Retrieve Group Members

Fetch and filter group members list using the Android SDK

AI Integration Quick Reference

// Fetch group members with filters
val groupMembersRequest = GroupMembersRequestBuilder("GUID")
    .setLimit(30)
    .setSearchKeyword("search")
    .setScopes(listOf("admin", "moderator"))
    .build()

groupMembersRequest.fetchNext(object : CallbackListener<List<GroupMember>>() {
    override fun onSuccess(members: List<GroupMember>) { }
    override fun onError(e: CometChatException) { }
})

Retrieve the List of Group Members

Use GroupMembersRequestBuilder with the group’s GUID to configure filters, then call fetchNext(). Each result is a GroupMember object.

Set Limit

Set the number of members to fetch per request.

Java

GroupMembersRequest groupMembersRequest = new GroupMembersRequest.GroupMembersRequestBuilder(GUID)
  .setLimit(limit)
  .build();

Kotlin

val groupMembersRequest = GroupMembersRequestBuilder(GUID)
  .setLimit(limit)
  .build()

Set Search Keyword

Filter members by a search string.

Java

GroupMembersRequest groupMembersRequest = new GroupMembersRequest.GroupMembersRequestBuilder(GUID)
  .setSearchKeyword("abc")
  .build();

Kotlin

val groupMembersRequest = GroupMembersRequestBuilder(GUID)
  .setSearchKeyword("abc")
  .build()

Set Scopes

Filter members by scope (e.g., "admin", "moderator", "participant").

Java

List<String> scopes = new ArrayList<>();
scopes.add("admin");
scopes.add("moderator");
GroupMembersRequest groupMembersRequest = new GroupMembersRequest.GroupMembersRequestBuilder(GUID)
  .setScopes(scopes)
  .build();

Kotlin

val scopes: MutableList<String> = ArrayList()
scopes.add("admin")
scopes.add("moderator")
val groupMembersRequest = GroupMembersRequestBuilder(GUID)
  .setScopes(scopes)
  .build()

Fetch Members

After configuring the builder, call build() then fetchNext() to retrieve members.

Java

private GroupMembersRequest groupMembersRequest = null;
private String GUID = "GUID";
private int limit = 30;

groupMembersRequest = new GroupMembersRequest.GroupMembersRequestBuilder(GUID).setLimit(limit).build();

groupMembersRequest.fetchNext(new CometChat.CallbackListener<List<GroupMember>>(){
  @Override
  public void onSuccess(List<GroupMember> list) {
    Log.d(TAG, "Group Member list fetched successfully: " + list.size());
  }
  @Override
  public void onError(CometChatException e) {
    Log.d(TAG, "Group Member list fetching failed with exception: " + e.getMessage());
  }
});  

Kotlin

var groupMembersRequest:GroupMembersRequest?=null
val GUID:String="GUID"
val limit:Int=30

groupMembersRequest=GroupMembersRequest.GroupMembersRequestBuilder(GUID).setLimit(limit).build()

groupMembersRequest?.fetchNext(object:CometChat.CallbackListener<List<GroupMember>>(){
  override fun onSuccess(p0: List<GroupMember>?){
    Log.d(TAG, "Group Member list fetched successfully: " + p0?.size)
  }
  override fun onError(p0: CometChatException?) {
    Log.d(TAG, "Group Member list fetching failed with exception: " + p0?.message)
  }
})
