Make the RatingBar secondary color opaque

Question

I'm trying to make the un-filled stars in the RatingBar an opaque color, but it seems like a tall task consisting of tint lists and PorterDuff Modes. Is there a rock solid way to make the un-filled stars of a RatingBar a truely opaque color?

val color = ContextCompat.getColor(context, android.R.color.white)
ratingBar.secondaryProgressTintList = ColorStateList.valueOf(white)
ratingBar.secondaryProgressTintMode = PorterDuff.Mode.OVERLAY //whats the sauce?

The un-filled color is still transparent, and the background of the view is half white!

Also, I think you want to be settings the progress background color, not the secondary progress color. — TheWanderer, Commented Sep 7, 2018 at 1:01
the progressBackgroundTintMode to ADD gives it an entirely white background, to MULTIPLY, it does nothing. — Tyler, Commented Sep 7, 2018 at 1:05

The stars in a RatingBar are simply a LayerDrawable. The key to setting the color of unfilled stars is to get a handle on the index within the LayerDrawable that contains a description of the drawable for unfilled stars (index = 0). Once we have that drawable, we can color it with "Drawable#setTint()" for API 21+ or with "Drawable#setColorFilter()" for API <21.

The following example sets the unfilled stars to an opaque green:

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        RatingBar ratingBar = findViewById(R.id.ratingBar);
        LayerDrawable stars = (LayerDrawable) ratingBar.getProgressDrawable();
        int unfilledColor = getResources().getColor(android.R.color.holo_green_dark);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            stars.getDrawable(0).setTint(unfilledColor);
        } else {
            stars.getDrawable(0).setColorFilter(unfilledColor, PorterDuff.Mode.SRC_ATOP);
        }
    }
}

you can achieve this by creating a custom drawable resource file,

create new file in drawable directory with name rating_state.xml and paste this code

<?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/blank_star" /> <!-- here is drawable you should add blank image -->
    <item android:id="@android:id/secondaryProgress" android:drawable="@drawable/blank_star" />
    <item android:id="@android:id/progress" android:drawable="@drawable/full_star" /> <!-- here is drawable you want to show when rating selected -->
</layer-list>

then in your rating bar add property:

android:progressDrawable="@drawable/rating_state"

I think this might be the library you are looking for.

Example:

<com.iarcuschin.simpleratingbar.SimpleRatingBar
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:srb_borderColor="@android:color/transparent"
    app:srb_fillColor="@color/colorAccent"
    app:srb_numberOfStars="5"
    app:srb_rating="3"
    app:srb_starBackgroundColor="@color/colorPrimary"
    app:srb_starSize="40dp"
    app:srb_stepSize="0.5" />

Result:

The view can be configured as follows:

Set stars fill color in normal state with app:srb_fillColor / setFillColor(@ColorInt int)

Set stars background color in normal state with app:srb_starBackgroundColor / setStarBackgroundColor(@ColorInt int)

Set stars fill color in pressed state with app:srb_pressedFillColor / setPressedFillColor(@ColorInt int)

Set stars background color in pressed state with app:srb_pressedStarBackgroundColor / setPressedStarBackgroundColor(@ColorInt int)
