Android ListView with sticky headers

headerlistview's Issues

Can't use convertView in headers

The method

public View getRowView(int section, int row, View convertView, ViewGroup parent)

in the SectionAdapter class is always called with convertView and parent as null.

From HeaderListView.java line 262:

View header = mAdapter.getSectionHeaderView(actualSection, null, null);

This way, we cannot reuse inflated headers.

Also, since the parent is null, it is impossible to instantiate a LayoutInflater simply by calling LayoutInflater.from(parent.getContext()). One workaround for this is to pass a context when creating the adapter, and then getting the inflater from that context.

Dynamically add items instead of hard coded.

Be able to add items for array list or set individual strings. Example:

    ListView listview = (ListView) this.findViewById(R.id.listView1);
    NewAdapter adapter = new NewAdapter(this);
    // add("name","id");
    adapter.add("Section #1", "Section");
    adapter.add("Item #1", "Item");
    listview.setAdapter(adapter);

   // Adapter add() will see if it is a section or item and process it.
  add(String name, String id) {
  if(id.equals("Section") {
    // Set Section name and stuff
    // also set unclickable
  } else if (id.equals("Item") {
    // Set Item name and stuff
  }

Crash when returning to fragment as a tab. View with same id

This stackoverflow post has more details and the workaround: http://stackoverflow.com/questions/25807332/crash-when-returning-to-fragment-as-a-tab-view-with-same-id

With two tabs (A & B fragment using HeaderListView), when switching from B to A back to B, the app crashes with java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class android.widget.AbsListView$SavedState instead. This usually happens when two views of different type have the same id in the same hierarchy. This view's id is id/header_list_view. Make sure other views do not use the same id.

Other views are not using the same ID and to fix this issue I can listview.setId() in onCreateView to anything.

Publish the project as .aar to maven

I would love to see a .aar file published to maven, so that it is even more easy to use!

I want to pass the cursor in section adapter and read the data from it. How can i achieve this?

keep scroll position

thank for the lib first of all , i have a question is there anyway to keep scroll position after some new values added to the listview?

Visual Glitch when implementing HeaderListView in tabs/fragments

Hi,

I have created a tabView, each tab being a fragment containing the same HeaderListView.
Consider the following case:
Tab 0: Scroll down so that one "section" overlays on the screen
Swipe right
Tab 1: Do nothing
Swipe right
Tab 2: Do nothing
Swipe left
Tab 1: Do nothing
Swipe left
back to Tab 0.
The overlayed "section" will have disappeared (acting like a regular list would act). When starting scrolling, it will automatically reappear.

I found this behavior happening only when you have 3 or more Tabs. It seems that when you have 2 only, they are kept in memory, but when you have 3, only the direct neighbors will be kept in memory. Therefore, I think when the HeaderListView get regenerated, there is a visual glitch happening.

Thanks for this great library!

Scrollbar visible on launch

The full scrollbar is visible on application first launch. For example:

This is because the scrollbar is updated on updateScrollBar(), which is only called during onScroll(). This is a big issue when the number of rows don't fill the screen, so there is no need for scrolling and onScroll() is never called.

An easy fix (the way I did it) is to start with the scrollbar hidden (make mScrollView invisible during HeaderListView.init()

Hiding the Toolbar (not ActionBar) when you scroll

Is there any way to hide the Toolbar when you scroll ? If its possible how would it be done smoothly ?

Fast scroll

Is there a way to disable the fast scroll? In case of the fast scroll, HeaderListView crashes the application.

Any news on fast scroll implementation?

Thanks

getSectionHeaderView method doesn't work

Hello,
I tried to implement this library in my project as your demo but getSectionHeaderView did not work or I missed something. I share screenshot and implemented gist file. Thank you for your help.

Ability to setOnScrollListener

This is useful for infinite scrolling.

Is there any option for making search?

I want to have a search box to find the value in the list. Is it possible?

I read the source code, HeaderListView class seems do no have this kind of option

Whats the point of InternalListView?

