android - 从位图创建可绘制对象

Question

全部，

按照建议here我需要从我的位图中制作一个可绘制对象。但是当我尝试使用时:

 Drawable d = new Drawable( my_bmp);

它表明这个构造函数已被弃用，取而代之的是:

 Drawable(Bitmap bmp, int resourceId)

我还能如何使用位图制作可绘制对象？

谢谢。

Answer 1

你可以使用

Drawable d = new BitmapDrawable(getResources(), my_bmp);

A Drawable that wraps a bitmap and can be tiled, stretched, or aligned. You can create a BitmapDrawable from a file path, an input stream, through XML inflation, or from a Bitmap object.

BitmapDrawable(Resources res, Bitmap 位图)

Create drawable from a bitmap, setting initial target density based on the display metrics of the resources.
