Overview

FloatingGroupExpandableListView

FloatingGroupExpandableListView is a huge name an open source Android library that provides a floating group view (aka anchored / pinned / sticky section header) at the top of the ExpandableListView. This lib is based on Emil Sjölander's StickyListHeaders.

Sample Screenshot Sample Animation

Features

  • Works with list headers, footers, dividers and padding.
  • Works with partially transparent or hidden group views.
  • Handles touch events on the floating group view properly.
  • Allows group transition animation.

Sample Application

Get it on Google Play

The sample app project code is also included on this repository.

Usage

The FloatingGroupExpandableListView is very easy to setup. You just need a few steps:

  1. Add the FloatingGroupExpandableListView to your xml file. It will look something like this:

    <com.diegocarloslima.fgelv.lib.FloatingGroupExpandableListView
android:id="@+id/my_list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

  2. Then add these lines to your java code (usually on your Activity.onCreate() or Fragment.onCreateView() method):

    FloatingGroupExpandableListView myList = (FloatingGroupExpandableListView) findViewById(R.id.my_list);
BaseExpandableListAdapter myAdapter = new MyAdapter();
WrapperExpandableListAdapter wrapperAdapter = new WrapperExpandableListAdapter(myAdapter);
myList.setAdapter(wrapperAdapter);

  3. That's it! You're ready to go! For a complete implementation, you can take a look at the sample project.

Gradle

Add the following dependency to your build.gradle file:

dependencies {
    compile 'com.diegocarloslima:fgelv:0.1.+@aar'
}

  • 1st Group not clickable/expandable

    1st Group not clickable/expandable

    Hi, I just discovered your library and I must say it is amazing! One bug I found (except for the reflection errors in older API versions other people have mentioned) is that the first group header in my list does not expand when clicked (all other groups work well and as expected). I have tried debugging the matter and it should not be happening, since the click is not dispatched to the floating group (as it shouldn't be) and it is passed to super.discpatchTouchEvent(). It seems that the floating header is actually picking up the click somehow, though. Maybe it has something to do with my headers layout (they are simple horizontal linear layouts with android:clickable=false, having a textview and a button with a click handler as children). Any suggestions would be appreciated...

  • NullPointerException in view measure

    NullPointerException in view measure

    Hi, My app is crashing on scrolling the list in emulator and some Sony Ericsson devices. I found that the crash started coming after this commit https://github.com/diegocarloslima/FloatingGroupExpandableListView/commit/1e3f7b0c9400d110a8c6df047ceb2ffcc7ef80d1 According to the error logs, the crash is because of a NullPointerException in RelativeLayout.onMeasure - which is called by mFloatingGroupView.measure(childWidthSpec, childHeightSpec);

    IllegalStateException because FloatingGroupExpandableListView was never registered

    This library is fantastic, but there is one issue that is keeping me from using it. For some reason, if I navigate away from a fragment that uses a FloatingGroupExpandableListView, I get an IllegalStateException because the library tries to call unregisterDataSetObserver, despite my not using an observer, and never having registered the view.

  • How to get fixed headers irrespective of the child view container height

    How to get fixed headers irrespective of the child view container height

    First thank you for this awesome library :)

    I am using three group headers... everything runs fine as long as the middle group header have limited number in number of items. However when the number of items within the second header is large, the other headers are pushed out of the viewing container although we can still scroll and go to that header but, that is not the desired behaviour I was looking for.

    Is there a way I can make all the headers stick to their place?

  • Item selection is lost after group expand/collapse

    Item selection is lost after group expand/collapse

    Hi! :-) We can initialize the FloatingGroupExpandableListView with the listSelector to have list items highlighted on item click. However, that selection is lost after any group (even the group that doesn't hold the tapped item) expand/collapse.

    I believe that the item selection should not be lost at group expanding/collapsing because expand/collapse is just a way of data visualization, while the data is the same (e.g. with one selected item).

    What do you think about it? Thanks

  • Pinned group view has changed height

    Pinned group view has changed height

    Hi Diego, At the moment group view may have different heights based on the state: pinned or not. Imagine that we have group views with fixed height of 100dp (I've added a grey background to visualize group view bounds): http://i.imgur.com/C2xEige.png - looks fine.

    However, when the group view becomes pinned it will look like that: http://i.imgur.com/ewyK4aB.png - as you can see group view height was changed!

    Steps to reproduce

    1. take the stock FloatingGroupExpandableListView sample
    2. at sample_activity_list_group_item.xml change root layout height from android:layout_height="wrap_content" to android:layout_height="100dp". So we want to have fixed height to groups which is perfectly normal.
    3. at SampleAdapter.java change next line at getGroupView method from: v = mLayoutInflater.inflate(R.layout.sample_activity_list_group_item, null); to v = mLayoutInflater.inflate(R.layout.sample_activity_list_group_item, parent, false);

    Reason the real reason is how you inflate the group view at step 3. When we call mLayoutInflater.inflate without parent param inflater will ignores original layout params of the group layout (so we loose 100dp height). And seems the same you do when pin the group view, so it ignores initial view size and measure it as min height + paddings. Which is not fine. Group view should looks the same pinned and unpinned.

    You may want to read a good explanation of the proper layout inflater usage at: http://www.doubleencore.com/2013/05/layout-inflation-as-intended/

    Thanks

  • How to add an OnChildClickListener?

    How to add an OnChildClickListener?

    Dear Diego,

    great piece of software you have there. It almost worked out of the box for me. The only problem is that the OnChildClickListener which I had implemented in the same fragment where I also set up your FloatingGroupExpandableListView does not get called anymore, as it was the case before I used your extension. How would I implement such a listener while using your lib? Thanks for your answer!

    Cordially, CK

    Hi @diegocarloslima,

    Thanks for sharing this. I'm facing the following issue while implementing my custom child view xml .

    My problem is i clicked the button which is in Group 1's first child ie (G1 - C0) but it also reflects in all groups first child. How can i solve this. please reply back asap. Thanks in advance