Just browsing through the code and was wondering what the point of InternalListView since it doesn't do anything.

Add support for infinite scrolling

Scroll up force SwipeRefreshLayout to refresh

Scroll up force SwipeRefreshLayout to refresh, however, scroll down works properlly

java.lang.NoSuchMethodError in sample

Hello,

I just imported sample project in android studio to run on a GT-S5830 Android 2.3.3 (API10).
Sample Application crash when entering onStickyHeaderChanged method using setAlpha :

sample.TestActivity.onStickyHeaderChanged(TestActivity.java:203)

When removing this line for test, listView can scroll down, but can't scroll back to the top.

Can you fix this to get good practices for making a fully fonctional implementation ?
Many thx !

addHeaderView() not working correctly

When I add a View to the Header, onRowItemClick() parameters aren't correct

SectionAdapter.numberOfRows gets section == -1

When scrolling variable section==-1 is passed method numberOfRows.
Correct section numbers are also passed to this method, and it is not a big problem to check section in method body but this -1 is very unexpected.

Also, in Demo example we cannot watch such behavior cos` for every section (whatever it is) method returns 35, even for section -1

Headers incorrect when device rotated

If a list is partially scrolled and then the device rotated, the heading appears in the wrong place (e.g. half way down the screen). The header resets when scrolled to the top or past another heading.

first header remains constant when new adapter set

i need to change my data frequently, so each time i create a new adapter with new data, the data shows well, the problem is the previous header still stood and won't change according to new data.

How to change background color in RowView

Hi, firstly, congratulations for great work in the HeaderListView!!
My environment is ADT eclipse + java 7 + android 4.4.2. I'm using Navigation-drawer-page-sliding-tab-strip library and in the PageContentStripFragment class in onCreateView method I have:
HeaderListView list = new HeaderListView(getActivity(),null);
list.setAdapter(new ListViewSectionAdapter());
It's working!!
Hence, ListViewSectionAdapter is a subclass of SectionAdapter. In override getRowView method I inflated my layout called "custom_row_list".
So, i want to set custom background color when RowItem selected.
I did to set drawable selector and custom_row_list.xml:
android:background="@drawable/list_selector"

But not working!! What I doing wrong??

Thanks!

numberOfCellsBeforeSection has performance issue.

Hi Applidium,

The method numberOfCellsBeforeSection may have performance issue if the listview have lots sections. It is being called many times during scrolling. I am considering to extend the method and build a cache for it. When data set is changed, wipe the cache.

Populating header and row dynamically

Hello how can i inject the items below inside SectionAdapter ?

    List<Item> items = new ArrayList<Item>();
    items.add(new Header("Header 1"));
    items.add(new ListItem("Text 1", "Rabble rabble"));
    items.add(new ListItem("Text 2", "Rabble rabble"));
    items.add(new ListItem("Text 3", "Rabble rabble"));
    items.add(new ListItem("Text 4", "Rabble rabble"));

    items.add(new Header("Header 2"));
    items.add(new ListItem("Text 5", "Rabble rabble"));
    items.add(new ListItem("Text 6", "Rabble rabble"));
    items.add(new ListItem("Text 7", "Rabble rabble"));
    items.add(new ListItem("Text 8", "Rabble rabble"));
    items.add(new ListItem("Text 9", "Rabble rabble"));
    items.add(new ListItem("Text 10", "Rabble rabble"));

Add to Maven Central or JCenter

This would make getting started and updating versions in projects much easier.

Programmatically scroll to section header

Is there any way to programmatically scroll to a particular section header? I have buttons along the top of my ListView which represent the different section headers, and I want to scroll to the appropriate section upon tapping them. Is this possible?

Could not find class

I have added the project in my workspace and added the project to the build path, but I still get the "could not find class com.applidium.headerlistview.HeaderlistView. I am not sure what else needs to be done, although I am able to run the DEMO.

