导入中的红色文字导航

Question

我卡在这里，解决不了，努力了好久。

我想在 Wear os Projet 中使用导航，但无法正确导入。

这是我的文件：

/* While this template provides a good starting point for using Wear Compose, you can always
 * take a look at https://github.com/android/wear-os-samples/tree/main/ComposeStarter to find the
 * most up to date changes to the libraries and their usages.

    override fun onCreate(savedInstanceState: Bundle?) {
        installSplashScreen()

        super.onCreate(savedInstanceState)

        setTheme(android.R.style.Theme_DeviceDefault)

        setContent {
            MainScreen()
        }
    }
}


@Composable
fun MainScreen () {
    Box(
        modifier = Modifier
            .fillMaxSize(),
        contentAlignment = Alignment.Center
    ) {

        Column {

            Button(
                onClick = {},
                modifier = Modifier
                    .size(120.dp, 50.dp),
                shape = RoundedCornerShape(8.dp)
            ) { Text("Patinage libre") }

            Spacer(modifier = Modifier.height(16.dp))

            Button(
                onClick = {},
                modifier = Modifier
                    .size(120.dp, 50.dp),
                shape = RoundedCornerShape(8.dp)
            ) { Text("Match") }
        }
    }
}

@Preview(device = WearDevices.LARGE_ROUND, showSystemUi = true)
@Composable
fun  MainScrenPreview() {
    MainScreen()
}

import androidx.navigation.compose.NavHost
import androidx.navigation.compose.rememberNavController

当我将鼠标悬停在导入中的红色导航词上时，它显示：“未解析的引用”

Android Studio 建议我使用 Alt Shift Enter 导入依赖项，我这样做了，但没有成功。

在我的 gradle 中，我确实导入了导航依赖项，如您所见。

implementation(libs.androidx.navigation.compose)

我尝试重新启动计算机，检查更新，但似乎没有任何效果。这是非常令人沮丧的。

如何修复这两个导航导入？

谢谢

下面是我的 gradle：

------------------------------------------------- -------------------------------------------------- ---------

plugins {
    alias(libs.plugins.android.application)
    alias(libs.plugins.kotlin.android)
    alias(libs.plugins.kotlin.compose)
}

android {
    namespace = "com.example.myapplication"
    compileSdk = 34

    defaultConfig {
        applicationId = "com.example.myapplication"
        minSdk = 28
        targetSdk = 34
        versionCode = 1
        versionName = "1.0"

    }

    buildTypes {
        release {
            isMinifyEnabled = false
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
        }
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_11
        targetCompatibility = JavaVersion.VERSION_11
    }
    kotlinOptions {
        jvmTarget = "11"
    }
    buildFeatures {
        compose = true
    }
}

dependencies {

    implementation(libs.play.services.wearable)
    implementation(platform(libs.compose.bom))
    implementation(libs.ui)
    implementation(libs.ui.graphics)
    implementation(libs.ui.tooling.preview)
    implementation(libs.compose.material)
    implementation(libs.compose.foundation)
    implementation(libs.wear.tooling.preview)
    implementation(libs.activity.compose)
    implementation(libs.core.splashscreen)
    androidTestImplementation(platform(libs.compose.bom))
    androidTestImplementation(libs.ui.test.junit4)
    debugImplementation(libs.ui.tooling)
    debugImplementation(libs.ui.test.manifest)
}

确保您的

toml

文件中存在与您的

build.gradle

条目相对应的条目。

implementation(libs.androidx.navigation.compose)

在您的

build.gradle

中应该指向条目

[versions]
//...
navigationCompose = "2.8.5"

[libraries]
//...
androidx-navigation-compose = { module = "androidx.navigation:navigation-compose", version.ref = "navigationCompose" }

在您的

libs.versions.toml

文件中。
