Question

我想尝试oobjloader。（自由波3d格式加载器）我加载了第一个.obj，但没有找到原始目录。（或者只是没找到文件）

            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();
            }

如何获取原始文件dir url？

错误：

我也试过其他格式，但没有帮助。

"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) 
    {

    }

现在outFile将包含你的cube1.obj数据，你可以在你想要使用的地方使用它。
