在jetpack 撰写中如何调整文本大小以使其适合一行

Question

我正在做我的第一个jetpack撰写项目，在标题屏幕和其他一些部分中，我希望有由一个单词组成并且比通常文本更大的“标题”文本。当我在模拟器上测试它们时，一切都很好，但是当我尝试在物理设备上测试时，最后几个字符出现在下一行中，因为它们不适合。所以我的问题是，如何调整文本大小，使其适合每台设备上的一行。

这是我的排版：

val Typography = Typography(
    headlineMedium = TextStyle(
        fontFamily = customFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 36.sp,
        lineHeight = 36.sp,
        letterSpacing = 1.sp
    ),
    labelLarge = TextStyle(
        fontFamily = customFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 32.sp,
        lineHeight = 32.sp,
        letterSpacing = 0.5.sp
    ),
    labelMedium = TextStyle(
        fontFamily = customFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 28.sp,
        lineHeight = 28.sp,
        letterSpacing = 0.5.sp
    ),
    labelSmall = TextStyle(
        fontFamily = customFontFamily,
        fontWeight = FontWeight.Medium,
        fontSize = 24.sp,
        lineHeight = 24.sp,
        letterSpacing = 0.5.sp
    ),
    titleMedium = TextStyle(
        fontFamily = stylizedCustomFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 36.sp,
        lineHeight = 50.sp,
        letterSpacing = 6.sp
    ),
    titleSmall = TextStyle(
        fontFamily = stylizedCustomFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 32.sp,
        lineHeight = 40.sp,
        letterSpacing = 4.sp
    ),
    titleLarge = TextStyle(
        fontFamily = stylizedCustomFontFamily,
        fontWeight = FontWeight.Normal,
        fontSize = 40.sp,
        lineHeight = 60.sp,
        letterSpacing = 8.sp
    ), )

使用 BoxWithConstraints 调整字体大小并获取屏幕大小限制。为了测量目的，您可以使用 TextMeasurer 或 onTextLayout 回调来确定您的文本是否适合可用宽度，并设置最小字体大小以避免文本变得不可读。
