問題 #1

What do you want from Room when you create a DAO method and annotate it with @Update?
Example:
@Dao
interface MyDao {
@Update
fun updateUsers(vararg users: User)
}

A. Room removes a set of entities, given as parameters, from the database. It uses the primary keys to find the entities to delete.
B. Room modifies a set of entities, given as parameters, in the database. It uses a query that matches against the primary key of each entity.
C. Room generates an implementation that inserts all parameters into the database in a single transaction.

問題 #2

The easiest way of adding menu items (to specify the options menu for an activity) is inflating an XML file into the Menu via MenuInflater. With menu_main.xml we can do it in this way:

A. override fun onOptionsItemSelected(item: MenuItem): Boolean {
menuInflater.inflate(R.menu.menu_main, menu) return super.onOptionsItemSelected(item)
}
B. override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.menu.menu_main)
}
C. override fun onCreateOptionsMenu(menu: Menu): Boolean { menuInflater.inflate(R.menu.menu_main, menu) return true
}

問題 #3

Under the hood WorkManager uses an underlying job dispatching service based on the following criteri a. You need to move services to the correct places.

問題 #4

An example. In our ViewModelFactory (that implements ViewModelProvider.Factory) we have an instance of our Repository, named mRepository. Our ViewModel has such constructor:
class MyViewModel(private val mRepository: MyRepository) : ViewModel() ...
Next, in our ViewModelFactory create ViewModel method (overriden) looks like this:
override fun <T : ViewModel?> create(modelClass: Class<T>): T {
return try {
//MISSED RETURN VALUE HERE"
} catch (e: InstantiationException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: IllegalAccessException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: NoSuchMethodException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: InvocationTargetException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
}
}
What should we write instead of "//MISSED RETURN VALUE HERE"?

A. modelClass.getConstructor(MyRepository::class.java)
.newInstance()
B. modelClass.getConstructor()
.newInstance(mRepository)
C. modelClass.getConstructor(MyRepository::class.java)
.newInstance(mRepository)
