意向活动Utils，未在Manifest中声明-Kotlin，Android

Question

我正在尝试将Intent Activity Utils作为Kotlin中的扩展函数来实现。他们将从其他活动/片段开始活动。请向我建议最好的方法。

我试着解决这样的问题：

在"活动"中，我调用如下扩展函数：

when (view.id) {
PROFILE.actionViewId -> {
// Start Activity normally
startNewActivity(MyProfileActivity::class.java) 
}
PREPAID_RECHARGE.actionViewId -> {
// Dont start activity  and crash
startNewActivityForResult(RechargePrepaidActivity::class.java, RECHARGE_PREPAID_REQUEST_CODE) 
// Start Activity normally 
this.startActivityForResult(Intent(this, RechargePrepaidActivity::class.java), RECHARGE_PREPAID_REQUEST_CODE) 
}
TROUBLE_TICKETS.actionViewId -> {
startNewActivity(TroubleTicketsActivity::class.java) // Start Activity normally
}
HELP.actionViewId -> {
startNewActivity(HelpSectionActivity::class.java) // Start Activity normally
}

IntentTils.kt:

fun <T : BaseActivity> BaseActivity.startNewActivity(newActivity: Class<T>) {
val intent = Intent(this, newActivity)
this.startActivity(intent)
}
//fun BaseActivity.startNewActivity(newActivity: Class<*>) {
//    val intent = Intent(this, newActivity)
//    this.startActivity(intent)
//}
fun BaseActivity.startNewActivityForResult(newActivity: Class<*>, requestCode : Int) {
val intent = Intent(this, newActivity::class.java)
startActivityForResult(intent, requestCode)
}
fun BaseFragment.startNewActivity(newActivity: Class<*>) {
val intent = Intent(this.requireActivity(), newActivity::class.java)
this.startActivity(intent)
}
fun BaseFragment.startNewActivityForResult(newActivity: Class<*>, requestCode : Int) {
val intent = Intent(this.requireActivity(), newActivity::class.java)
startActivityForResult(intent, requestCode)
}

此外，活动在清单中声明-Kotlin，Android

<activity
android:name=".ui.recharge.RechargePrepaidActivity"
android:configChanges="locale|orientation|screenSize"
android:screenOrientation="portrait" />

这会正常启动活动：

startNewActivity(MyProfileActivity::class.java) // use extend func
startActivity(Intent(this, MyProfileActivity::class.java)) // use inherited Activity func 

但是，当我试图通过请求代码创建相同的函数来启动结果的活动时，它不起作用，当我使用继承的活动函数startActivityForResult()时，也没问题

// Dont start activity and crash
startNewActivityForResult(RechargePrepaidActivity::class.java, RECHARGE_PREPAID_REQUEST_CODE) 
// Start Activity normally 
startActivistyForResult(Intent(this, RechargePrepaidActivity::class.java), RECHARGE_PREPAID_REQUEST_CODE) 

奇怪的是，当我使用IntentUtils.startNewActivityForResult()应用程序时，会与
ActivityNotFoundException一起崩溃，但在正常使用Fragment.startActivityForResult()时，它没有这种行为：

Caused by: android.content.ActivityNotFoundException: 
Unable to find explicit activity class {/java.lang.Class}; have you declared this activity in your AndroidManifest.xml?
at ui.utils.view.IntentUtilsKt.startNewActivityForResult(IntentUtils.kt:19)
at ui.main.hamburgerMenu.HamburgerMenuActivity.onClick(HamburgerMenuActivity.kt:117)

问题出现在重复的::class.java调用中：

错误：

fun BaseActivity.startNewActivityForResult(newActivity: Class<*>, requestCode : Int) {
val intent = Intent(this, newActivity::class.java) //duplicated ::class.java
startActivityForResult(intent, requestCode) 
}

右：

fun BaseActivity.startNewActivityForResult(newActivity: Class<*>, requestCode : Int) {
val intent = Intent(this, newActivity) // removed ::class.java
startActivityForResult(intent, requestCode)
}
