[英]RatingBar change star value rating worth
I am using the Android SDK RatingBar and trying to do 5 stars where each star is worth the value of 2, but it doesn't work. 我正在使用Android SDK RatingBar并尝试做5星,其中每颗星的价值都为2,但它不起作用。 I want the rating "8" to fill only 4 stars, but it fills up all 5. Do I need to use a third-party library to solve this issue?
我希望评级“ 8”仅填充4星,但它填充全部5星。是否需要使用第三方库来解决此问题?
<RatingBar
android:id="@+id/user_rating_bar"
android:isIndicator="true"
android:rating="8"
android:stepSize="0.01"
android:max="10"
android:numStars="5"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
I think you can do this way: 我认为您可以这样做:
<RatingBar
android:id="@+id/ratingBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:stepSize="0.5"
android:rating="2.5"
android:numStars="5"
/>
If you use a stepSize
value of 0.5
, with 5 stars you have 10 steps to fill, in this way each 0.5
is half a star and a rating of 8 * stepSize
will fill only 4 stars instead of 5. 如果您使用
stepSize
值为0.5
,有5个星星,则要填充10个步骤,因此,每个0.5
都是半颗星星,并且等级8 * stepSize
将仅填充4个星星而不是5个星星。
In one line: 一行:
ratingBar.setRating(8 * stepSize);
