ListView not scrolling #40

pmessina · 2016-11-05T20:09:34Z

I am working with version 2 of your SectionCursorAdapter library, and I'm having trouble with my listView not scrolling. I ran your sample and it scrolls fine. I reverted back to version 1 of your library, but I have the same issues. The views inflate fine, and I'm retrieving the right amount of cursors. Here's my implementation:

package com.pirateman.recruitercallsinterviews;

private static String eventTimeZone = CalendarContract.Events.EVENT_TIMEZONE;
private static String eventAllDay = CalendarContract.Events.ALL_DAY;

public InterviewsCursorAdapter(Context context, Cursor cursor)
{
    super(context, cursor, 0, R.layout.interviews_date_tv_separator, R.layout.interviews_lv_row_layout);

{
    DateTimeFormatter dateFormatter = DateTimeFormat.longDate();
    String eventStart = cursor.getString(cursor.getColumnIndex(eventStartCol));

    return dateFormatter.print(Long.parseLong(eventStart));
}

{
    return new InterviewDateViewHolder(sectionView);
}

{
    sectionViewHolder.interviewDate.setOnClickListener(null);
    sectionViewHolder.interviewDate.setText(section);
}

    return new InterviewViewHolder(itemView);
}

        String eventStartTF = timeFormatter.print(startTimeDT);
        String eventEndTF = timeFormatter.print(endTimeDT);

It sounds like there is something wrong with you View hierarchy. Do you
have something blocking your ListView that is click able? In other words,
is there something else intercepting the touch events? Is the ListView
consuming or ignoring touchevents somewhere else? That's are going guess
but my gut says that the adapter is not fault as it does not control
scrolling.

I discovered that the problem was with the ListView. It will not work with CoordinatorLayout, but works fine with LinearLayout. Are you guys still working on supporting RecyclerView? I hear that would work with CoordinatorLayout.

MinceMan · 2016-11-07T15:59:38Z

Yes version 3 has full support but as I no longer work at this company I
cannot release it myself. I would recommend using it. The Readme has been
mostly updated as well. That said there are still a bugs with it.
