   I found a solution

   1. you create a class like that

   public class UtilityHolder {

   public static void collapseOthers(TreeNode mNode, AndroidTreeView treeView){
       if(mNode.isExpanded()) {
           TreeNode parent = mNode.getParent();
           for (TreeNode node: parent.getChildren()) {
               if(node != mNode){
                   treeView.collapseNode(node);
                   collapseChildern(node,treeView);
               }
   
           }
       }
   }
   
   private static void collapseChildern(TreeNode mNode, AndroidTreeView treeView) {
       if (!mNode.getChildren().isEmpty()) {
           for (TreeNode node : mNode.getChildren()) {
               treeView.collapseNode(node);
               collapseChildern(node,treeView);
           }
       }
   }
   

   }

   2. you call the method collapseChildern in your Holder

   @OverRide
   public void toggle(boolean active) {
   UtilityHolder.collapseOthers(mNode,treeView);
   }
