你需要在代码中添加以下代码，然后重新启动Android Studio，就可以在运行时检查数据库了。

    androidx.appcompat.app.AppCompatActivity
    import android.os.Bundle    
    import androidx.room.Room
    import androidx.room.RoomDatabase

    ...

    //创建数据库实例
    val db = Room.databaseBuilder(
        applicationContext,
        MyDatabase::class.java, "database-name"
    ).build()

    //在这里添加代码以启用数据库检查器
    if (BuildConfig.DEBUG) {
        val db = Room.databaseBuilder(
                applicationContext,
                MyDatabase::class.java, "database-name"
            )
            .allowMainThreadQueries()
            .build()
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val builder = AndroidSqliteDriver.Companion.inMemoryDatabaseBuilder(
                InstrumentationRegistry.getInstrumentation().context,
                MyDatabase.Schema
            )
            val driver = builder.build()
            val database = MyDatabase(driver)
        } else {
            val driver = AndroidSqliteDriver(dbHelper)
            val database = MyDatabase(driver)
        }
        Stetho.initializeWithDefaults(this)
        val initializerBuilder = Stetho.newInitializerBuilder(this)

        initializerBuilder.enableWebKitInspector(
                Stetho.defaultInspectorModulesProvider(this)
        )


        initializerBuilder.enableDumpapp(
                Stetho.defaultDumperPluginsProvider(this)
        )

        initializerBuilder.enableWebKitInspector(
                Stetho.defaultInspectorModulesProvider(this)
        )

        initializerBuilder.build()
    }

    //定义数据库实体
    @Entity
    data class User(
        @PrimaryKey val uid: Int,
        @ColumnInfo(name = "first_name") val firstName: String?,
        @ColumnInfo(name = "last_name") val lastName: String?
    )

    //定义数据库访问对象
    @Dao
    interface UserDao {
        @Query("SELECT * FROM user")
        fun getAll(): List
    
        @Query("SELECT * FROM user WHERE uid IN (:userIds)")
        fun loadAllByIds(userIds: IntArray): List
    
        @Query("SELECT * FROM user WHERE first_name LIKE :first AND " +
               "last_name LIKE :last LIMIT 1")
        fun findByName(first: String, last: String): User
    
        @Insert
        fun insertAll(vararg users: User)
}

    //定义数据库
    @Database(entities = [User::class], version = 1)
    abstract class MyDatabase : RoomDatabase() {
        abstract fun userDao(): UserDao
    
        companion object {
            @Volatile
            private var INSTANCE: MyDatabase? = null
    
            fun getDatabase(context: Context): MyDatabase {
                val tempInstance = INSTANCE
                if (tempInstance != null)
