android - Difference between DrawableCompat and Drawable -


a couple of days ago support library version v22.1.0 released , among new things have seen drawablecompat.

now question difference between drawablecompat , normal drawable, benefits bring , when , how use it.

i have read chris banes' blog, lacking explain , how useful developers.

quoting blog post in question:

the drawable tinting methods added in lollipop super useful letting dynamically tint assets.

here, tinting refers theme.material/theme.appcompat approach of using grayscale drawables , applying tints, colorprimary or coloraccent, tie them custom theme app. used in lots of places, in particular many places accent color seen.

continuing blog post:

appcompat had own baked in implementation in v21 support library , we’ve extracted drawablecompat in support-v4 use.

hence, drawablecompat allows use tint-the-grayscale image appcompat-v7 does, tinting drawables, going api level 4. in contrast similar tinting methods available on drawable starting api level 21. in particular, if creating custom widgets and using appcompat-v7, might use drawablecompat allow widgets adopt app's color scheme.

what difference between drawablecompat , normal drawable

drawablecompat departs typical ...compat approach. classes notificationcompat.builder replacements progenitors (e.g., notification.builder). in case, drawablecompat applies changes, tint, drawable, other drawable "wrapped" drawablecompat. drawablecompat provides api , wrap/unwrap capabilities; drawable wrap() use in app, in lieu of using original grayscale drawable started with.
