All Implemented Interfaces:
```
public class FlowLayoutManager
extends RecyclerView.LayoutManager
                    
```
A RecyclerView.LayoutManager that lays out items in flow style: items are placed in a line until it is full, then a new line starts, like words in a paragraph.
Items can have different sizes. It supports predictive item animations, scroll and smooth scroll, auto measurement, left, right or center alignment (setAlignment), a limit of items per line (maxItemsPerLine, singleItemPerLine) and a limit of lines (maxLines).
```
recyclerView.setLayoutManager(new FlowLayoutManager()
        .setAlignment(Alignment.LEFT)
        .maxItemsPerLine(3));
```
