# RoundedDrawable added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions) belongs to Maven artifact com.android.support:wear:28.0.0-alpha1 Summary:[XML Attrs](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#lattrs)\|[Ctors](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#pubctors)\|[Methods](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#pubmethods)\|[Protected Methods](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#promethods)\|[Inherited Methods](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#inhmethods)\|[\[Expand All\]](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#) # RoundedDrawable | This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ` public class RoundedDrawable ` ` `` extends `[Drawable](https://developer.android.com/reference/android/graphics/drawable/Drawable.html)` `` ` |---|---|---------------------------------------------| | java.lang.Object ||| | ↳ | [android.graphics.drawable.Drawable](https://developer.android.com/reference/android/graphics/drawable/Drawable.html) || | | ↳ | android.support.wear.widget.RoundedDrawable |
*** ** * ** *** Maintains and draws a drawable inside rounded rectangular bounds. The drawable set by the[setDrawable(Drawable)](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#setDrawable(android.graphics.drawable.Drawable))method will be drawn within the rounded bounds specified by[setBounds(Rect)](https://developer.android.com/reference/android/graphics/drawable/Drawable.html#setBounds(android.graphics.Rect))and[setRadius(int)](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#setRadius(int))when the[draw(Canvas)](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#draw(android.graphics.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)](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#setClipEnabled(boolean))method, it will clip the drawable to a rounded rectangle instead of resizing it. The[setRadius(int)](https://developer.android.com/reference/android/support/wear/widget/RoundedDrawable#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[getDrawable(int)](https://developer.android.com/reference/android/content/Context.html#getDrawable(int))method. #### Syntax: ``` ```
