List operators in open channel

An operator list is a complete list of operators of an open channel. The operator list is created through OpenChannelOperatorListActivity or OpenChannelOperatorListFragment.

An operator list screen is composed of three components: header, operator list, and operator list status.

To view the image in full screen, click on the

The header component shows the default title of the operator list screen as Operators. It also has a button on the right corner of the header. When tapped, the finish() method of the activity is called to exit the screen. The view of the header is created and customized in the HeaderComponent of the OpenChannelOperatorListModule.

The operator list component shows a list of profile images and names of the channel operators. The view of the operator list in an open channel is created and customized in the OpenChannelOperatorListComponent of the OpenChannelOperatorListModule. You can also customize each item in the list view using OpenChannelOperatorListAdapter.

The operator list status component shows the result of the data request for an operator list. The StatusComponent exists in the OpenChannelOperatorListModule and lets the user know if the list is loading or if the list could not be called.

UIKit for Android provides both activity and fragment to create an operator list screen. You can choose which one to build your app with and you may solely use activity instead of fragment if you wish to. You can build an operator list screen through OpenChannelOperatorListActivity, which uses UIKitFragmentFactory to create views.

You can start an activity by using intent to move from one activity to OpenChannelOperatorListActivity as shown below:

val intent = OpenChannelOperatorListActivity.newIntent(context, "channel_url")
startActivity(intent)

OpenChannelOperatorListActivity allows you to create a basic OpenChannelOperatorListFragment through UIKitFragmentFactory and OpenChannelOperatorListFragment.Builder. UIKitFragmentFactory has a set of methods that build each fragment, whereas the builder class provides APIs to customize the UI of the data and event handlers used in OpenChannelOperatorListFragment. To see all APIs of OpenChannelOperatorListFragment.Builder, refer to the API reference page.

val fragment = OpenChannelOperatorListFragment.Builder("channel_url").build()

Note: To use UIKit's fragments as a nested fragment, refer to the Android Developer Documentation's Nested Fragments.

In the list operators in open channel key function, you can customize OpenChannelOperatorListFragment to change different parts of the screen. The OpenChannelOperatorListFragment.Builder class allows you to create and customize the basic OpenChannelOperatorListFragment that UIKit provides but you can only change its own APIs, such as setting a layout. If you wish to customize the fragment beyond using the APIs provided in the builder, you must inherit new customization methods.

The following table shows the main classes used in OpenChannelOperatorListFragment to display and customize the operator list screen.

Depending on the UI or the feature you wish to customize in the fragment, you can change the classes mentioned in the table. To learn how to customize the fragment, see the Customization overview page for further details.

Note: The links to the above customization pages provide an example of how to customize classes related to ChannelFragment. In order to make changes to the operator list, you must use the correct classes.
