如何让 RatingBar 显示五颗星 [英] How to make RatingBar to show five stars

问题描述

我正在遵循如何添加 RatingBar 的标准示例.为了控制星星的数量，我尝试使用 android:numStars="5".问题是星星的数量似乎根本没有任何作用.在纵向布局中，我得到 6 颗星，当我翻转手机时，我得到大约 10 颗星.我试图在加载 xml 的 Activity (myBar.setNumStars(5)) 中设置星数，但该选项也没有成功.

I am following the standard example of how to add a RatingBar. To control the number of stars I tried to use android:numStars="5". The problem is that the number of stars doesn't seem to do anything at all. In portrait-layout I get 6 stars and when I flip the phone I get about 10 stars. I tried to set the number of stars in my Activity (myBar.setNumStars(5)) that loads the xml but there was no success with that option either.

所以我的问题是如何定义我的布局，使其只显示五颗星?设置 numStars 似乎不起作用.

So my question is how do I define my layout so that it will only show five stars? Set numStars doesn't seem to work.

推荐答案

<RatingBar
            android:id="@+id/rating"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            style="?android:attr/ratingBarStyleSmall"
            android:numStars="5"
            android:stepSize="0.1"
            android:isIndicator="true" />

在代码中

mRatingBar.setRating(int)
