I have custom datepicker and time picker.it was working fine befor api level 21 but after it is not working. i debugged the code and came to know that ondatechanged and ontimechanged is not called when i change the date.
So how to resolv ethis issue.
custom class of DatePicker is -
public class DatePickerDialog extends Dialog implements OnDateChangedListener,OnClickListener{
private static DatePickerDialog dialog;
private String date;
private String title;
private DatePickerCallback callback;
private DatePicker datePicker;
private TextView tvHeading;
private Button btnDone;
private String lastModifiedDate;
private String initialDate;
private boolean isStartDateToday;
private long currentDateInMS = 0;
private Context context;
private int noOfDaysBefore = 0;
public DatePickerDialog(Context context, DatePickerCallback callback, String date, String title, boolean isStartDateToday,int noOfDaysBefore) {
super(context);
this.context = context;
this.callback = callback;
this.date = date;
this.lastModifiedDate = date;
this.initialDate = date;
this.title = title;
this.isStartDateToday = isStartDateToday;
this.noOfDaysBefore = noOfDaysBefore;
}
public interface DatePickerCallback {
public void setDate(String date);
}
public static void showDatePickerDialog(Context context,DatePickerCallback callback,String date,String title,int numOfDaysBefore){
dialog = new DatePickerDialog(context, callback, date,title,false,numOfDaysBefore);
dialog.show();
}
public static void showDatePickerDialogStartDateToday(Context context,DatePickerCallback callback,String date,String title){
dialog = new DatePickerDialog(context, callback, date,title,true,0);
dialog.show();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.layout_datepicker);
getWindow().getAttributes().windowAnimations = R.style.animationdialog;
findAllIds();
setListener();
init(date);
}
private void findAllIds(){
tvHeading = (TextView)findViewById(R.id.tv_heading);
datePicker = (DatePicker)findViewById(R.id.datePicker);
btnDone = (Button)findViewById(R.id.btn_done);
tvHeading.setText(title);
}
private void setListener(){
btnDone.setOnClickListener(this);
}
private long getMilisecondsFromCalendar(int noOfDays){
SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyy HH:mm:ss");
String previousDate = CommonFunction.getDateBeforeOrAfterNoOfDays(
CommonFunction.getCurrentDate("ddMMyyyy HH:mm:ss"), noOfDaysBefore, "ddMMyyyy HH:mm:ss");
Date date;
Calendar calendar = Calendar.getInstance();
try {
date = sdf.parse(previousDate);
calendar.setTime(date);
} catch (ParseException e) {
e.printStackTrace();
}
return calendar.getTimeInMillis();
}
private void init(String date){
String date_str = CommonFunction.formatDate("yyyyMMdd", "dd MM yyyy", date);
String datearr[] = date_str.split(" ");
Calendar calendar = Calendar.getInstance();
calendar.set(Integer.parseInt(datearr[2]), Integer.parseInt(datearr[1]), Integer.parseInt(datearr[0]));
int iDay=calendar.get(Calendar.DATE);
int iMonth=calendar.get(Calendar.MONTH);
int iYear=calendar.get(Calendar.YEAR);
if(isStartDateToday){
datePicker.setMinDate(System.currentTimeMillis()-1000);
}else{
if(currentDateInMS == 0){
currentDateInMS = getMilisecondsFromCalendar(1);//Calendar.getInstance().getTimeInMillis();
}
datePicker.setMaxDate(currentDateInMS);
}
datePicker.init(iYear, iMonth-1, iDay, this);
datePicker.setDescendantFocusability(DatePicker.FOCUS_BLOCK_DESCENDANTS);
}
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
StringBuilder date = new StringBuilder();
date.append(year);
monthOfYear = monthOfYear +1;
if(monthOfYear < 10){
date.append("0"+monthOfYear+dayOfMonth);
}else{
date.append(monthOfYear).append(dayOfMonth);
}
if(isStartDateToday){
}else{
if(!isDateValid(date.toString())){
try{
init(lastModifiedDate);
}catch(Exception e){
e.printStackTrace();
}
return;
}
}
this.date = date.toString();
}
private boolean isDateValid(String date){
boolean flag = false;
String currentDate = CommonFunction.getCurrentDate("yyyyMMdd");
long days = CommonFunction.getNoOfDaysBetweenDate(currentDate, date, "yyyyMMdd");
// long days = CommonFunction.getNoOfDaysBetweendate(CommonFunction.formatDate("dd-MMM-yyyy", "ddMMyyyy", ), CommonFunction.formatDate("yyyyMMdd", "ddMMyyyy", date));
if(days <= 0){
flag = true;
lastModifiedDate = date;
}
return flag;
}
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.btn_done:
callback.setDate(this.date);
dialog.dismiss();
break;
}
}
}
and layout file is
