英文:
If I pass fragment object throw function is clean code
问题
例如：
object ThisClassForNavigateToSomeFragment {
internal fun navigateToFragment1(
productId: Long, navigateId: Int, fragment: Fragment
) {
val bundle = Bundle()
bundle.putLong("product_id", productId)
fragment.findNavController().navigate(navigateId, bundle)
}
internal fun navigateToFragment(
productId: Long, navigateId: Int, fragment: Fragment
) {
val bundle = Bundle()
bundle.putLong("product_id", productId)
fragment.findNavController().navigate(navigateId, bundle)
}
}
这是干净的代码吗？如果我通过一个函数传递 fragment，这样做好吗？
英文:
For example:
object ThisClassForNavigateToSomeFragment{
internal fun navigateToFragment1(
productId: Long, navigateId:Int, fragment:Fragment) {
val bundle = Bundle()
bundle.putLong("product_id", productId)
fragment.findNavController().navigate(navigateId, bundle)
}}
internal fun navigateToFragment(
productId: Long, navigateId:Int, fragment:Fragment) {
val bundle = Bundle()
bundle.putLong("product_id", productId)
fragment.findNavController().navigate(navigateId, bundle)
}}
Is this clean code, is this good if I pass fragment throw a function?

为什么要为导航使用不同的函数？您可以在BaseFragment或BaseActivity中简单地添加一个方法，如下所示。 （然后在片段或活动中扩展此方法）
protected fun navigate(directions: NavDirections) {
findNavController().navigate(directions)
}
这很简单，您实际上不需要一个对象来执行这个简单的任务。
由于您传递了NavDirection对象，您可以选择传递带有额外信息或不带额外信息的对象。
英文:
Why do you want to have different functions for navigation? You can simply add a method in BaseFragment or BaseActivity like the following. ( And extend this in your fragments or activity)
protected fun navigate(directions: NavDirections) {
findNavController().navigate(directions)
}
This is simple, and you really don't need an object to do this simple task.
Since you pass NavDirection object, you can either pass one with or without extras.
