EdgeTreatment
extends Object
java.lang.Object | |
↳ | com.google.android.material.shape.EdgeTreatment |
A basic edge treatment (a single straight line). Sub-classed for custom edge treatments.
Note: For edge treatments which result in a concave shape, the parent view must disable
clipping of children by calling ViewGroup.setClipChildren(boolean)
, or by
setting `android:clipChildren="false"` in xml. `clipToPadding` may also need to be false if there
is any padding on the parent that could intersect the shadow.

getEdgePath
public void getEdgePath (float length, float center, float interpolation, ShapePath shapePath)
Generates a ShapePath
for this edge treatment.
EdgeTreatments have an origin of (0, 0) and a destination of (0, length) (i.e. they represent the top edge), and are automatically rotated and scaled as necessary when applied to other edges. Only the horizontal, top EdgeTreatment needs to be defined in order to apply it to all four edges.
Parameters | |
---|---|
length |
float : the length of the edge. |
center |
float : the distance to the center of the edge. This takes into account any offset added
by the proceeding corner. Drawing anything at (center, 0) will be center aligned with the
shape. Normally you'll want to use this instead of length / 2. |
interpolation |
float : the interpolation of the edge treatment. Ranges between 0 (none) and 1
(fully) interpolated. Custom edge treatments can implement interpolation to support shape
transition between two arbitrary states. Typically, a value of 0 indicates that the custom
edge treatment is not rendered (i.e. that it is a straight line), and a value of 1
indicates that the treatment is fully rendered. Animation between these two values can
"heal" or "reveal" an edge treatment. |
shapePath |
ShapePath : the ShapePath that this treatment should write to.
