Introduction

• This series will be an informal demonstration of any problems I face or any observations I make while developing Android apps. Each blog post in this series will be unique and separate from the others, so feel free to look around.

The problem

• If you an have worked with the LazyColumn like myself then you are probably familiar with the stickyHeader. Which allows us to create code like this:

LazyColumn {
            stickyHeader {
               Text("BEHOLD THE STICKY HEADER!")
                }
            items(35) { index ->
                Text(text = "Item: $index",fontSize = 30.sp)
            }

        }

• The code above will allow the header to stay on screen even when the user scrolls to the bottom of the LazyColumn
• But where is the stickyFooter?!?!?!

The Sticky footer

• As it turns out there is no stickFooter{} api, which is a little disappointing. But that means we just have to get a little creative with the Box composable. Ultimately we are just going to wrap a Box around out LazyColumn and just position out footer code at the bottom of the box. Like so:

@Composable
fun FooterTesting(){
    Box(modifier = Modifier.fillMaxSize()){
        LazyColumn(){
             stickyHeader {
                  Text("BEHOLD THE STICKY HEADER!")
                }
            items(35) { index ->
                Text(text = "Item: $index",fontSize = 30.sp)
            }
        }
        Column(
            modifier = Modifier.fillMaxWidth().align(Alignment.BottomCenter).background(Color.Red),
        ){
            Text("It is I, The Sticky Footer", fontSize = 30.sp)
        }

    }

}

• There are two things I want to point out here. 1) The Box is wrapped around the LazyColumn. 2) Out sticky footer code is outside of the LazyColumn but inside the Box
