I have the following layout

   <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/background_gray"
        android:focusableInTouchMode="true"
        >
                <it.sephiroth.android.library.widget.HListView
                    android:id="@+id/storefront_gallery_list"
                    android:layout_width="match_parent"
                    android:layout_height="@dimen/gallery_image_side"
                    android:divider="@android:color/transparent"
                    app:dividerWidth="@dimen/spacing_normal"
                    android:paddingTop="@dimen/spacing_normal"
                    android:background="@color/background_gray"
                    />
    </RelativeLayout>

I'm no longer able to compile this. I get the following Gradle error:

Output:
/Users/user/dev/mobile/test-project/TestProj/build/res/all/debug/layout/activity_test.xml:123: error: No resource identifier found for attribute 'dividerWidth' in package 'com.test.testproj'

There seems to be an issue with

app:dividerWidth="@dimen/spacing_normal"

and

xmlns:app="http://schemas.android.com/apk/res-auto"

Should I be including that a different way? I ended up having to programmatically set the dividerWidth attribute. This started happening not too long ago. I had to clean my gradle cache ~/.gradle and maven cache ~/.m2 for it to manifest itself on my local machine in case that's of relevance.

Hi, I wanted to ask is there something similar like AbsListView.smoothScrollBy?

I went through the code but didn't found any obvious way to scroll view programmatically.

My goal is to add some automatic scrolling when user finish it's manual scrolling to adjust alignment of the items, so the first I item will be fully visible (not half of a view).

Thank you for any answers.

Hi,

Just wondering if this is possible with the HorizontalListView class? Also, I have the HorizontalVariableListView inside a regular ListView - I wanted to know how I can send the up and down touch/scroll events to the parent ListView - currently - if I try and scroll the main (parent) listview up and down while touching somewhere inside the HorizontalVariableListView the touch seems to be lost and nothing happens - if that event (if you can tell me what and how to get the event even) can be trapped and somehow bubbled up to the parent listView that would be great.

Thanks for an excellent library,

Warm Regards,

Shabbir

I use HorizontalVariableListView.OnScrollFinishedListener on master in work ok,
but in developtment tags,it doesn`t work.

so help me please !

Im trying to implement this on a fragment but Im not getting any display. there is something I should change?

=(( why did you break compatibility

AdapterView.setOnItemClickListener
and
HorizontalVariableListView.setOnItemClick>>ed<<Listener

it's not trivial to find this little difference, please don't do this in the future.

I'm using "HListView.smoothScrollToPositionFromLeft(int position, int offset)", I tested on Android 4.4 and is working fine, but in HTC WIldfire S with 2.3.3 only works sometimes.

Would it be possible to get a JAR file for this rather than copying all the source files into my project?

I use the development branch in my project to realize the horizontal listview. But,when I invoke the notifyDataSetReplaced and notifyDataSetAdded how I can smooth scroll to specified position of the adapter in development branch. I just want the specified position view show in the first position of the visible rect。I will be happy to getting your help, thanks a lot.

In my application I have a number of fragments, most of which contain a ListView, including one with an HListView. There are two paths to the fragment with the HListView - one works without issue, and the other throws a ClassCastException. I've spent several hours trying to figure out the cause, but I can't find an answer in my code. I am not importing either of these LayoutParams, and I've made sure the ids of the layouts and layout objects are unique. Below is the log which captures the exception. Any ideas?

Hi,
When list item changed in adapter, I called notifyDatasetChanged to ask the list redraw, but it's empty then, is it a bug ? or I have to use another method ?

Could you please add smoothScrollTo method in your Demo code?

I changed the followings in your demo code:

1. change item width to 100px in view1.xml
2. I want to scroll to the 31th item, so in the MainActivity.java added the following line at the end of onCreate method, then the scroll bar is empty now.

mList.smoothScrollTo(30*100);

scrollTo properly scrolls to the correct position but does not request views from the newly visible adapter items. For the time being I have overridden scrollTo to forward to smoothScrollBy with a duration of 0.

