I have a view which contains multiple textviews which will be "part of the ticket", but when I increase one of the textviews number of lines from 1 to 2, it works on the preview, but in real-time execution the resize doesn't work.

Your GitHub release mentions that 1.1.2 is on androidx but the actual artifact in maven references the old support lib (See pom.xml here: https://search.maven.org/artifact/com.vipulasri/ticketview/1.1.2/aar)

Also noticed artifact was last updated in Feb 2021 while GH release was pushed Sep 2020, maybe the artifact was inadvertently overwritten?

Paint provide setShadowLayer https://developer.android.com/reference/android/graphics/Paint.html#setShadowLayer(float, float, float, int) for customized shadow. Use this method can remove the api version restriction and less code.

I'm using it in a RecyclerView and it crashes the app with this error?

 android.renderscript.RSIllegalArgumentException: Radius out of range (0 < r <= 25).

Here's the TicketView I'm using
it shows perfectly fine in the preview btw.

• The title says it all. Is there a built-in functionality that lets the user export the View into some kind of an image? The basic idea is to make it shareable through android intent. I am willing to work on something if it's not yet available or not in the works.

Hi, first thanks for creating such an awesome library.

Is it possible to change the attribute names so it won't collide with other libraries? (like adding ticketview_ or ticket as a prefix(like the ticketElevation?)

I want to use this library but currently it attributes collides with other libraries i am using. (in my case the orientation resource name has conflicts)

AGPBI: {"kind":"error","text":"Attribute "orientation" already defined with incompatible format.","sources":[{"file":"/Users/xxxx/.gradle/caches/transforms-1/files-1.1/{other-library-name}/f85a8ad0b0222b4a35fd6da2e9a9be73/res/values/values.xml","position":{"startLine":86,"startColumn":4,"startOffset":5685,"endColumn":51,"endOffset":5732}}],"original":"","tool":"AAPT"}
AGPBI: {"kind":"error","text":"Original attribute defined here.","sources":[{"file":"/Users/xxx/.gradle/caches/transforms-1/files-1.1/{other-library-name}/f85a8ad0b0222b4a35fd6da2e9a9be73/res/values/values.xml","position":{"startLine":86,"startColumn":4,"startOffset":5685,"endColumn":51,"endOffset":5732}}],"original":"","tool":"AAPT"}

Stating from here
https://developer.android.com/studio/projects/android-library

Resource merge conflicts
The build tools merge resources from a library module with those of a dependent app module. If a given resource ID is defined in both modules, the resource from the app is used.
If conflicts occur between multiple AAR libraries, then the resource from the library listed first in the dependencies list (toward the top of the dependencies block) is used.
To avoid resource conflicts for common resource IDs, consider using a prefix or other consistent naming scheme that is unique to the module (or is unique across all project modules).

How to set color for shadow TicketView

first of all, congratulations for your repository. I'm trying to use with the recycler view and create a list view of ticket view. But it is not displayed. Do you have a similar example?

Ticket View Not Display in nested scrollview
how to implement nested scroll view ?

Hi Vipul Asri, thanks for this nice view

but i have a question about how to use this view?

is there any gradle work or something to get this view as a library?

thanks again dude :)

Ticket view just disappears when you try to wrap it inside ScrollView

Does this library can support multiple divisions like for example i need 3 sections for my ticket? Thanks!

When I try to unit Test with robolectric, I got errors, I think it is about mocking...

I can not call as TicketView class and mock.

Error:

error: attribute ticketBorderColor (aka com.component.test:ticketBorderColor) not found.

How can we mock the view?

Can you support for this type of ticket, or you can show me how to change, i would be very appreciate, thanks :D

Can this be done?

I try to re-write the class but it is very hard to make it become a View Group can help update ? Thank YOU

Hi, I'm trying to use your library in my application but I'm having some issues about:

1. How can I populate the view? I've created in my XML layout, but how can I set an image and the various information I have to display?
2. Is it possible to have a sample code (the one inside your play store's app would be perfect)?
3. Also, I saw some code in this repo for example. Is it possible to use and have it in Java?
4. A better documentation or a wiki maybe is the most missing point in this library.

Let me know and thanks for your work!

How i can obtain this layout with this library?
ImageView with inverter rounded corners or based on shape of layout like view.setClipToOutline(true);
Thanks.

HI, I am unable to view on ticket view. if i used transparent background it gives gray color background in devices. please help me with including layout over ticketview
