Answer 1

As the issue comes from the part that you are still in the same activity/fragment and the nested pref screen is just a dialog you can do the following:

• You can set preference click listener

• Get the root view from the dialog: (PreferenceScreen)preference).getDialog().getWindow() .getDecorView().getRootView());

• Recursively search until find a stub view (there is one, unfortunately I do not know the android.R.id.xxxxx) and set what layout you need as title which will look like the toolbar(You can inflate toolbar):

  private Toolbar toolbar;
  
      public void findViewStub(ViewGroup viewGroup) {
      int childCount = viewGroup.getChildCount();
      for (int i = 0; i < childCount; i++) {
          View childView = viewGroup.getChildAt(i);
          if( childView instanceof ViewStub){
              ((ViewStub)childView).setLayoutResource(R.layout.your_title_layout);
             toolbar =  ((ViewStub)childView).inflate();
          }
          if (childView instanceof ViewGroup) {
              findViewStub((ViewGroup) childView);
          }
      }
  
    }
  
  toolbar.setNavigationIcon();
  toolbar.setNavigationOnClickListener();
  toolbar.setTitle();
  

• In the layout you can put only a toolbar. And set the back icon. Register for click on it and having reference to the fragment, on click you can dismiss the dialog. You have set title and etc.
