爲Google Glass創建選項菜單

Question

按照StopWatch GDK示例中的指導原則和約定，我無法打開MenuOption。

我的應用程序編譯，並能輸出「@@@@ TEST」的」嵌入式日誌語句，但似乎沒有OptionsMenu。

https://developers.google.com/glass/develop/gdk/ui/immersion-menus

這是菜單的Android的API中的方法。

openOptionsMenu(); 

我立足的代碼關閉秒錶的慣例：

/* 
* 
* Menu Code 
*/ 
protected void onCreate(Bundle savedInstanceState){ 
    super.onCreate(savedInstanceState); 
} 

@Override 
public boolean onKeyDown(int keycode, KeyEvent event) { 
    if (keycode == KeyEvent.KEYCODE_DPAD_CENTER) { 
     openOptionsMenu(); 
     Log.v("@@@@","TEST"); 
     return true; 
    } 
    return false; 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.menu, menu); 
    return true; 
} 
@Override 
public boolean onPrepareOptionsMenu(Menu menu) { 
    // Implement if needed 
    return false; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle item selection. Menu items typically start another 
    // activity, start a service, or broadcast another intent. 
    switch (item.getItemId()) { 
     case R.id.stop: 
      //startActivity(new Intent(this, StopStopWatchActivity.class)); 
      Log.v("@@@@","HI"); 
       return true; 
     case R.id.read_aloud: 
      Log.v("@@@@","READ_ALOUD"); 
      return true; 
     default: 
      return super.onOptionsItemSelected(item); 
    } 
} 
    //open the optionsMenu to make sure 
@Override 
public void openOptionsMenu() { 
     super.openOptionsMenu(); 

} 

用於菜單的XML

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item 
     android:id="@+id/read_aloud" 
     android:title="@string/read_aloud" 
     android:icon="@drawable/ic_launcher"/> 
    <item 
     android:id="@+id/stop" 
     android:title="@string/stop" 
     android:icon="@drawable/ic_launcher"/> 
</menu>

編輯：我發現了我的問題。我評論說準備好的選項返回了錯誤狀態，這導致我的選擇不參與。

在這裏引用是一個很好的例子來正確地做到這一點。

感謝@ w9jds的幫助。

我無法找到問題在我的代碼中，但這裏有一個正確的菜單創建和一個水龍頭的工作示例解決方案。

https://github.com/w9jds/GlassMenuExample

什麼程序做是顯示出玻璃的應用程序，使一個Hello World卡。在點擊卡上創建一個具有「分享」選項的選項菜單。

此功能與卡片在時間線上的工作方式很相似。

菜單 - main.xml中

<menu xmlns:android="http://schemas.android.com/apk/res/android" > 

    <item 
     android:id="@+id/share_menu_item" 
     android:title="@string/share_label" 
     android:icon="@drawable/ic_share_50"/> 

</menu>
