java - 十六进制字符串到颜色名称

Question

这个问题已经有答案了:

Convert RGB values to color name (8 个回答)

已关闭 5 年前。

这不是一个重复的问题，我知道有人问了一些像我一样的问题，但我需要有关如何实现到我的应用程序的帮助。

我正在尝试制作一个可以捕获颜色的Android应用程序，但我只发现如何获取十六进制值，但我真的需要颜色的名称!请帮忙，某人!下面是整个代码，但它说的是

public static String makeHexString(int value) {
return "#" + Integer.toHexString(value).substring(2);}

这里的这一行，Integer.toHexString 如何才能获取颜色名称而不是十六进制值？

 public class ColorItem implements Parcelable {

    protected final long mId;

    protected int mColor;

    protected String mName;

    protected final long mCreationTime;

    protected transient String mHexString;

    protected transient String mRgbString;

    protected transient String mHsvString;

    public ColorItem(long id, int color) {
        mId = id;
        mColor = color;
        mCreationTime = System.currentTimeMillis();
    }

    private ColorItem(Parcel in) {
        this.mId = in.readLong();
        this.mColor = in.readInt();
        this.mCreationTime = in.readLong();
        this.mName = in.readString();
    }

    public ColorItem(int color) {
        mId = mCreationTime = System.currentTimeMillis();
        mColor = color;
    }

    public long getId() {
        return mId;
    }

    public int getColor() {
        return mColor;
    }

    public void setColor(int color) {
        if (mColor != color) {
            mColor = color;
            mHexString = makeHexString(mColor);
            mRgbString = makeRgbString(mColor);
            mHsvString = makeHsvString(mColor);
        }
    }

    public long getCreationTime() {
        return mCreationTime;
    }

    public String getHexString() {
        if (mHexString == null) {
            mHexString = makeHexString(mColor);
        }
        return mHexString;
    }

    public String getRgbString() {
        if (mRgbString == null) {
            mRgbString = makeRgbString(mColor);
        }
        return mRgbString;
    }

    public String getHsvString() {
        if (mHsvString == null) {
            mHsvString = makeHsvString(mColor);
        }
        return mHsvString;
    }

    public String getName() {
        return mName;
    }

    public void setName(String name) {
        mName = name;
    }

    public static String makeHexString(int value) {
        return "#" + Integer.toHexString(value).substring(2);
    }

    public static String makeRgbString(int value) {
        return "rgb(" + Color.red(value) + ", " + Color.green(value) + ", " + Color.blue(value) + ")";
    }

    public static String makeHsvString(int value) {
        float[] hsv = new float[3];
        Color.colorToHSV(value, hsv);
        return "hsv(" + (int) hsv[0] + "°, " + (int) (hsv[1] * 100) + "%, " + (int) (hsv[2] * 100) + "%)";
    }


    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeLong(this.mId);
        dest.writeInt(this.mColor);
        dest.writeLong(this.mCreationTime);
        dest.writeString(this.mName);
    }

    public static final Creator<ColorItem> CREATOR = new Creator<ColorItem>() {
        public ColorItem createFromParcel(Parcel source) {
            return new ColorItem(source);
        }

        public ColorItem[] newArray(int size) {
            return new ColorItem[size];
        }
    };
}

以下是一些颜色名称:

public String getColorName(String hexColor) {
    String name = "";
    switch (hexColor.toLowerCase()) {
        case "#ff0000":
            name = "Red";
            break;
        case "#00ff00":
            name = "Green";
            break;
        case "#0000ff":
            name = "Blue";
            break;
        case "#ffffff":
            name = "White";
            break;
        case "#000000":
            name = "Black";
            break;
        default:
            name = "Unknown";
        break;
    }
    return name;
}
