I have problem with my app. I make a floating button with animation from YT tutorial. When I added this buttons my application can't start and crash.I made these buttons in content_main.xml and from this I am using binding. When I did this in another projekt without drawer everythig was working properly. Anyone know what is wrong?

    Why did you place an `inflate` call before the call to `super.onCreate`? And what's with the multiple `setContentView` calls? The last two of them even seem to be referring to the same layout. – Michael Jan 16 '21 at 22:01
  • I did because it was on tutorial. About this to setContentView a tried something to connect with my layout. A made a udpate of code beacsue when I created new ```override fun onCreate``` it is opening but now clicking ```addBtn``` don't make any action. – patrykk1797 Jan 16 '21 at 22:05
  • There's no point in doing `setContentView(R.layout.content_main)` since you already have `setContentView(binding.root)` – Michael Jan 16 '21 at 22:29
  • I deleted this setContentView like you said, and make setOnClickListener in one ```override fun onCreate```. I mantion that separately button and actiobar is working. But together in on function app can't turn on. – patrykk1797 Jan 16 '21 at 22:32
  • @Michael I change this, but I don't know how to make these two thing together in on ```override fun onCreate``` – patrykk1797 Jan 16 '21 at 22:50
  • @PatrykKwiatkowski check out [this answer at stackoverflow](https://stackoverflow.com/a/19952291/9701793) – rahat Jan 17 '21 at 08:10
  • Unfortunately it didn't help me. I don't know how to implement in ```onCreate``` My floatingbuttons from ```ContentMain.xml``` and navigationdrawer from another layout – patrykk1797 Jan 17 '21 at 11:01