Adding Custom OnScrollListener forcing the section header scrolling

Hi,

I have added my custom OnScrollListener which is AbsListView.OnScrolllistener on HeaderListView ,because its own onscrolllistener is required for minimum Api LEVEL 23(my minimum is 15).
It is forcing the section headers scrolling.I want to fix the sectional headrers.Kindly give me some advice.

Below is my custom implementation:-
MyClass implements AbsListView.OnScrollListener
{
@Bind(R.id.receipt_list)
HeaderListView mReceiptsList;

    mReceiptsList.getListView().setOnScrollListener(this);

@OverRide
public void onScrollStateChanged(AbsListView view, int scrollState) {
this.currentScrollState = scrollState;
this.isScrollCompleted();//the method to detect scroll completion
}

@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
    this.currentFirstVisibleItem = firstVisibleItem;
    this.currentVisibleItemCount = visibleItemCount;
    this.totalItemCount = totalItemCount;
}

   /***By this methos I detect if there's been a scroll which has completed***/
private void isScrollCompleted() {
    if (this.currentVisibleItemCount > 0 && this.currentScrollState == SCROLL_STATE_IDLE && this.totalItemCount == (currentFirstVisibleItem + currentVisibleItemCount)) {
 
        if(canLoad) { //class variables to manipulate the data
            pageNumber =pageNumber +1;
            refreshScreen();
        }
    }
}

}

Demo crashing - patched

I just put in a patch for this issue in the Demo. There was a problem where views would be recycled, but they were for the wrong type of view. The issue caused a null reference to be returned for R.id.text2when recycling a convertView that had originally been a TextView.

First header issue

Hi there!
I am encountering an issue using your library.
As you can see in the following screenshots only the first header "additional toppings" scrolls as like as the children. After scrolling it a bit it gets repositioned in the correct way (sticky at the top).
Do you have any idea how to fix it?

I'm using the listview inside a custom dialog.

Is it possible to stop the scrolling?

I tried setEnabled(False) and also setClickable(False) but they don't work.
The thing is I need to stop the list from being scrollable when I press on a list item.

Section with dynamic rows

Hello, i am working on an app. I want to display the rows with dynamic size.
But, as your function
@OverRide
public int numberOfRows(int section)
{
34;
}

Which creates 35 rows in each section.
I want 2 rows in first section, 5 rows in second section.. like wise..
How can i achieve this?
Thanks in advance..!! :)

documentation

You should add to the documentation that we should always override getSectionHeaderViewTypeCount

because I only have 1 type of header so I tought I didn't need it... and have been debugging for some hours...

everything else rocks! thanks :D

No highlight/ripple

There is no highlight or ripple effect when an item in the row is click.
A normal listview would have a highlight or a ripple effect (> L) when they are clicked.

Is it possible to set a listener for the scrolling?

I have the keyboard up, for a search view, and I want it to disappear when I scroll through the list, is this possible?

Divider between header and row

I'm using header and one row in section. Header contains title and the row contains image. I've noticed gray line , that looks like a divider, above image view which is located in row since it goes under the header as the row is scrolled. Any idea how to remove this?

HeaderListViewOnScrollListener.updateScrollBar

I have imported your project and created a new project using the library given. It works fine till the values are static i have the setContentView() set as HeaderListview id. But when i change the from listview to HeaderListview in xml file it gives me the following error.
" java.lang.ArithmeticException: / by zero at com.applidium.headerlistview.HeaderListView$HeaderListViewOnScrollListener.updateScrollBar(HeaderListView.java:215) at com.applidium.headerlistview.HeaderListView$HeaderListViewOnScrollListener.onScroll(HeaderListView.java:115) "

Please help me in solving this error.
I need to setContentView() a different layout as i have other elements also on the same xml file.

First section without any row items

Thanks for the Fix #9 Tokou. Unfortunately I am still experiencing some issues if the FIRST section has no rows. In this case the second section header is displayed twice as soon as I scroll down the list. From what I understand, this behaviour does not occur if I disable the changes from Fix #21 .

