How can I use a TreeView in a MaterialDialog?

[adryx92]

Hello, I'm quite new to Android development. I'd like to insert an AndroidTreeView in a custom dialog. I'm using this nice lib to create dialogs with custom layouts.

My test code is:

TreeNode root = TreeNode.root();
TreeNode parent = new TreeNode("MyParentNode");
TreeNode child0 = new TreeNode("ChildNode0");
TreeNode child1 = new TreeNode("ChildNode1");
parent.addChildren(child0, child1);
root.addChild(parent);

AndroidTreeView tView = new AndroidTreeView(this, root);
//containerView.addView(tView.getView());


MaterialDialog dialog = new MaterialDialog.Builder(MainActivity.this)
.title("Menu")
.customView(R.layout.menu_view, true)
.build();

and the definition of my menu_view has nothing except an id. What can I do then? How do I set the custom view before adding it to the dialog?

Thanks

Finally solved this way:

...
AndroidTreeView tView = new AndroidTreeView(this, root);

LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.menu_view, null);
ViewGroup containerView = (ViewGroup) view.findViewById(R.id.container);

MaterialDialog dialog = new MaterialDialog.Builder(MainActivity.this)
     .title("Menu")
     .customView(containerView, true)
     .build();
dialog.show(); 

Thanks anyway.

Hello, I've got another issue. I'm trying to represent my TreeView as the TwoDScrollingArrowExpandFragment from your sample. I create my TreeNode like this, passing your two Objects:

TreeNode tn1 = new TreeNode(new IconTreeItemHolder.IconTreeItem(R.string.ic_folder, pm1.toString())).setViewHolder(new ArrowExpandSelectableHeaderHolder(this));

but I get a runtime exception. Here's my stacktrace:

I think there's some layout problem. Can you please help me?

[bmelnychuk]

Looks like this is dependency issue, I used PrintView (https://github.com/johnkil/Print) to display icons from font

[adryx92]

Never mind, I created my own custom layout.

@adryx92 please can you suggest me how you did this ?

[veersamrat]
