List banned users in group channel

A banned user list in a group channel is a complete list of users that are banned from the channel. Only an operator of the channel can ban users. The banned user list is created through BannedUserListActivity or BannedUserListFragment.

A banned user list screen is composed of three components: header, banned user list, and banned user list status.

To view the image in full screen, click on the

The header component shows the default title of the banned user list screen as Banned users. It also has a button on the left corner of the header. When the left button is tapped, the finish() method of the activity is called to exit the current screen. The view of the header is created and customized in the HeaderComponent of the BannedUserListModule.

The banned user list component shows a list of profile images and names of all banned users from the channel. The view of the banned user list in a group channel is created and customized in the BannedUserListComponent of the BannedUserListModule. You can also customize each item in the list view using BannedUserListAdapter.

The banned user list status component shows the result of the data request for a banned user list. The StatusComponent exists in the BannedUserListModule 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 a banned user 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 a banned user list screen through BannedUserListActivity, which uses UIKitFragmentFactory to create views.

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

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

BannedUserListActivity allows you to create a basic BannedUserListFragment through UIKitFragmentFactory and BannedUserListFragment.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 BannedUserListFragment. To see all APIs of BannedUserListFragment.Builder, refer to the API reference page.

val fragment = BannedUserListFragment.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 banned users in group channel key function, you can customize BannedUserListFragment to change different parts of the screen. The BannedUserListFragment.Builder class allows you to create and customize the basic BannedUserListFragment 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 BannedUserListFragment to display and customize the banned user 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 banned user list, you must use the correct classes.