Hey all,

First of all, i want to thank you Alessandro for this lovely component. I have also tested the dev-smart's HorizontalListView, and i am getting much better results with your view.

Unfortunately though, I am suffering from one main problem - while i can scroll nice and smooth, i can't catch onItemClicked events. I have followed the example you've provided in the demo activity. More frustrating is the fact that when i test the same views and layouts i am using, with android's native ListView, and dev-smart's HLV it actually works. I made sure i was using the correct classed, but still can't get it to work.

Would appreciate if you guys could take a look at my code, and see whether i am doing something terribly catastrophic. After looking at it for the entire day, i am positive i am missing something very fundamental

Hi, what is the reason this library support only android 2.3+ ?
Is there any chance to add support for android 2.2 too?

I am having trouble setting the cell selected colour.

I have tried in XML by setting the listSelector attribute as follows:

        android:listSelector="@drawable/selected_background"

The selected_background is a simple shape containing a solid colour

Unfortunately the item selected colour is still the standard Holo Light blue.

It seems in the standard ListView there is a setSelector method. However, this does not seem to be included in the HVLV.

I must be missing something very simple.... :)

Hi
Is there any set*** with horizontal scroll bar?

I was unable to build event Demo project via ant build (debug target).

Root cause of error was strange:
.......
clean:
[getlibpath] Library dependencies:
[getlibpath]
[getlibpath] ------------------
[getlibpath] Ordered libraries:

BUILD FAILED
/Users/ak/Development/android-sdk-macosx/tools/ant/build.xml:471: The following error occurred while executing this line:
/Users/ak/Downloads/HorizontalVariableListView-master/HorizontalVariableListView/build.xml:50: Source resource does not exist: /Users/ak/Downloads/project.properties

SOLUTION that I've researched:
Please remove entry
<loadproperties srcFile="../../project.properties" />

from this file:
HorizontalVariableListView/build.xml:50

The image hlv_overscroll_edge.png varies significantly in its density-independent (dip) size across the various density versions: drawable-mdpi/hlv_overscroll_edge.png: 522x12 dp (522x12 px), drawable-xhdpi/hlv_overscroll_edge.png: 522x12 dp (1044x24 px), drawable-hdpi/hlv_overscroll_edge.png: 522x12 dp (783x18 px), drawable-ldpi/hlv_overscroll_edge.png: 320x11 dp (240x8 px)

Got this exception when rotate some devices more then one time. I did solve it just checking if mDataSetObserver is not null before calling mAdapter.unregisterDataSetObserver( mDataSetObserver ) on onDetachedFromWindow method (AbsHListView class).

Invoking notifyDataSetChanged() changes position in HorizontalVariableListView to 0. If I remember normal ListView remembers scroll state.

I think the problem is caused by:

/** The m data observer. */
private DataSetObserver mDataObserver = new DataSetObserver() {

    @Override
    public void onChanged() {
        synchronized ( HorizontalVariableListView.this ) {
            mAdapterItemCount = mAdapter.getCount();
        }
        Log.i( LOG_TAG, "onChanged(2): " + mAdapterItemCount );
        invalidate();
        reset();
    }

    @Override
    public void onInvalidated() {
        mAdapterItemCount = mAdapter.getCount();
        Log.i( LOG_TAG, "onInvalidated(2): " + mAdapterItemCount );
        invalidate();
        reset();
    }
};

and:

/**
 * Reset.
 */
private synchronized void reset() {
    mCurrentX = 0;
    initView();
    removeAllViewsInLayout();
    mForceLayout = true;
    requestLayout();
}

how to change it so position is kept?

Hello,

I'm trying to implement a HorizontalVariableListView with static hights and variable width of the Images. But the width of the ImageView ( from "detail_view.xml") is the same for the whole list.

It seams that the width is calculatetd/mesured from the first child in the list and all other childs have the same width --> the images are croped...

Can you help me with this issue.
Thanks in advance!

I have normal listview. Listview don't have divider. For test, bind each item listview with colored textview (red and blue). All ok. Don't see vertical divider between items.
Next: render at each listview item HListView (as with TextView also set background for HListView: red/blue). And now see some bottom padding at each item. Why?

