How about using following snippet ?

Drawable d = imageView.getBackground();
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();

File file = new File(Environment.getExternalStorageDirectory(), "fileName.ext");
outStream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();

Try this..

Change root.createNewFile(); to cachePath.createNewFile();

File root = Environment.getExternalStorageDirectory();
File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");
try {
    cachePath.createNewFile();
    FileOutputStream ostream = new FileOutputStream(cachePath);
    bitmap.compress(CompressFormat.JPEG, 100, ostream);
    ostream.close();
} catch (Exception e) {
    e.printStackTrace();
}

EDIT:

FileOutputStream ostream = new FileOutputStream(cachePath);

To get bitmap from imageview:

  imageview.buildDrawingCache();
    Bitmap bm=imageview.getDrawingCache();

To save it in a file:

 OutputStream fOut = null;
    Uri outputFileUri;
     try {
    File root = new File(Environment.getExternalStorageDirectory()
      + File.separator + "folder_name" + File.separator);
    root.mkdirs();
   File sdImageMainDirectory = new File(root, "myPicName.jpg");
    outputFileUri = Uri.fromFile(sdImageMainDirectory);
    fOut = new FileOutputStream(sdImageMainDirectory);
   } catch (Exception e) {
    Toast.makeText(this, "Error occured. Please try again later.",
      Toast.LENGTH_SHORT).show();
   }

   try {
    bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
    fOut.flush();
    fOut.close();
   } catch (Exception e) {
   }

add in manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

1 - you need an appropriate permission in amnifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

2- out.flush() check the out is not null..

3 -

String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + 
                            "/yourforlderName";
    File dir = new File(file_path);
if(!dir.exists())
    dir.mkdirs();
    File file = new File(dir, "yourforlderName" + image + ".png");
    FileOutputStream fOut = new FileOutputStream(file);

    bmp.compress(Bitmap.CompressFormat.PNG, 85, fOut);
    fOut.flush();
    fOut.close();

if you don't create directory in your sdcard then how to store images in sdcard of specific location? so please check this...i hope its useful to you.

Use this function to save in SD card:

private void SaveIamge(Bitmap finalBitmap) {

    String root = Environment.getExternalStorageDirectory().toString();
    File myDir = new File(root + "/saved_images");    
    myDir.mkdirs();
    Random generator = new Random();
    int n = 10000;
    n = generator.nextInt(n);
    String fname = "Image-"+ n +".jpg";
    File file = new File (myDir, fname);
    if (file.exists ()) file.delete (); 
    try {
           FileOutputStream out = new FileOutputStream(file);
           finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
           out.flush();
           out.close();

    } catch (Exception e) {
           e.printStackTrace();
    }
}

and add in manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
