Add maxline attribute support

[Letty-Liang]

hope to be added in order to limit the maxLines

[thagikura]

Thanks for the suggestion, but I don't come up with an use case where the maxLines attribute is useful. Like what use case do you expect that attribute?

First issue I had when I tried FlexBoxLayout. It would be helpful if we had this attribute. In my case I have a FlexBoxLayout on top of a RecyclerView. The FlexBoxLayout shows the names of the selected elements in the list. In my case I don't want it to be more than two lines (otherwise the FlexBox would cover the screen if I select many elements), I would show a label "+N" for the rest of the selected items.

what about this functionality?

So, no progress with this?

[YuriDenison]

It would be useful in my case too.
Could you please provide any ETA for this issue?

Same problem, i only need one line in header of RecyclerView

I wanted to be careful for adding a feature that the original Flexbox doesn't have, but it looks like this is going to be useful for a lot of developers.
I'll add this feature on my TODO list.

Same problem, not only and
add enqueue child view to pop old child view also limit flexboxlayout max lines

[Coehill]

Also looking for this feature. I noticed that this issue is closed but it references another issue which is also closed and references this issue. Maybe you should leave this one open since it hasn't been implemented yet.

My use case is that I have is a list of items which could have only a few items or dozens. In the latter case, I don't want it to fill the entire screen and therefore need a limit to how many lines are shown.

manager.setMaxLine(1) is useless for FlexboxLayoutManager.

private static class OnViewGlobalLayoutListener implements ViewTreeObserver.OnGlobalLayoutListener {
    private final static int maxHeight = 130;
    private View view;

    public OnViewGlobalLayoutListener(View view) {
        this.view = view;
    }

    @Override
    public void onGlobalLayout() {
        if (view.getHeight() > maxHeight)
            view.getLayoutParams().height = maxHeight;
    }
}

add listener to RecyclerView:

view.getViewTreeObserver()
                  .addOnGlobalLayoutListener(new OnViewGlobalLayoutListener(view));

@thagikura It should be maxVisibleLines, not maxLines

How do I use maxLine whilst preserving item widths? I am essentially trying to achieve the above; add all items to wrap but only show the first line but setting maxLine squishes all items onto 1 line

Seems related to #440
