inflateMenu不工作在工具欄裏面CollapsingToolbarLayout

Question

我想分配一個菜單到一個工具欄裏面的一個CollapsingToolbarLayout。這些是xml和Java代碼。 問題是inflateMenu根本沒有做任何事情。

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true"> 

    <android.support.design.widget.AppBarLayout 
     android:id="@+id/app_bar" 
     android:layout_width="match_parent" 
     android:layout_height="180dp" 
     android:fitsSystemWindows="true" 
     android:theme="@style/AppTheme.AppBarOverlay"> 

     <android.support.design.widget.CollapsingToolbarLayout 
      android:id="@+id/toolbar_layout" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:fitsSystemWindows="true" 
      app:contentScrim="?attr/colorPrimary" 
      app:layout_scrollFlags="scroll|exitUntilCollapsed"> 

      <ImageView 
       android:id="@+id/groupPhoto" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:scaleType="centerCrop" 
       app:layout_collapseMode="pin"/> 

      <android.support.v7.widget.Toolbar 
       android:id="@+id/toolbar" 
       android:layout_width="match_parent" 
       android:layout_height="?attr/actionBarSize" 
       app:layout_collapseMode="pin" 
       app:popupTheme="@style/AppTheme.PopupOverlay"> 

      </android.support.v7.widget.Toolbar> 

     </android.support.design.widget.CollapsingToolbarLayout> 
    </android.support.design.widget.AppBarLayout> 

    <android.support.v7.widget.RecyclerView 
     android:id="@+id/recyclerView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior"/> 

</android.support.design.widget.CoordinatorLayout> 

的Java：

@InjectView(R.id.toolbar) 
Toolbar toolbar; 
@InjectView(R.id.toolbar_layout) 
CollapsingToolbarLayout toolbarLayout; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_group_details); 
    ButterKnife.inject(this); 
    setSupportActionBar(toolbar); 
    toolbarLayout.setTitle(conversation.getTargetName()); 
    toolbar.setNavigationIcon(R.drawable.ic_keyboard_backspace_white_24dp); 
    toolbar.setNavigationOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      onBackPressed(); 
     } 
    }); 

    toolbar.inflateMenu(R.menu.menu_conversation_activity); 

    ... 
} 

這是菜單：

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     xmlns:tools="http://schemas.android.com/tools"> 
    <item 
     android:id="@+id/action_call" 
     android:icon="@drawable/ic_action_phone_24dp" 
     android:title="@string/secure_notes" 
     app:showAsAction="ifRoom"/> 
    <item 
     android:id="@+id/secureNote" 
     android:icon="@drawable/ic_pin_white_24dp" 
     android:title="@string/secure_notes" 
     app:showAsAction="ifRoom"/> 
    <item 
     android:id="@+id/deleteConversation" 
     android:icon="@drawable/ic_settings_white_24dp" 
     android:title="@string/delete_conversation" 
     app:showAsAction="never"/> 
    <item 
     android:id="@+id/clearHistory" 
     android:icon="@drawable/ic_settings_white_24dp" 
     android:title="@string/clear_history" 
     app:showAsAction="never"/> 
    <item 
     android:id="@+id/changeBackground" 
     android:icon="@drawable/ic_settings_white_24dp" 
     android:title="@string/change_background" 
     app:showAsAction="never"/> 

</menu> 

Answer 1

嘗試overiding的onCreateOptionsMenu（）方法這樣。

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.menu_conversation_activity, menu); 
    return true; 
} 

希望這是有益
