Custom Seat Layout

This document mainly introduces how to customize the seat layout for SeatGridView.
Prerequisites
Before using SeatGridView, you need to integrate and log in to SeatGridView to ensure the subsequent features work properly.
Usage guide
Step 1: Adding SeatGridView to the View
You need to import the SeatGridView module first, then create a SeatGridView object and add it to your view.
iOS
Android
import UIKit
import RTCRoomEngine
import SeatGridView 
﻿
class CustomizeSeatLayoutController: UIViewController {
    private let seatGridView: SeatGridView = {   
      let view = SeatGridView()
      return view
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Add seatGridView to the view and set layout constraints
    }
}
import com.trtc.uikit.livekit.seatGridView.SeatGridView;
﻿
public class CustomizeSeatLayoutActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        SeatGridView seatGridView = new SeatGridView(this);
        addContentView(seatGridView,
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    }
}
Step 2: Preparing Seat Layout Parameters
When calling the setLayoutMode API, you need to fill in the key parameters layoutMode and layoutConfig. The following is a detailed introduction:
Parameter 1: layoutMode
ayoutMode is an enumeration of type SGLayoutMode.
Enumeration value types
Meaning
Additional Notes
focus
Centralized layout
(e.g., 1-3-3 layout, 1 element in the first row, 3 elements in the second and third rows)
Built-in layout styles
grid
Grid Layout
Built-in layout styles (this is the default style)
vertical
Vertical layout
Built-in layout styles
free
Free layout
Custom layout styles
Notes:
When using the built-in layout styles of seatGridView, there is no need to provide additional SGSeatViewLayoutConfig parameters. You only need to pass the SGLayoutMode parameter to setLayoutMode.
Parameter Two: layoutConfig
layoutConfig is a structure of type SGSeatViewLayoutConfig, consisting of the fields rowConfigs and rowSpacing.
Parameter Name
Field Description
Data Type
rowConfigs
Used to store the configuration of each row's seat layout.
An array of SGSeatViewLayoutRowConfig type
rowSpacing
Used to store the row spacing of the seat layout
Floating point number
SGSeatViewLayoutRowConfig  consists of four fields: count, seatSpacing, seatSize, and alignment.
Parameter Name
Field Description
Data Type
count
Number of seats per row
Integer
seatSpacing
Vertical spacing of seats in the same row
Floating point number
seatSize
Size of the seat
Size type
alignment
Arrangement of seats in the same row
SGSeatViewLayoutRowAlignment
SGSeatViewLayoutRowAlignment is an enumeration.
Enumeration value types
Meaning
spaceAround
Dispersed alignment, not against the container wall, with remaining space evenly distributed on both sides of each item
spaceBetween
Spaced alignment, with the leftmost and rightmost items against the left or right border, and equal spacing between items.
spaceEvenly
Average alignment, not against the container wall, with remaining space evenly distributed.
start
Left alignment
end
Right alignment
center
Center alignment
Step 3: Setting the Seat Layout
After preparing the parameters layoutMode and layoutConfig in Step 2, you can call the setLayoutMode API function to set the seat layout.
Built-In Layout
When using the built-in layout, you only need to pass the layoutMode parameter.
iOS
Android
// Centralized layout
self.seatGridView.setLayoutMode(layoutMode: .focus)
// Grid Layout
self.seatGridView.setLayoutMode(layoutMode: .grid)
// Vertical
self.seatGridView.setLayoutMode(layoutMode: .vertical)
// Centralized layout
seatGridView.setLayoutMode(VoiceRoomDefine.LayoutMode.FOCUS, null);
// Grid Layout
seatGridView.setLayoutMode(VoiceRoomDefine.LayoutMode.GRID, null);
// Vertical layout
seatGridView.setLayoutMode(VoiceRoomDefine.LayoutMode.VERTICAL, null);
Custom Layout
When using a custom layout, the value of layoutMode should be free and the corresponding seat layout configuration parameter layoutConfig needs to be passed.
For example, to customize a 2, 1, 2 layout, with each row arranged as spaceBetween, center, and spaceBetween:
iOS
Android
// Create seat configuration for each row
let firstRowConfig = SGSeatViewLayoutRowConfig(count: 2, 
    seatSpacing: 10.0, seatSize: CGSize(width: 50, height: 50), alignment: .spaceBetween)
let secondRowConfig = SGSeatViewLayoutRowConfig(count: 1,
    seatSpacing: 10.0, seatSize: CGSize(width: 72, height: 72), alignment: .center)
let thirdRowConfig = SGSeatViewLayoutRowConfig(count: 2, 
    seatSpacing: 10.0, seatSize: CGSize(width: 50, height: 50), alignment: .spaceBetween)
    
let rowConfigs: [SGSeatViewLayoutRowConfig] = [firstRowConfig, secondRowConfig, thirdRowConfig]
let layoutConfig = SGSeatViewLayoutConfig(rowConfigs: rowConfigs, rowSpacing: 20.0)
﻿
// Set layout mode
self.seatGridView.setLayoutMode(layoutMode: .free, layoutConfig: layoutConfig) 
// Create seat configuration for each row
VoiceRoomDefine.SeatViewLayoutRowConfig firstRowConfig = new VoiceRoomDefine.SeatViewLayoutRowConfig();
firstRowConfig.count = 2;
firstRowConfig.seatSpacing = 10;
firstRowConfig.seatSize = new VoiceRoomDefine.Size(50,50);
firstRowConfig.alignment = SPACE_BETWEEN;
﻿
VoiceRoomDefine.SeatViewLayoutRowConfig secondRowConfig = new VoiceRoomDefine.SeatViewLayoutRowConfig();
secondRowConfig.count = 1;
secondRowConfig.seatSpacing = 10;
secondRowConfig.seatSize = new VoiceRoomDefine.Size(72,72);
secondRowConfig.alignment = CENTER;
﻿
VoiceRoomDefine.SeatViewLayoutRowConfig thirdRowConfig = new VoiceRoomDefine.SeatViewLayoutRowConfig();
thirdRowConfig.count = 2;
thirdRowConfig.seatSpacing = 10;
thirdRowConfig.seatSize = new VoiceRoomDefine.Size(50,50);
thirdRowConfig.alignment = SPACE_BETWEEN;
﻿
List<VoiceRoomDefine.SeatViewLayoutRowConfig> rowConfigs = new ArrayList<>();
rowConfigs.add(firstRowConfig);
rowConfigs.add(secondRowConfig);
rowConfigs.add(thirdRowConfig);
VoiceRoomDefine.SeatViewLayoutConfig config = new VoiceRoomDefine.SeatViewLayoutConfig();
config.rowConfigs = rowConfigs;
config.rowSpacing = 20;
﻿
// Set layout mode
seatGridView.setLayoutMode(LayoutMode.FREE, config);
