我想读入位图我有我绘制的文件夹并将其存储为一个位图变量，这样我可以把它作为背景。请问这样做是最好的方式使用文件阅读器？像

I wanna read in a bitmap that I have in my drawable folder and store it as a Bitmap variable so that I can set it as a background. Would the best way to do this be using a "file reader"? like

  Bitmap decodeFile (String pathName) method

还是有办法只有这样设置：

Or is there a way to just set it like this:

  Bitmap bmp = R.drawable."bitmapFileName"; 

（我曾经试过，但返回一个int，只是想知道如果我是正确的轨道上）

(I have tried this but returns an int, just wondering if I was on the right track)

任何帮助将是巨大的：）

Any help would be great :)

推荐答案

的 R.drawable。bitmapFileName，着实只是一个整数，它是一个指数（静态整数）在项目的R舱（详见这里）。您可以从资源的文件夹中加载的位图是这样的：

The R.drawable."bitmapFileName" is, indeed, just an integer, for it is an index (static integer) at your project's R class (see more here). You can load your bitmap from the resources's folder like this:

Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.yourBitmap);

我发现在 Android的发展共同体这code。
