List operators in open channel
An operator list is a complete list of operators of an open channel. The operator list is created through
Operator list screen
An operator list screen is composed of three components: header, operator list, and operator list status.
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
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
Operator list status
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.
Start an activity
You can start an activity by using
intent to move from one activity to
OpenChannelOperatorListActivity as shown below:
Create a fragment
OpenChannelOperatorListActivity 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
OpenChannelOperatorListFragment. To see all APIs of
OpenChannelOperatorListFragment.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 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, 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 operator list, you must use the correct classes.
