Question

Hello Guys，

我的问题与我的应用程序中的双工具栏在膨胀（或说替换）片段时有关。我有一个活动类，其中包含导航抽屉及其带有导航工具栏图标的工具栏。

有一些片段我不想显示活动工具栏我只需要显示片段工具栏：

但是在替换它显示活动以及片段工具栏时，任何建议对我都有帮助。

我试过了：

我的片段：

public class FoodDetailsFragment extends Fragment{
    View view;
    private Toolbar toolbar;
    private ImageView imageView,tabBg;
    private CollapsingToolbarLayout collapsingToolbar;
    private TabPagerAdapter tabPagerAdapter;
    private ViewPager mViewPager;
    private TabLayout mTabLayout;
    CoordinatorLayout.Behavior behavior;
    SendMessage listener;

     public  interface SendMessage{
        void sendData(String s);
}

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try{
            listener= (SendMessage) activity;

        }catch (ClassCastException exp){
            throw new ClassCastException("Class Cast Exp");
        }


    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
       view=inflater.inflate(R.layout.food_details,container,false);
        setHasOptionsMenu(true);
        listener.sendData("ds");

        imageView= (ImageView) view.findViewById(R.id.backdrop);
        tabBg= (ImageView) view.findViewById(R.id.tabBg);
        collapsingToolbar=(CollapsingToolbarLayout) view.findViewById(R.id.collapsing_toolbar);

        mTabLayout.setTabsFromPagerAdapter(tabPagerAdapter);
        mTabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
        mTabLayout.setupWithViewPager(mViewPager);

        mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {

Answer 1

使用主题

<style name="AppCompat" parent="Theme.AppCompat.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

    </style>

Answer 2

使用此主题

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

Answer 3

在样式中使用try { var o_userId =mongoose.Types.ObjectId(req.params.userId); var query = { userId: o_userId }; var projection = '_id $.userId $.value'; UserRef.find(query, projection, function (err, usrrefs) { if (err) return next(err); res.send(usrrefs); console.log("userref fetched Properly"); }); } catch (err) { console.log('Error While Fetching ' + err); return next(err); }删除蓝色工具栏。

Answer 4

使用

((AppCompatActivity)getActivity()).getSupportActionBar().hide();

以编程方式隐藏操作栏

使用主题：

<style name="AppCompat" parent="Theme.AppCompat.NoActionBar">

</style>

Answer 5

<android.support.v7.widget.Toolbar
            android:id="@+id/toolbarone"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

从fragment.xml中删除此tootlbar

或隐藏活动的工具栏

      ((AppCompatActivity)getActivity()).getSupportActionBar().hide();

双工具栏在片段上显示
