Issue is because RatingBar width matches the parent view and it creates stars irrespective of number of stars, RatingBar should have width as wrap_content respect to the parent.

Try placing RatingBar inside LinearLayout and add LinearLayout to your popup Dialog.

public void ShowDialog()
{
    final AlertDialog.Builder popDialog = new AlertDialog.Builder(this);

    LinearLayout linearLayout = new LinearLayout(this);
    final RatingBar rating = new RatingBar(this);

    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT
    );
    rating.setLayoutParams(lp);
    rating.setNumStars(4);
    rating.setStepSize(1);

    //add ratingBar to linearLayout
    linearLayout.addView(rating);


    popDialog.setIcon(android.R.drawable.btn_star_big_on);
    popDialog.setTitle("Add Rating: ");

    //add linearLayout to dailog
    popDialog.setView(linearLayout);



    rating.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
        @Override
        public void onRatingChanged(RatingBar ratingBar, float v, boolean b) {
            System.out.println("Rated val:"+v);
        }
    });



    // Button OK
    popDialog.setPositiveButton(android.R.string.ok,
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    textView.setText(String.valueOf(rating.getProgress()));
                    dialog.dismiss();
                }

            })

            // Button Cancel
            .setNegativeButton("Cancel",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            dialog.cancel();
                        }
                    });

    popDialog.create();
    popDialog.show();

In your xml layout give

Height is wrap_content

Widhth is also wrap_content

And set numStars

You need use like this

final RatingBar rating = new RatingBar(this);
 LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams( LinearLayout.LayoutParams.WRAP_CONTENT,
 LinearLayout.LayoutParams.WRAP_CONTENT );
 rating.setLayoutParams(lp);
 rating.setNumStars(4);

The same issue solve through the xml, try like this

   <RatingBar 
 enter code hereandroid:id="@+id/ratingBar"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:numStars="4" android:stepSize="1.0"
 android:rating="2.0" />

Then it will work...

Use rating.setNumStars(4); instead of rating.setMax(4);
