可绘制资源¶

设置单色背景¶

调用 setSingle 将 GradientDrawable 设置为单色。

getBinding().btn.background = GradientDrawable().apply {
    shape = RECTANGLE
    cornerRadius = 20f.DP
    setSingle(Color.argb(255,2,218,197))
}

设置圆角¶

Version 0.5.3

调用 setCornerRadii 单独设置 GradientDrawable 的四个圆角。

// 设置四个圆角，半径均为50.0
getBinding().btn.background = GradientDrawable().apply {
    shape = RECTANGLE
    setSingle(Color.BLACK)
    cornerRadius = 50f
}

// 设置四个大小不同的圆角
getBinding().btn.background = GradientDrawable().apply {
    shape = RECTANGLE
    setSingle(Color.BLACK)
    setCornerRadii(0f, 0f, 50f, 50f)
}

设置渐变¶

Version 0.5.3

setGradient 目前支持两种渐变颜色形式。

startColor->endColor
startColor->centerColor->endColor

// startColor->centerColor->endColor
getBinding().btn.background = GradientDrawable().apply {
    shape = RECTANGLE
    cornerRadius = 50f
    setGradient(
        45,
        colorHex2Int("#12c2e9"),
        colorHex2Int("#c471ed"),
        colorHex2Int("#f64f59")
    )
}

// startColor->endColor
getBinding().btn.background = GradientDrawable().apply {
    shape = RECTANGLE
    cornerRadius = 50f
    setGradient(
        45,
        colorHex2Int("#0F2027"),
        colorHex2Int("#78ffd6")
    )
}
