如何在android中獲取原始文件或原始目錄？

Question

我想試試oobjloader。 （免費波形3D格式加載器）我加載了第一個.obj，但沒有找到原始目錄。 （或只是沒有找到該文件）

  Uri url = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.cube1); 
      String filename = url.toString(); 

      try { 
       Build builder = new Build(); 
       Parse obj = new Parse(builder, filename); 
      } catch (java.io.FileNotFoundException e) { 
       System.out.println("trace FileNotFoundException loading file " + filename + ", e=" + e); 
       e.printStackTrace(); 
      } catch (java.io.IOException e) { 
       System.out.println("trace IOException loading file " + filename + ", e=" + e); 
       e.printStackTrace(); 
      } 

如何獲得原始文件目錄url？

錯誤：

我也試過其他格式，但沒有幫助。

"android.resource://" + getPackageName() + "/raw/cube1" 
"android.resource://" + getPackageName() + "/raw/cube1.obj" 

Thx all answare。

If wanna use the cube1.obj file from raw, you can do it this way 

     InputStream in = null; 
     OutputStream out = null; 
     File outFile = null; 
     try 
     { 
      in = context.getResources().openRawResource(R.raw.cube1); 
      outFile = new File(<path where you are going to store this raw file>, <what will be name of file>); 
      out = new FileOutputStream(outFile); 
      byte[] buffer = new byte[BBConstants.KILO_VALUE]; 
      int read; 
      while((read = in.read(buffer)) != -1) 
      { 
       out.write(buffer, 0, read); 
      } 
     } 
    } 
    catch(IOException e) 
    { 

    } 

現在outFile將包含您的cube1.obj數據，您可以在要使用的位置使用它。
