I have gone through other questions as well, but couldn't figure out something. I want to create a User list using the Expandable RecyclerView. The way I want it to be
My RecyclerView part is all done. Now my question is how can I achieve this expandable RecyclerView part programmatically. And if I can do this using any library which one would be best to use.

This is not duplicate of How to create RecyclerView with multiple view type?
There are question on SO for different views for different row in same list but this is not the same.
This is a very simple question as I am a beginner to android development and OOP as well.
I have multiple(three) tabs in my android app and each tab has a list of items inside it (like in whatsapp).
I have successfully created a list(not listView) using recyclerView in one of the tabs. Now I want to create another list under the second tab but I have to use the previously used adapter. I don't know how to use onCreateViewHolder() to return multiple holders.
I tried if(object instanceOf class) inside getItemViewType() but I dont know how to access the object for comparison.
You can use the same adapter in all the three tabs. And for Recycler View you can use 3 different objects for those 3 tabs. This process might help in creating multiple Recycler Views.
I am learning android development and i am kinda stuck here. I want to create a friend list screen like shown in this picture.
What kind of activity should i use? Is there any available resources similar to what i want to achieve?
Thanks!
you can use ListActivity , also check out tutorials on lists, for example:
http://www.androidhive.info/2011/10/android-listview-tutorial/
http://www.vogella.com/tutorials/AndroidListView/article.html
you can find mire tutorials on google.
also you can use a regular Activity class with listView in the layout file
Use list view and custom adapter to populate the list view...
Listview should extend to the bottom but limit it just above the Type a name edit text and button.
Custom list view should contain linear layout horizontal in that include checkbox, Textview and Button
For type a name and Add use linear layout horizontal
Use listView with custom adapter , for array use arrayList<,friends,> sure you have to create friends class, in xml file put ListView then below that button and TextView
I am trying to implement treeView in android using listView. There is ExpandableListView but it has only 2 levels. I don't want any constrain on levels.
ListItem is custom view having textview & button.
Also for every level I want to show title.
How to make it possible in android? Do you have any clue?
Thanx in advance.
Please check thease options like
Treelist 1
Treelist 2
I want to create widget which will show some information divided into categories. I came with idea to use ExpandableListView in my widget. Is is possible? If yes - how to do this?
Yes, this is possible. you need to extend BaseExpandableListViewAdapter and implement the methods in it. You also need to make the layout xml files for whatever you want to show and specify this to the adapter or inflate it yourself if you have more than one.
A good example is http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList1.html which is where the expandable list is the whole activity on the screen but if you extend it like how i said in a seperate file and include a ExpandableListView in your activity that will work as well.
I have an app on the iPhone that is completely table view driven. On android all I see is a static table, how can I create a table that I can populate with data that I requested from the network.
You could use either ListView or GridView. ListView has a method getView which you override to customize ListView item. This very much like (UITableViewCell *)tableView... in iphone, except that you needn't count the height of each cell. If you want to have something like tableView with sections you could use ExpandableListView. Here are links to Android ListView, Android Expandable ListView and Android GridView. There can also be found very useful examples in Android Dev web-site.
You can use GridView or ListView with custom View for row. In both cases you can supply a BaseAdaper (or a subclass of it) through which you can manipulate the data.
If you want the exact grid border like example here you go Android Grid Border... Obviously you can render data dynamically from whatever the source is...
