Android DatePickerDialog Api 23 (Android 6)

Question

I am triggering a DatePickerDialog, It's working and showing fine till api 22 (Android 5.1), I am setting mix and max dates on it (min = current date, max = 1 month starting from current date), but It's just showing current date in Api 23, I attached code and images.

///////////////////////////////datepickerdialog///////////////////////////////
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState){
        final Calendar calendar = Calendar.getInstance();
        int year = calendar.get(Calendar.YEAR);
        int month = calendar.get(Calendar.MONTH);
        int day = calendar.get(Calendar.DAY_OF_MONTH);

        /*
            Create a DatePickerDialog using Theme.

                DatePickerDialog(Context context, int theme, DatePickerDialog.OnDateSetListener listener,
                    int year, int monthOfYear, int dayOfMonth)
         */

        // DatePickerDialog THEME_DEVICE_DEFAULT_LIGHT
        DatePickerDialog dpd = new DatePickerDialog(getActivity(),this,year,month,day);

        if (Build.VERSION.SDK_INT < 22){

            dpd.getDatePicker().setCalendarViewShown(true);
            dpd.getDatePicker().setSpinnersShown(false);
            dpd.getDatePicker().getCalendarView().setShowWeekNumber(false);

        }

        calendar.setTimeInMillis(calendar.getTimeInMillis());
        long mindate = calendar.getTime().getTime();
        calendar.add(Calendar.MONTH, 1);
        long maxdate = calendar.getTime().getTime();

        dpd.getDatePicker().setMinDate(mindate);
        dpd.getDatePicker().setMaxDate(maxdate);

        dpd.getDatePicker().setMinDate(mindate);

        if(Build.VERSION.SDK_INT < 23){

            dpd.setTitle("");

        }

        // Return the DatePickerDialog
        return  dpd;
    }

    @SuppressLint("SimpleDateFormat")
    public void onDateSet(DatePicker view, int year, int month, int day){
        // Do something with the chosen date

        month++;

        evento_fecha = year+"-"+month+"-"+day;          


        month--;

        datetime.set(Calendar.YEAR, year);
        datetime.set(Calendar.MONTH, month);
        datetime.set(Calendar.DAY_OF_MONTH, day);

        SimpleDateFormat mSDF = new SimpleDateFormat("dd/MM/yyyy");
        fecha = mSDF.format(datetime.getTime());

        //fecha_seleccionada.setText(dia+"/"+mes+"/"+year);
        fecha_seleccionada.setText(fecha);

    }
} 

ANSWER 1: Results

Answer 1

DatePicker / DatePickerDialog not appearing properly on Android Marshmallow / API 23 is a theme issue. I suggest, instead of using default theme or writing custom styles, instantiate the DatePickerDialog using 'theme' option:

DatePickerDialog(Context context, int theme, DatePickerDialog.OnDateSetListener listener, int year, int monthOfYear, int dayOfMonth)

API 23 onwards, Material theme should be used for the dialog. Use android.R.style.Theme_Material_Light_Dialog_Alert for the theme parameter.

For Xamarin Android - use Android.Resource.Style.ThemeMaterialLightDialogAlert.

Answer 2

I was using this style in my theme:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="colorPrimary">@color/green_sheet</item>
    <item name="android:textColorPrimary">@color/textColorPrimary</item>
    <item name="android:textAllCaps">false</item>     

</style> 

The textColorPrimary property was showing all days numbers in white, I used this property in order to set the action bar text to white. I was wrong because I had to use Theme.AppCompat.Light.DarkActionBar for this purpose, so I changed my theme style to this:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="colorPrimary">@color/green_sheet</item>

    <item name="android:textAllCaps">false</item>     

</style>

and the result was as expected.

In your DatePicker you have set MinDate to currentTimeMillis() and in your MaxDate you have add 1 MONTH to your Calendar.

Just simple use this code.

public class MainActivity extends Activity {

    int mYear, mMonth, mDay;

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


        final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);

        final TextView textView = (TextView)findViewById(R.id.textview_totalStone);
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                DatePickerDialog dpd = new DatePickerDialog(MainActivity.this,
                        new DatePickerDialog.OnDateSetListener() {
                            @Override
                            public void onDateSet(DatePicker view, int year, int month, int day) {
                                c.set(year, month, day);
                                String date = new SimpleDateFormat("MM/dd/yyyy").format(c.getTime());
                                textView.setText(date);

                                mYear = c.get(Calendar.YEAR);
                                mMonth = c.get(Calendar.MONTH);
                                mDay = c.get(Calendar.DAY_OF_MONTH);
                            }
                        }, mYear, mMonth, mDay);
                dpd.getDatePicker().setMinDate(System.currentTimeMillis());

                Calendar d = Calendar.getInstance();
                d.add(Calendar.MONTH,1);

                dpd.getDatePicker().setMaxDate(d.getTimeInMillis());
                dpd.show();


            }

        });

    }

In my DatePicker I have Date June 25 and it select and as your requirement you have MaxDate 1 Month it's show in ScreenShot.

ScreenShot : 1

ScreenShot : 2

Update :

Replace your this code

calendar.setTimeInMillis(calendar.getTimeInMillis());
        long mindate = calendar.getTime().getTime();

        dpd.getDatePicker().setMinDate(mindate);

with this

  dpd.getDatePicker().setMinDate(System.currentTimeMillis());
