我怎样才能改变星星的颜色，我怎样才能改变星星的大小？
步骤1：创建自己的样式，克隆一个现有样式（来自$ANDROID_HOME/platforms/$SDK/data/res/values/styles.xml），将它放在您自己的项目的styles.xml中，并在将小部件添加到布局时引用它。
步骤2：为LayerDrawable创建自己的RatingBar XML资源，指向用于条形图的适当图像。原始样式将指向您可以与之比较的现有资源。然后，调整您的风格以使用您自己的LayerDrawable资源，而不是内置资源。
现在你可以使用AppCompat v22.1.0以后的DrawableCompat动态着色所有类型的drawable，当你用一组drawable支持多个主题时很有用。例如：
LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(0)), Color.RED); // Empty star
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)), Color.GREEN); // Partial star
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)), Color.BLUE); // Full star
这是向后兼容到API 4.另见Chris Banes在Support Libraries v22.1.0上的博客文章
对于实际的大小和形状，您需要为适当的大小定义新的样式和图层列表drawable，正如其他人已经在上面回答的那样。
使用android:theme属性：
styles.xml
<style name="Theme.Rating" parent="Theme.AppCompat.Light">
<item name="colorAccent">@color/rating</item>
</style>
layout.xml
<android.support.v7.widget.AppCompatRatingBar
android:theme="@style/Theme.Rating"
android:numStars="5"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
只需从xml更改评级栏的颜色： -
android:progressTint="@color/your_color"
android:backgroundTint="@color/your_color"
android:secondaryProgressTint="@color/your_color"
要更改您只需要设置的颜色，请设置参数android：progressTint
<RatingBar
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginTop="15dp"
android:numStars="5"
android:rating="1"
android:progressTint="@android:/color/black"
android:layout_gravity="center"
/>
对于样式属性的大小。
最简单的方法：
android:progressTint="@color/color"
建立@ lgvalle的答案。
2015年更新
现在您可以使用DrawableCompat来着色所有类型的drawable。例如：
可绘制进度= ratingBar.getProgressDrawable（）; DrawableCompat.setTint（progress，Color.WHITE）;这与API 4向后兼容
LayerDrawable drawable = (LayerDrawable) getProgressDrawable();
Drawable progress = drawable.getDrawable(2);
DrawableCompat.setTint(progress, getResources().getColor(COLOR1));
progress = drawable.getDrawable(1);
DrawableCompat.setTintMode(progress, PorterDuff.Mode.DST_ATOP);
DrawableCompat.setTint(progress, getResources().getColor(COLOR1));
DrawableCompat.setTintMode(progress, PorterDuff.Mode.SRC_ATOP);
DrawableCompat.setTint(progress, getResources().getColor(COLOR2));
progress = drawable.getDrawable(0);
DrawableCompat.setTint(progress, getResources().getColor(COLOR2));
这将保持分数步骤颜色。
<!--For rating bar -->
<style name="RatingBarfeed" parent="Theme.AppCompat">
<item name="colorControlNormal">@color/colorPrimary</item>
<item name="colorControlActivated">@color/colorPrimary</item>
</style>
使用你自己的颜色
如果不添加新样式，您可以使用qazxsw poi中的色调颜色
RatingBar经过一些研究，我想出了这种方法来设置背景色调，间隙色调（例如：半星）和星色调颜色。
<RatingBar
android:id="@+id/ratingBar"
style="@android:style/Widget.Holo.RatingBar.Small"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:rating="4.5"
android:stepSize="0.5"
android:progressTint="@color/colorPrimary"/>
简单的解决方案，使用AppCompatRatingBar及其setProgressTintList方法来实现这一点，请参阅此LayerDrawable layers = (LayerDrawable) ratingBar.getProgressDrawable();
DrawableCompat.setTint(layers.getDrawable(0), 0x33000000); // The background tint
DrawableCompat.setTint(layers.getDrawable(1), 0x00000000); // The gap tint (Transparent in this case so the gap doesnt seem darker than the background)
DrawableCompat.setTint(layers.getDrawable(2), 0xffFED80A); // The star tint
以供参考。
在提到的博客上有点复杂，我使用了类似但更简单的方法。你需要3星图像（red_star_full.png，red_star_half.png和red_star_empty.png）和一个xml，这就是全部。
将这3张图片放在res / drawable上。
放下以下ratingbar_red.xml：
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background" android:drawable="@drawable/red_star_empty" />
<item android:id="@android:id/secondaryProgress" android:drawable="@drawable/red_star_half" />
<item android:id="@android:id/progress" android:drawable="@drawable/red_star_full" />
</layer-list>
最后，告诉你的评级栏定义使用这个，即
<RatingBar android:progressDrawable="@drawable/ratingbar_red"/>
而已。
我解决了以下问题：
answer
LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(0)),
Color.WHITE); // Empty star
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)),
Color.YELLOW); // Partial star
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)),
Color.YELLOW);
对我而言......
