我不知道如何在下面的代码示例中替换setTargetFragment（），这显然来自我的首选项片段：
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，有太多的未知！这个参考很有帮助，但是仍然很困惑:既然setTargetFragment()已经被弃用，如何替换它
好吧，显然这有效，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
}
