Android 合成 colored颜色 的GSON反序列化

同样，为Colors级定义TypeAdapter(或JsonDeserializer)似乎也起到了作用.例如，这是可行的:

package org.example
import androidx.compose.ui.graphics.Color
import com.google.gson.GsonBuilder
import com.google.gson.JsonDeserializationContext
import com.google.gson.JsonDeserializer
import com.google.gson.JsonElement
import java.lang.reflect.Type

data class Colors(val color: Color)

fun main() {

    val colors = GsonBuilder()
        .registerTypeAdapter(Colors::class.java, ColorsAdapter())
        .registerTypeAdapter(Color::class.java, ColorAdapter())
        .create()
        .fromJson("{color: \"#FFFFFF\"}", Colors::class.java)

    println(colors)
}

class ColorsAdapter : JsonDeserializer<Colors> {
    override fun deserialize(json: JsonElement, typeOfT: Type, context: JsonDeserializationContext): Colors {
        return Colors(context.deserialize(json.asJsonObject.get("color"), Color::class.java))
    }
}

class ColorAdapter : JsonDeserializer<Color> {
    override fun deserialize(json: JsonElement, typeOfT: Type, context: JsonDeserializationContext): Color {
        return Color(json.asString.removePrefix("#").toInt(16))
    }
}
