如何在 DialogFragment 中添加 PreferenceFragment

Question

我一直在尝试在 dialogFragment 中显示 PreferenceFragment，但我不确定如何...

我尝试将 preferencefragment 放入布局中

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical" android:layout_width="match_parent"
   android:layout_height="match_parent">
   <fragment
    android:id="@+id/settings_fragment"
    android:name="com.example.test.Fragments.SettingsFragment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
   </LinearLayout>

然后在 onCreateView 中使用它

    override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    super.onCreate(savedInstanceState);
    val view = inflater!!.inflate(R.layout.dialog_preference, container, false)
    return view
}

在我的主 activity 上，我这样称呼它：

   override fun onClick(view: View) {
    val id = view.id
        when (id) {
            R.id.btnSettings -> {
                val dialog = SettingsDialog();
                dialog.onCancel(object : DialogInterface {
                 override fun cancel() {
                     setTheme()
                 }

                 override fun dismiss() {

                 }
                })
                dialog.show(fragmentManager, null);
            }
        }
    }

我第一次调用它时，它出现了，但在第二次尝试时。它崩溃了.. 还有另一种方法可以在对话框中显示 PreferenceFragment 吗？有人可以让我知道该怎么做吗？谢谢

这是我收到的错误信息

Answer 1

我在另一个 post 中找到了答案： Duplicate ID, tag null, or parent id with another fragment for com.google.android.gms.maps.MapFragment

所以当我将它添加到我的 onDestroyView 时

     override fun onDestroyView() {
    super.onDestroyView()
    val frag = fragmentManager.findFragmentById(R.id.settings_fragment) as SettingsFragment?;
    if (frag != null)
        fragmentManager.beginTransaction().remove(frag).commit();
}

一切正常。如果有人能想出更好的方法来创建首选项对话框，请告诉我
