RoundedDrawable

public class RoundedDrawable
extends Drawable

java.lang.Object
   ↳ android.graphics.drawable.Drawable
     ↳ androidx.wear.widget.RoundedDrawable


Maintains and draws a drawable inside rounded rectangular bounds.

The drawable set by the setDrawable(Drawable) method will be drawn within the rounded bounds specified by Drawable.setBounds(Rect) and setRadius(int) when the draw(Canvas) method is called.

By default, RoundedDrawable will apply padding to the drawable inside to fit the drawable into the rounded rectangle. If clipping is enabled by the setClipEnabled(boolean) method, it will clip the drawable to a rounded rectangle instead of resizing it.

The setRadius(int) method is used to specify the amount of border radius applied to the corners of inner drawable, regardless of whether or not the clipping is enabled, border radius will be applied to prevent overflowing of the drawable from specified rounded rectangular area.

RoundedDrawable can be inflated from XML (supported above API level 24) or constructed programmatically. To inflate from XML, use Context.getDrawable(int) method.

Syntax:

 <?xml version="1.0" encoding="utf-8"?>

   xmlns:app="http://schemas.android.com/apk/res-auto"
