Question

我需要在Android应用程序中获取可绘制图像的绝对路径或File对象。有没有办法做到这一点？

Drawable如下

context.getResources（）。getDrawable（R.drawable.back_button）

Answer 1

如果您的应用已安装在SD卡上，请尝试以下代码：

Bitmap bitMap = BitmapFactory.decodeResource(getResources(),R.id.img1);

File mFile1 = Environment.getExternalStorageDirectory();

String fileName ="img1.jpg";

File mFile2 = new File(mFile1,fileName);
try {
       FileOutputStream outStream;

       outStream = new FileOutputStream(mFile2);

       bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);

       outStream.flush();

       outStream.close();

} catch (FileNotFoundException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
} catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
}

String sdPath = mFile1.getAbsolutePath().toString()+"/"+fileName;

Log.i("hiya", "Your IMAGE ABSOLUTE PATH:-"+sdPath); 

File temp=new File(sdPath);

if(!temp.exists()){
       Log.e("file","no image file at location :"+sdPath);
}

Answer 2

Uri path = Uri.parse("android.resource://com.nikhil.material/" + R.drawable.image);

OR

Uri otherPath = Uri.parse("android.resource://com.nikhil.material/drawable/image");

OR

Uri path = Uri.parse("android.resource://"+BuildConfig.APPLICATION_ID+"/" + R.drawable.image);

Answer 3

可绘制资源在运行时添加到二进制文件，因此无法通过路径访问。你可以解码并使用drawables。

如果您需要可以在运行时通过路径访问的资源，请尝试使用assets文件夹。

希望这是有帮助的
