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

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.

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.

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.

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?

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.

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.

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"));

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 !

Hi, I wanted to try your library but I think your local environnement configuration was not like mine and I never get it to work. To avoid that I re-configure the entire project with gradle and I include the gradle wrapper. I also removed some eclipse files and some old maven configuration files (I guess). I hope it can help! :-). In the future I will create a dependancy in a mvn repo on my github to be able to use it without having to include the source code in my project.

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();
        }
    }
}

}

App crashes, Reason: java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.ViewGroup$LayoutParams android.view.View.getLayoutParams()' on a null object reference

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.
