How can I get item layout from adapter ?

[jemmycalak]

I was try with this script but nothing happen.

View v =adapter.getView(0, null, graphView);
TextView t = v.findViewById(R.id.t1);
t.setText("TEST");

You're using this library in the wrong way. GraphView works similar to how you would use the RecyclerView. Create the adapter with the viewholder pattern. In the viewholder you have your item view, where you get your child views from. If you look in the readme you find an example or look in the sample folder.

yes, I was do same like you say, my graph is showing,, but I want to custom the node by get item layout from adapter..

Can you show me the simple code to that case ? I was see the sample code but nothing

What do you mean by "custom the node"? If you just want to change your data, you have to change it in the node object inside the graph. Then just call adapter.notifyInvalidated() to update the view.

Setting the data to the views should only be done inside the adapters onBindViewHolder method.

custom node layout,, not data of node.

I want to change item layout with different way,, not on onBindView,,
Can I do that ?

You can change the item layout in the onCreateViewHolder method, like here:
https://github.com/Team-Blox/GraphView/blob/43dd72340ce08dba9f62cb0c5228a2d56206414c/sample/src/main/java/de/blox/graphview/sample/GraphActivity.java#L47

Create a layout xml for your item and inflate it in this method. For different layouts in one graph you have to implement the getItemViewType and check the view type in onCreateViewHoler.

Like I said earlier, GraphView can be used just like a RecyclerView. You can google your problem and adapt the solution to GraphView or ask on StackOverflow.

yes,, that is still in onCreateView method, I want to different way, outside OnCreateView. like this:

No, this is not possible.
