RatingBar - 根据评级更改星星颜色 - Lollipop 问题

Question

[编辑 3] - 现在工作 根据@sJy 的建议，更改了如下代码：

 LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar)); // Partial star
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar));
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(0)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorPrimary));
                    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                        layerDrawable.getDrawable(1).setTint(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar));
                        layerDrawable.getDrawable(2).setTint(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar));
                        layerDrawable.getDrawable(0).setTint(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorPrimary));
                    } else {
                        layerDrawable.getDrawable(2).setColorFilter(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar), PorterDuff.Mode.SRC_ATOP);
                    }

我正在使用 AppCompatRatingBar 来显示用户选择的评级。 此代码在 KitKat 和 Marshmallow 中运行良好，但在 Lollipop 中星星的颜色不会改变。

请看下面的图片和代码：

奇巧 - 4 星

棒棒糖 - 点击两颗星

棉花糖 - 3星级

代码：

ratingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {


                if ((int) rating == 1) {

                    ratingBar.setNumStars(5);
                    ratingBar.setProgress(1);
                    ratingBar.setRating(1);

                    LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar)); 
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar));

                    }else {
                        layerDrawable.getDrawable(2).setColorFilter(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorOneStar), PorterDuff.Mode.SRC_ATOP);
                    }

                    textViewRating.setText(getResources().getString(R.string.worst));

                } else if ((int) rating == 2) {

                    ratingBar.setNumStars(5);
                    ratingBar.setProgress(2);
                    ratingBar.setRating(2);

                    LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

                    }

                    textViewRating.setText(getResources().getString(R.string.poor));
                } else if ((int) rating == 3) {

                    ratingBar.setNumStars(5);
                    ratingBar.setProgress(3);
                    ratingBar.setRating(3);

                    LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorThreeStars)); 
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorThreeStars));
                    }else {
                        layerDrawable.getDrawable(2).setColorFilter(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorThreeStars), PorterDuff.Mode.SRC_ATOP);
                    }

                    textViewRating.setText(Html.fromHtml(getResources().getString(R.string.onetime_watch_one_line)));
                } else if ((int) rating == 4) {

                    ratingBar.setNumStars(5);
                    ratingBar.setProgress(4);
                    ratingBar.setRating(4);

                    LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorFourStars)); 
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorFourStars));
                    }else {
                        layerDrawable.getDrawable(2).setColorFilter(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorFourStars), PorterDuff.Mode.SRC_ATOP);
                    }

                    textViewRating.setText(getResources().getString(R.string.good));
                } else if ((int) rating == 5) {

                    ratingBar.setNumStars(5);
                    ratingBar.setProgress(5);
                    ratingBar.setRating(5);

                    LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();

                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorFiveStars)); 
                        DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorFiveStars));
                    }else {
                        layerDrawable.getDrawable(2).setColorFilter(ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorFiveStars), PorterDuff.Mode.SRC_ATOP);
                    }

                    textViewRating.setText(getResources().getString(R.string.excellent));
                }

            }

        });

[编辑 1] 根据@Sohail 的建议，我补充说

DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(0)), ContextCompat.getColor(PostMovieReviewActivity.this, R.color.colorPrimary));

单击 RatingBar 时，它会消失。 为了澄清起见，我为 RatingBar 添加了背景颜色。

之前

之后

还没解决！！！

[编辑 2] 添加 AppCompatRatingBar xml，如果有帮助：

 <android.support.v7.widget.AppCompatRatingBar
                    android:id="@+id/ratingBar"
                    style="?android:attr/ratingBarStyle"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center"
                    android:layout_marginBottom="8dp"
                    android:background="@color/colorFiveStars"
                    android:isIndicator="false"
                    android:max="5"
                    android:numStars="5"
                    android:stepSize="1" />

风格有什么变化，问题的根源？

Answer 1

在lollipop工作设置所有状态Empty star Half star Full star评级变化。

LayerDrawable layerDrawable = (LayerDrawable) ratingBar.getProgressDrawable();
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(0)), Color.WHITE);   // Empty star
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(1)), Color.parseColor("#757675")); // Partial st
DrawableCompat.setTint(DrawableCompat.wrap(layerDrawable.getDrawable(2)), Color.parseColor("#757675"));  // Full

Answer 2

尝试使用setTint()直接设置 Tint

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    layerDrawable.getDrawable(1).setTint(getResources().getColor(R.color.colorOneStar));
    layerDrawable.getDrawable(2).setTint(getResources().getColor(R.color.colorOneStar)); 
}

注意：不推荐使用 getColor(int) 但它仍然有效（在 Lollipop、Marshmallow 中测试）

Answer 3

奇怪的是 Lolipop 有这个问题，不知道为什么！ 我通过使用它摆脱了这个问题，它适用于 Lolipop 以及所有的 Lolipop 前后。

使用要用于 RatingBar 的颜色创建一个 ColorState

final ColorStateList colorStateList = ColorStateList.valueOf(<int color value>)

然后使用 ViewCompat

ViewCompat.setBackgroundTintList(<Your RatingBar>,colorStateList)
