Cannot Resolve the 'DatePickerFragment' - android

When I tried to implement the date picker in android it showed me the following error.
Cannot Resolve the 'DatePickerFragment'.
Can anyone help me to solve this? I am referring to this link and this screenshot
datepick.xml

DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getSupportFragmentManager(), "datePicker");
}
}

You have no DatePickerFragment in your package and you have no import for it.

add the below class in your package:
class DatePickerFragment extends DialogFragment
implements DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
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);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
// Do something with the date chosen by the user
TextView tv1= (TextView) getActivity().findViewById(R.id.textview1);
tv1.setText("Year: "+view.getYear()+" Month: "+view.getMonth()+" Day: "+view.getDayOfMonth());
}
}

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"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.inducesmile.mydatepicker.MainActivity">
<EditText
android:id="#+id/display_dob"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="24dp"/>
<Button
android:id="#+id/select_dob"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="16dp"
android:textColor="#000000"
android:textSize="15sp"
android:text="Select your Date of birth"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"/>
</RelativeLayout>
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

Setting date using DialogFragment and Android Annotations

I have problem with writing date I selected in DatePicker with Dialog Fragment.
I`m trying to do this using Android Annotations. Problem is, I have to implement behavior for setting this date to TextView on OnDateSet function in DatePickerFragment class.
How can I choose in which TextView, which #Click should write?
Code below:
#EActivity(R.layout.activity_main_search)public class SearchActivity extends FragmentActivity{
private int mFYear, mFMonth, mFDay, mTYear, mTMonth, mTDay;
(R.id.main_search_city)
EditText cityET;
#ViewById(R.id.main_search_price)
EditText priceET;
#ViewById(R.id.main_search_from)
TextView dateFromTV;
#ViewById(R.id.main_search_to)
TextView dateToTV;
public static class DatePickerFragment extends DialogFragment
implements DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
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);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
}
}
#AfterViews
public void setCurrentdateonView(){
final Calendar c = Calendar.getInstance();
mFYear = c.get(Calendar.YEAR);
mFMonth = c.get(Calendar.MONTH)+1;
mFDay = c.get(Calendar.DAY_OF_MONTH);
dateFromTV.setText(new StringBuffer().append(mFDay).append("-").append(mFMonth).append("-").append(mFYear).append(""));
dateToTV.setText(new StringBuffer().append(mFDay).append("-").append(mFMonth).append("-").append(mFYear).append(""));
}
#App
HApplication mApp;
#Click(R.id.main_search_from_btn)
public void showFromDatePickerDialog(View v) {
DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getSupportFragmentManager(), "datePicker");
}
#Click(R.id.main_search_to_btn)
public void showToDatePickerDialog(View v) {
DialogFragment newFragment = new DatePickerFragment();
newFragment.show(getSupportFragmentManager(), "datePicker");
}
#Click(R.id.main_search_btn)
public void openSearch(){
//SearchActivity_.intent(this).city(cityET.getText().toString()).start();
ListActivity_.intent(this).city(cityET.getText().toString()).price(priceET.getText().toString()).start();
}}
Functions that should realise that date writing are:
#Click(R.id.main_search_from_btn)
public void showFromDatePickerDialog(View v)
it should write date to dateFromTV
and
#Click(R.id.main_search_to_btn)
public void showToDatePickerDialog(View v)
it should write date to dateToTV
I SOLVED THE PROBLEM.
What I needed was flags, which were set on each button #Click and then in onDateSet case switch with flag number check. Maybe it will help someone, because it took me whole day to figure it out...
The Click annotation is just for triggering the dialog.
You should implement a callback method through listener interfaces described here:
http://developer.android.com/guide/topics/ui/dialogs.html#PassingEvents
EDIT: I implemented a version for myself, here is the code:
MainActivity.java:

TextView lbl_from, lbl_to, cpn_from, cpn_to;
#Override

super.onCreate(savedInstanceState);

cpn_from = (TextView) findViewById(R.id.cpn_from);
cpn_to = (TextView) findViewById(R.id.cpn_to);
lbl_from = (TextView) findViewById(R.id.lbl_from);
lbl_to = (TextView) findViewById(R.id.lbl_to);
}
public void showFromDatePickerDialog(View v) {
DialogFragment newFragment = new DatePickerFragment();
Bundle bundle = new Bundle();
bundle.putBoolean("isFromDate", true);
newFragment.setArguments(bundle);
newFragment.show(getSupportFragmentManager(), "datePicker");
}
public void showToDatePickerDialog(View v) {
DialogFragment newFragment = new DatePickerFragment();
Bundle bundle = new Bundle();
bundle.putBoolean("isFromDate", false);
newFragment.setArguments(bundle);
newFragment.show(getSupportFragmentManager(), "datePicker");
}
#Override
public void onDatePicked(DialogFragment dialog, Calendar c,
boolean isFromDate) {
String strdate = null;
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
if (c != null) {
strdate = sdf.format(c.getTime());
}
if (isFromDate) {
lbl_from.setText(strdate);
} else {
lbl_to.setText(strdate);

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.support.v4.app.DialogFragment;
import android.widget.EditText;
public class DatePicker extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstaceState){
return inflater.inflate(R.layout.fragment_charting, container, false);
}
EditText mEdit;
#Override
public void onStart() {
super.onStart();
}
public void selectDate(View view) {
DialogFragment newFragment = new SelectDateFragment();
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

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:
- android.widget.DatePicker (Open Class, Show Error Log)
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.