我找到了一个根据你的主题改变星星颜色的简单解决方案。
转到这个网站：RatingBar mRating=(RatingBar)findViewById(R.id.rating);
LayerDrawable layerDrawable=(LayerDrawable)mRating.getProgressDrawable();
layerDrawable.getDrawable(2).setColorFilter(Color.parseColor
("#32CD32"), PorterDuff.Mode.SRC_ATOP);
选择主题颜色并创建星图。
使用上面的答案，我创建了一个可以轻松重复使用的快速静态方法。它仅旨在为激活的恒星着色进度颜色。未激活的恒星保持灰色。
http://android-holo-colors.com/
只需使用 public static RatingBar tintRatingBar (RatingBar ratingBar, int progressColor)if (ratingBar.getProgressDrawable() instanceof LayerDrawable) {
LayerDrawable progressDrawable = (LayerDrawable) ratingBar.getProgressDrawable();
Drawable drawable = progressDrawable.getDrawable(2);
Drawable compat = DrawableCompat.wrap(drawable);
DrawableCompat.setTint(compat, progressColor);
Drawable[] drawables = new Drawable[3];
drawables[2] = compat;
drawables[0] = progressDrawable.getDrawable(0);
drawables[1] = progressDrawable.getDrawable(1);
LayerDrawable layerDrawable = new LayerDrawable(drawables);
ratingBar.setProgressDrawable(layerDrawable);
return ratingBar;
}
else {
Drawable progressDrawable = ratingBar.getProgressDrawable();
Drawable compat = DrawableCompat.wrap(progressDrawable);
DrawableCompat.setTint(compat, progressColor);
ratingBar.setProgressDrawable(compat);
return ratingBar;
}
}
通过您的评级栏和颜色
如您所见，我使用DrawableCompat，因此它向后兼容。
编辑：此方法不适用于API21（请查看原因）。调用setProgressBar时，最终会出现NullPointerException。我最终在API> = 21上禁用了整个方法。
对于API> = 21，我使用SupperPuccio解决方案。
评级栏在运行时自动用于触摸星上的更改颜色。
首先在app \ src \ main \ res \ values \ styles.xml文件中添加样式：
getResources().getColor(R.color.my_rating_color)然后你的评级栏添加这样的主题：
<style name="RatingBar" parent="Theme.AppCompat">
<item name="colorControlNormal">@android:color/darker_gray</item>
<item name="colorControlActivated">@color/com_facebook_blue</item>
</style>
1）声明这个xml
<RatingBar
android:id="@+id/rating"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize="1"
android:theme="@style/RatingBar"/>
2）在style.xml中
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:layout_marginBottom="20dp"
android:background="#323232"
android:gravity="center_horizontal">
<com.example.android.custom_ratingbar.CustomRatingBar
android:id="@+id/coloredRatingBar5"
style="@style/coloredRatingBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="match_parent"
/>
</LinearLayout>
3)
<style name="coloredRatingBarStyleSmall">
<item name="indicator">false</item>
<item name="type">small</item>
</style>
6）评级有效---采用深色的任何图像因为它将用作不同评级的颜色透明度
rating_inactive - 使用浅背景拍摄上面图像大小相同的任何图像。当没有选择评级时将使用
更改星形边框颜色的一种非常简单的方法是使用xml参数：

我一直在寻找一种可靠的方法，至少要做到这一点一直到API 9。 “cast to LayerDrawble”解决方案对我来说似乎是一个冒险的解决方案，当我在2.3上的Android手机上测试它时，它成功投射但是对DrawableCompat.setTint（...）的调用没有任何影响。
加载可绘制资产的需求对我来说似乎也不是一个好的解决方案。
我决定编写自己的解决方案，这是一个扩展AppCompatRatingBar的类，使用自定义Drawable来编程绘制星星。它完全符合我的需求，我会发布它以防万一：
android:progressBackgroundTint=""

android:layout_below="@+id/profil_name"
