android - 在 Jetpack Compose @Preview 中使用 moshi 时出现渲染问题

问题描述

我正在尝试使用Jetpack Compose 的 @Preview 块中的Moshi将假 JSON 字符串解析为 Object，下面是我的代码：

@Preview("Post Card")
@Composable
fun PostCardPreview() {

    val moshi = Moshi.Builder().build()
    val type: Type =
        Types.newParameterizedType(List::class.java, Post::class.java)
    val jsonAdapter = moshi.adapter<List<Post>>(type)
    val posts = jsonAdapter.fromJson(fakePostDatas) ?: listOf()

    TestAppTheme {
        Surface {
            PostCard(post = posts[0])
        }
    }
}

我遇到了以下问题：

java.lang.NoSuchMethodError: 'com.squareup.moshi.JsonAdapter com.squareup.moshi.Moshi.adapter(java.lang.reflect.Type, java.util.Set, java.lang.String)'

我是 Jetpack Compose 的新手，我是否以错误的方式使用它？还是只是不能在@Preview 中使用 codegen 类？