.

if the item of the list has layout_height="match_parent" is behaving like "wrap_content".

I found a hack to fix until is not fixed in the library.

if you use a RelativeLayout as wrapper with layout_height="match_parent", it is working then.

Hi,

I use HorizontalVariableListView inside scrollview.It can't move up and down at the touch horizanallistview.

regard
Kit

When I use BadeAdapter and override getViewTypeCount() and getItemViewType() in this way:

@Override
public int getItemViewType(int position) {
    return position;
}
@Override
public int getViewTypeCount() {
    items.size() 
}

Then I get an error:

I suspect that library stores old value of getViewTypeCount() and doesn't update it after notifyDataSetChanged();

I am trying to use this widget in a Google TV project stacking HorizontalListViews one on top of another. I can't seem to get the Demo to work with trackpad/D-pad that google tv supports.
Ideally d-pad should cause the items to get focus and left/right should scroll the list horizontally.

I have a lot of large Images in my HorizontalVariableListView.

I debugged my App with DDMS Logcat and i see that the memory is continusliy growing when scrolling trough the list (this is of course, becaus the other images get lazy loaded). But in the official Android List View, the elements that are outside the screen (at least - that are a certain amout of space away from the screen bounds) are deleted/recycled from memory.

How can I achieve this with HorizontalVariableListView?
Beacuse soon or later I will run into a OutOfMemory Exeption.

Thanks for support!

Hello,

I have a problem filtering the list. If for example I have a 200 elements list and I filter it to 10 notifying the adapter all works well only that when fling to the end of the list it scroll way over the end of the list in white space.

Thank you.

The Android Gradle Plugin allows you to rename the App package, which is convenient for installing your debug and release apps on the same device.

I've traced it down to this line: https://github.com/sephiroth74/HorizontalVariableListView/blob/master/library/src/it/sephiroth/android/library/widget/AbsHListView.java#L5794

See https://groups.google.com/forum/?fromgroups=#!topic/adt-dev/cqdjG2TuM-I

from Xavier Ducrohet:

They make the assumption that the package name of the app is the same as the R class. This really is not correct. While the previous build system somewhat implied this, aapt always had the feature to generate the R class in a different package.

Thinking about it there really is no current way to query the app for the package of the R class. It'd have to be provided to the library.

Hello
I try to set layout_height = wrap_content to the horizontalvariablelistview who content only one listview and is not work. I have space vertical between my listview and your horizontalvariablelistview. Could you help me to do that please?

Would it be possible to implement a setDivider method like the standard listView?

Hello, thank you for your work. It looks very nice. My question is, can the left padding be changed? At the end of the list it's always a distance but on the left it starts from left with no padding or margin

if the list is very long and smoothScrollTo the end of the list makes the list crashed.

It seems that right padding means nothing for horizontal list view, can someone explain me how to add right padding to layout process?

When using HListView in the editor, it throws the following exception, preventing it from being previewed.

java.lang.IllegalStateException: Cannot find resource 'hlv_overscroll_edge'
at it.sephiroth.android.library.widget.EdgeEffect.(EdgeEffect.java:144)
at it.sephiroth.android.library.widget.AbsHListView.setOverScrollMode(AbsHListView.java:723)

I have successfully added the horizontal list view as a header to a standard list view. However, I am unable to get the horizontal view to register any click events.

I have implemented the OnItemClickedListener and OnItemSelectedListener as in the example so I guess the issue is related to it being a header view. Wehn inflating the header view and adding it I have tried to tried setting the isSelectable parameter to true and false both seem to have no effect.

           listView.addHeaderView(header, null, false);

I also call

                       listView.setItemsCanFocus(true);

after adding the header view

I have also tried adding

          android:descendantFocusability="afterDescendants"

To the header view to try and force the horizontal list view to get focus first. Any ideas?