[Question] Best way to refresh listview?

Hey there.

I'm loading in data dynamically like so..

 ParseQuery<Assignment> query = ParseQuery.getQuery(Assignment.class);
    query.whereEqualTo("owner", ParseUser.getCurrentUser());
    query.fromLocalDatastore();
    query.findInBackground(new FindCallback<Assignment>() {
        @Override
        public void done(List<Assignment> results, ParseException e) {
            finishedList = new ArrayList<Assignment>();
            unfinishedList = new ArrayList<Assignment>();
            completed=0;
            uncomplete=0;
            for(Assignment a: results){
                Log.d("Assignment", a.getName());
                if(a.getComplete()){
                    finishedList.add(a);
                    completed++;
                }
                else{
                    unfinishedList.add(a);
                    uncomplete++;
                }
            }
            notifyDataSetChanged();
            //if(mListener!=null)setListAdapter(new ArrayAdapter<Assignment>(getActivity(),
            //       android.R.layout.simple_list_item_1, android.R.id.text1, results));
        }
     });

The problem is that the app crashes at notifyDataSetChanged();

I have attached the entire file other then the actual row rendering. If i remove notifydatasetchanged it will work but will not show the rows which defeats the point.

Non Sticky Headers

How to make listView headers not stick

onRowItemClick(...) not called

Thanks for your fantastic work, I do enjoy working with HeaderListView a lot. Nevertheless I have one problem related to click events.

I implemented the onRowItemClick(...) method in my Section Adapter. Unfortunately it is not called and I don't know why. Do I need to "attach" it to the HeaderListView?

Please let me know if you need further information.

It would be very helpful if you would include an example for this in the HeaderListViewDemo.

Thank you & best regards,
Sebastian

How to disable scrolling ?

how to use HeaderListView with a CalendarPickerView

Hello,
I need to use HeaderListView with a CalendarPickerView to have a stickyscroll for the headers of my calender(months).
This is what I did :
I changed the inheritence of CalendarPickerView class from ListView to HeaderListView (changed all the methods to keep it working). Then, I created my CalendarAdapter class that extends from SectionAdapter class (but I didn't implements the abstract methods ).

I don't know what I have to do after that ! Thanks !

Sections without any row items

I am currently using the HeaderListView to display data where some sections might have no row items (the section header is and should be shown regardless of this fact). Now, when I scroll down through the HeaderListView I am experiencing a weird bug for those section headers without any rows. As soon as they begin to exit the visible area, it is overridden by a previously shown section header view.

I can provide some screenshots to clarify the issue if wanted.

Duplicate scrollbars w/ Fast Scrolling

I realize that Fast Scrolling is a feature that is to-be implemented, but is there a work-around to fix this problem as of now?

Switching Header Label values

I'm showing a ListView with 3 sort buttons above it (Name, Country, Age). When sorting changes, I'm updating the HeaderListview like this:
((PeopleSectionedAdapter) listView.getAdapter()).setLinkedPeopleMap(indicesBR.get("name"));
((PeopleSectionedAdapter) listView.getAdapter()).notifyDataSetChanged();
or
((PeopleSectionedAdapter) listView.getAdapter()).setLinkedPeopleMap(indicesBR.get("country"));
((PeopleSectionedAdapter) listView.getAdapter()).notifyDataSetChanged();
or
((PeopleSectionedAdapter) listView.getAdapter()).setLinkedPeopleMap(indicesBR.get("age"));
((PeopleSectionedAdapter) listView.getAdapter()).notifyDataSetChanged();

Actually it works, but when I havent scrolled below the 2nd Header, the currently active header doesn't get changed at all. E.g. I have selected "Name" and I scrolled down just a very small amount - then the currently active header still says "A", while the next visible header displays the correct title. I'd have to scroll down until the next header gets active and then scroll back to update the previously active one. This problem doesn't occur if I don't do any scrolling at all.
How can I fix this?
