List

Convert the List design to iOS/Android code.
If you need to display scrolling elements dynamically, you should check if they are lists or grids. Lists are vertical, and grids can be vertical or horizontal. In lists, only 1 cell can be in a column but for Grids, it can be more than 1 cell in a column. Here is an example of both of them:
Lists and Grids
This page is created for lists. 
If you need to display scrolling elements dynamically, you should check if they are lists or grids. You can find how to understand the difference here. If you have decided that you want to create lists, this is the right place to read.
An example of a list is below. In the image, the cell prototype repeats itself with different data inside. 
Lists are called different names in iOS and Android. They are explained below with the code and details.

TableView
Lists are called inTableView Swift language. With TableView, you can view a group that aligns all children in a single direction. InTableView, no matter how wide they are, the vertical list has only one child per row, and your list will only be the one-row height(Height of the tallest child + padding).
CellPrototypewraps a layout and will often be the container used in a layout for each item within a TableView. Let's check the generated code.
TableView is added to the page's View Controller file. 
ListPageViewController.swift 
import UIKit
​
class ListPageViewController: UIViewController {
​
//Connection from an Interface Builder to a UI component
@IBOutlet private weak var explorePostsTableView: UITableView!
​
	override func viewDidLoad() {
		super.viewDidLoad()
		setupViews()
	}
}
​
extension ListPageViewController {
	private func setupViews() {
	
		//TableView properties
		self.explorePostsTableView.rowHeight = UITableView.automaticDimension
		self.explorePostsTableView.estimatedRowHeight = 30
		self.explorePostsTableView.dataSource = self	
​
	}
	
}		
​
// MARK: - Table View DataSource
​
extension ListPageViewController: UITableViewDataSource {
	func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
		return 1
	}
​
	func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
		let cell = tableView.dequeueReusableCell(withIdentifier: "ExplorePostTableViewCell") as! ExplorePostTableViewCell
		return cell
	}
}
The Cell is added as a separate file. 
ExplorePostsTableViewCell.swift
​
import UIKit
import SnapKit
​
class ExplorePost: UITableViewCell {
	
	// MARK: - Properties
	@IBOutlet private weak var photoImageView2: UIImageView!
	@IBOutlet private weak var rosieDelLabel: UILabel!
	@IBOutlet private weak var likesLabel: UILabel!
	@IBOutlet private weak var heartLikedImageView: UIImageView!
​
	override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
		super.init(style: style, reuseIdentifier: reuseIdentifier)
		self.setupViews()
	}
​
	required init?(coder aDecoder: NSCoder) {
		super.init(coder: aDecoder)
	}
​
	func setupViews() {
		
		rosieDelLabel.text = NSLocalizedString("rosie.del", comment: "")
		rosieDelLabel.textColor = UIColor.porpoise
		rosieDelLabel.numberOfLines = 0
		rosieDelLabel.font = UIFont.textStyle2
		rosieDelLabel.textAlignment = .left
​
		likesLabel.text = NSLocalizedString(".likes2", comment: "")
		likesLabel.textColor = UIColor.anchor2
		likesLabel.numberOfLines = 0
		likesLabel.font = UIFont.textStyle6
		likesLabel.textAlignment = .right
​
	}
}
Android
RecyclerView-LinearLayoutManager
⚠️This feature is available in only Mac App. Web App support for Android is coming soon.
If you need to install the desktop app, click here.​
In Android lists are used with RecyclerViewandLinearLayout. The repetitive cells are CardView 
With LinearLayout, you can view a group that aligns all children in a single direction. InLinearLayout, no matter how wide they are, the vertical list has only one child per row, and your list will only be the one-row height(Height of the tallest child + padding).
Android RecyclerView and CardView
CardView wraps a layout and will often be the container used in a layout for each item within a RecyclerView. Let's check the generated code.
