Expandable ListView is a expandable collapsible vertical listview structure used to show multiple category and sub category wise list structure. It is also known as two level vertical scrolling listview. It is differ from simple ListView because in simple ListView or FlatList we will only show single level items but in Expandable ListView we will show multiple level items.

Currently there is no pure component available in react native to create Expandable ListView but using the custom component designing functionality we can easily create our own custom Expandable ListView.

This class would be our main custom Expandable ListView class. The componentWillReceiveProps method is used to re-compute the data when a prop value is changed in react native. The shouldComponentUpdate function is used to increase the app performance by disabling all the items re-rendering each time when user clicks a data. It will make sure the selected items data is loaded only not the complete List. This function is used to show the selected item of Expandable List View.

Here we would enable the layout animation. In this method we first enable the layout animation and then update the layout with new items. We would call the custom component in ScrollView. Complete source code for App. I want to use this in a different way. I have used checkbox instead of text. Now issue is how to manage the checked values from the array? Can we retrieve the list of data in array from database eg. If can, how? As for the example it has been listed in the code. Hi Sir. I am wondering if it is possible for sure it is possible :D to do a multi-select on the embedded list, so the part that can be hidden the collapsable part.Within SAP Fiori, we distinguish between tree tables and trees.

Both usually allow the user to display and work with a hierarchical set of items. While tree tables are usually used for more complex data, trees are generally used for rather basic data. Trees are mostly used in the master list for a master-detail scenario using the flexible column layout and in popovers or dialogs.

In certain use cases, they can also be used in the dynamic page layout. In the case of tree tables and trees, items that contain additional items are called nodes, while items that do not contain any other items are called leaves. If available, a single topmost node is called a root node. Apart from the hierarchical structure of its nodes and leaves, a tree is quite similar to a list.

Check out the table overview to decide which SAP Fiori table is most suitable for your needs. The tree is like a list containing hierarchical data.

It acts as a container for items, with the possibility to expand and collapse nodes. When reducing the width, item texts wrap to ensure that the tree adapts to the new size. In addition, the tree changes the indentation per level dynamically when the user expands a node, based on number of levels currently showing. The title bar optional contains the title of the tree. In addition, an item counter and toolbar items can be placed on the title bar. The collection of hierarchical items occupies the main part of the tree.

Android ExpandableListView Examples

The title bar consists of a toolbar. The toolbar can contain a titlean item count, and other toolbar items such as actions or view settings, for example. If additional controls are needed, use a custom tree item. The custom tree item allows you to use any combination of controls inside the tree.

The height of the tree is defined by the number of items it contains. It does not have its own scroll container, but is scrolled together with the app. When the user scrolls, the title and the filter infobar can stick to the top of the surrounding layout container sap. Tree, property: sticky. Sticky title Selection Modes A tree can have one of the following selection modes sap. ListBase, property: mode :. None: Items cannot be selected sap.

Beware: Items can, nevertheless, use the sap. This should only be used when the click triggers a navigation to a corresponding item details page. Single select master: One item of the tree can be selected. To select an item, click anywhere on the item. Single select master does not add any visual indication to the tree and therefore cannot be differentiated from trees without selection if no item is selected. Therefore, always keep one item selected.

For single selection, this is the preferred mode. Single select left: One item of the tree can be selected.Select the activity template as Navigation Drawer Activity as shown below. This encloses our activity class in a DrawerLayout and adds a NavigationView inside it by default. In our xml editor we see the following design of the activity:.

In this application each of our menus while open a url in a WebView. Some menus can be expanded while others cannot. The same class can be used for both the header and child rows of the ExpandableListView in this tutorial. For the group headers, we use an ArrayList of MenuModels.

The child rows data is populated in a HashMap where the key is the header MenuModel and the values are the list of child MenuModels.

At Google IOGoogle introduced the RecyclerView widget - an entirely updated approach to showing a collection of data. RecyclerView was designed to be more flexible and extendable than its predecessor, ListView. While most of what RecyclerView offers is an improvement over the existing functionality of ListViewthere are a few notable features missing from the RecyclerView API. Adapter s for expanding and collapsing groups to bring back some of the former glory of ExpandableListView.

To understand this library is to understand RecyclerView. According to the docs:. In other words, the adapter is just the middleman: translating indexes from some backing data structure, to views to be passed along to a RecyclerView to be seen on screen. When you are showing a single dimensional list of objects, this translation is simple. The indexes of the objects in the backing data set directly correspond to the indexes of views displayed on screen. But when you want to display two dimensional data, like in case of an expandable list, this translation gets a bit more tricky.

