Create new channels in Sendbird UIKit using the
CreateChannelActivity. In the create group channel screen, the current user can select users from the user list to create a new group channel.
A create group channel screen is composed of three components: header, user list, and user list status.
The header component shows the default title of the create group channel screen as
New channel. 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 group channel screen appears where the curren user is in a new channel with the selected users. The view of the header is created and customized in the
SelectUserHeaderComponent of the
The user list component shows a list of users' profile images, names, and selectable checkboxes. By default, all users registered to the Sendbird application are retrieved in reverse chronological order of creation. The view of the user list is created and customized in the
CreateChannelUserListComponent of the
CreateChannelModule. You can also customize each item in the list view using
The user list status component shows the result of the data request for a message list. The
StatusComponent exists in the
CreateChannelModule 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 build a create group channel screen. You can choose which one to create your app with and you may solely use activity instead of fragment if you wish to. You can build a create group channel screen through
CreateChannelActivity, which uses
UIKitFragmentFactory to create views.
You can start an activity by using
intent to move from one activity to
CreateChannelActivity as shown below:
CreateChannelActivity 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
CreateChannelFragment. To see all APIs of
CreateChannelFragment.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 create channel key function, you can customize
CreateChannelFragment to change different aspects of the screen. The
CreateChannelFragment.Builder class allows you to create and customize the basic
CreateChannelFragment 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
CreateChannelFragment to display and customize the create group channel 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 create group channel screen, you must use the correct classes.
