amrdeveloper / treeview Goto Github PK

First of all congratulations to the dev for making this great easy to use TreeView library 👏.
Describe the solution you'd like
My feature request is about to get a set margin option in TreeNode by default for each child layout. As you did in example projects extended custom class with TreeNode, i also tried the same to set my custom margin method but it didn't work for me. So if you make a default margin option in TreeNode it will be easy for noob devs like me.

Describe the bug
Child nodes have incorrect depth if they tree is constructed from bottom up with more then 3 levels.
Sample tree:

graph TD
0_lvl_0-->0-0_lvl_1
0-0_lvl_1-->0-0-0_lvl_2
0-0_lvl_1-->0-0-1_lvl_2
0-0-0_lvl_2-->0-0-0-0_lvl_3
0-0-0_lvl_2-->0-0-0-1_lvl_3

Actual levels of nodes (ignore incorrect parent of 0-0-0-0 and 0-0-0-1):

graph TD
0_lvl_0-->0-0_lvl_1
0-0_lvl_1-->0-0-0_lvl_2
0-0_lvl_1-->0-0-1_lvl_2
0-0_lvl_1-->0-0-0-0_lvl_2
0-0_lvl_1-->0-0-0-1_lvl_2

Problem is caused by the fact that node level update is done only for first level of children when node is added as child to another node, but it should be done recursively.

Easy solution would be to update child levels whenever node level is changed via setLevel.

To Reproduce
Steps to reproduce the behavior:

1. Create 4 level treenode hierarchy.
2. Check node level of 4th level leaf node.
3. Reported level should be 3 but will be 2.

Expected behavior
When adding node as child all it's children should have level updated recursively.
Also when setting node level via setLevel all it's children level should be recursively updated.

Please add more release for Android treeview.Recently I added your library in my Android apps.But can't implement treeview.So add more release in GitHub

First of all thank you for hard word this is a great component.
My question is how to prevent collapse action?.
I want to keep the ui unfolding

Describe the bug
Node can't be selected again if it was selected and then unselected.
Issue appears to be here

if (currentNode == currentSelectedNode) {
  currentSelectedNode.setSelected(!currentSelectedNode.isSelected());
} else {
  if (currentSelectedNode != null) currentSelectedNode.setSelected(false);
  currentSelectedNode = currentNode;
}

To Reproduce
Steps to reproduce the behavior:

1. Create tree with at least one node
2. Click on the same node 3 times
3. The node state is unselected

Expected behavior
If user is clicking on the same node it's state should switch between selected/unselected

Additional context
Workaround for this issue is to click on different node, thus breaking the loop which is keeping the node in unset state.

Hi,
I'm a beginner in java and I would like to use this library but I don't understand how to use it. The example is half explained, for example I don't understand what are the parent and child layouts.
If you have just a working example it would help me a lot!
Thanks

How do I get all the storage folders and add them to the treeViewAdapter? I've tried all sorts of ways, but I can't.

File root = new File("/storage/emulated/0/");
for (File file : root.listFiles()) {
    TreeNode node = new TreeNode(file.getName(), R.layout.layout);
}

The problem is adding the child folders, I don't know how to do this.

Describe the bug
When the tree is shown for the first time, it is all expanded but the treeNode class has a false set in isExpanded variable, because of this when you tap on the node it expands again replicating it's childrens.

To Reproduce
Steps to reproduce the behavior:

1. Just create a Tree with atleast 3 child'
2. Expand the First Node
3. you will see duplicate child node

Expected behavior
Either the tree should be collapsed from the start or isExpanded should be set to true.

The application is the treeview checkbox. How to uncheck the treeview settings so that the treeview objects are also unchecked?

Hi! First of all thank you for open source such a useful component. In the process of using it, I added the checkbox myself, and wanted to support the check function, but because of my limited level, there were many problems in the process of customization. Will the multi-select function be added in the future?
