Jetpack Compose中TextField获焦后点击不弹出键盘问题求助

开发基于Jetpack Compose的Android应用时，所有TextField组件均存在以下异常：

• 首次点击TextField，键盘正常弹出
• 按返回键隐藏键盘后，再次点击该TextField，键盘无法弹出
• 仅当先点击其他TextField，再切回原TextField时，键盘才会正常弹出

对应的TextField实现代码：

fun NameViewer(nameState: MutableState<String>) {

    Row(verticalAlignment = Alignment.CenterVertically, modifier = Modifier.padding(bottom = 8.dp)) {
        Text(text = "Item Name:", modifier = Modifier.width(104.dp))
        TextField(
            value = nameState.value,
            onValueChange = { if (it.length <= 15) nameState.value = it },
            placeholder = { Text("Enter name") },
            modifier = Modifier.weight(1f),
            singleLine = true
        )
    }
}

经测试确认问题源于依赖兼容性冲突，当前Gradle配置如下：

模块级Gradle配置 #

plugins {
    id("com.android.application")
    id("org.jetbrains.kotlin.android")
    id("com.google.devtools.ksp")
}

android {
    namespace = "com.example.wastesamaritanassignment1"
    compileSdk = 34

    defaultConfig {
        applicationId = "com.example.wastesamaritanassignment1"
        minSdk = 24
        targetSdk = 34
        versionCode = 1
        versionName = "1.0"

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
        vectorDrawables {
            useSupportLibrary = true
        }
    }

    buildTypes {
        release {
            isMinifyEnabled = true
            isShrinkResources = true
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
        }
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
    kotlinOptions {
        jvmTarget = "17"
    }
    buildFeatures {
        compose = true
        buildConfig = true
    }
    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.4"
    }
    packaging {
        resources {
            excludes += "/META-INF/{AL2.0,LGPL2.1}"
        }
    }
}

dependencies {
    implementation(platform("androidx.compose:compose-bom:2023.10.01"))
    androidTestImplementation(platform("androidx.compose:compose-bom:2023.10.01"))

    val roomVersion = "2.6.1"
    implementation("androidx.room:room-runtime:$roomVersion")
    annotationProcessor("androidx.room:room-compiler:$roomVersion")
    ksp("androidx.room:room-compiler:$roomVersion")
    implementation("androidx.room:room-ktx:$roomVersion")
    implementation("androidx.room:room-paging:$roomVersion")

    implementation("io.coil-kt:coil-compose:2.5.0")

    implementation("androidx.core:core-ktx:1.12.0")
    implementation("androidx.lifecycle:lifecycle-runtime-ktx:2.6.2")

    implementation("androidx.lifecycle:lifecycle-livedata-ktx:2.6.2")
    implementation("androidx.compose.runtime:runtime-livedata:1.5.4")

    implementation("androidx.paging:paging-compose:3.2.1")

    implementation("androidx.activity:activity-compose:1.8.2")
    implementation(platform("androidx.compose:compose-bom:2023.10.01"))
    implementation("androidx.compose.ui:ui")
    implementation("androidx.compose.ui:ui-graphics")
    implementation("androidx.compose.ui:ui-tooling-preview")
    implementation("androidx.compose.material3:material3:1.2.0-beta01")

    testImplementation("junit:junit:4.13.2")
    androidTestImplementation("androidx.test.ext:junit:1.1.5")
    androidTestImplementation("androidx.test.espresso:espresso-core:3.5.1")
    androidTestImplementation(platform("androidx.compose:compose-bom:2023.10.01"))
    androidTestImplementation("androidx.compose.ui:ui-test-junit4")
    debugImplementation("androidx.compose.ui:ui-tooling")
    debugImplementation("androidx.compose.ui:ui-test-manifest")
}

顶层Gradle配置 #

// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id("com.android.application") version "8.2.0" apply false
    id("org.jetbrains.kotlin.android") version "1.9.20" apply false
    id("com.google.devtools.ksp") version "1.9.20-1.0.13" apply false
}

该问题由Jetpack Compose相关依赖版本不兼容导致，可通过以下步骤修复：

1. 升级Compose BOM到稳定版
   将模块级Gradle中的Compose BOM版本从2023.10.01升级至最新稳定版（示例使用2024.06.00），确保所有Compose库版本统一兼容。

2. 匹配Kotlin与Compose Compiler版本
   当前Kotlin版本为1.9.20，对应的Compose Compiler版本应为1.5.11，更新composeOptions中的版本号。

3. 升级Activity Compose依赖
   将androidx.activity:activity-compose升级至与Compose BOM兼容的版本（示例使用1.9.0）。

4. 统一Material3版本管理
   移除Material3依赖的手动版本号，由Compose BOM自动管理，避免版本冲突。

修改后的关键配置片段：

// 模块级Gradle - composeOptions调整
composeOptions {
    kotlinCompilerExtensionVersion = "1.5.11"
}

// 模块级Gradle - dependencies调整
dependencies {
    // 升级Compose BOM
    implementation(platform("androidx.compose:compose-bom:2024.06.00"))
    androidTestImplementation(platform("androidx.compose:compose-bom:2024.06.00"))

    // 升级activity-compose
    implementation("androidx.activity:activity-compose:1.9.0")
    
    // 由BOM管理Material3版本
    implementation("androidx.compose.material3:material3")
    
    // 其他依赖保持不变
}

5. 同步并清理构建
   执行File -> Sync Project with Gradle Files同步配置，再通过Build -> Clean Project清理缓存，重新编译运行即可解决键盘不弹出问题。
