How to set the custom size of the stars in RatingBar
提问by Marcin S.
I have already added a style
我已经添加了样式
<style name="myRatingBar" parent="@android:style/Widget.RatingBar">
<item name="android:minHeight">32dp</item>
<item name="android:maxHeight">32dp</item>
</style>
However instead of scaled stars I'm receiving cropped stars:
然而，我收到的不是缩放的星星，而是裁剪的星星：
Is there a way to change the size of the stars?
有没有办法改变星星的大小？

Android won't scale a rating bar icons. When you decrease the minHeightand maxHeightandroid will always crop the icons as shown on the picture. The workaround for it and seems to be the only one solution is to provide your own icons for stars with the desired dimensions and set the minHeightand maxHeightto the size of the icons.
Android 不会缩放评级栏图标。当您减少时minHeight，maxHeightandroid 将始终裁剪图标，如图所示。它的解决方法，似乎是唯一的解决方案是提供自己的图标恒星所需的尺寸和设置minHeight，并maxHeight以图标的大小。

Another approach would be scaling the widget:
另一种方法是缩放小部件：
android:scaleX="0.5"
android:scaleY="0.5"

I have same issue.All solutions I got does not work for multiple screen sizes. After spending hours I ended with following solution.
我有同样的问题。我得到的所有解决方案都不适用于多种屏幕尺寸。花了几个小时后，我以以下解决方案结束。
Just get drawable height which you want to use at runtime and set it to RatingBar. Here is sample code.
只需获取要在运行时使用的可绘制高度并将其设置为 RatingBar。这是示例代码。
Drawable starDrawable = getResources().getDrawable(R.drawable.YOUR_IMAGE);
int height = starDrawable.getMinimumHeight();
LayoutParams params = (LayoutParams) ratingBar.getLayoutParams();
params.height = height;
ratingBar.setLayoutParams(params);

This is not exactly an answer but I would like to show an alternative. Using a library called Iconifythat allow you to use scalable vector icons on android apps and with a simple method you can create awesome ratingbar with icons.
这不完全是一个答案，但我想展示一个替代方案。使用一个名为Iconify的库，它允许您在 android 应用程序上使用可缩放的矢量图标，并且通过一种简单的方法，您可以创建带有图标的很棒的评级栏。
The method
方法
public static String montarEstrellasValoracion(float valoration,int starSize) {
String result="";
float cont=1f;
for(float i=1f;i<=valoration;i++){
if(valoracion==0){
break;
}
cont=i;
if((cont+0.5f)>=(valoration) && valoracion!=5f){
result+="{fa-star "+starSize+"dp} ";
result+="{fa-star-half-o "+starSize+"dp} ";
cont++;
break;
}else if((cont+0.5f)<(valoration) && (cont+1f)>(valoration) && valoration!=5f){
result+="{fa-star "+starSize+"dp} ";
result+="{fa-star "+starSize+"dp} ";
cont++;
break;
}
if(cont<=5){
result+="{fa-star "+starSize+"dp} ";
}
}
for(float j=cont;j<5f;j++){
result+="{fa-star-o "+starSize+"dp} ";
}
if(valoration==0){
result+="{fa-star-o "+starSize+"dp}";
}
return result;
}
And then on the onCreate method:
然后在 onCreate 方法上：
IconTextView valoracion = (IconTextView)item.findViewById(R.id.id_icon_textview);
valoracion.setText(montarEstrellasValoracion(valoration,15));valoracion.setTextColor(Color.parseColor("#000");
valoracion.setText(montarEstrellasValoracion(valoration,15));valoracion.setTextColor(Color.parseColor("#000");
The icons are from another awesome site called Font Awesome
这些图标来自另一个很棒的网站Font Awesome

Maybe we can use the another alternative that android provides small size of rating stars. Adding style="@style/Widget.AppCompat.RatingBar.Small" to the RatingBar.
也许我们可以使用另一个替代方案，即 android 提供小尺寸的评级星级。将 style="@style/Widget.AppCompat.RatingBar.Small" 添加到 RatingBar。
<RatingBar
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/list_item_margin"
android:layout_marginLeft="@dimen/list_item_margin"
android:numStars="5"
android:isIndicator="true"
style="@style/Widget.AppCompat.RatingBar.Small"/>
