android drawable from file path

Question

我有一个文件路径字符串形式为"e:\ ...\xxx.jpg"如何从中创建一个drawable？

Answer 1

您可以从字符串路径创建Drawable或Bitmap,如下所示:

 String pathName = "/path/to/file/xxx.jpg"; 
 Drawable d = Drawable.createFromPath(pathName);

对于位图:

String pathName = "/path/to/file/xxx.jpg";
bitmap b = BitmapFactory.decodeFile(pathName);
