Jetpack Compose - 无法更改 Material 3 中的默认字体

Question

In Material 2, the default font can be changed by overriding the defaultFontFamily property

Material 2 Compose

val Typography2 = Typography(
    defaultFontFamily = MyFont
)

But after upgrading to Material 3 it is not possible because there is no defaultFontFamily property

Is there an alternative solution to apply the font throughout the App?

Answer 1

You can do it like this for example:

In Type.kt

val HindSiliguri = FontFamily(
    Font(R.font.hindsiliguri_light, FontWeight.Light),
    Font(R.font.hindsiliguri_medium, FontWeight.Medium),
    Font(R.font.hindsiliguri_regular, FontWeight.Normal),
    Font(R.font.hindsiliguri_semibold, FontWeight.SemiBold),
    Font(R.font.hindsiliguri_bold, FontWeight.Bold),
)

val Typography = Typography(
    bodyMedium = TextStyle(
        fontFamily = HindSiliguri,
        fontWeight = FontWeight.Normal,
        fontSize = 16.sp
    )
)

In Theme.kt

@Composable
fun MyTheme(
    useDarkTheme: Boolean = isSystemInDarkTheme(),
    content: @Composable() () -> Unit
) {
    val colors = if (!useDarkTheme) {
        LightColors
    } else {
        DarkColors
    }

    MaterialTheme(
        colorScheme = colors,
        typography = Typography,
        content = content
    )
}
