How to check which button was pressed?

Question

Android

Hung the listener on Bottom Nav. I want that when I click on the desired tab, the corresponding fragment opens. To do this, I take the id from the MenuItem and check it in the switch. The studio issues the following warning:


Is it safe to do such a check, or is there a more reliable way?

Answer 1

do if() {} else if()...
or stop writing java and use kotlin.
Here the studio just tells you that this code will break in the future. It will not work incorrectly, but will simply stop compiling.
