Shadow behind AutoFitTextView

[axelfran]

Hi,

I need to add a shadow behind the textview. The shadow has a quite large radius, so that it with my current solution will be clipped in many instances as the bounding box isn't increased when I add the shadow.

If this was a normal TextView I could just add some padding to it to avoid the clipping, however when I do that now the text becomes smaller. I would like to avoid that.

Anyone have any thoughts on how I should add padding without making the text smaller?

Thanks in advance!

I thought this is already handled.

As a workaround, you might be able to put it inside a container view (FrameLayout, for example), and add the padding there, and set "clipChildren" to false on the it. Maybe it will work for now.

Thanks! I will give this a try:)

Did it help?

[axelfran]

No, unfortunately I haven't been able to make it work for my use case yet. As you can see the shadow still seems to be clipped on the top and bottom.

I will look deeper into this issue in the coming days, so will post an update then! :D

odd. thank you for trying to fix it.

Perhaps rolling your own layout class may help... a base example for understanding forces the layout to be square. Perhaps you can rework the example to get your desired effect.

I don't see why this solution should help, but you are free to try.

as stated

put it inside a container view (FrameLayout, for example)
--@AndroidDeveloperLB

the example I posted shows how to force dimensions which may or may not be useful...hard to say without seeing how @axelfran is trying to get it done...so the example I provide maybe somewhat unrelated idk
