触发后刷新Android刷新评级栏

Question

在用户提交评分后尝试刷新评级栏时遇到问题。所以基本上我在我的其他活动上的某个按钮被触发时传递现有的评级金额：

viewDtlEventBtn.setOnClickListener(new OnClickListener(){
        public void onClick(View v){
            Object[] obj = new Object[2];
            obj[0] = String.valueOf(eventIDTV.getText());
            obj[1] = eventReviewModel;
            new GetEventDetailAsyncTask(new GetEventDetailAsyncTask.OnRoutineFinished() {
                public void onFinish() {
                    // Passing whole object with value into another activity
                    Intent eventDtlIntent = new Intent(context, EventDetailMain.class);
                    // Pass in a list of rating star together with amount
                    eventDtlIntent.putExtra("eventPopulateStarObj", populateRatingStar);
                    context.startActivity(eventDtlIntent);
                }
            }).execute(obj);
        }
    });

当我在onCreate（）时填充评级栏：

ratingStarList = (ArrayList<EventReview>) i
            .getSerializableExtra("eventPopulateStarObj");

public void populateRatingProgressBar() {
    int totalStar = 0;
    // Get the total amount of rate records
    for (int j = 0; j < ratingStarList.size(); j++) {
        if (ratingStarList.get(j).getStarAmt() != null) {
            totalStar += Integer.parseInt(ratingStarList.get(j)
                    .getStarAmt());
        }
    }

    txtTotalRate.setText(totalStar + " Ratings for this event");        
    // Set progress bar based on the each rates
    for (int i = 0; i < ratingStarList.size(); i++) {
        if (ratingStarList.get(i).getStarAmt() != null) {
            if (ratingStarList.get(i).getEventReviewRate().equals("5")) {
                pb5Star.setProgress(Integer.parseInt(ratingStarList.get(i)
                        .getStarAmt()));
            } else if (ratingStarList.get(i).getEventReviewRate()
                    .equals("4")) {
                pb4Star.setProgress(Integer.parseInt(ratingStarList.get(i)
                        .getStarAmt()));
            } else if (ratingStarList.get(i).getEventReviewRate()
                    .equals("3")) {
                pb3Star.setProgress(Integer.parseInt(ratingStarList.get(i)
                        .getStarAmt()));
            } else if (ratingStarList.get(i).getEventReviewRate()
                    .equals("2")) {
                pb2Star.setProgress(Integer.parseInt(ratingStarList.get(i)
                        .getStarAmt()));
            } else if (ratingStarList.get(i).getEventReviewRate()
                    .equals("1")) {
                pb1Star.setProgress(Integer.parseInt(ratingStarList.get(i)
                        .getStarAmt()));
            }
        }
    }
}

它填充正确。但是，我不确定在用户提交评级后如何刷新评级栏。以下是用户提交评级时的代码：

public void promptSubmitStar() {
    AlertDialog.Builder Dialog = new AlertDialog.Builder(getActivity());
    Dialog.setTitle("Confirm Rating");
    LayoutInflater li = (LayoutInflater) getActivity().getSystemService(
            Context.LAYOUT_INFLATER_SERVICE);
    View dialogView = li.inflate(R.layout.option_submit_star, null);
    txtPromptStarRate = (TextView) dialogView
            .findViewById(R.id.txtPromptStarRate);
    txtPromptStarRate.setText("Confirm to submit " + starRate
            + " stars for this event?");
    Dialog.setView(dialogView);
    Dialog.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            EventReview eventReviewModel = new EventReview();
            eventReviewModel.setEventID(eventID);
            eventReviewModel.setEventReviewBy(userID);
            eventReviewModel.setEventReviewRate(String.valueOf(starRate));
            new CreateEventReviewAsyncTask(context)
                    .execute(eventReviewModel);
            dialog.dismiss();
            // Disable the rating bar by setting a touch listener which
            // always return true
            ratingBar.setOnTouchListener(new OnTouchListener() {
                public boolean onTouch(View view, MotionEvent event) {
                    return true;
                }
            });
        }
    });

    Dialog.setNegativeButton("Cancel",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    dialog.dismiss();
                }
            });
    Dialog d = Dialog.show();
    EventDialogueBox.customizeDialogueBox(context, d);
}

有什么想法吗？提前谢谢。

使用setRating（starRate）;以编程方式在RatingBar上设置评级。
