IllegalArgumentException：maxHeight473必须> = minHeight747

问题描述

我正在尝试从Jetpack Compose中获得一个示例，并在下面得到此错误，由于此代码之前没有起作用，所以我没有做任何更改，唯一更改的是版本从 dev15 到 alpha-01 ，然后发生了

 java.lang.IllegalArgumentException: maxHeight(473) must be >= minHeight(747)

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            RecipeList(recipeList)
        }
    }
}

@Composable
fun RecipeCard(recipe: Recipe) {
    val image = imageResource(R.drawable.header)
    Column(modifier = Modifier.padding(16.dp)) {
        val imageModifier = Modifier
                .preferredHeightIn(maxHeight = 180.dp)
                .fillMaxWidth()
                .clip(shape = RoundedCornerShape(8.dp))

        Image(image,modifier= imageModifier,contentScale = ContentScale.Crop)
        Spacer(Modifier.preferredHeight(16.dp))
        Text(recipe.title,style = typography.h6)
        for(ingredient in recipe.ingredients){
            Text(ingredient,style = typography.body2)
        }

    }
}

@Composable
fun RecipeList(recipeList:List<Recipe>){
    LazyColumnFor(recipeList) { item ->
        RecipeCard(recipe = item)
    }
}

@Preview(showBackground = true)
@Composable
fun RecipePreview(){
    RecipeList(recipeList)
}

data class Recipe(
        @DrawableRes val imageResource: Int,val title: String,val ingredients: List<String>
)

我认为问题可能出在导入的dp单位中，我真的不知道为什么会发生这种情况

解决方法

已通过替换固定

commit bed4....80d3 (HEAD -> oldbranch)
commit bed4....80d3 (HEAD -> newbranch,oldbranch)

使用

        .preferredHeightIn(maxHeight = 180.dp)
