I got error on trying to set dynamic rating bar view in AlertDialog

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

 rtb = LayoutInflater.from(getContext()).inflate(R.layout.ratingbar_dialog, null);
    rb = (RatingBar) rtb.findViewById(R.id.rtbDialog);

    ad = new AlertDialog.Builder(getContext());
    ad.setView(rtb);

    ll1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            ad.setMessage("Rate Price");

            ad.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {

                    dialogInterface.dismiss();
                }
            });
            ad.setPositiveButton("Submit", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    rtbPrice.setRating(rb.getRating());
                }
            });
            ad.show();
        }
    });

Answer 1

Because each time you call ad.show() , a new dialog will be created and the same view rtb will be added as dialog content (So the 1st time works, then exception was raise in the 2nd time).
To fix it:

• you can move all the code from inflate to setView into the onClick method
• OR inside onClick , remove rtb from it's parent:
  if (rtb.getParent() instanceOf ViewGroup) { ((ViewGroup) rtb.getParent()).removeView(rtb); }
• OR refactor your code to let it's only create and show one dialog.

Answer 2

Don't inflate the view . . Set the xml via setContentView() and access the rating bar via FindviewbyId()
