Android 评分栏超出对话框范围

Question

the rating bar inside my dialog box is going out of bounds

 final AlertDialog.Builder popDialog = new AlertDialog.Builder(ExercisesActivity.this);
 final RatingBar rb = new RatingBar(ExercisesActivity.this);
 popDialog.setIcon(android.R.drawable.btn_star_big_on);
 rb.setMax(6);
 popDialog.setTitle("Set Difficulty");
 popDialog.setView(rb);
 // Button OK
 popDialog.setPositiveButton(android.R.string.ok,
       new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int which) {
              //do things
       }

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

setMax() 没有效果

Answer 1

如果您将直接在 AlertDialog 中添加 RatingBar 那么它会导致有线输出，因为我们正在动态生成 Ratingbar 而不是设置宽度.

您可以通过将 LayoutParams 设置为您的 RatingBar 并将您的 RatingBar 添加到 LinearLayout 中并添加LinearLayout View 到 AlertDialog。

检查以下示例:

final AlertDialog.Builder popDialog = new AlertDialog.Builder(getActivity());
popDialog.setTitle("Set Difficulty");
popDialog.setIcon(android.R.drawable.btn_star_big_on);

LinearLayout linearLayout = new LinearLayout(ExercisesActivity.this);
LinearLayout.LayoutParams lParams = new LinearLayout.LayoutParams(
        LinearLayout.LayoutParams.WRAP_CONTENT,
        LinearLayout.LayoutParams.WRAP_CONTENT
);

final RatingBar rating = new RatingBar(ExercisesActivity.this);
rating.setLayoutParams(lParams);
rating.setNumStars(6);
linearLayout.addView(rating);

popDialog.setView(linearLayout);

// Button OK
popDialog.setPositiveButton(android.R.string.ok,
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            //do things
        }
    });
popDialog.create();
popDialog.show();

输出:
