Handy Idiom: Pass Arguments to Android Fragment using Kotlin + Anko

import android.support.v4.app.Fragment
import org.jetbrains.anko.bundleOf

/**
 * Pass arguments to a Fragment without the hassle of
 * creating a static newInstance() method for every Fragment.
 *
 * Declared outside any class to have full access in any
 * part of your package.
 * 
 * Usage: instanceOf<MyFragment>("foo" to true, "bar" to 0)
 *
 * @return Returns an instance of Fragment as the specified generic type with the params applied as arguments

inline fun <reified T : Fragment> instanceOf(vararg params: Pair<String, Any>)
		= T::class.java.newInstance().apply {
	arguments = bundleOf(*params)
}

Nice!

You're the man

Nice!

without the hassle of creating a static newInstance() method for every Fragment.

But then you call: T::class.java.newInstance()

So you actually need the newInstance, don't you?

how to using it?
i have fragment with companion object like this
companion object {
private const val SEGMENT_NAME = "segment_name"
private const val TEAMID = "teamid"
private const val TITLE = "title"
fun newInstance(segmentName: String?, teamId: String?, titleBar: String?): NextFragment? = NextFragment().apply {
val args = bundleOf(
SEGMENT_NAME to segmentName,
TEAMID to teamId,
TITLE to titleBar
)
val fragment: NextFragment?=null
fragment?.arguments =args
return fragment
}
}

and how read in fragment OnCreateView
in my activity set by me like this:
private fun loadNextFragment(savedInstanceState: Bundle?) {
if (savedInstanceState == null) {
val leagueFragment = instanceOf(
"SEGMENT_NAME" to "eventsnextleague.php",
"TEAMID" to "4329", "TITLE" to "Next League")
supportFragmentManager
.beginTransaction()
.replace(
R.id.main_container,
leagueFragment,
NextFragment::class.java.simpleName
)
.commit()
}
}
thank

definitively a good to have function
