How can I set the color of android rating bar's stroke? (Not the color of the stars but the BORDER)

问题

I am an android beginner and I want to make my custom ratingBar.

Disclaimer: it's not a duplicate. because all the posts I have read asks about how to change colors of the star and how to remove the stroke. That is NOT what I want. I want to have the stroke and to be able to change the color of the border.

With a transparent and yellow stroke while empty, and yellow background and stroke for half and filled.

I do NOT want to use pngs. I have my own already but they are too small. I just dont want to ask the designer to make new ones if I can make the stars using only XML attributes and drawables.

<RatingBar
          android:id="@+id/thread_rating"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:isIndicator="true"
          android:numStars="5"
          android:progressBackgroundTint="@color/gray"
          android:progressTint="@color/gold"
          android:rating="2.5"
          android:secondaryProgressTint="@color/gray"
          android:stepSize="0.5"
          style="?android:attr/ratingBarStyleSmall"
          />

I work on this with another engineer. He also wrote code in a java file

private void setRatingBarStart(RatingBar rating_bar) {
LayerDrawable stars = (LayerDrawable) rating_bar.getProgressDrawable();
stars.getDrawable(2)
    .setColorFilter(getResources().getColor(R.color.gold),
        PorterDuff.Mode.SRC_ATOP); // for filled stars
stars.getDrawable(1)
    .setColorFilter(getResources().getColor(R.color.light_gray),
        PorterDuff.Mode.SRC_ATOP); // for half filled stars
stars.getDrawable(0)
    .setColorFilter(getResources().getColor(R.color.light_gray),
        PorterDuff.Mode.SRC_ATOP); // for empty stars

[So now it has a grey background, yellow for filled, and NO stroke now.

And I want it to have transparent background, yellow stroke and yellow for filled. Looks like this

I already know how to set the background transparent and to make it yellow. I just dont know how to set the stroke color. Thanks a lot!!!!

回答1:

Put all drawable color to Yellow(in your case getResources().getColor(R.color.gold) for all) for set strokes and background. (for background,secondary progress and progress)

RatingBar ratingBar = (RatingBar) findViewById(R.id.ratingBar);
        LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
        stars.getDrawable(2).setColorFilter(Color.YELLOW, PorterDuff.Mode.SRC_ATOP);
        stars.getDrawable(0).setColorFilter(Color.YELLOW, PorterDuff.Mode.SRC_ATOP);
        stars.getDrawable(1).setColorFilter(Color.YELLOW, PorterDuff.Mode.SRC_ATOP);

remove progressBackgroundTint,progressTint,secondaryProgressTint attributes from RatingBar no need of it.

<RatingBar
        android:id="@+id/ratingBar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:numStars="5"
        android:rating="2.5"/>

and result is ::

Hope this will help (pink color is just background color)

after set drawable 1 and 0 to red:

RatingBar ratingBar = (RatingBar) findViewById(R.id.ratingBar);
        LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
        stars.getDrawable(2).setColorFilter(Color.YELLOW, PorterDuff.Mode.SRC_ATOP);
        stars.getDrawable(0).setColorFilter(Color.Red, PorterDuff.Mode.SRC_ATOP);
        stars.getDrawable(1).setColorFilter(Color.Red, PorterDuff.Mode.SRC_ATOP);

Don't use any library or style for that. Use bellow step you get the result.

create a file in drawable folder as custom_ratingbar.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/star_empty" />
 <item android:id="@android:id/secondaryProgress"
android:drawable="@drawable/star_empty" />
 <item android:id="@android:id/progress"
android:drawable="@drawable/star_full" />
</layer-list>

then use following in your RatingBar :

  <RatingBar
    android:id="@+id/ratingBarChef"
    style="?android:attr/ratingBarStyleSmall"
    android:numStars="5"
    android:stepSize="0.2"
    android:rating="3.0"
    android:progressDrawable="@drawable/custom_ratingbar"
    android:isIndicator="false"
    />

I think I actually found what you need. You will have to create a custom RatingBaras explained in this answer BUT you will have to use vector drawables and not standard ones.

You can download the 3 drawables (full, half and empty) on this website:

https://materialdesignicons.com/

Or by doing a right click on your res folder: --> New --> Vector asset on Android Studio.

Here are the 3 drawables XML in case you don't find them:

Full star:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:height="24dp"
android:width="24dp"
android:viewportWidth="24"
android:viewportHeight="24">
<path android:fillColor="#000" android:pathData="M12,17.27L18.18,21L16.54,13.97L22,9.24L14.81,8.62L12,2L9.19,8.62L2,9.24L7.45,13.97L5.82,21L12,17.27Z" />

Half star:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:height="24dp"
android:width="24dp"
android:viewportWidth="24"
android:viewportHeight="24">
<path android:fillColor="#000" android:pathData="M12,15.89V6.59L13.71,10.63L18.09,11L14.77,13.88L15.76,18.16M22,9.74L14.81,9.13L12,2.5L9.19,9.13L2,9.74L7.45,14.47L5.82,21.5L12,17.77L18.18,21.5L16.54,14.47L22,9.74Z" />

Empty star:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:height="24dp"
android:width="24dp"
android:viewportWidth="24"
android:viewportHeight="24">
<path android:fillColor="#000" android:pathData="M12,15.39L8.24,17.66L9.23,13.38L5.91,10.5L10.29,10.13L12,6.09L13.71,10.13L18.09,10.5L14.77,13.38L15.76,17.66M22,9.24L14.81,8.63L12,2L9.19,8.63L2,9.24L7.45,13.97L5.82,21L12,17.27L18.18,21L16.54,13.97L22,9.24Z" />

To change their size, just update the attributes height and width.

To change their color, just update the attribute fillColor and set your yellow color.
