Question

我尝试使用Android提供的主/详细信息流模板创建应用程序。我尝试将多个操作栏菜单项添加到操作栏的主控部分和详细信息部分。

我使用了Android工作室的示例，但是当我为master e设置不同的菜单时，只显示菜单（右侧）。

活动细节是：

public class PDetailActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_p_detail);

    // Show the Up button in the action bar.
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    // savedInstanceState is non-null when there is fragment state
    // saved from previous configurations of this activity
    // (e.g. when rotating the screen from portrait to landscape).
    // In this case, the fragment will automatically be re-added
    // to its container so we don't need to manually add it.
    // For more information, see the Fragments API guide at:
    //
    // http://developer.android.com/guide/components/fragments.html
    //
    if (savedInstanceState == null) {
        // Create the detail fragment and add it to the activity
        // using a fragment transaction.
        Bundle arguments = new Bundle();
        arguments.putString(PDetailFragment.ARG_ITEM_ID, getIntent().getStringExtra(PatientDetailFragment.ARG_ITEM_ID));
        PatientDetailFragment fragment = new PDetailFragment();
        fragment.setArguments(arguments);
        getSupportFragmentManager().beginTransaction().add(R.id.p_detail_container, fragment).commit();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_p_detail, menu);
    return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == android.R.id.home) {
        // This ID represents the Home or Up button. In the case of this
        // activity, the Up button is shown. For
        // more details, see the Navigation pattern on Android Design:
        //
        // http://developer.android.com/design/patterns/navigation.html#up-vs-back
        //
        navigateUpTo(new Intent(this, PListActivity.class));
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}

片段细节是：

public class PDetailFragment extends Fragment {
/**
 * The fragment argument representing the item ID that this fragment
 * represents.
 */
public static final String ARG_ITEM_ID = "item_id";

/**
 * The dummy content this fragment is presenting.
 */
private PObj mItem;

/**
 * Mandatory empty constructor for the fragment manager to instantiate the
 * fragment (e.g. upon screen orientation changes).
 */
public PDetailFragment() {
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setHasOptionsMenu(true);
    ((PatientDetailActivity)getActivity()).getSupportActionBar().setTitle("Detail");

    if (getArguments().containsKey(ARG_ITEM_ID)) {
        // Load the dummy content specified by the fragment
        // arguments. In a real-world scenario, use a Loader
        // to load content from a content provider.
        mItem = PListFragment.pObjHashMap.get(getArguments().getString(ARG_ITEM_ID));
    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_p_detail, container, false);

    // Show the dummy content as text in a TextView.
    if (mItem != null) {
        ((TextView) rootView.findViewById(R.id.p_detail)).setText(mItem.name);
    }

    return rootView;
}
}

问题是我只显示一个菜单（主菜单）而没有显示菜单（细节）在这个截图中

在此屏幕截图中，我只有一个菜单，而+位于右侧，而不是标题旁边的左侧＆＃34; Master＆＃34;。在与标题相关的部分中，标题甚至是符号X都缺失。

如何解决我的问题？

多个操作栏主/详细信息（一个用于主控，一个用于详细信息）
