Before rotating, set the listViews width to the screen height And set the listviews height to the screens width.. (That is if you want the listview to fill the screen) else set the listview to the whatever height and width you want before rotating it.
This example demonstrates about How can I make a horizontal ListView in Android. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main.
To scroll a Flutter ListView widget horizontally, set scrollDirection property of the ListView widget to Axis. horizontal. This arranges the items side by side horzontally.
You might want to create a list that scrolls horizontally rather than vertically. The ListView widget supports horizontal lists. Use the standard ListView constructor, passing in a horizontal scrollDirection , which overrides the default vertical direction.
After reading this post, I have implemented my own horizontal ListView. You can find it here: http://dev-smart.com/horizontal-listview/ Let me know if this helps.
Have you looked into using a HorizontalScrollView to wrap your list items? That will allow each of your list items to be horizontally scrollable (what you put in there is up to you, and can make them dynamic items similar to ListView). This will work well if you are only after a single row of items.
You know, it might be possible to use an existing ListView with some judicious overriding of dispatchDraw() (to rotate the Canvas by 90 degrees), onTouch() (to swap the X and Y of the MotionEvent coords) and maybe onMeasure() or whatever to fool it into thinking it's y by x rather than x by y...
I have no idea if this would actually work but it'd be fun to find out. :)
This might be a very late reply but it is working for us. We are using the same gallery provided by Android, just that, we have adjusted the left margin such a way that the screens left end is considered as Gallery's center. That really worked well for us.
I used Pauls (see his answer) Implementation of HorizontalListview and it works, thank you so much for sharing!
I slightly changed his HorizontalListView-Class (btw. Paul there is a typo in your classname, your classname is "HorizontialListView" instead of "HorizontalListView", the "i" is too much) to update child-views when selected.
UPDATE: My code that I posted here was wrong I suppose, as I ran into trouble with selection (i think it has to do with view recycling), I have to go back to the drawing board...
UPDATE 2: Ok Problem solved, I simply commented "removeNonVisibleItems(dx);" in "onLayout(..)", I guess this will hurt performance, but since I am using only very small Lists this is no Problem for me.
I basically used this tutorial here on developerlife and just replaced ListView with Pauls HorizontalListView, and made the changes to allow for "permanent" selection (a child that is clicked on changes its appearance, and when its clicked on again it changes it back).
I am a beginner, so probably many ugly things in the code, let me know if you need more details.
Gallery is the best solution, i have tried it. I was working on one mail app, in which mails in the inbox where displayed as listview, i wanted an horizontal view, i just converted listview to gallery and everything worked fine as i needed without any errors. For the scroll effect i enabled gesture listener for the gallery. I hope this answer may help u.
