我得到这个问题的解决方案，在这里，我的答案

i got solution for this problem, Here my answer

private void saveImagesIntoGallery(){
        BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable();
        Bitmap bitmap = drawable.getBitmap();
       // File sdCardDirectory = Environment.getExternalStorageDirectory();// its stores under sdcard not in a specific path
        String sdCardDirectory = Environment.getExternalStorageDirectory().toString()+"/Pictures/";
        String url = arrayForImages[i].toString();
        String file = url.substring(url.lastIndexOf('/')+1);
        System.out.println("PATH NAME"+sdCardDirectory);
        File image = new File(sdCardDirectory, file);
        boolean success = false;

        // Encode the file as a PNG image.
        FileOutputStream outStream;
        try {

            outStream = new FileOutputStream(image);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream); 
            /* 100 to keep full quality of the image */
            outStream.flush();
            outStream.close();
            success = true;
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        if (success) {
            Toast.makeText(getApplicationContext(), "Image saved with success",
                    Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(getApplicationContext(),
                    "Error during image saving", Toast.LENGTH_LONG).show();
        }
    }
