Actually i managed to do it try this:

 AlertDialog.Builder builder = new AlertDialog.Builder(this);
                 builder.setTitle("Make your selection");
                 builder.setItems(items, new DialogInterface.OnClickListener()
                 {
                    public void onClick(DialogInterface dialog, int item)
                    {
                       // Do something with the selection
                    }
                 });
                 AlertDialog alert = builder.create();
                 Window window = alert.getWindow();
                 WindowManager.LayoutParams lp = window.getAttributes();
                 lp.token = mInputView.getWindowToken();
                 lp.type = WindowManager.LayoutParams.TYPE_APPLICATION_ATTACHED_DIALOG;
                 window.setAttributes(lp);
                 window.addFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
                 alert.show();
