使用匕首柄 + 解析服务器 SDK：java.lang.IllegalArgumentException

Question

目前，我正在做一个项目，我尝试同时使用匕首（刀柄）和 parseServer SDK。问题是在我看来不可能在一个项目中使用这种组合...

以下是我对为什么我认为这是不可能的看法，至少在方式上是这样，并且知道我希望它成为什么样子：

当使用 Parse SDK 并创建一个 class 时，您必须使用 @ParseClasssName("YourDBClassName") 对其进行注释。在调用 Parse.initialize....

之前，必须使用 ParseObject.registerSubclass(YourClassName::class.java) 在 onCreate() 中注册此自定义 class

现在我的问题来了：当使用匕首（刀柄）并创建这个自定义Class时，必须在调用onCreate()之前注入@Inject lateinit var YourClassName。但是当你inject这个customClass在调用onCreate()解析之前抛出一个Error，因为1.它不知道这个class是一个customClass 2. 必须在 onCreate() 方法中创建 ParseObject。

为了更清楚一点，这是我的代码和我想要实现的目标：

自定义用户Class

@ParseClassName("User")
data class User(var name: String, var passWord: String, var eMail: String) : ParseUser() {

    @Inject constructor(): this("","","")

    // Creates a new User
    fun signUpWithOutVerification() = apply {
        username = name
        setPassword(passWord)
        email = eMail
        signUpInBackground()
    }

    // logIn
    fun logIn() = logInInBackground(name, passWord) ?: Timber.e("logIn Error")

    // logOut
    fun logOut() = logOutInBackground() ?: Timber.e("logOut Error")

    // Update
    fun updateCredential(key: String, value: Any) = getCurrentUser().apply {
        put(key, value)
        saveInBackground()
    } ?: Timber.e("Update failed")

    // Delet and Logout
    fun deleteUser() = getCurrentUser().apply {
        deleteInBackground()
        logOut()
    } ?: Timber.e("Delete failed")

应用模块

@Module
@InstallIn(ApplicationComponent::class)
object ApplicationModule {

    @Provides
    @Singleton
    fun provideUser() = User()

}

主要活动

@AndroidEntryPoint
class MainActivity : AppCompatActivity() {

    @Inject lateinit var user: User


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

        ParseObject.registerSubclass(User::class.java)

        Parse.initialize(
            Parse.Configuration.Builder(this)
            .applicationId("YourAppKey")
            .clientKey("YourClientKey")
            .server("https://parseapi.back4app.com")
            .build()
        )

        Timber.plant(Timber.DebugTree())

        lateinit var userName: String
        lateinit var userPw: String

        btn_signup.setOnClickListener {
            userName = etName.text.toString()
            userPw = etPassword.text.toString()
            user.apply{
                name = userName
                passWord = userPw
                eMail = "$userName@email.com"
                signUpWithOutVerification()
            }

        }

主应用程序

@HiltAndroidApp
class App : Application()

请注意！

我以前从未使用过依赖注入
我是匕首新手（刀柄）
我是解析sdk的新手

所以我可能只是不具备编写所需代码的知识。我想做的是，那把匕首（刀柄）创建用户 + 获取他的名字等...

非常感谢您的帮助，谢谢！

Answer 1

您应该将 registerSubclass() 代码移动到您的 application class。

你的applicationclass:

@HiltAndroidApp
class App : Application() {

 override fun onCreate() {
        super.onCreate()
       
ParseObject.registerSubclass(User::class.java)

        Parse.initialize(
            Parse.Configuration.Builder(this)
            .applicationId("YourAppKey")
            .clientKey("YourClientKey")
            .server("https://parseapi.back4app.com")
            .build()
        )
    }

  }

在清单文件中：-

<application
        android:name=".App"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        ....
