Android 片段和滚动条

Question

scrolling activity

我正在尝试使用片段（底部栏）进行此活动。

error page

但结果是这样的。 我删除了 style.xml (Light.NoActionBar) 中的操作栏，但它保留了空间。

这里是代码

activity_main.xml

<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
            }
        }
    });

转到清单 -> 将以下属性添加到 MainActivity 条目 -

android:theme ="AppCompat.NoActionBar"
