需要立即帮助！！以前的代码可以正常工作，但过了一会儿我注意到评级没有t work anymore and gives "the specified child already has a parent, call removeView() first..." on thealertDialog.show();` 行：

///// Rating bar initialising
    Context mContext = ShowActivity.this;
    LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
    layout = inflater.inflate(R.layout.custom_rate_dialog, (ViewGroup) findViewById(R.id.layout_root));

    final RatingBar rating_indicator = (RatingBar)findViewById(R.id.rating_bar_cafe_indicator);
    final float current_rating = (float)mDbHelper.getInt(mRowId, type, RATE_COLUMN);
    rating_indicator.setRating(current_rating);


    rateDialogBuilder = new AlertDialog.Builder(ShowActivity.this);
    rateDialogBuilder.setView(layout);
    rateDialogBuilder.setCancelable(false);
    rateDialogBuilder.setIcon(R.drawable.rate_star_med_on);
    rateDialogBuilder.setTitle("RATE IT!");
    rateDialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            rating_indicator.setRating(mDbHelper.getInt(mRowId, type, RATE_COLUMN));
            ((ViewGroup)layout.getParent()).removeView(layout);
            dialog.cancel();
        }
    });

    ratingText = (TextView) layout.findViewById(R.id.rate_text);
    rating = (RatingBar) layout.findViewById(R.id.rating_bar_cafe);
    rating.setRating(current_rating);
    rating.setStepSize(1);
    rating.setOnRatingBarChangeListener(ShowActivity.this);

    if ((int)current_rating != 0) ratingText.setText("Your rating: " + (int)current_rating); 

    Button rateButton = (Button) findViewById(R.id.button_rate); 
    rateButton.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {

            AlertDialog alertDialog = rateDialogBuilder.create(); 
            alertDialog.show();

        }
    });

    //////

奇怪的是，如果我打电话removeAllViews()或removeView()就在alertDialog.show();它没有崩溃但打开混乱的对话之前，我可以看到评级和当前活动或smth。此外，问题可能出在代码中的其他地方，因为它曾经可以正常工作，我应该寻找什么或如何更改它以使其工作的任何想法？

您得到的错误是您在将 a 添加View到父级之后将其添加到父级。

查看您的代码，它看起来像， 

layout = inflater.inflate(R.layout.custom_rate_dialog, (ViewGroup) findViewById(R.id.layout_root));

添加custom_rate_dialog到你layout_root。然后，当您这样做时，您将其添加到另一个父级rateDialogBuilder.setView(layout);

如果您只是想扩大该布局以将其设置为ViewforDialog那么就做

layout = inflater.inflate(R.layout.custom_rate_dialog, null);
