选项卡上的 Android 导航抽屉

Question

我正在使用支持库中提供的新导航抽屉。将抽屉与标签一起使用时，抽屉菜单将显示在标签下方，如下所示。我如何确保抽屉菜单显示在选项卡上。 （它应该像没有标签一样显示抽屉菜单）

没有标签的抽屉菜单

带有标签的抽屉菜单

Answer 1

我遇到了同样的问题，我从 Roman Nurik（Android 团队）那里得到的答案是导航抽屉不应该与操作栏选项卡一起使用。

Answer 2

创建一个单独的片段，比如 TabsFragment 并将片段添加到主要活动的片段容器中。

可以使用以下代码将选项卡添加到选项卡片段中。

private FragmentTabHost mTabHost;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    mTabHost = new FragmentTabHost(getActivity());
    mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.fragment1);

    mTabHost.addTab(mTabHost.newTabSpec("TabA").setIndicator("TabA"),
           TabA.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("TabB").setIndicator("TabB"),
            TabB.class, null);

    return mTabHost;
}

这里，TabA 和 TabB 是选项卡的单独片段。您可以在各自的片段中实现各自选项卡的功能。 参考：http://developer.android.com/reference/android/support/v4/app/FragmentTabHost.html

Answer 3

我不确定 Action Bar 选项卡，但您可以使用 Pager Tab Strip 结合 Navigation Drawer 来获得类似于 Google Play Music 的导航模型，看看my post

Answer 4

这是我使用的解决方案看起来像（完美运行）： 我正在使用框架布局来交换片段，而选项卡式布局是基本片段上的选项卡。

activity_main.xml

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!--<include-->
    <!--android:id="@+id/toolbar"-->
    <!--layout="@layout/toolbar"/>-->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout

            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <android.support.design.widget.TabLayout
                android:id="@+id/sliding_tabs"
                android:layout_width="match_parent"
                scrol
                android:layout_height="wrap_content"/>

            <android.support.v4.view.ViewPager
                android:id="@+id/viewpager"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>
        </LinearLayout>
    </FrameLayout>

    <ListView
        android:id="@+id/navList"
        android:layout_width="200dp"
        android:layout_height="match_parent"
        android:layout_gravity="left|start"
        android:background="#ffeeeeee"/>

</android.support.v4.widget.DrawerLayout>

Answer 5

您可以手动隐藏负责渲染选项卡的视图：

public static void setActionBarNavigationVisibility(Activity activity, boolean visible) {
    // --- If the Tabs are BELOW ActionBar (narrow screens) --- 
    int actionViewResId = Resources.getSystem().getIdentifier("action_bar_container", "id", "android"); // @see http://stackoverflow.com/questions/20023483/how-to-get-actionbar-view
    View actionBarContainer = activity.findViewById(actionViewResId); // returns instance of com.android.internal.widget.ActionBarContainer (inaccessible)
    try {
        Field mTabContainerField = actionBarContainer.getClass().getDeclaredField("mTabContainer");
        if (mTabContainerField != null) {
            mTabContainerField.setAccessible(true);
            View mmTabContainer = (View) mTabContainerField.get(actionBarContainer);
            if (mmTabContainer != null)
                mmTabContainer.setVisibility(visible ? View.VISIBLE : View.GONE); // use GONE, so the mTabContainer below ActionBar does not take space in layout
        }
    } catch (Exception e) {
        // TODO handle exception
    }
}

只需从ActionBarDrawerToggle 的实现中调用此方法，如下所示：

public void onDrawerSlide(View drawerView, float slideOffset) {
        super.onDrawerSlide(drawerView, slideOffset);
        if (slideOffset == 0) { // 0 = drawer is closed             
            setActionBarNavigationVisibility(activity, true); //show Tabs when Drawer is closed             
        }
    }

public void onDrawerStateChanged(int newState) {
        super.onDrawerStateChanged(newState);
        //hides Tabs right after Drawer starts opening
        if (DrawerLayout.STATE_DRAGGING == newState || DrawerLayout.STATE_SETTLING == newState) {
            setActionBarNavigationVisibility(activity, false);
        }
    }

---

如果您在窄屏幕上使用 ActionBar.Tabs（选项卡自动显示在 ActionBar 下方），此解决方案将正常工作。但如果要处理所有其他导航场景（NavigationMode：List、CustomNavigationView 或 Tabs 直接显示在 ActionBar 中），第一种方法需要处理所有这些可能性：

public static void setActionBarNavigationVisibility(Activity activity, boolean visible) {
    try {
        /* 1. --- If the navigation items are showing in ActionBar directly. We have 3 options Spinner, Tabs, and CustomNav ---
         (When Tabs are showing BELOW ActionBar, is handled at the end) */
        int actionViewResId = Resources.getSystem().getIdentifier("action_bar", "id", "android"); // @see http://stackoverflow.com/questions/20023483/how-to-get-actionbar-view
        View actionBarView = activity.findViewById(actionViewResId); // returns instance of com.android.internal.widget.ActionBarView (inaccessible)
        if (actionBarView != null) {
            int visibility = visible ? View.VISIBLE : View.INVISIBLE; // not GONE, so it still takes space in ActionBar layout

