parent.windowToken must not be null

[sembozdemir]

Hi,

I could not make it to show tooltip. It always crash by saying parent.windowToken must not be null

Stacktrace:

Code to show tooltip:

Tooltip.Builder(activity)
        .anchor(deliveryTypeView, 0, 0, false)
        .text(R.string.product_sla_preselected_info)
        .arrow(true)
        .overlay(true)
        .create()
        .show(deliveryTypeView, Tooltip.Gravity.TOP, true)

What is wrong with my implementation? Could you please help?

I found the same issue. I fixed it by putting it in a view.post() call.

I the workaroud of Kassim it works, seems that you set the tooltip too early on the lifecycle, when no all the views was loaded.

Be sure to use OnViewCreated on Fragment or use the work around @kassim told

[kassim]

mine was in a ViewHolder of RecyclerView, which would have items added in onViewCreated maybe the 'show' method itself should be using post?

can you explain it how can i do?

[kassim]

select any view in your layout, for example a TextView, has a post method you can call

textView.post(()-> { showTooltip()})

[Joze01]

I was having the issue inside a recycler view. this fixed it:

holder.itemView.post { holder.showTooltip() }
