#### 安装教程

1.在项目根目录下的build.gradle文件中，
```
allprojects {
   repositories {
       maven {
           url 'https://s01.oss.sonatype.org/content/repositories/releases/'
       }
   }
}
```
2.在entry模块的build.gradle文件中，
```
dependencies {
   implementation('com.gitee.chinasoft_ohos:Colorpicker_library:1.0.0')
   ......  
}
```
在sdk6，DevEco Studio2.2 Beta1下项目可直接运行 如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件， 并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

#### 使用说明

Demo中调用library组件，然后通过五个功能操作展示组件。 

1、布局文件中引用自定义选择器界面效果：
```xml
<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    xmlns:app="http://schemas.huawei.com/apk/res-auto"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:background_element="#333333"
    ohos:orientation="vertical">

    <DirectionalLayout
        ohos:height="match_content"
        ohos:width="match_content"
        ohos:alignment="center"
        ohos:orientation="vertical">

        <com.flask.colorpicker.ColorPickerView
            ohos:id="$+id:colorpicker"
            ohos:width="match_content"
            ohos:height="400vp"
            ohos:layout_alignment="vertical_center"
            app:type="0"
            app:density="12"
            />

        <DependentLayout
            ohos:height="match_parent"
            ohos:width="match_parent"
            ohos:left_margin="10vp"
            ohos:right_margin="10vp"
            ohos:weight="1"
            >

            <com.flask.colorpicker.slider.LightnessSlider
                ohos:id="$+id:v_lightness_slider2"
                ohos:width="match_parent"
                ohos:top_margin="8vp"
                ohos:alignment="center"
                ohos:right_margin="5vp"
                ohos:height="20vp"
                />
            <Slider
                ohos:id="$+id:v_ligheness_touch"
                ohos:height="20vp"
                ohos:progress="100"
                ohos:width="match_parent"
                ohos:align_parent_start="true"
                app:layout_constraintStart_toStartOf="parent"
                ohos:progress_color="#00FF2797"
                ohos:bottom_margin="-10vp"
                ohos:background_instruct_element="#00ffffff"
                ohos:weight="1"/>

        </DependentLayout>

        <DependentLayout
            ohos:height="match_parent"
            ohos:width="match_parent"
            ohos:left_margin="10vp"
            ohos:right_margin="10vp"
            ohos:top_margin="10vp"
            ohos:weight="1"
            >

            <com.flask.colorpicker.slider.AlphaSlider
                ohos:id="$+id:v_alpha_slider2"
                ohos:width="match_parent"
                ohos:alignment="center"
                ohos:top_margin="8vp"
                ohos:right_margin="5vp"
                ohos:height="20vp"
                />
            <Slider
                ohos:id="$+id:v_alpha_touch"
                ohos:height="20vp"
                ohos:progress="100"
                ohos:width="match_parent"
                ohos:align_parent_start="true"
                app:layout_constraintStart_toStartOf="parent"
                ohos:progress_color="#00FF2797"
                ohos:bottom_margin="-10vp"
                ohos:background_instruct_element="#00ffffff"
                ohos:weight="1"/>

        </DependentLayout>

    </DirectionalLayout>

</DirectionalLayout>
```

其中 自定义颜色选择器 是ColorPickerView类：

```xml
<com.flask.colorpicker.ColorPickerView
    ohos:id="$+id:colorpicker"
    ohos:width="match_content"
    ohos:height="400vp"
    ohos:layout_alignment="vertical_center"
    app:type="0"
    app:density="12"
    />

```

可以通过添加设置透明度和亮度。

```xml
<com.flask.colorpicker.slider.LightnessSlider
    ohos:id="$+id:v_lightness_slider2"
    ohos:width="match_parent"
    ohos:top_margin="8vp"
    ohos:alignment="center"
    ohos:right_margin="5vp"
    ohos:height="20vp"
    />
<com.flask.colorpicker.slider.AlphaSlider
    ohos:id="$+id:v_alpha_slider2"
    ohos:width="match_parent"
    ohos:alignment="center"
    ohos:top_margin="8vp"
    ohos:right_margin="5vp"
    ohos:height="20vp"
    />
```
2、在ability中增加自定义颜色选择器的 回调，用于接收选择的颜色值
```java
  colorPickerView = (ColorPickerView) findComponentById(ResourceTable.Id_colorpicker);
    colorPickerView.addOnColorSelectedListener(new OnColorSelectedListener() {
        @Override
        public void onColorSelected(int selectedColor) {
            // selectedColor 为选择的颜色值
            alphaSlider.setColor(selectedColor);//选择颜色后设置透明度进度条的颜色
            lightnessSlider.setColor(selectedColor);//选择颜色后设置亮度进度条的颜色
        }
    });
  
```
3、滑动透明度和亮度进度条进行改变选择器的颜色变化。
```java

    AlphaSlider alphaSlider = (AlphaSlider) findComponentById(ResourceTable.Id_v_alpha_slider2);
        Slider alphaTouch = (Slider) findComponentById(ResourceTable.Id_v_alpha_touch);
        Slider lightnessTouch = (Slider) findComponentById(ResourceTable.Id_v_ligheness_touch);
        LightnessSlider lightnessSlider = (LightnessSlider) findComponentById(ResourceTable.Id_v_lightness_slider2);
        // 透明度
        alphaTouch.setValueChangedListener(new Slider.ValueChangedListener() {
            @Override
            public void onProgressUpdated(Slider slider, int ii, boolean isB) {
                int value = ii / Constant.TEN;
                float alphaValue = (1.0f / Constant.TENF) * value;
                colorPickerView.updateAlphaValue(alphaValue);
            }

            @Override
            public void onTouchStart(Slider slider) {
            }

            @Override
            public void onTouchEnd(Slider slider) {
            }
        });

        // 亮度
        lightnessTouch.setValueChangedListener(new Slider.ValueChangedListener() {
            @Override
            public void onProgressUpdated(Slider slider, int ii, boolean isB) {
                int value = ii / Constant.TEN;
                float lightessValue = (1.0f / Constant.TENF) * value;
                colorPickerView.updateLightnessValue(lightessValue);
            }

            @Override
            public void onTouchStart(Slider slider) {
            }

            @Override
            public void onTouchEnd(Slider slider) {
            }
        });
```
