Android开发分享一个带圆角的ConstraintLayout的自定义控件

RoundConstraintLayout

直接上代码：

class RoundConstraintLayout  (mContext: Context, attrs: AttributeSet) : ConstraintLayout(mContext,attrs){

    private var radiusRound:Int
    private var topLeftRadius:Int
    private var topRightRadius:Int
    private var bottomLeftRadius:Int
    private var bottomRightRadius:Int
    private var strokeLineWidth:Int
    private var strokeLineColor:Int
    private var backgroundColor = mutableListOf<Int>()

    init {
        mContext.obtainStyledAttributes(attrs, R.styleable.RoundConstraintLayout).apply {
            radiusRound = getDimensionPixelSize(R.styleable.RoundConstraintLayout_radiusRound, 0)
            topLeftRadius = getDimensionPixelSize(R.styleable.RoundConstraintLayout_topLeftRadius, 0)
            topRightRadius = getDimensionPixelSize(R.styleable.RoundConstraintLayout_topRightRadius, 0)
            bottomLeftRadius = getDimensionPixelSize(R.styleable.RoundConstraintLayout_bottomLeftRadius, 0)
            bottomRightRadius = getDimensionPixelSize(R.styleable.RoundConstraintLayout_bottomRightRadius, 0)
            strokeLineWidth = getDimensionPixelSize(R.styleable.RoundConstraintLayout_strokeLineWidth, 0)
            strokeLineColor = getColor(R.styleable.RoundConstraintLayout_strokeLineColor, 0)
            backgroundColor.add(getColor(R.styleable.RoundConstraintLayout_bgColor, mContext.getColors(R.color.c_f6)))
            getColor(R.styleable.RoundConstraintLayout_bgColorCenter, 0).let { if(it != 0) backgroundColor.add(it) }
            getColor(R.styleable.RoundConstraintLayout_bgColorEnd, 0).let { if(it != 0) backgroundColor.add(it) }
        }.recycle()
        if(radiusRound != 0){
            topLeftRadius = radiusRound
            topRightRadius = radiusRound
            bottomRightRadius = radiusRound
            bottomLeftRadius = radiusRound
        }
        setStyle()
    }

    private fun setStyle(orientation: GradientDrawable.Orientation = GradientDrawable.Orientation.LEFT_RIGHT){
        BaseShapeUtils.setShape(
            this,
            backgroundColor.toIntArray(),
            orientation = orientation,
            corner = floatArrayOf(
                topLeftRadius.toFloat(), topLeftRadius.toFloat(),
                topRightRadius.toFloat(),topRightRadius.toFloat(),
                bottomRightRadius.toFloat(),bottomRightRadius.toFloat(),
                bottomLeftRadius.toFloat(),bottomLeftRadius.toFloat()
            ),
            strokeWidth = strokeLineWidth,strokeColor = strokeLineColor
        )
    }

    fun setShape(
        bgColor:MutableList<Int>? = null,
        radiusRound:Int? = null,
        tlRadius:Int? = null,
        trRadius:Int? = null,
        brRadius:Int? = null,
        blRadius:Int? = null,
        lineWide:Int? = null,
        lineColor:Int? = null,
        orientation: GradientDrawable.Orientation = GradientDrawable.Orientation.LEFT_RIGHT
    ){
        bgColor?.let {
            backgroundColor.clear()
            backgroundColor.addAll(it)
        }
        radiusRound?.let {
            topLeftRadius = it
            topRightRadius = it
            bottomRightRadius = it
            bottomLeftRadius = it
        }
        tlRadius?.let { topLeftRadius = it }
        trRadius?.let { topRightRadius = it }
        brRadius?.let { bottomRightRadius = it }
        blRadius?.let { bottomLeftRadius = it }
        lineWide?.let { strokeLineWidth = it }
        lineColor?.let { strokeLineColor = it }
        setStyle(orientation)
    }
}

定义圆角的ConstraintLayout，可以少写很多shape

有需要完整源码的，可以私信我，我每天都看私信的
