Overview

Deprecated

This widget is now deprecated and it won't be updated anymore. Use RecyclerView instead

Horizontal Variable ListView

Horizontal ListView for Android. Based on the official ListView google code. The library includes also an ExpandableHListView, also based on the official ExpandableListView.
See the demo project for sample implementations

Usage (gradle)

Add this line to your dependency group:

compile 'it.sephiroth.android.library.horizontallistview:hlistview:1.2.2'

Features

It supports almost all the features of the ListView widget. There are minor differences in the attributes supported like "hlv_dividerWidth" instead of the default "dividerHeight".

This is the styleable used for the HListView class:

    <declare-styleable name="HListView">
        <attr name="android:entries" />
        <attr name="android:divider" />
        <attr name="hlv_dividerWidth" format="dimension" />
        <attr name="hlv_headerDividersEnabled" format="boolean" />
        <attr name="hlv_footerDividersEnabled" format="boolean" />
        <attr name="hlv_overScrollHeader" format="reference|color" />
        <attr name="hlv_overScrollFooter" format="reference|color" />
        
        <!-- 
        When "wrap_content" is used as value of the layout_height property.
        Pass the position, inside the adapter, of the view being used to measure the view
        or '-1' to use the default behavior ( default is -1 )
        -->
        <attr name="hlv_measureWithChild" format="integer" />
    </declare-styleable>
    

    <declare-styleable name="AbsHListView">
        <attr name="android:listSelector" />
        <attr name="android:smoothScrollbar" />
        <attr name="android:drawSelectorOnTop" />
        <attr name="android:cacheColorHint" />
        <attr name="android:scrollingCache" />
        <attr name="android:choiceMode" />
        
        <attr name="hlv_stackFromRight" format="boolean" />
        <attr name="hlv_transcriptMode">
            <enum name="disabled" value="0"/>
            <enum name="normal" value="1" />
            <enum name="alwaysScroll" value="2" />
        </attr>
        
    </declare-styleable>

2 days lost trying to understand why item click doesn't work

=(( 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.

OnItemClicked doesn't fire

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

The element view:

Would appreciate any help with this.

ClassCastException occurs when App Package is different than the R.java package

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.

Disapearing items, when scrolling HVLV

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.

Removed last Resources#getIdentifier calls.

Replaced the last Resources#getIdentifier calls with ordinary uses of R. This also fixes crashes due to missing resources when the APK package is renamed with aapt's --rename-manifest-package option.

Maybe simplify this a bit?
There was a request for a jar file to download earlier. The solution for that issue is frankly unsatisfactory. I think making this code open source is fantastic. Except that to use it in one's Android application, one must:

Get and learn how to use gradle.

Solve the bugs related to compiling this using gradle (I didn't btw, took too much effort).

Strip out all your styles associated with this widget.

Finally compile it into a jar.

Wonder where the last 2 days of time went.

Again, this is a sorely needed widget and I'm grateful that you've taken the time to convert ListView source over to a horizontal one. But as it is now, this is completely unusable in my opinion. I hope this spurs you to make what I'm sure would be a few minor changes to make this useful to the wide range of folks who are coming across it and (undoubtedly not using it).

Thanks, Matt

Problems with Proguard

ClassCastException - Adding a Footer

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?

Item width not being handled accurately

Setting the width to the outer most parent of my item layout, let's say, a RelativeLayout, I set the width of it to a fixed value, but it seems like this value is getting ignored, the item width is decided by the size of the views inside this RelativeLayout including padding and margin. It makes me hard to control the width of the items, not a big problem itself but I'm facing same problem with my own AdapterView(check this http://stackoverflow.com/questions/29716609/custom-adapter-view-child-not-being-measured-correctly), so I post this issue here hoping you would have any idea on this.Thanks

Button ClickListener not working Fragment to Fragment

I have created the 2 fragments, fragment_contact.xml and fragment_contacts3.xml along with their activity classes, fragment_contact.xml (Contact.java) as the button to which I added a clicklistener to fragment_contacts3.xml (Contacts3.java).

lock(freeze) the scroll

We use function disableScroll in early version, but in version 1.2.2, there is no disableScroll. Now we use setEnabled(false) but it still can be scrolled a little(not totally freeze) Please teach us how we can solve it? Thank you very much!

FloatMath.sqrt has been removed from Android SDK 23

The deprecated class has been removed.

"Historically these methods were faster than the equivalent double-based Math methods. On versions of Android with a JIT they became slower and have since been re-implemented to wrap calls to Math. Math should be used in preference. All methods were removed from the public API in version 23."

http://developer.android.com/reference/android/util/FloatMath.html

The library now needs to use eg. (float) Math.sqrt(pvxpvx + pvypvy);