When the indexes of the views are the same as those of the backing data set, there is only a single truth to maintain. But when those indexes become disparate, so does the source of truth, leaving you with two possible truths.

Me too. Above is music app showing a list of Genre s with corresponding Artist s. The numbers to the left of the phones represent the view indexes. As you can see both phones contain 9 row items. But if you look at row 6, you will see the data on each phone is different.

On the left, view index 6 equals the Genre object, Classic while on the right it equals the Artist object, Miles Davis. Enter the double source of truth problem. The view indexes truth numero uno are different from the backing data structure indexes truth numero dos. The RecyclerView. If you look at all the callbacks and methods on RecyclerView. So to make this whole thing work, all we need some way to translate the two dimensional data to a flattened, single dimensional data set for the adapter to use.

ExpandableList acts as a translator between the flat list position i. The only reason we even had to include it as a separate class in this library was because it has package local scope within the Android SDK.

See the full library and instructions for how to use it on Github. Software design and development requires collaborative efficiency—the ability to quickly solve problems together. When a team is remote, productivity can plummet. The What To understand this library is to understand RecyclerView.

When initially Android team introduced the RecyclerView widget, we had to implement a custom Adapter in several applications, again and again to provide the items for our views.

We didn't know how to add selection and to combine all the use cases in the same Adapter. Since I created this library, it has become easy to configure how views will be displayed in a list, and now, nobody wants to use a ListView anymore. The idea behind is to regroup multiple features in a unique library, without the need to customize and import several third libraries not compatible among them.

The FlexibleAdapter helps developers to simplify this process without worrying too much about the Adapter anymore. It's easy to extend, it has predefined logic for different situations and prevents common mistakes. This library is configurable and it guides the developers to create a better user experience and now, even more with the new features. Wiki pages have been completely reviewed to support all the coming features of version 5. Some simple features have been implemented, thanks to some Blogs see at the bottom of the pagemerged and methods have been improved for speed and scalability.

High performance updates and filter on big list. Auto mapping multi view types with Item interfaces.The FastAdapter is here to simplify creating adapters for RecyclerViews.

Don't worry about the adapter anymore. It's blazing fast, minimizing the code you need to write, and is easy to extend. The library is split up into core, commons, and extensions. The core functions are included in the following dependency.

Just create a class which extends the AbstractItem as shown below. Implement the methods, and your item is ready. By default the FastAdapter only provides basic functionality, which comes with the abstraction of items as Item and Model.

To enable selectionsor expandables the provided extensions need to be activated. For further details scroll down to the ExpandableItems under advanced usage section. Create a FooterAdapter. We need this to display a loading ProgressBar at the end of our list. Don't forget to pass it into FastAdapter.

The FastAdapter comes with support for expandable items. After adding the dependency set up the Expandable extension via:. Expandable items have to implement the IExpandable interface, and the sub items the ISubItem interface.

Textview click effect android

Fan thrust calculator allows better support. The sample app provides sample implementations of those. As of the way how SubItems and their state are handled it is highly recommended to use the identifier based StateManagement.

A simple item just needs to extend from the AbstractExpandableItem and provide the ViewHolder as type. This free, open source software was also made possible by a group of volunteers that put many hours of hard work into it.

Based on your multi select and expandable list example, I'm trying to combine those two - I think I did not change anything relevant. BUT as soon as I start deleting something, it get's messed up.

Afterwards, more problems occur expanding a header that still exists will show selected items for example, We are currently in the progress of finalising the API changes and a huge refactor for the FastAdapter.

As it is really important for us to make the library as easy to use, but also as powerful and flexible as possible, we want to hear your feedback. Please check it out, and give us suggestions, review the changes, and contribute and help to make v3 the best release ever. Hello, I'm using Realm as my local backend and I would like to use the FastAdapter to populate my many RecyclerViews, however macaraig scandal realm models are separated from the ui part in its own project and each of the objects could be used on several views, so to extend my models as in the RealmExample is not an option.

Also I would like to be able to sort my adapters, and group them providing a group header. I've reading the documentation and the examples and I'm a bit confused about what adapter to use and where, and how to add a "headeritem". The following is what I have made so far:. This code is working ok and although I'm not so sure about if I should use the GenericItemAdapter or another adapter, it is very straightforward.

But I'm stuck here, I don't know If I have to change the itemAdapter so it can use both types of items ContenderItem and SectionItemor I can just wrap the itemAdapter in another adapter A HeaderAdapterbut then I don't know how to link both so they group properly.
