@mecoFarid can you explain it how to do properly ? What are the params ? And if @armcha doesn't accepts it, how can I use yours ? Since I didn't found any implementation methods on your fork.

Download the lib from here and unzip it. Then follow this StackOverflow question to add it as an external library. In this question, use Approach 2) part. While following steps in this question choose Import Module instead of New Module on step 1 and choose Android Library instead of Import JAR/.AAR Package on step 2. Then browse the unzipped folder you've just downloaded. The next steps are the same with ones stated in the question. That's it. Now just use SpaceNavigationView in your .xml, shadow will be applied by default you don't have to define additional parameters for a shadow to be visible.

@mecoFarid thanks for your reply. I know how to download the zip and use the library. I was just looking for simple implementation methods. Anyways, if the shadow occurs by default, what is its value in dp ? Can you share an image to get an idea of elevation effect. Also, it would be great if there is a method to provide own value for elevation. Doesn't matters, if it would be from XML or directly from JAVA code.

@vishalroygeek default Material elevation for AppBar. Since there is no parameter for shadow length in AppBar either. I will provide two options hasShadow=true/false but length will not be dynamic as per Material design requirements. Yet, I will add one more option to make it look like BottomNavigation. I mean single line along the border; parameter will be 'hasBorder=true/false'. I'm not thinking of implementing those in a couple of days, but will do it in the near future for people who're still interested.

@mecoFarid that's cool to add those params. But i would request you to add dynamic elevation param as well. Because sometimes some UI elements need to stand out more than it should. So, providing dynamic elevation would be great. You can also see that most of the UI elements have the elevation param. And it really helps in many cases. Anyways, you did a great job buddy. And let me know when you make the suitable changes ☺️
