Android 如何制作更小的 RatingBar？

How to make a smaller RatingBar?

提问by Clem

I've added a RatingBarin a layout:

我在布局中添加了一个RatingBar：

<RatingBar 
    android:id="@+id/ratingbar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:numStars="5"
    android:stepSize="1.0"
    />  

But the default style for the rating bar is too large.
I've try to change it by adding the android style : style="?android:attr/ratingBarStyleSmall"

但是评分栏的默认样式太大了。
我尝试通过添加 android 样式来更改它：style="?android:attr/ratingBarStyleSmall"

But the result is too small and it's impossible to set a rate with this property.

但结果太小，无法使用此属性设置速率。

How could I do?

我怎么办？

The default RatingBar widget is sorta' lame.

默认的 RatingBar 小部件有点蹩脚。

The source makes reference to style "?android:attr/ratingBarStyleIndicator" in addition to the "?android:attr/ratingBarStyleSmall" that you're already familiar with. ratingBarStyleIndicatoris slightly smaller but it's still pretty ugly and the comments note that these styles "don't support interaction".

?android:attr/ratingBarStyleIndicator除了?android:attr/ratingBarStyleSmall您已经熟悉的“ ”之外，源还引用了样式“ ” 。 ratingBarStyleIndicator稍微小一点，但它仍然很丑，评论指出这些样式“不支持交互”。

You're probably better-off rolling your own. There's a decent-looking guide at http://kozyr.zydako.net/2010/05/23/pretty-ratingbar/showing how to do this. (I haven't done it myself yet, but will be attempting in a day or so.)

你可能最好自己动手。http://kozyr.zydako.net/2010/05/23/pretty-ratingbar/ 上有一份不错的指南，展示了如何执行此操作。（我自己还没有做过，但会在一天左右的时间里尝试。）

Good luck!

祝你好运！

p.s. Sorry, was going to post a link to the source for you to poke around in but I'm a new user and can't post more than 1 URL. If you dig your way through the source tree, it's located at frameworks/base/core/java/android/widget/RatingBar.java

ps 抱歉，本来打算发布一个源链接供您浏览，但我是新用户，不能发布超过 1 个 URL。如果您在源树中挖掘自己的方式，它位于 frameworks/base/core/java/android/widget/RatingBar.java

Just use:

只需使用：

android:scaleX="0.5"
android:scaleY="0.5"

Change the scale factor according to your need.

根据需要更改比例因子。

In order to scale without creating a padding on the left also add

为了在不创建左侧填充的情况下进行缩放，还添加

android:transformPivotX="0dp"

There is no need to add a listener to the ?android:attr/ratingBarStyleSmall. Just add android:isIndicator=falseand it will capture click events, e.g.

无需向?android:attr/ratingBarStyleSmall. 只需添加 android:isIndicator=false它就会捕获点击事件，例如

<RatingBar
  android:id="@+id/myRatingBar"
  style="?android:attr/ratingBarStyleSmall"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:numStars="5"
  android:isIndicator="false" />

I found an easier solution than I think given by the ones above and easier than rolling your own. I simply created a small rating bar, then added an onTouchListener to it. From there I compute the width of the click and determine the number of stars from that. Having used this several times, the only quirk I've found is that drawing of a small rating bar doesn't always turn out right in a table unless I enclose it in a LinearLayout (looks right in the editor, but not the device). Anyway, in my layout:

我找到了一个比我认为上面给出的更简单的解决方案，并且比滚动你自己的更容易。我只是创建了一个小的评分栏，然后向其中添加了一个 onTouchListener。从那里我计算点击的宽度并从中确定星星的数量。使用过多次后，我发现的唯一怪癖是，除非我将其包含在 LinearLayout 中（在编辑器中看起来正确，但在设备中看起来不正确），否则绘制小评级栏并不总是正确地显示在表格中. 无论如何，在我的布局中：

            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >
                <RatingBar
                    android:id="@+id/myRatingBar"
                    style="?android:attr/ratingBarStyleSmall"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:numStars="5" />
            </LinearLayout>

and within my activity:

在我的活动中：

    final RatingBar minimumRating = (RatingBar)findViewById(R.id.myRatingBar);
    minimumRating.setOnTouchListener(new OnTouchListener()
    { 
        public boolean onTouch(View view, MotionEvent event)
        { 
            float touchPositionX = event.getX();
            float width = minimumRating.getWidth();
            float starsf = (touchPositionX / width) * 5.0f;
            int stars = (int)starsf + 1;
            minimumRating.setRating(stars);
            return true; 
        } 
    });

I hope this helps someone else. Definitely easier than drawing one's own (although I've found that also works, but I just wanted an easy use of stars).

我希望这对其他人有帮助。绝对比自己画更容易（虽然我发现这也有效，但我只想轻松使用星星）。
