How to set android lock screen image

由 心已入冬 提交于 2019-11-26 14:39:03

How to convert a Drawable to a Bitmap?

由 送分小仙女□ 提交于 2019-11-25 22:23:12
问题 I would like to set a certain Drawable as the device\'s wallpaper, but all wallpaper functions accept Bitmap s only. I cannot use WallpaperManager because I\'m pre 2.1. Also, my drawables are downloaded from the web and do not reside in R.drawable . 回答1: This piece of code helps. Bitmap icon = BitmapFactory.decodeResource(context.getResources(), R.drawable.icon_resource); Here a version where the image gets downloaded. String name = c.getString(str_url); URL url_value = new URL(name);
