在Android的位图和绘制对象之间的区别是什么？ [英] What is the difference between Bitmap and Drawable in Android?

问题描述

我GOOGLE了，但我找不到任何物品描述有关Android的位图和绘制对象之间的区别。

I googled but i couldn't find any article to describe about the difference between Bitmap and Drawable in Android.

推荐答案

一个位图是位图图像的再presentation（类似java.awt.Image中）。可拉伸的东西，可以得出的抽象。这可能是一个位图（包裹起来作为一个 BitmapDrawable ），但它也可以是单色，其它可绘制对象的集合，或任何数量的其他结构。

A Bitmap is a representation of a bitmap image (something like java.awt.Image). A Drawable is an abstraction of "something that can be drawn". It could be a Bitmap (wrapped up as a BitmapDrawable), but it could also be a solid color, a collection of other Drawable objects, or any number of other structures.

大多数Android的UI框架的喜欢和拖拉的对象，而不是位图对象一起工作。视图可以接受任何可绘制对象作为背景。一个ImageView的可以显示前景绘制对象。作为资源存储的图像被加载拖拉的对象。

Most of the Android UI framework likes to work with Drawable objects, not Bitmap objects. A View can accept any Drawable as a background. An ImageView can display a foreground Drawable. Images stored as resources are loaded as Drawable objects.
