Re: Question about setting weekview event

Hello,

This is with reference to the issue I opened earlier, with the same title. I cannot reopen the issue, because it was not closed by me. Hence opening a new issue:

Question : Is there a way to set the list of events in WeekView other than returning List of WeekViewEvents in onMonthChange() ?

Your solution:

Currently the week view does not provide a ready-made solution for async event loading. But there is a simple hack. Use the following code to achieve what you want.

@Override public List onMonthChange(int newYear, int newMonth) { // Populate the week view with some events. List events = new ArrayList();

// Fetch events for the date user selected.
fetchEventsinBackground();

}

// Callback when fetchEvents finishes. public void setEventList(Activity activity, final List eventModels) {

// Hide the progress dialog.
if(mProgressDialog != null && mProgressDialog.isShowing()) {
    mProgressDialog.dismiss();
}

// Refresh the week view.
activity.runOnUiThread(new Runnable() {
    @Override
    public void run() {
        // Store the returned events in a global variable for later use.
        mEventModels = eventModels;

        // This line will trigger the method 'onMonthChange()' again.
        mWeekView.notifyDatasetChanged();
    }
});

}

@Override public List<WeekViewEvent> onMonthChange(int year, int month) { // TODO Be sure to check if the variables year and month equals the year and month of the events of mEventModels. return getWeekViewEventsFromEventModels(mEventModels); }

Thank you for the response, however it did not work for me.

Java doesn’t support 2 methods with same signature, so I can’t have something like this in the same class:

@Override public List<WeekViewEvent> onMonthChange(int year, int month) { // TODO Be sure to check if the variables year and month equals the year and month of the events of mEventModels. return getWeekViewEventsFromEventModels(mEventModels); } @Override public List onMonthChange(int newYear, int newMonth) { // Populate the week view with some events. List events = new ArrayList();

// Fetch events for the date user selected.
fetchEventsinBackground();

} If mWeekView.notifyDatasetChanged(); triggers onMonthChange() again, then it results in an infinite loop with fetchEventsinBackground() being called again & again!

Is there a better way out ? Thanks for all the help!

Sorry. I should have been more precise about the code. Here, check out the new code.

private List<EventModel> mEventModels = new ArrayList<EventModel>();

@Override
public List onMonthChange(int newYear, int newMonth) {
    // Check if you've already fetched the events for this month on the previous call.
    if (mEventModels.size() == 0 || !containsEvents(mEventModels, newYear, newMonth)) {
        // Fetch events for the date user selected.
        fetchEventsInBackground();
        return new ArrayList<WeekViewEvent>();
    }

    // If we've reached up to this point then it means we've already fetched the data in the previous call.
    return getWeekViewEventsFromEventModels(mEventModels, year, month);
}

// Callback when fetchEvents finishes.
public void setEventList(Activity activity, final List<EventModel> eventModels) {

    // Hide the progress dialog.
    if(mProgressDialog != null && mProgressDialog.isShowing()) {
        mProgressDialog.dismiss();
    }

    // Refresh the week view.
    activity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            // Store the returned events in a global variable for later use.
            mEventModels.addAll(eventModels);

            // This line will trigger the method 'onMonthChange()' again.
            mWeekView.notifyDatasetChanged();
        }
    });
}

private boolean containsEvents(List eventModels, year, month) {
    // TODO Do a search in the 'eventModels' list to see if it contains the events of the given 'year' and 'month'. If not then return false.
}


private boolean getWeekViewEventsFromEventModels(List eventModels, year, month) {
    // TODO Filter the events from the eventModels by year and month. It would be good idea if you remove the events that are not in the desired range (i.e. where the month is not month+-1). This will release some memory.
}

@waynem81 You’ll probably have to convert your bean to an instance of WeekViewEvent
