I cant be able to set datepicker starts from tomorrows date(Material Design Datepicker)

Iam using Material Design Datepicker i can be able to set from tomorrows date but todays date is also showing in calendar i set for 29/11/2016 but it also showing 28/11/2016
How to disable that so that user cant select it
Iam using Material Design DatePicker
https://github.com/wdullaer/MaterialDateTimePicker
GregorianCalendar g1=new GregorianCalendar();
g1.add(Calendar.DATE, 1);
GregorianCalendar gc = new GregorianCalendar();
gc.add(Calendar.DAY_OF_MONTH, 30);
dateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
DatePickerDialog datePickerDialog ;
datePickerDialog = DatePickerDialog.newInstance(LoginSuccess.this, g1.get(Calendar.YEAR),
g1.get(Calendar.MONTH),
g1.get(Calendar.DAY_OF_MONTH));
datePickerDialog.setTitle("Select Date");
//datePickerDialog.setMinDate(g);
GregorianCalendar c2=new GregorianCalendar();
c2.setTimeInMillis(g1.getTimeInMillis()+(27*7*24*60*60*1000));
//c2.add(Calendar.DAY_OF_MONTH, 30);
List<Calendar> dayslist= new LinkedList<Calendar>();
Calendar[] daysArray;
Calendar cAux = Calendar.getInstance();
while ( cAux.getTimeInMillis() <= gc.getTimeInMillis())
{
if (cAux.get(Calendar.DAY_OF_WEEK)!=1)
{
Calendar c = Calendar.getInstance();
c.setTimeInMillis(cAux.getTimeInMillis());
dayslist.add(c);
}
cAux.setTimeInMillis(cAux.getTimeInMillis()+(24*60*60*1000));
}
daysArray = new Calendar[dayslist.size()];
for (int i = 0; i<daysArray.length;i++)
{
daysArray[i]=dayslist.get(i);
}
//g1.setTimeInMillis(g.getTimeInMillis()+(7*24*60*60*1000));
datePickerDialog.setMinDate(g1);
datePickerDialog.setMaxDate(c2);
datePickerDialog.show(getFragmentManager(), "DatePickerDialog");
datePickerDialog.setSelectableDays(daysArray);
}

Try this out!
dateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Calendar now = Calendar.getInstance();
now.add(Calendar.DAY_OF_YEAR, 1);
DatePickerDialog dpd = DatePickerDialog.newInstance(
MainActivity.this,
now.get(Calendar.YEAR),
now.get(Calendar.MONTH),
now.get(Calendar.DAY_OF_MONTH)
);
dpd.setMinDate(now);
dpd.setThemeDark(modeDarkDate.isChecked());
dpd.vibrate(vibrateDate.isChecked());
dpd.dismissOnPause(dismissDate.isChecked());
dpd.showYearPickerFirst(showYearFirst.isChecked());
if (modeCustomAccentDate.isChecked()) {
dpd.setAccentColor(Color.parseColor("#9C27B0"));
}
if(titleDate.isChecked()) {
dpd.setTitle("DatePicker Title");
}
dpd.show(getFragmentManager(), "Datepickerdialog");
}
});
}

g1.add(Calendar.DATE, +1);
check it like this

You should do this,
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, day + 1);
cal.set(Calendar.MONTH, month);
cal.set(Calendar.YEAR, year);
datePickerDialog.getDatePicker().setMaxDate(maxDate.getTimeInMillis());
this will restrict you to select current date and let you select the
date starts from tomorrow.

From what I recall from the documentation for this library, I believe that if you set the selectable days for MaterialDateTimePicker then it overrides anything you have done set for min and max date. So if you pass an array of dates it will need to include your min and max dates, plus everything you want to see in between.

how to keep min Age Limit in Android

Am building an demo app, in which I would like to allow people who are above 21yrs, how do I do this.
I want to take there DOB and calculate the age, with the current year. I want to use DatePicker, but messed up seeing different snippets. thanks

This is a simple code that will guide your to achieve what your are planning for.
It uses a button click to launch the DatePicker Dialog
Layout file
<?xml version="1.0" encoding="utf-8"?>

Then the Activity class
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.Toast;
import java.util.Calendar;
public class MainActivity extends AppCompatActivity {
private DatePickerFragment datePickerFragment;
private static Calendar dateTime = Calendar.getInstance();
protected static int mYear;
protected static int mMonth;
protected static int mDay;
private static final int allowedDOB = 21;
protected static EditText displayDOB;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
displayDOB = (EditText)findViewById(R.id.display_dob);
Button dobButton = (Button) findViewById(R.id.select_dob);
dobButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
datePickerFragment = new DatePickerFragment();
datePickerFragment.show(getSupportFragmentManager(), "Select Your Birthday");
}
});
}
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Using current date as start Date
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
// Get DatePicker Dialog
return new DatePickerDialog(getActivity(), this, mYear, mMonth, mDay);
}
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
dateTime.set(mYear, monthOfYear, dayOfMonth);
long selectDateInMilliSeconds = dateTime.getTimeInMillis();
Calendar currentDate = Calendar.getInstance();
long currentDateInMilliSeconds = currentDate.getTimeInMillis();
SimpleDateFormat simpleDate = new SimpleDateFormat("dd/MM/yyyy", Locale.getDefault());
String strDt = simpleDate.format(dateTime.getTime());
displayDOB.setText(strDt);
if (selectDateInMilliSeconds > currentDateInMilliSeconds) {
Toast.makeText(getActivity(), "Your birthday date must come before taday's date", Toast.LENGTH_LONG).show();
return;
}
long diffDate = currentDateInMilliSeconds - selectDateInMilliSeconds;
Calendar yourAge = Calendar.getInstance();
yourAge.setTimeInMillis(diffDate);
long returnedYear = yourAge.get(Calendar.YEAR) - 1970;
if (returnedYear < allowedDOB) {
Toast.makeText(getActivity(), "Sorry!!! You are not allowed to use this app", Toast.LENGTH_LONG).show();
return;
} else {
// move to another activity page
}
}
}
}

