项目介绍:

BalloonPicker

控件拆分:

元素 拆分 效果
基线 已选择、未选择 根据触摸块改变长度
触摸块 触摸动画、内外圆 触摸时,内外圆按各自约束匀速放大;结束时,内外圆按各自约束匀速缩小
气球 缩放、位移 触摸前后缩放,移动时,匀速移动,中心旋转
文本 描述、值回调 普通文本、触摸显示回调值

绘制流程拆分

绘制基线和触摸块

分别绘制选中和未选中的基线
然后绘制触摸块外圆和内圆 

为触摸块添加动画

触摸块样式动画

气球动画

通过拆分:
1、ACTION_MOVE,当触摸坐标发生位移,气球旋转对应角度以保持风力阻挡的惯性。气球中心点到基线的垂线,与气球中心点和触点中心点 的直线的夹角,即为当前状态下的旋转角度

        val b = pointF.x - trackLayer?.getPadding()!!
        val angleRoTan = -atan(b/distanceVerticalBetweenBalloonAndTrackLayer) / PI  * 180

        balloon?.rotation = if (angleRoTan.toFloat() > 0F ) 0F else angleRoTan.toFloat()

2、同时以匀速向新的圆点移动,直到气球中心x与触摸点x重合。
大盈彩票开户通过监听将TrackLayer的touch数据传递给pickerView,改造了统一的接口:

interface TrackLayerListener {
   fun layerTouchedDown()
   fun layerTouchedUp()
   fun layerTouchedMoving(value : Long, pointAtLayer : PointF)
}

ZAI layerTouchedMoving() ZHONGCHULIQIQIUDEYIDONGLUOJI.

 override fun layerTouchedMoving(value: Long, pointAtLayer: PointF) {
        pointThumb.set(pointAtLayer.x, height.toFloat() - trackLayer?.getPadding()!!)
        val b = pointThumb.x.toInt() - centerOfBalloon.x.toInt()
        if (abs(b) > distanceVerticalBetweenBalloonAndTrackLayer.toInt()){
            initAnimation(ValueAnimator.ofInt(centerOfBalloon.x.toInt(), pointThumb.x.toInt()))

            val xOfBalloon = (centerOfBalloon.x - balloon?.layoutParams!!.width / 2 + if (b > 0)  b-distanceVerticalBetweenBalloonAndTrackLayer else b + distanceVerticalBetweenBalloonAndTrackLayer).toInt()

            balloon?.layout( xOfBalloon , balloon?.y!!.toInt(), xOfBalloon + balloon?.layoutParams!!.width, balloon?.y!!.toInt() +balloon?.layoutParams!!.height )

            centerOfBalloon.set(xOfBalloon + balloon?.layoutParams!!.width / 2F,  balloon?.y!! + balloon?.layoutParams!!.height / 2)

            rotateBalloon()
        }
        moveBalloon()
    }


效果还可以,接下来就需要根据picker的取值来动态缩放气球,同时维持住气球的底部位置不变
本计划直接调用scale API, 奈何privot也需要动态控制,不然不能维持气球底部垂直位置不变。

 override fun layerTouchedMoving(value: Long, pointAtLayer: PointF) {
            //...
            val valueAtBalloon =trackLayer?.minValue()!! +  (trackLayer?.maxValue()!! - trackLayer?.minValue()!!) *  centerOfBalloon.x/measuredWidth

            val disScaleHeight = balloonHeightDefault * (valueAtBalloon - trackLayer?.minValue()!!) / (trackLayer?.maxValue()!! - trackLayer?.minValue()!!)

            val disScaleWidth = balloonWidthDefault/2 * (valueAtBalloon - trackLayer?.minValue()!!) / (trackLayer?.maxValue()!! - trackLayer?.minValue()!!)

            //...
            balloon?.layout( xOfBalloon  , balloonDefaultY.toInt() - disScaleHeight.toInt(), xOfBalloon + balloonWidthDefault.toInt() + disScaleWidth.toInt() * 2, (balloonDefaultY + balloonHeightDefault).toInt())
            centerOfBalloon.set(xOfBalloon + disScaleWidth + balloonWidthDefault / 2F,  balloonDefaultY + balloonHeightDefault/2 - disScaleHeight/2 )
            //...
        }
        //...
 }

4、气球显示隐藏
气球能动能缩放了,接下来给气球加入出入动画,

override fun layerTouchedDown() {
        balloon?.startAnimation(BalloonAnimSet.create(true, 0F, 0F, pointThumb.y - balloon?.y!!, 0F, context , listenerEnter))
}

override fun layerTouchedUp() {
        balloon?.visibility = View.INVISIBLE
        pointThumb.set(trackLayer?.centerPoint()!!.x, height.toFloat() - trackLayer?.getPadding()!!)

        initAnimation(ValueAnimator.ofInt(centerOfBalloon.x.toInt(), pointThumb.x.toInt()))

        moveBalloon()
        balloon?.startAnimation(BalloonAnimSet.create(false, 0F, 0F, 0F, pointThumb.y - balloon?.y!!, context , listenerExit))
}

LAIKANKANXIAOGUOBA:

开始使用

修饰一下,抛出必要的样式设置方法,最终效果完成:
//使用方法

大盈彩票开户Add it in your root build.gradle at the end of repositories:

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

大盈彩票开户Step 2. Add the dependency

dependencies {
        implementation 'com.github.fairytale110:BalloonPicker:1.0.1'

大盈彩票开户Then, Drop it to XML layout or new it

<tech.nicesky.balloonpicker.BalloonPickerView
        android:id="@+id/balloon_picker"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
 />

大盈彩票开户Finally, custom it's style as you want

fun load(){
     balloon_picker.layerValues(10, 50, 5)

     balloon_picker.defaultValue(30)
     balloon_picker.setColorFoThumb("#FFFFFF".toColorInt(), "#512DA8".toColorInt())
     balloon_picker.setColorForLayer("#512DA8".toColorInt(), "#BDBDBD".toColorInt())
     balloon_picker.setColorForBalloon("#512DA8".toColorInt())
     balloon_picker.setColorForBalloonValue("#FFFFFF".toColorInt())
     balloon_picker.colorOfDesc = "#000000".toColorInt()
     balloon_picker.colorOfValue = "#000000".toColorInt()
     balloon_picker.desc = "Quantity"
     balloon_picker.valueListener = object : BalloonPickerListener{
               override fun changed(value: Long) {
                      Log.w("MainActivity","value: $value")
               }
     }
     // val valueSelected = balloon_picker.getValue()
 }
