarViewShown(false);

    return datePickerDialogObj;
}

Hope this helps someone.

Simply way - just to hide NumberPicker in datePickerDialog here is code from my project

public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        final Calendar c = Calendar.getInstance();

        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, c.get(Calendar.YEAR),
                c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));

        dialog.getDatePicker().setSpinnersShown(true);

        // hiding calendarview and daySpinner in datePicker
            dialog.getDatePicker().setCalendarViewShown(false);

            LinearLayout pickerParentLayout = (LinearLayout) dialog.getDatePicker().getChildAt(0);

            LinearLayout pickerSpinnersHolder = (LinearLayout) pickerParentLayout.getChildAt(0);

            pickerSpinnersHolder.getChildAt(0).setVisibility(View.GONE);


        dialog.setTitle("Pick a date");
        return dialog;
    }

    public void onDateSet(DatePicker view, int yy, int mm, int dd) {

        Calendar result = Calendar.getInstance();

        result.set(Calendar.YEAR, yy);
        result.set(Calendar.MONDAY, mm);
        result.set(Calendar.DAY_OF_MONTH, dd);

        if (currentWeek != -1) {
            updateDateWeek(result.getTimeInMillis());
        } else {
            updateDate(result.getTimeInMillis());
        }
    }
}

to show picker just call

DialogFragment newFragment = new SelectDateFragment();
newFragment.show(getActivity().getSupportFragmentManager(), "DatePicker");
