活动中的视图绑定与膨胀和根有一些问题

Question

I have issues with view binding in android studio with inflate and root. below of inflate and root is a redline.

I also write view binding modules in build.gradle. This is my build.gradle codes.

defaultConfig {
    applicationId "com.wallpaper.view"
    minSdk 21
    targetSdk 32
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
    jvmTarget = '1.8'
}
buildFeatures {
    viewBinding = true
}

dependencies {

implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.appcompat:appcompat:1.5.1'
implementation 'com.google.android.material:material:1.7.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.4'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.0'

And this is my activity codes.

class MainActivity : AppCompatActivity() {

    lateinit var binding:ActivityMainBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)
    }
}

I have a read line below inflate and root.

How can I fix this?

Answer 1

I realize some of the modules in my build.gradle was not updated, Then I updated modules and issue or red line below of inflate, and root was gone. There are the codes I updated.

from this

android {
namespace 'com.wallpaper.view'
compileSdk 32

defaultConfig {
    applicationId "com.wallpaper.view"
    minSdk 21
    targetSdk 32
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

To this

android {
namespace 'com.wallpaper.view'
compileSdk 33

defaultConfig {
    applicationId "com.wallpaper.view"
    minSdk 21
    targetSdk 33
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

I just update the version of compileSdk and targetSdk.
