title: Additional toolbar at the bottom with Scroll View
body: <p>I want to have an additional Toolbar with elements in it (like a back buttom and another bottom to directly go into a certain activity) at the bottom of the layout. The problem is that I use a Scroll View inside a Constraint Layout. How can I insert such a layout file. I tried it by drag and dropping a toolbar in the Scroll View. However, as the Scroll View is bigger than the layout in the layout editor of Android Studio, I did not know where to put it. It is also important that the two toolbars should be fixed. So whenever I scroll down, the toolbars should be visible all the time. </p>
  
  <p>Update: Does nobody have an idea. I am still strugelling with that</p>
  
  <p>Here is the design I want to have (in a first step without any buttoms):
