圖標不顯示在操作欄 - Android

我試圖在操作欄上顯示一個攝像頭圖標，但它不起作用。菜單顯示並正常工作，但相機圖標不顯示。你能幫我麼？圖標不顯示在操作欄 - Android

預先感謝您。

婁的onCreate（）

public class DailySelfieActivity extends ListActivity { 

static final int REQUEST_IMAGE_CAPTURE = 1; 
public final static String EXTRA_MESSAGE = "br.com.cfb.daily_selfie.MESSAGE"; 
private static final String TAG = "DS-DailySelfieActivity"; 
private final static int INTENT_ID = 322; 

private SelfieViewAdapter mAdapter; 
private SelfieRecord mSelfieRecord; 

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

    ListView selfieListView = getListView(); 
    final View footerView = ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_view, null, false); 
    selfieListView.addFooterView(footerView); 
    mAdapter = new SelfieViewAdapter(this.getApplicationContext()); 
    loadListAdapter(); 
    setListAdapter(mAdapter); 

    //  Create Alarm to take a selfie 
    Alarm mAlarm = new Alarm(getApplicationContext()); 

    //  Enable filtering when the user types in the virtual keyboard 
    //  selfieListView.setTextFilterEnabled(true); 

    //  Set an setOnItemClickListener on the ListView 
    selfieListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View view, 
           int position, long id) { 

    //    Display a Toast message indicting the selected item 
      Toast.makeText(getApplicationContext(), "position = " +position + " id = " +id 
        , Toast.LENGTH_LONG).show(); 
      mSelfieRecord = (SelfieRecord) mAdapter.getItem(position); 
      Toast.makeText(getApplicationContext(), "Date = " +mSelfieRecord.getDate() 
        , Toast.LENGTH_LONG).show(); 
      //    Display Picture 
      Intent intent = new Intent(DailySelfieActivity.this, DisplayPictureActivity.class); 
      Bitmap mPicture = mSelfieRecord.getPicture(); 
      intent.putExtra(EXTRA_MESSAGE, mPicture); 
      startActivity(intent); 
     } 
    }); 
}

婁OnCreateOptionsMenu

public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.menu_daily_selfie, menu); 
    return true; 
}

請張貼您的活動。 –

它是您的可繪製文件夾中的圖標？ – acostela

您是否已將菜單文件的名稱添加到'onCreateOptionsMenu'中的'inflater.inflate（R.menu.menu_file_name，menu）'？ –

ic_menu_camera怎麼樣？儘管我在其他地方看到ic_action_camera的引用，但這並不適合我。我也有機會獲得android:icon="@android:drawable/ic_menu_camera"雖然（注意添加@android:drawable）的

或者，如@acostela指出，要確保它在你的繪製文件夾中只使用 android:icon="@drawable/ic_action_camera"。

@Xarep，ic_action_camera它在可繪製目錄中。我也嘗試android：icon =「@ android：drawable/ic_menu_camera」並運行應用程序，圖標仍然不顯示。謝謝。 – Carlos

嗨夥計們，我原來的活動擴展了一個ListView，所以我改變和擴展了ActionBar，它運行良好。 – Carlos

嗯，不知道爲什麼擴展ListActivity會導致這個問題，但很高興你得到它的工作@Carlos – Xakep

我原來的Activity正在擴展一個ListView，所以我改變並擴展了ActionBar，它運行良好。

謝謝，卡洛斯
