Android Studio：固定页脚固定在底部

Question

I'm currently working on a layout in Android Studio but there's a problem that I need to fix.. I want to make my layout be locked to the bottom, just like Facebook which has a layout-bar at the bottom, no matter how much you scroll, it wont move.

Right now my code looks like this, but the "goButtonLayout" keeps going out of screen.. Anyone got an idea?

<LinearLayout

Answer 1

Try like this better to use Relative Layout for this
