A multi-level collapsible/expandable indentable list view for Android

multilevelexpandableindentablelistview's Issues

already expanded list

Is there any way to show list already expanded when view gets loaded?
In the current implementation, list gets expanded on clicking.
mAdapter = new MyAdapter(getActivity(), new View.OnClickListener() { @Override public void onClick(View v) { int position = mRecyclerView.getChildPosition(v); mAdapter.toggleGroup(position); } }); mRecyclerView.setAdapter(mAdapter);

Collapse/Expand Issue

As you can see from the images below, when I select an unexpanded item from a list the list collapses other root items first before I can expand any children.

What I'm doing in my code is
1. creating a hashmap of all the comments with their id as the key.
2. Iterating the list of comments and finding the parent of each item
and adding the current item as a child to that parent.
3. Getting all the top level comments and adding them to the adapter.

 public void loadComments(Submission detailedPost){
    this.post = detailedPost;
    root = TreeNode.root();
    lookup = new HashMap<String,Comment>();
    CommentNode commentRootNode = post.getComments();
    Iterable<CommentNode> iterableComments = commentRootNode.walkTree(TraversalMethod.PRE_ORDER);

    createNodeLookupMap(iterableComments);
    allocateChildrenToParentNodes();
    addTopLevelNodesToRoot();


}

public void createNodeLookupMap(Iterable<CommentNode> iterableComments){
    for (CommentNode node : iterableComments) {
        lookup.put(node.getComment().getFullName(), new Comment(node));
    }
}


public void allocateChildrenToParentNodes() {
    for (Map.Entry<String, Comment> entry : lookup.entrySet()) {
        Comment proposedParent;
        String entryParentId = entry.getValue().getCommentNode().getComment().getParentId();

        if(!entryParentId.equals(post.getFullName())){
            proposedParent = lookup.get(entryParentId);
            if(proposedParent != null) {
                proposedParent.addChild(entry.getValue());
            }
        }
    }
}

public void addTopLevelNodesToRoot(){
    List<Comment> comments = new ArrayList<Comment>();

    for (Map.Entry<String, Comment> entry : lookup.entrySet()) {
        // Get all the top level nodes and add them to the final list
        CommentNode node = entry.getValue().getCommentNode();
        if (node.isTopLevel()){
            comments.add(entry.getValue());
        }
    }
    commentsAdapter.addAll(comments);
    commentsAdapter.notifyDataSetChanged();
}

Getting demo to run, why is it so difficult. Readme needs an update.

Steps:

1. Download gradle version required 2.1, using manual method as Android Studio is bad in that respect.
2. Change runProguard false to minifyEnabled false in sampleapp/build.gradle and multilevelexpindlistview/build.gradle
3. Library projects cannot set the ApplicationId, so have to remove that line from multilevelexpindlistview/build.gradle

Duplicate item after insert item

After I insert an item into the list a duplicate is popping up.
It's not necessarily the one I just inserted that is duplicated. It is usually further down the list.
Anyone else have this issue or have a fix?

is there a way to start with a collapsed listview and then expand on click?

by default you see all the expanded rows and I would like to change this behavior.

Sometime collapseGroup has bug

when i collapseGroup maybe the group of last child show ,and the group item gone .i'm sorry for my english.

Add a gradle dependency

One of the reasons the library is not seeing high usage is because it is hard to add to your project.

How about using jitpack:
