A gradient color picker

Usage

1. Gradle dependency:

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

   val version =

   dependencies {
    implementation 'com.github.wangpeiyuan:GradientColorPickerBar:$version'
   }
   

2. xml:

   <com.yuan.gradientcolorpickerbar.GradientColorPickerBar
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       app:barHeight="20dp"
       app:barRadius="22dp"
       app:colorEntries="@array/colors"
       app:orientation="horizontal"
       app:progress="0.5"
       app:thumbRadius="20dp"
       app:thumbSize="40dp"
       app:thumbStrokeColor="@android:color/white"
       app:thumbStrokeWidth="2dp" />
   

3. Kotlin：

   colorPickerBar.setOnChangeListener(object :
            GradientColorPickerBar.OnChangeListener {
   
            override fun onStartTrackingTouch(gradientColorPickBar: GradientColorPickerBar) {
                super.onStartTrackingTouch(gradientColorPickBar)
            }
   
            override fun onProgressChanged(
                gradientColorPickBar: GradientColorPickerBar,
                progress: Float,
                color: Int,
                fromUser: Boolean
            ) {
                //color
            }
   
            override fun onStopTrackingTouch(gradientColorPickBar: GradientColorPickerBar) {
                super.onStopTrackingTouch(gradientColorPickBar)
            }
        })
   

4. API：

   //The colors to be distributed along the gradient line
   colorPickerBar.setColors(colors: IntArray)
   //
   colorPickerBar.setProgress(@FloatRange(from = 0.0, to = 1.0) progress: Float)
   //Layout be a column or a row
   colorPickerBar.setOrientation(orientation: Int)
   //
   colorPickerBar.setThumbStyle(thumbSize: Float,  thumbRadius: Float, @ColorInt thumbStrokeColor: Int,thumbStrokeWidth: Float)
   //
   colorPickerBar.setBarStyle(barHeight: Float, barRadius: Float)
   //
   colorPickerBar.getOrientation():Int
   //
   colorPickerBar.getProgress():Float
   //
   colorPickerBar.getSelectedColor():Int
   //
   colorPickerBar.setOnChangeListener(onChangeListener: OnChangeListener?)
