替换 PreferencesFragment 中已弃用的 setTargetFragment()

Question

我无法弄清楚如何在下面的代码示例中替换setTargetFragment()，这显然来自我的Preferencesfragment：

override fun onPreferenceStartFragment(
    caller: PreferenceFragmentCompat,
    pref: Preference
): Boolean {
    // Instantiate the new Fragment
    val args = pref.extras
    val fragment = supportFragmentManager.fragmentFactory.instantiate(
        classLoader,
        pref.fragment
    ).apply {
        arguments = args
        setTargetFragment(caller, 0) // <-- DEPRICATED CODE
    }

    // Replace the existing Fragment with the new Fragment
    supportFragmentManager.beginTransaction()
        .replace(R.id.settings, fragment)
        .addToBackStack(null)
        .commit()
    title = pref.title
    return true
}

对于我的 Android Studio 知识水平来说，未知数太多了！该参考资料有所帮助，但仍然感到困惑： How to replace setTargetFragment() now that it is deprecated

Answer 1

好吧，显然这可行，但我不确定我是否真的了解发生了什么：

override fun onPreferenceStartFragment(
    caller: PreferenceFragmentCompat,
    pref: Preference
): Boolean {
    // Instantiate the new Fragment
    val args = pref.extras
    val fragment: Fragment = supportFragmentManager.fragmentFactory.instantiate(classLoader, pref.fragment)
    fragment.arguments = args
    supportFragmentManager.beginTransaction().replace(R.id.settings, fragment).addToBackStack(null).commit()
    supportFragmentManager.setFragmentResultListener("requestKey", fragment) { _, _ ->   }
return true
}
