How to extend the borders of a nested Framelayout?

Question

How to expand a nested Framelayout (or any other) on the screen to the very frames of the phone. There are a few pixels empty

Answer 1

1. View the displayed layout - most likely the indents are determined by one of the parent elements.
2. If the screen is completely confusing, you can enable "Display layout restrictions" in the developer settings and view it on the screen.
If it is absolutely necessary to get out of the parent view, you can specify the layoutMargin with a negative "-8dp", but be careful with this.
