Floating action bar Align is not working in xml

This is my XML code and design output in the Android studio split mode. You can see a floating action bar at the end bottom of the display. But when I run the application the floating action bar goes to the top end.

The second image is the output when I run the application. But the same code when I run on another Project it's work. But in this project it's not working. But I need it in this project.

Solution

  • There's a problem with the FrameLayout. I mean which contains the Recycler Item. I gave FrameLayout the wrong height. However, the IDE showed me the correct height. But when I was trying to run, but it was not getting the full height on the devices. So everyone always be aware of this type of silly mistake.