I'm using this control to show a list of ToggleButtons but only a ToggleButton can be active at a time. When the application starts everything is OK because none ToggleButton is pressed, but if I press any of them you can count 5 or 6 and the next ToggleButton in the list will be checked too, it is like a pattern, next 5 or 6 ToggleButton will be checked again.

Any ideas please.

Greetings

I'm getting conflicts with android-support-v4.jar among other errors.

This is not bug. But may be anybody help.
If use ViewPager and at any page (fragment) use HListView, then on devices with sdk < 14 horizontal scrolling will be not work. Instead will be scroll to next page.
This is error of ViewPager.
Fix at SO: http://stackoverflow.com/questions/6920137/android-viewpager-and-horizontalscrollview/11706454#11706454

I have HorizontalVariableListView in Fragment. Every item in adapter inflates different view.

• I open the fragment. Fragment is added to backstack. HVLV is loaded. Visible items are loaded.

• I switch to different fragment. OnDestroyView of the 1st fragment does removeAllViews();

• I go back to 1st fragment. Its fetched with findFragmentByTag() from backstack. When it happens onCreate() is not invoked because fragment was not destroyed. in onCreateView() I have:

  if (view != null) {
      return view;
  }
  

  because I save the view of HVLV fragment in variable.

• everything looks ok, but when I try scrolling HVLV I get errors:

Error in fillListRight:Invalid index 21, size is 0
in:

    try { 
            viewRecycled = mRecycleBin.get( viewType ).poll();
    } catch (Exception e) {
            Log.e(LOG_TAG, "Error in fillListRight:" + e.getMessage());
    }
    View child = mAdapter.getView( mRightViewIndex, viewRecycled, this );

or

removeNonVisibleItems() error:Invalid index 24, size is 0

    try {

        child = getChildAt( getChildCount() - 1 );
        while ( child != null && child.getLeft() - positionX >= mRightEdge ) {

            if ( null != mAdapter ) {
                int position = getPositionForView( child );
                int viewType = mAdapter.getItemViewType( position );
                mRecycleBin.get( viewType ).offer( child );
            }

            removeViewInLayout( child );
            mRightViewIndex--;
            child = getChildAt( getChildCount() - 1 );
        }
    } catch (Exception e) {
        Log.e(LOG_TAG, "removeNonVisibleItems() error:" + e.getMessage());
    }

• there is something wrong with mRecycleBin

Btw the code works with this try and catch...

Hi,

I am using HorizontalListView as a header for a standard listView. It is working well however sometimes the HorizontalListView fails to respond to interaction. The only way to get the HorizontalListView to respond to touches is to scroll it out of view and then scroll it back into view.

Any idea what could be causing this?

Everything seems to work fine, but I get the following exception in the preview (Android 0.4.4)

What should I do to use HorizontalVariableListView with BaseAdapter. I have class:

public class BrochuresHorizontalAdapter extends BaseAdapter{
private SparseArray items;
...
}
which stores list items in SparseArray. Unfortunately sometimes removed views by recycler are not recreated. getView is not invoked on low positions and items simply disappear. (--update: getView() is invoked)

Is it because I need some special things to make it work as Listview?

maybe question doesn't have sense, because BaseAdapter implements ListAdapter. But what could cause such behavior.

Hi

I am using HorizontalListView in VerticalViewPager (https://github.com/castorflex/VerticalViewPager). I have multiple fragments in viewpager. When viewpager is created, fragment and horizontallistviews inside the fragment are created with no problems. But after scrolling to other fragments and come back to the fragment with horizontallistviews, horizontallistviews are removed from the screen. As i see, horizontallistviews are there but there is not cell, no items in it. I have also checked the adapter and item count. Nothing seems wrong. what might be the problem?

Thanks in advance.

It appears that all of the smoothScrollTo methods simply snap to the given item, even ones with explicit duration arguments. Is this a known bug?

This is using version provided by Maven
compile 'it.sephiroth.android.library.horizontallistview:library:+'

Please add "center lock" feature to simulate the deprecated Gallery.

Gradle fails with error: No such property: sonatypeUsername

Build fails when sonatypeUsername is undefined.

Proposed patch fix.