android:layout_centerHorizontal="true"
android:layout_marginLeft="@dimen/dimen_4"

这样，星星将以白色着色。
使用此链接
<style name="WhiteRatingStar" parent="Base.Widget.AppCompat.RatingBar.Small">
<item name="colorAccent">@android:color/white</item>
</style>
将你的风格设定在价值/风格内（v-21）;
试试这个，如果你只想改变颜色：
RatingBar ratingBar = (RatingBar) findViewById(R.id.ratingBar);
LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
stars.getDrawable(2).setColorFilter(Color.YELLOW, PorterDuff.Mode.SRC_ATOP);
如前面的答案所示，改变评级栏的颜色并不容易。星星不是以编程方式绘制的，它们是具有固定大小和特定颜色渐变的图像。要更改颜色，您必须创建自己的不同颜色的星形图像，然后继续创建自己的可绘制XML资源，并使用setProgressDrawable（Drawable d）或XML属性android：progressDrawable将其传递给ratingsBar类。
最简单的方法对我有用......如果你正在扩展AppCompat Activity
在build.gradle中添加最新的appcompat库。
dependencies {
compile 'com.android.support:appcompat-v7:X.X.X' // where X.X.X version
}
使您的活动扩展android.support.v7.app.AppCompatActivity
public class MainActivity extends AppCompatActivity {
...
}
在styles.xml文件中声明自定义样式。
<style name="RatingBar" parent="Theme.AppCompat">
<item name="colorControlNormal">@color/indigo</item>
<item name="colorControlActivated">@color/pink</item>
</style>
通过android：theme属性将此样式应用于RatingBar。
<RatingBar
android:theme="@style/RatingBar"
android:rating="3"
android:stepSize="0.5"
android:numStars="5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
2015年更新
现在你可以使用DrawableCompat来着色所有类型的drawables。例如：
Drawable progress = ratingBar.getProgressDrawable();
DrawableCompat.setTint(progress, Color.WHITE);
这与API 4向后兼容
如果你想改变我使用的所有星星的颜色：
LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
stars.getDrawable(2).setColorFilter(getResources().getColor(R.color.starFullySelected), PorterDuff.Mode.SRC_ATOP);
stars.getDrawable(1).setColorFilter(getResources().getColor(R.color.starPartiallySelected), PorterDuff.Mode.SRC_ATOP);
stars.getDrawable(0).setColorFilter(getResources().getColor(R.color.starNotSelected), PorterDuff.Mode.SRC_ATOP);
从API 21上可以很容易地用这三行代码改变星星的颜色：
android:progressTint="@android:color/holo_red_dark"
android:progressBackgroundTint="@android:color/holo_red_dark"
android:secondaryProgressTint="@android:color/holo_red_dark"
这样做，你会改变：
Alex和CommonsWares发布的解决方案是正确的。 Android从未谈到的一件事是不同密度的正确像素大小。以下是基于光晕的每种密度所需的尺寸。
小星星
mdpi: 16px
hdpi: 24px
xhdpi: 32px
xxhdpi: 48px
中星
mdpi: 24px
hdpi: 36px
xhdpi: 48px
xxhdpi: 72px
大明星
mdpi: 35px
hdpi: 52px
xhdpi: 69px
xxhdpi: 105px
所以我一直在努力解决这个问题两个小时，我已经为所有API版本提出了一个可行的解决方案，其中还显示了半星评级。
private void setRatingStarColor(Drawable drawable, @ColorInt int color)
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
DrawableCompat.setTint(drawable, color);
}
else
{
drawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);
}
}
您使用此drawables顺序调用该方法：
LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
// Filled stars
setRatingStarColor(stars.getDrawable(2), ContextCompat.getColor(getContext(), R.color.foreground));
// Half filled stars
