EColorPicker

一个Android颜色选择套件，具体效果见下图。

依赖配置

项目 build.gradle

allprojects {
    repositories {
        ...
        maven { url 'https://www.jitpack.io' }
        }
}

模块 build.gradle

dependencies {
    implementation 'com.github.RickyHal:EColorPicker:$latest_version'
}

使用方式

颜色选择器

<com.ricky.color_picker.ui.ColorWheelPickerView
    android:id="@+id/color_picker_view"
    android:layout_width="200dp"
    android:layout_height="200dp" />

默认宽高300dp，获取选择的颜色：

binding.colorPickerView.setOnColorSelectedListener(object : OnColorSelectedListener {
    override fun onColorSelecting(color: Int) {
       // 手指触摸中当前的颜色
    }

    override fun onColorSelected(color: Int) {
       // 手指弹起时最后的颜色
    }
})

设置是否显示颜色放大镜以及放大镜半径：

binding.colorPickerView.hasScaleMirror = true
binding.colorPickerView.mirrorRadius = 10.dp

色环选择器

<com.ricky.color_picker.ui.ColorRingPickerView
    android:id="@+id/color_ring_view"
    android:layout_width="200dp"
    android:layout_height="200dp" />

默认宽高300dp，获取选择的颜色：

binding.colorRingPickerView.setOnColorSelectedListener(object : OnColorSelectedListener {
    override fun onColorSelecting(color: Int) {
       // 手指触摸中当前的颜色
    }

    override fun onColorSelected(color: Int) {
       // 手指弹起时最后的颜色
    }
})

设置是否显示颜色放大镜以及放大镜半径：

binding.colorPickerView.hasScaleMirror = true
binding.colorPickerView.mirrorRadius = 10.dp

设置圆环颜色值，从内到外，为一个24*7的16进制颜色字符串二维数组：

binding.colorRingView.setColor(colorList)

默认色环颜色值为：

private String[][] colorArray = {
        {
                "#fef5ce", "#fff3cd", "#feeeca", "#fdeac9", "#fee7c7", "#fce3c4",
                "#fbddc1", "#fad7c3", "#fad0c2", "#f2ced0", "#e6cad9",

                "#567C03", "#718500", "#888D00"
        }
};

设置选中状态时色块的颜色值：

binding.colorRingView.setSelectedBlockColor(Color.WHITE)

深度选择器

<com.ricky.color_picker.ui.ColorSlideView
    android:id="@+id/color_slide_view"
    android:layout_width="match_parent"
    android:layout_height="30dp"
    android:layout_marginHorizontal="20dp"
    android:layout_marginVertical="20dp" />

需要给定宽高，获取当前值

binding.colorRingPickerView.setOnColorSelectedListener(object : OnColorSelectedListener {
    override fun onColorSelecting(color: Int) {
       // 手指触摸中当前的颜色
    }

    override fun onColorSelected(color: Int) {
       // 手指弹起时最后的颜色
    }
})

设置基准颜色：

binding.colorSlideView.setBaseColor(Color.WHITE)

设置当前位置：

binding.colorSlideView.setPosition(0.5f)

透明度选择器

<com.ricky.color_picker.ui.AlphaSlideView
    android:id="@+id/alpha_slide_view"
    android:layout_width="match_parent"
    android:layout_height="30dp"
    android:layout_marginHorizontal="20dp"
    android:layout_marginVertical="20dp" />

同样需要给定宽高，获取当前透明度

binding.alphaSlideView.setOnAlphaSelectedListener(object : OnAlphaSelectedListener {
    override fun onAlphaSelecting(alpha: Float) {
        // 手指触摸中的透明度
    }

    override fun onAlphaSelected(alpha: Float) {
        // 手指弹起时的透明度
    }
})
