我有我的preferenceActivity出现一个菜单。在我的孩子preference屏幕，我失去了菜单（不弹出）。我怎样才能让我的菜单弹出的儿童呢？

I have a menu that comes up for my PreferenceActivity. In my child preference screens, I lose that menu (doesn't pop up). How can I make my menu pop up for children too?

感谢。

例如：

<PreferenceScreen
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:persistent="true">
  <PreferenceCategory
    android:title="some category"
    android:persistent="true"
    android:orderingFromXml="true">
    <PreferenceScreen
      android:title="some child screen"
      android:summary="some child summary">
      <PreferenceCategory
         ...

第一preference屏幕有菜单，但是当你点击的孩子之一，没有菜单。你怎么能添加菜单？

The first preference screen has the menu, but when you click on the child one, no menu. How can you add the menu?

我面对类似的问题。这里是我做过什么来克服这个问题。

I faced the similar issue. Here is what I did to overcome the issue.

在preferenceActivity onCreate方法，

In the preferenceActivity onCreate method,

        final PreferenceScreen childPref = (PreferenceScreen) findPreference("childPrefId");
        childPref .setOnPreferenceClickListener(new OnPreferenceClickListener() {

            @Override
            public boolean onPreferenceClick(Preference preference)
            {
                Intent intent = new Intent(PreferenceActivity.this, YourSettings.class);
                intent.setAction("ShowChildPref");
                startActivity(intent);                    
                return true;
            }
        });

        Intent intent = getIntent();
        if(intent.getAction() != null && intent.getAction().equals("ShowChildPref"))
        {                
            setPreferenceScreen(childPref);

            /*Set Flags here based on intent what kind of menu to create in OnPrepareMenu.*/
        }
    }
