I'm trying to design a table UI for my activity. I would like three columns and a fixed number of rows (so that the view fill all allotted space). Each of the cells should be clickable, and able to host standard widgets such as textview of buttons. I also want to control the scrolling (virtual grid with infinite up/down data). Pretty much something like the image below.
What is the recommended way of making a UI like this?
ListView?
TableLayout with dynamically added rows?
Custom class derived from View?
OpenGL?
I tried both 1 & 2, but so far have not been happy (hard to control height of each row). Any comments and code samples welcome.
Your app looks like it works with DB. If so TableLayout is not good to work with things like content providers/ loaders/ CursorAdapter…
Custom view is up to you but I think, based on the image, ListView is good enough. And let it manage the row height itself, that's not a big deal.
I'm not sure about OpenGL. For simple thing, I'd choose ListView/ GridView.

I'm trying to make a dashboard like app to display real time data to a user in a vehicle with a layout similar to the included screenshot. I've tried googling for a direction to follow to try and mimic google's responsive grid columns design principle. However, I can't find any examples of that principle in practice on android. How would I go about implementing this type of design in android? Would you use Grid Layouts?
Ideally I'd like to be able to have a Grid Layout that has cells that are consistent in size that allow me to span a Card View across columns and rows but I don't know of a way to do this using a Grid layout. Any ideas?

Take a look at GridLayout. It will allow you to define a grid and to span columns/rows. I was also going to mention GridView, but I don't think that it allows spanning of cells.
Another possibility is FleboxLayout if you need more flexibility. TableLayout also permits spanning.
You can also build a grid layout directly with ConstraintLayout using the "GuideLine" object.
Those are four layouts that I would consider.

Similar to the above app, I am trying to create a scrolling list of images, like a Listview but with images only. (I also need to set it to fill a set height and width, say 85% of the height, 10% of the width of the screen). Is a one column Griview best? (I have had troubles in the past selecting the image height of a gridview programatically).
Any online tutorials precisely for this you have used?
If your view is going to have only one element per row, then the best and correct way of implementation is to use a ListView. The GridView should or can be used when there are going to be multiple elements per row. I believe the purpose of ListView satisfies its role for your need.
For creating a GridView with uneven rows similar to how Pinterest looks. Includes own OnItemClickListener and OnItemLongClickListener, selector, and fixed position restore. Check out this link, there is a library named "StaggeredGridView" : https://github.com/maurycyw/StaggeredGridViewDemo
As there is no text and only one column of buttons, it seems like I overlooked the obvious answer of using a scrollview of buttons, which is what I will go with. Thanks for your assistance.
I would like to create a grid of dots very much like in this game: https://play.google.com/store/apps/details?id=com.nerdyoctopus.gamedots&hl=en
The aim is for each dot to be touchable, so I can recognise where that particular dot is and other information about it.
I don't really know where to start. Do I want to create a custom View for a dot with all the information I want, and then create multiple versions of it? And then do I arrange them in a grid with the setTranslation() method, or would it be better to use LayoutParams with offsets?
If I created my own "Dot" that extended "View", then I could add a lot of different information/methods to it - I could theoretically have a changeColor() method. Is this the best way?
A GridView is not what I am thinking of (as far as I know) as it is basically a different style of ListView.
There are lots of questions here! I have looked at a number of questions here on StackOverflow and elsewhere, but none show/ explain how I should start.
I would use a TableLayout for this. A GridView is the equivalent of a ListView in a 'grid' form, with scrolling, view recycling and whatnot, and that is not what you need. A GridLayout, as Dalmas suggested, would be a much better option if you want to build a static grid, but in my experience it is not easy to distribute the available space equally between columns, and if you are going to need to alter the grid distribution during the game, a TableLayout is much easier to use.
For the dots, yes, a custom view with a configurable color would be the best way to go around it.
You should use a GridLayout. It will do exactly what you need. It is available through the android support library v7 : http://developer.android.com/tools/support-library/features.html#v7-gridlayout
It allows you to arrange views using a grid of rectangular cells.
For the dots, I would go with a custom dot view as you suggest, with a simple method to set the color. Don't store any data in the views if possible, it will make things much easier and flexible.
I am developing an app and am looking for some general guidance:
The app is a memory trainer, and will have a couple of different modes:
Numbers: Up to 400 digits will be displayed on the screen in a gridlike pattern
Faces: Images of faces will appear, approximately 9 to a page, also in a grid pattern
The question is: can I accomplish this with a single xml layout file, and should I use the same layout type for each (and if so, what should it be!) ? It's a large app, so consistency would be heavenly.
I would prefer a layout with flexibility, and I am leaning toward GridView right now.
Any thoughts?
A Grid view is basically like a list view where items are arranged in a static grid.
It retrieves views from the Adapters as scrolled by user.
A table layout is a layout manager and does not do scrolling if required.this means u have to put it inside a scroll view. This implies that all of the data you are displaying must be populated into the TableLayout up-front, so the ScrollView knows the total space it is to scroll in. It also does not directly give you per-"item" selection or interaction, because a TableLayout doesn't have items, it is just a layout manager.
Also Adapter -based view should be used where significant amount of data is there to be scrolled. So it seems that grid view would be more suitable in the situation u r working.
How do i create this kind of views in my application?
(The screenshot is actually of an android application available in android market).
I am confused as i assume that we can create the same kind of layout either by using Gridview or by using ListView.
Problems:
In Gridview, can we give separator between two rows? can we give background to each row in gridview?
In Listview, i think we can customize the listview with 3 books in a row with background, and we can give a separator as well.
From your expert side, please suggest me a possible solution to design and create the same kind of layouts for the android application.
Look at the code of Shelves, written by Romain Guy (one of the ListView's creator).
He used a GridView:
no separator
background is a bitmap drawable
< bitmap
xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/shelf_panel"
android:tileMode="repeat" />
background image is like this:
The code is worth a look because it contains other interesting solutions, too.
Stated problems:
In Gridview, can we give separator between two rows? can we give background to each row in gridview?
Well, you can always make up a separator by adding something on the bottom of your view. Make it so that it 'connects' on the sides, and you won't know the difference. It will cost you an extra view per grid-item, so probably not the best option.
In Listview, i think we can customize the listview with 3 books in a row with background, and we can give a separator as well.
Eeuhm, yes, although I don't see what the problem is?
With a ListView, each row is counted as an element, so there will be extra work in logic that keeps each item within the row separate. I would suggest you use a gridview. For each grid element, keep an empty shelf space (for one book) as the background image. This image will include the shelf-base. So there is no need for additional rows. The image should look like this:
I would instead suggest to have grid view and view flipper if the number of books are limited.
View flipper will give a better effect than scrolling.
