使用TabLayout時缺少動作欄

Question

我已經從支持庫實現了TabLayout，但它會覆蓋我需要的ActionBar。

這是對其進行設置和膨脹的選項卡並加載選項卡的片段的活性。

public class TabsActivity extends android.support.v4.app.FragmentActivity { 


    FloatingActionButton fab; 

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

     setTitle("Fuel Logger"); 

     ActionBar a = getActionBar(); 




     ViewPager vp = (ViewPager) findViewById(R.id.viewpager); 
     vp.setAdapter(new FragmentPagerAdapter(
       getSupportFragmentManager(), TabsActivity.this 
     )); 

     TabLayout tabLayout = (TabLayout) findViewById(R.id.fuel_sliding_tabs); 
     tabLayout.setupWithViewPager(vp); 

    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.fuel_menu, menu); 
     MenuItem refresh = menu.findItem(R.id.action_settings); 
     refresh.setEnabled(true); 
     return true; 
    } 


    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     int id = item.getItemId(); 

     switch (id){ 
      case R.id.action_settings: 

       break; 
      case R.id.action_favorite: 

       return true; 

      default: 

     } 
      return super.onOptionsItemSelected(item); 
     } 


    } 

和XML只是視圖尋呼機和標籤佈局

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <android.support.design.widget.TabLayout 
     style="@style/FuelTabLayout" 
     android:id="@+id/fuel_sliding_tabs" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:tabMode="scrollable" 
     android:layout_alignParentTop="true" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" /> 

    <android.support.v4.view.ViewPager 
     android:id="@+id/viewpager" 
     android:layout_width="match_parent" 
     android:layout_height="0px" 
     android:layout_weight="1.27" 
     android:background="@android:color/white" 
     android:layout_alignParentBottom="true" 
     android:layout_below="@+id/fuel_sliding_tabs" /> 

    <android.support.design.widget.FloatingActionButton 
     android:id="@+id/fab" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:clickable="true" 
     android:src="@android:drawable/ic_menu_set_as" 
     app:layout_anchorGravity="bottom|right|end" 
     app:backgroundTint="@color/colorAccent" 
     android:layout_gravity="right" 
     android:cropToPadding="true" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentEnd="true" 
     android:layout_marginRight="20dp" 
     android:layout_marginEnd="20dp" 
     android:layout_marginBottom="20dp" /> 


</RelativeLayout> 

和片段代碼是或多或少相同的每個片段類

Public class SummaryFragment extends android.support.v4.app.Fragment { 

public static final String ARG_PAGE = "SUMM_PAGE"; 
private int mTab; 

public static SummaryFragment newInstance(int page){ 
    Bundle args = new Bundle(); 
    args.putInt(ARG_PAGE, page); 
    SummaryFragment frag = new SummaryFragment(); 
    frag.setArguments(args); 
    return frag; 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    mTab = getArguments().getInt(ARG_PAGE); 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container,  Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.fragment_tab_summary, null); 


    return view; 
}

第一示例添加工具欄，並使用LinearLayout女巫有水平方向 並設置樣式NoActionBar 希望它幫助你
