[Android][Kotlin] Activity, Fragment by viewModels() 사용 및 종속성

1. build.gradle 종속성 추가

dependencies {
    ...
    // activityViewmodels
    implementation 'androidx.activity:activity-ktx:1.9.0'
    implementation 'androidx.fragment:fragment-ktx:1.6.2'
}

 

 

2. Activity, Fragment 에서 사용

class MainActivity: BaseActivity<ActivityMainBinding>({ ActivityMainBinding.inflate(it) }) {
    private val vm: MainViewModel by viewModels() // viewmodel

    override fun onCreate(savedInstanceState: Bundle?) {
        ...
    }
}
