Android的片段和滾動條

Question

scrolling activity

我正在嘗試使用片段（底部欄）進行此活動。

error page

但它出來是這樣的。 我刪除了style.xml（Light.NoActionBar）中的操作欄，但它保留了空間。

這裏的代碼

activity_main.xml中

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/fragmentContainer" 
android:layout_width="match_parent" 
android:padding="16dp" 
android:layout_height="match_parent"> 

SearchFragment.java

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

    //Toolbar 
    final Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar); 
    AppCompatActivity activity = (AppCompatActivity) getActivity(); 

    activity.setSupportActionBar(toolbar); 
    activity.getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) view.findViewById(R.id.collapse_toolbar); 
    collapsingToolbarLayout.setTitle("scrolling bar"); 

    return view; 
} 

MainActivity.java

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

    //Bottom Tool Bar 
    bottomBar = BottomBar.attach(this, savedInstanceState); 

    bottomBar.setFragmentItems(getSupportFragmentManager(), R.id.fragmentContainer, 
      new BottomBarFragment(SearchFragment.newInstance("Content for search."), R.drawable.ic_update_white_24dp, "검색"), 
      new BottomBarFragment(SampleFragment.newInstance("Content for favorites."), R.drawable.ic_favorite_white_24dp, "관심 리스트"), 
      new BottomBarFragment(SampleFragment.newInstance("Content for food."), R.drawable.ic_local_dining_white_24dp, "메시지"), 
      new BottomBarFragment(SampleFragment.newInstance("Content for locations."), R.drawable.ic_location_on_white_24dp, "프로필") 
    ); 

    // Setting colors for different tabs when there's more than three of them. 
    bottomBar.mapColorForTab(0, "#3B494C"); 
    bottomBar.mapColorForTab(1, "#00796B"); 
    bottomBar.mapColorForTab(2, "#7B1FA2"); 
    bottomBar.mapColorForTab(3, "#FF5252"); 

    bottomBar.setOnItemSelectedListener(new OnTabSelectedListener() { 
     @Override 
     public void onItemSelected(int position) { 
      switch (position) { 
       case 0: 
        // Item 1 Selected 
      } 
     } 
    });
