llegalArgumentException：在导航图中找不到与请求 NavDeepLinkRequest-geoMarkerScreen 匹配的导航目的地

Question

我在我的应用程序中使用 jetpack 撰写导航，但在尝试从 homeScreen 导航到 geoMarkerScreen 时出现 IllegalArgumentException。问题出现在 BottomNavigationBar...我该如何解决这个问题？我已经设置了 NavHost

package com.example.bettehomes.navigation


    import androidx.compose.material3.NavigationBar
    import androidx.compose.material3.NavigationBarItem
    import androidx.compose.material3.Icon
    import androidx.compose.material3.Text
    import androidx.compose.runtime.Composable
    import androidx.compose.runtime.getValue
    import androidx.navigation.NavController
    import androidx.navigation.compose.currentBackStackEntryAsState
    
    
    @Composable
    fun BottomNavigationBar(navController: NavController) {
        NavigationBar {
            val navBackStackEntry by navController.currentBackStackEntryAsState()
            val currentRoute = navBackStackEntry?.destination?.route
    
            BottomNavItem.values().forEach { item ->
                NavigationBarItem(selected = currentRoute == item.route,
                    onClick = {
                        navController.navigate(item.route) {
                            popUpTo(navController.graph.startDestinationId) {
                                saveState = true
                            }
                            launchSingleTop = true
                            restoreState = true
                        }
                    }, icon = { Icon(item.icon, contentDescription = null) },label = { Text(item.label) })
                        }
        }

} 

错误似乎位于：

com.example.bettehomes.navigation.BottomNavigationBarKt$BottomNavigationBar$1$1$1.invoke(BottomNavigationBar.kt:23)
                                                                                                        at com.example.bettehomes.navigation.BottomNavigationBarKt$BottomNavigationBar$1$1$1.invoke(BottomNavigationBar.kt:21)

Answer 1

您只能使用

NavHost

构建器功能导航到您在

composable

中定义的目的地。您定义了一个

Screens.GeoMarkerScreen

路线，因此如果您想导航到该屏幕，

item.route

中的

navController.navigate(item.route)

必须与

Screens.GeoMarkerScreen

包含的内容完全相同。

由于您的问题没有告诉我们

item

是什么或它的

route

属性包含什么，我只能从抛出的异常中推断出它 not 包含有效的导航路线。您可以通过在该行设置断点并将

item.route

的实际内容与

Screens.GeoMarkerScreen

进行比较来轻松验证这一点。
