Flow

public class Flow
extends View

java.lang.Object
↳	android.view.View
	↳	androidx.constraintlayout.helper.widget.Flow

Flow VirtualLayout. Added in 2.0 Allows positioning of referenced widgets horizontally or vertically, similar to a Chain. The elements referenced are indicated via constraint_referenced_ids, as with other ConstraintHelper implementations. Those referenced widgets are then laid out by the Flow virtual layout in three possible ways:

wrap none : simply create a chain out of the referenced elements
wrap chain : create multiple chains (one after the other) if the referenced elements do not fit
wrap aligned : similar to wrap chain, but will align the elements by creating rows and columns

As VirtualLayouts are ConstraintHelpers, they are normal views; you can thus treat them as such, and setting up constraints on them (position, dimension) or some view attributes (background, padding) will work. The main difference between VirtualLayouts and ViewGroups is that:

VirtualLayout keep the hierarchy flat
Other views can thus reference / constrain to not only the VirtualLayout, but also the views laid out by the VirtualLayout
VirtualLayout allow on the fly behavior modifications (e.g. for Flow, changing the orientation)

flow_wrapMode = "none"

This will simply create an horizontal or vertical chain out of the referenced widgets. This is the default behavior of Flow. XML attributes that are allowed in this mode:

flow_horizontalStyle = "spread|spread_inside|packed"
flow_verticalStyle = "spread|spread_inside|packed"
flow_horizontalBias = "float"
flow_verticalBias = "float"
flow_horizontalGap = "dimension"
flow_verticalGap = "dimension"
flow_horizontalAlign = "start|end"
flow_verticalAlign = "top|bottom|center|baseline

While the elements are laid out as a chain in the orientation defined, the way they are laid out in the other dimension is controlled by flow_horizontalAlign and flow_verticalAlign attributes.

flow_wrapMode = "chain"

Similar to wrap none in terms of creating chains, but if the referenced widgets do not fit the horizontal or vertical dimension (depending on the orientation picked), they will wrap around to the next line / column. XML attributes are the same same as in wrap_none, with the addition of attributes specifying chain style and chain bias applied to the first chain. This way, it is possible to specify different chain behavior between the first chain and the rest of the chains eventually created.

flow_firstHorizontalStyle = "spread|spread_inside|packed"
flow_firstVerticalStyle = "spread|spread_inside|packed"
flow_firstHorizontalBias = "float"
flow_firstVerticalBias = "float"

One last important attribute is flow_maxElementsWrap, which specify the number of elements before wrapping, regardless if they fit or not in the available space.

flow_wrapMode = "aligned"

Same XML attributes as for WRAP_CHAIN, with the difference that the elements are going to be laid out in a set of rows and columns instead of chains. The attribute specifying chains style and bias are thus not going to be applied.
