用Jetpack Compose解锁你的创意：绘制一只跃动的兔子

兔年伊始，正是释放创意，迎接机遇的时刻。如果你也向往参与「兔了个兔」创意投稿大赛，不妨借助谷歌推出的强大Android UI工具包——Jetpack Compose，用代码绘出别具一格的兔子画，让你的创意一鸣惊人！

Jetpack Compose的魅力：声明式编程，高效性能，简洁代码

Jetpack Compose与传统Android UI框架相比，有着独特的优势。它的声明式编程方式，让你只需UI的最终状态，系统就会自动生成对应的界面元素，大幅简化了开发过程。同时，它的高效性能和简洁代码，让你能快速、高效地构建出美观且响应式用户界面。

绘制一只灵动兔子的七大步骤

现在，让我们用Jetpack Compose，一步步绘制一只跃动的兔子：

1. 绘制兔子头部

Canvas(modifier = Modifier.fillMaxSize()) {
    drawCircle(
        color = Color.White,
        radius = 100f,
        center = Offset(200f, 200f)
    )
}

2. 添加兔子耳朵

Path().apply {
    moveTo(200f, 100f)
    lineTo(250f, 150f)
    lineTo(200f, 200f)
    close()
}
.let { path ->
    drawPath(
        path = path,
        color = Color.White
    )
}

3. 绘制兔子眼睛

drawCircle(
    color = Color.Black,
    radius = 10f,
    center = Offset(180f, 180f)
)

drawCircle(
    color = Color.Black,
    radius = 10f,
    center = Offset(220f, 180f)
)

4. 绘制兔子嘴巴

Path().apply {
    moveTo(170f, 220f)
    lineTo(230f, 220f)
    quadTo(250f, 240f, 230f, 260f)
    lineTo(170f, 260f)
    quadTo(150f, 240f, 170f, 220f)
    close()
}
.let { path ->
    drawPath(
        path = path,
        color = Color.Black
    )
}

5. 添加兔子胡须

drawLine(
    color = Color.Black,
    start = Offset(170f, 240f),
    end = Offset(150f, 270f),
    strokeWidth = 5f
)

drawLine(
    color = Color.Black,
    start = Offset(230f, 240f),
    end = Offset(250f, 270f),
    strokeWidth = 5f
)

6. 绘制兔子身体

drawRoundRect(
    color = Color.White,
    cornerRadius = 50f,
    size = Size(200f, 100f),
    topLeft = Offset(150f, 300f)
)

7. 添加兔子四肢

drawLine(
    color = Color.Black,
    start = Offset(170f, 400f),
    end = Offset(150f, 450f),
    strokeWidth = 5f
)

drawLine(
    color = Color.Black,
    start = Offset(230f, 400f),
    end = Offset(250f, 450f),
    strokeWidth = 5f
)

drawLine(
    color = Color.Black,
    start = Offset(150f, 450f),
    end = Offset(250f, 450f),
    strokeWidth = 5f
)
