Android : Cloning an ImagView

In my Activity i have a ImageView to show a picture. When i click the ImageView i want a Dialog to appear and to set the view of the Dialog to the ImageView.

I tried it that way:

 public static void showImageDialog(Context context, String title, ImageView imageView) {
    AlertDialog.Builder builder = new AlertDialog.Builder(context);

    builder.setTitle(title);
    builder.setCancelable(false);
    builder.setView(imageView);
    builder.setPositiveButton(context.getResources().getString(R.string.button_back), new DialogInterface.OnClickListener() {
        /**
         * 
         */
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });

    builder.create().show();
}

Unfortunately i cant set an ImageView in my Activity and in the Dialog at the same time:

11-03 13:29:49.648: E/AndroidRuntime(1560): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

So how can i create a copy or a clone of my ImagView. The following ofcourse does not work because its a reference:

ImageView temp = this.imageView;
