newDrawable()
Creates a new Drawable instance from its constant state.
Note: Using this method means density-dependent properties, such as pixel dimensions or bitmap images, will not be updated to match the density of the target display. To ensure correct scaling, use newDrawable(android.content.res.Resources) instead to provide an appropriate Resources object.
|
Drawable |
newDrawable(res: Resources?)
Creates a new Drawable instance from its constant state using the specified resources. This method should be implemented for drawables that have density-dependent properties.
The default implementation for this method calls through to newDrawable().
|
Drawable |
newDrawable(res: Resources?, theme: Resources.Theme?)
Creates a new Drawable instance from its constant state using the specified resources and theme. This method should be implemented for drawables that have theme-dependent properties.
The default implementation for this method calls through to newDrawable(android.content.res.Resources).
