List channel members
A member list is a complete list of users that are members of a group channel. The channel member list is created through
Channel member list screen
A channel member list screen is composed of three components: header, member list, and member list status.
The header component shows the default title of the channel member list screen as
Members. It also has two buttons on the left and right corner of the header. When the left button is tapped, the
finish() method of the activity is called to exit the current screen. When the right button is tapped, the invite user screen is called where you can add new users to the channel. The view of the header is created and customized in the
HeaderComponent of the
The member list component shows a list of profile images and names of all members of the channel. For channel operators, the status
Operator is displayed next to the name. The view of the member list is created and customized in the
MemberListComponent of the
MemberListModule. You can also customize each item in the list view using
Member list status
The member list status component shows the result of the data request for a channel member list. The
StatusComponent exists in the
MemberListModule 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 channel member 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 channel member list screen through
MemberListActivity, which uses
UIKitFragmentFactory to create views.
Start an activity
You can start an activity by using
intent to move from one activity to
MemberListActivity as shown below:
Create a fragment
MemberListActivity allows you to create a basic
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
MemberListFragment. To see all APIs of
MemberListFragment.Builder, refer to the API reference page.
Note: To use UIKit's fragments as a nested fragment, refer to the Android Developer Documentation's Nested Fragments.
In the list channel members key function, you can customize
MemberListFragment to change different parts of the screen. The
MemberListFragment.Builder class allows you to create and customize the basic
MemberListFragment 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
MemberListFragment to display and customize the channel member 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, follow the links to Customization listed below:
- Customize the layout of the view
- Customize style of the view
- Bind event handlers to the view
- Add new APIs to the fragment
- Update or change an item in a list
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 channel member list, you must use the correct classes.
