Android - Hide date field in datepickerdialog

Question

How to hide/remove date field in datepickerdialog. Actually my requirement is to use the native date picker dialog but it shows up with day, month, and year. But as per my requirement i need only month and year. So i want to hide or remove the day field from the view.

Any help will be much usefull.

Answer 1

I don't recommend using Reflection to do this kind of thing.

There is a simpler and more pretty way to do so:

((ViewGroup) datePickerDialog.getDatePicker()).findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE);

Be aware that .getDatePicker() method from DatePickerDialog works on API LEVEL >= 11.

Answer 2

The source code to DatePicker and DatePickerDialog are available for you to clone, refactor into your own package, and modify to suit.

Answer 3

((ViewGroup) datePickerDialog.getDatePicker()).findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE); 

This works properly

Answer 4

    private Calendar mCalendar;
    mCalendar = Calendar.getInstance();// Initialize Calendar

dialog_date_picker.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/rounded_corners"
android:orientation="vertical"
android:padding="8dp">
<DatePicker
    android:id="@+id/date_picker"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="4"
    android:calendarViewShown="false"
    android:datePickerMode="spinner" />
<Button
    android:id="@+id/date_time_set"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:background="@color/colorPrimary"
    android:text="Set"
    android:textColor="@color/colorWhite" /></LinearLayout>

DialogMethod called on Click:

private void ExpiryDialog() {
    System.out.println("Inside Dialog Box");
    final Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.dialog_date_picker);
    dialog.show();
    final DatePicker datePicker = (DatePicker) dialog.findViewById(R.id.date_picker);
    date_time_set = (Button) dialog.findViewById(R.id.date_time_set);
    datePicker.init(mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH), null);

    LinearLayout ll = (LinearLayout) datePicker.getChildAt(0);
    LinearLayout ll2 = (LinearLayout) ll.getChildAt(0);
    ll2.getChildAt(1).setVisibility(View.INVISIBLE);

    date_time_set.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View view){
            dialog.dismiss();
            Integer month = datePicker.getMonth()+1;
            Integer year = datePicker.getYear();
            expMonth = (month.toString().length()   == 1 ? "0"+month.toString():month.toString());
            expYear = year.toString();
            etExpiryDate.setText(expMonth + "/" + expYear);
        }
    });
}

This code works and hides the day in a DatePicker, so I can show Expiry Date for Cards. Enjoy!!

Answer 5

Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH);
int mDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), AlertDialog.THEME_HOLO_DARK,
new DatePickerDialog.OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        txtMonth.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);
    }

}, mYear, mMonth, mDay);
((ViewGroup) datePickerDialog.getDatePicker()).findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE);
datePickerDialog.show();

I am a little too late but posting the edited answer provided by @ULHAS PATIL above that works in case someone needs the same thing!

private Calendar mCalendar;
mCalendar = Calendar.getInstance();// Initialize Calendar

The xml layout:

<?xml version="1.0" encoding="utf-8"?>

There should be index 0 to hide the date filled, in ll2.getChildAt(0).setVisibility(View.GONE); and visibility set to View.GONE so the space for the date field is not occupied.

private void createDialogWithoutDateField() {
    Calendar mCalendar;
    mCalendar = Calendar.getInstance();
    System.out.println("Inside Dialog Box");
    final Dialog dialog = new Dialog(requireContext());
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.date_picker_layout);
    dialog.show();

    final DatePicker datePicker = (DatePicker) dialog.findViewById(R.id.date_picker);
    AppCompatButton okBtn = (AppCompatButton) dialog.findViewById(R.id.ok);
    AppCompatButton cancelBtn = (AppCompatButton) dialog.findViewById(R.id.cancel);
    datePicker.init(mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH), null);

    LinearLayout ll = (LinearLayout) datePicker.getChildAt(0);
    LinearLayout ll2 = (LinearLayout) ll.getChildAt(0);
    ll2.getChildAt(0).setVisibility(View.GONE);
    okBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
            Integer month = datePicker.getMonth() + 1;
            Integer year = datePicker.getYear();
            String expYear = year.toString();
            tvMonthYear.setText(month+ " " + expYear);
        }
    });
 cancelBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
        }
    });
}
