如何在不刷新活动的情况下更新Kotlin中的Room数据库？

class MyViewModel(application: Application) : AndroidViewModel(application) {
    private val myDao: MyDao = MyDatabase.getDatabase(application).myDao()
    val myData: LiveData<List<MyEntity>> = myDao.getAllData()
}

class MyActivity : AppCompatActivity() {
    private lateinit var myViewModel: MyViewModel

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_my)

        myViewModel = ViewModelProvider(this).get(MyViewModel::class.java)
        myViewModel.myData.observe(this, Observer { data ->
            // 数据库数据更新后的操作
            // 可以在这里更新UI或执行其他逻辑
        })
    }
}

class MyViewModel(application: Application) : AndroidViewModel(application) {
    private val myDao: MyDao = MyDatabase.getDatabase(application).myDao()
    val myData: LiveData<List<MyEntity>> = myDao.getAllData()

    fun insertData(myEntity: MyEntity) {
        viewModelScope.launch(Dispatchers.IO) {
            myDao.insert(myEntity)
        }
    }
}

myViewModel.insertData(myEntity)
