here I able to see all events while clicking on a particular date,but my requirement is also show the dates with bold style or any other color view that containing events without clicking gridview items.My adapter class as follows:::

refreshDays();
}
public void setItems(ArrayList<String> items) {
for (int i = 0; i != items.size(); i++) {

items.set(i, "0" + items.get(i));
}
}

// taking last part of date. ie; 2 from 2012-12-02

// checking whether the day is in current month or not.

// setting offdays to white color.

// show icon if date is not empty and it exists in the items array

pmonth = (GregorianCalendar) month.clone();
// month start day. ie; sun, mon, etc
firstDay = month.get(Calendar.DAY_OF_WEEK);
// finding number of weeks in current month.
maxWeeknumber = month.getActualMaximum(Calendar.WEEK_OF_MONTH);
// allocating maximum row number for the gridview.
mnthlength = maxWeeknumber * 7;
maxP = getMaxP(); // previous month maximum day 31,30....
calMaxP = maxP - (firstDay - 1);// calendar offday starting 24,25 ...
/**
* Calendar instance for getting a complete gridview including the three
* month's (previous,current,next) dates.
*/
pmonthmaxset = (GregorianCalendar) pmonth.clone();
/**
* setting the start date as previous month's required date.
*/
pmonthmaxset.set(Calendar.DAY_OF_MONTH, calMaxP + 1);
/**
* filling calendar gridview.
*/
for (int n = 0; n < mnthlength; n++) {
itemvalue = df.format(pmonthmaxset.getTime());
pmonthmaxset.add(Calendar.DATE, 1);
dayString.add(itemvalue);
}
}
private int getMaxP() {
int maxP;
if (month.get(Calendar.MONTH) == month
.getActualMinimum(Calendar.MONTH)) {
pmonth.set((month.get(Calendar.YEAR) - 1),
month.getActualMaximum(Calendar.MONTH), 1);
} else {
pmonth.set(Calendar.MONTH,
month.get(Calendar.MONTH) - 1);
}
maxP = pmonth.getActualMaximum(Calendar.DAY_OF_MONTH);
return maxP;
}
}

Atlast I had already solved my problem changing my Runnable calendar updater as follows:
public Runnable calendarUpdater = new Runnable() {
#Override
public void run()
{
items.clear();
// Print dates of the current week
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
String itemvalue;
for (int i = 0; i < 7; i++)
{
itemvalue = df.format(itemmonth.getTime());
itemmonth.add(Calendar.DATE, 1);
items.add("2014-12-08");
items.add("2014-12-04");
items.add("2014-11-07");
items.add("2014-11-08");
}
adapter.setItems(items);
adapter.notifyDataSetChanged();
}
};
Now I can see the events without clicking gridView items what I want.Thanx all of you guys for your kind cooperation in this regard. but now issue is how can I also show this event on android google calendar.

How to pass or get the spinner value to a string in android?

I am trying to pass the value from spinner.setOnItemSelectedListener to a string that contains date string. I have two spinners month and year, here I am showing only for month spinner because if I get the solution for month spinner then it will be same for year as well.
month_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (parent.getId() == R.id.month_spinner){
seltmont = parent.getSelectedItem().toString();
Toast.makeText(MainActivity.this, "Selected Month: " + seltmont, Toast.LENGTH_SHORT).show();
textviewMonth.setText(seltmont);
setMonthView();
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
I have tried to access the spinner value like this:- String month = month_spinner.getSelectedItem().toString();
and try to pass the spinner onItemSelectListener value to combinedString string variable like this:-
combinedString = "01/" + month + "/" + year ;
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MMMM/yyyy");
selectdate = LocalDate.parse(combinedString, formatter);
I get the default value in the combined string that is already preselected in the spinner but
when user try to change the default value that is shown in spinner it does not change the value. It gives null value in the combinedString.
Can anyone help me How to pass the value from onItemSelectListener to combinedString
Is it because of the scope of a method (' { } ') or is it because of private or public variable declaration.
Please help.

I have attached two images of the output:

Declare selectdate as static public static LocalDate selectdate;
Create a method named getSelectDate and call it to get changed value , such as inside onCreate, inside onItemSelected of month_spinner and spinYear.
private void getSelectDate() {
//added
String month = month_spinner.getSelectedItem().toString();
String year = spinYear.getSelectedItem().toString();

To get "dd/MM/yyyy" this format use DateTimeFormatter.ofPattern("dd/MM/yyyy", Locale.ENGLISH).format(selectdate); , no other changes need .
To test -
#RequiresApi(api = Build.VERSION_CODES.O)
private void updateView() {
// combinedString = "01/" + mon + "/" + year ;
//not working
String mon = textviewMonth.getText().toString();
// Log.d("month","code is going here");
// textviewYearnMonth.setText(mon);
// Log.d("month","code cross the textviewYearnMonth");
textviewYearnMonth.setText(DateTimeFormatter.ofPattern("dd/MM/yyyy", Locale.ENGLISH).format(selectdate));
}
In the onItemSelected callbacks, just use the data sources with the position variable and you'll get it. For example for months spinner:
month_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (parent.getId() == R.id.month_spinner){
seltmont = months[position]; // ATTENTION HERE
Toast.makeText(MainActivity.this, "Selected Month: " + seltmont, Toast.LENGTH_SHORT).show();
textviewMonth.setText(seltmont);
setMonthView();
}
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
Do the same for all the spinner listeners.

This is the above code please go through it and let me know if any clarifications are required. I cannot able to set "itemsTotal" value to "noOfIttems" textview. I have added the comments. Please help me in solving this issue.
Thanks in advance.
Please check your noOfItems textView's id. TextView is null.

The problem is that you saved the Activity reference in onCreateView, and also tried to dereference it.
Error can be from following lines in your code :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//your code ...
app = getActivity(); //getActivity() can return null, so app will be null
//your code ...
map = ((MapFragment) app.getFragmentManager().findFragmentById(R.id.map)).getMap(); //possible NPE
Correct approach is save the Activity reference in onAttach, and dereference it.
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
app = activity; //correct place to get activity reference
//your code ...
map = ((MapFragment) app.getFragmentManager().findFragmentById(R.id.map)).getMap();
}
