hi i created an app. In that when i hit a button it moves over to a new page, the page contains a list of item. The layout has been fixed as if a list view with a scroll view. Once i scroll the page is been changed over to a black screen. Is is this the problem in my coding or it is common to all apps
Add below line to your ListView in xml

I am a beginner, and i tried to find an answer but everything i found was from 2013 and earlier. I want to create a grid which you can scroll in any direction, (as a zoomed in picture), which contains items of different sizes which are generated randomly, then i want to populate them with a recycler view. I will attach an illustration, maybe you would understand it better.As you can see, the thick outline is the phone screen and whenever you scroll the view, it generates new items which are populated by a recycler view.
I thought of using Google's FlexBox Layout for generating the items but i don't really know how to create that scrollable view. I would literally pay to get this done.
I don't think you can make RecyclerView scroll in Both way. U can Create Nested RecyclerView if that is what you are looking for.
Text view changes as user scroll the screen
How can i achieve something like that as shown in gif file above link...
I have nested scroll view in activity and layout frame inside it, in which fragment is added..
That fragment contains multi recycler views and their title layout...I was unable to achieve this..please help
This effect called "Sticky Header" and you can achieve it without using third party libs.
Here is tutorial and direct link to code
I'm trying to change the tab as we scroll through the recycler view.
I have listed the items in single recycler view.
So when i reach the header ( for example Breakfast then Breakfast tab should be active ) of each section how to change tab accordingly?
The above gif explains my query. Please suggest me a solution.
I'm creating an app, that loads 2 xmls in listView (second one is loading when first scrolled down to the bottom).
So I want to show loading bar when 2nd xml is loading and parsing inside listView like on the second pic;
Is this even possible? :)
Because I have to put it on the layout and move my listView (thats not looking good).
Thanks
For first time loading you want progress bar to be loaded in screen center. so you make in your layout two element. one listview that covers whole screen and after that put progressview ... put them in master layout as Relative, so they will automatically adjust like listeview will be behind and progressview will be on top of it. in activity code set progressview visible on your server request. after first load when items are all loaded in adapter, hide progressview ...
for on scroll and infinite scrolling/loading here is a decent library that does that easily https://github.com/pwittchen/InfiniteScroll
I have a TabHost with a ListView inside a tab. When the activity starts, I can't scroll the list view until I have clicked off the tab that the activity starts on, and then re-select the tab with the list view inside it.
Note, I can get the list view to focus by calling:
tabHost.getTabContentView().requestFocus(); but unfortunately, I still can't scroll until I have reselected the tab...
Have any remedies?
Thanks!
Fixed - I ditched the tabs in order to simplify the layout.
