I want to make two seperate grids, one with 2 columns and 8 rows and another with 4 columns and 8 rows. Which layout should I choose? It only needs to work vertically and there should be some space on the top for a button. I don't want any elements to disappear, but I would also prefer not to scroll to see all elements.
You can use a GridLayoutManager instead of a LinearLayoutManager when you set the RecyclerView up.
recyclerView.setLayoutManager(new GridLayoutManager(this, numberOfColumns));
Also, this tutorial will provide you further detail https://www.android-examples.com/android-recyclerview-with-gridview-gridlayoutmanager/.
I want to make the width of a recyclerView wider than the width of the layout itself so that only a part of the items of the recyclerView could be seen until the user scroll to the left.
I think an image can explain it better:
Each item of the recyclerView have 5 textViews like this:
And I want to see only 4 of them until the user scrolls to the left like this:
After scrolling, the first textView shouldn't be seen until the user scrolls to the right.
How can I accomplish that? Should I change the item layout to be larger than the screen or the recyclerView?
You must be looking for something like this.
Embed the RecyclerView (nestedScrollingEnabled=false) inside a Horizontal Scrollview
List item for Recyclerview should have the width set to wrap_content

I am new android studio developer.
I am using listView , so I want to limit the items previewed for each screen, for example I want only 6 items only to be shown on screen.
I couldn't find any xml attribute can help.
For you list adapter only add 6 items to it or return 6 for the count of items in the adapter. Just because you pass in a full array you don't have to display every item in the array.
There is a general move away from ListView / ListAdapter to RecyclerView / RecyclerViewAdapter so you many want to consider moving to them as well.
I want to use expandable listview as a main part of a fragment of my app.What I want to achieve is when I click a item of the expandable listview,the item would show something else like a image.However,it gets fine when I click the the 7th,8th,or lager than 8 item of the listview,but the image will not show if I click the top 6 item of the expandable listview. I think it would be something of expandable listview's cache,but I don't know how to fix it.
In android can i put animations to each rows (view) of a List. What I want o achieve that rows at even position should translate from left of screen and rows at odd positions should translate from right.
put the animations(using startAnimation) to each view of row in getView method of Adapter.