if you want to limit the age from datepicker itself you can do like this,
<com.deevita.patient.Custom_Layouts.editText
android:id="#+id/dob"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:drawableStart="#drawable/ic_date_icon"
android:drawablePadding="#dimen/drawable_padding"
android:focusable="false"
android:hint="#string/birthday"
android:inputType="date"
android:padding="#dimen/padding_common_new"
android:textSize="#dimen/font_small">
</com.deevita.patient.Custom_Layouts.editText>
add the following code in java
dob.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.YEAR,-21); // the age you want to limit
int yy = calendar.get(Calendar.YEAR);
int mm = calendar.get(Calendar.MONTH);
int dd = calendar.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
String date = String.valueOf(dayOfMonth) + "-" + String.valueOf(monthOfYear + 1)
+ "-" + String.valueOf(year);
dob.setText(date);
}
}, yy, mm, dd);
datePicker.getDatePicker().setMaxDate(calendar.getTimeInMillis());
datePicker.show();
}
});

if user entered age
driverage = edtdriverage.getText().toString();
else if ( Integer.parseInt(driverage)> 55 || Integer.parseInt(driverage)< 18) {
GlobalMethods.Toast(AddDriverActivity.this, getString(R.string.enter_driver_age_min));
cancel = true;
}
you can achieve by validation method also

Android DatePicker Button not working

Ok so i have this app i'm working on... It has a left menu slide-out using ABS and the sliding menu lib. Here's my fragment that is launched once the menu item is selected. This fragment is suppose to have a text field to display the date you select and a button to select a date. Any idea's on what i'm doing wrong that SelectDateFragment is erroring?
Here's the XML layout:
<EditText
android:id="#+id/dateselected"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="20dp"
android:layout_marginTop="56dp"
android:ems="10"
android:inputType="date" >
<requestFocus />
</EditText>
<Button
android:id="#+id/pickdate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/dateselected"
android:layout_toRightOf="#+id/dateselected"
android:contentDescription="#string/selectdate"
android:cropToPadding="true"
android:onClick="selectDate"
android:src="#drawable/ic_datepicker" />
</RelativeLayout>
Here's the java class:
import java.util.Calendar;
import android.annotation.SuppressLint;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.support.v4.app.Fragment;

import android.widget.EditText;
public class DatePicker extends Fragment {
#Override

return inflater.inflate(R.layout.fragment_charting, container, false);
}
EditText mEdit;
#Override

super.onStart();
}
public void selectDate(View view) {

newFragment.show(getFragmentManager(), "DatePicker");
}
public void populateSetDate(int year, int month, int day) {
mEdit = (EditText)getView().findViewById(R.id.dateselected);
mEdit.setText(month+"/"+day+"/"+year);
}
public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar calendar = Calendar.getInstance();
int yy = calendar.get(Calendar.YEAR);
int mm = calendar.get(Calendar.MONTH);
int dd = calendar.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), this, yy, mm, dd);
}
#Override
public void onDateSet(android.widget.DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// TODO Auto-generated method stub
populateSetDate(year, monthOfYear, dayOfMonth);
}
}
}
EDIT:
I'm trying to follow http://javapapers.com/android/android-datepicker/
The error i'm getting is the fragment inner class should be static. I don't understand enough about this topic, and from reading more i still do not, to understand why his works and mine does not.

try this one
shipdate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(999);
}
});
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case 999:
// set date picker as current date
return new DatePickerDialog(this, datePickerListener, year, month,
day);
}
return null;
}
private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
final Calendar cf = Calendar.getInstance();
year = cf.get(Calendar.YEAR);
month = cf.get(Calendar.MONTH);
day = cf.get(Calendar.DAY_OF_MONTH);
// set selected date into textview
shipdate.setText(new StringBuilder().append(month + 1)
.append("-").append(day).append("-").append(year)
.append(" "));
}
};

DatePicker does not work

I am trying to use DatePicker in my Android app. When I add it to my layout, I get this message:
The following classes could not be instantiated:

See the Error Log (Window > Show View) for more details.
So I looked in the error log, and this is what I saw:

Android Date Picker month as number

In Android DatePicker, in some OS it shows Month as "Jan, Feb, Mar...Dec", on other it shows as 1,2,3..12
Is there a way to make it consistent througthout so that it should display 1,2,3.. 12 always as month?
Reason for displaying 1,2,3..12 instead of string is the localization support for various kind of languages.
Also is it advisable to do so?
Thanks.