            // handle tabs navigation
            Field mTabScrollViewField = actionBarView.getClass().getDeclaredField("mTabScrollView");
            if (mTabScrollViewField != null) {
                mTabScrollViewField.setAccessible(true);
                View mTabScrollView = (View) mTabScrollViewField.get(actionBarView); // instance of com.android.internal.widget.ScrollingTabContainerView (inaccessible)
                if (mTabScrollView != null)
                    mTabScrollView.setVisibility(visibility);
            }

            // handle Spinner navigation
            Field mSpinnerField = actionBarView.getClass().getDeclaredField("mSpinner"); // resp. mListNavLayout
            if (mSpinnerField != null) {
                mSpinnerField.setAccessible(true);
                View mSpinner = (View) mSpinnerField.get(actionBarView); // instance of android.widget.Spinner
                if (mSpinner != null)
                    mSpinner.setVisibility(visibility);
            }

            // handle Custom navigation
            Field mCustomNavViewField = actionBarView.getClass().getDeclaredField("mCustomNavView"); // resp. mListNavLayout
            if (mCustomNavViewField != null) {
                mCustomNavViewField.setAccessible(true);
                View mCustomNavView = (View) mCustomNavViewField.get(actionBarView);
                if (mCustomNavView != null)
                    mCustomNavView.setVisibility(visibility);
            }
        }
        // 2. --- If the Tabs are BELOW ActionBar (narrow screens) ---          
        ViewParent actionBarContainer = actionBarView.getParent(); // parent of ActionBarView is com.android.internal.widget.ActionBarContainer (inaccessible)
        Field mTabContainerField = actionBarContainer.getClass().getDeclaredField("mTabContainer");
        if (mTabContainerField != null) {
            mTabContainerField.setAccessible(true);
            View mmTabContainer = (View) mTabContainerField.get(actionBarContainer);
            if (mmTabContainer != null)
                mmTabContainer.setVisibility(visible ? View.VISIBLE : View.GONE); // now use GONE, so the mTabContainer below Actionbar does not take space in layout
        }

    } catch (Exception ex) {
        // TODO Handle exception...         
    }
}

WordPress Android 版本有你所说的问题的实现。

他们开发了一个名为“Horizo​​ntalTabView”的 TabView 模拟版本。他们为什么做这个和你（也是我）需要的完全一样。

WordPress github： https://github.com/WordPress/WordPress

相关来源：

• Horizo​​ntalTabView.java
• WPActionBarActivity.java
• res/theme_browser_activity.xml

希望这个提示对您有所帮助。

我认为现在问问题已经太晚了，但仍然如此。 如果您已经在使用导航抽屉并想要导航选项卡，请将这两个文件包含在您的项目文件夹中：

1) SlidingTabLayout.java http://developer.android.com/samples/SlidingTabsBasic/src/com.example.android.common/view/SlidingTabLayout.html

2) SlidingTabStrip.java http://developer.android.com/samples/SlidingTabsBasic/src/com.example.android.common/view/SlidingTabStrip.html

在导航抽屉片段中，包括以下内容：

private SlidingTabLayout mSlidingTabLayout;
    private  SamplePagerAdapter_tasks mPagerAdapter;
    private ViewPager mViewPager;

    public void onViewCreated(View view, Bundle savedInstanceState) {
        // BEGIN_INCLUDE (setup_viewpager)
        // Get the ViewPager and set it's PagerAdapter so that it can display items
        //fragment manager of a fragment,Return a private FragmentManager for placing and managing Fragments inside of this Fragment.

        mPagerAdapter = new SamplePagerAdapter_tasks(getChildFragmentManager(),Titles of Tabs(array of string),Numboftabs (integer));
        mViewPager = (ViewPager) view.findViewById(R.id.viewpager);
        mViewPager.setAdapter(mPagerAdapter);

        // Give the SlidingTabLayout the ViewPager, this must be done AFTER the ViewPager has had
        // it's PagerAdapter set.
        mSlidingTabLayout = (SlidingTabLayout) view.findViewById(R.id.sliding_tabs);
        mSlidingTabLayout.setDistributeEvenly(true); // this helps to all the tabs on screen to take equal spaces (eg. if 3 tabs each would take one-third of the total space on the screen)

        mSlidingTabLayout.setViewPager(mViewPager);

        // END_INCLUDE (setup_slidingtablayout)
    }

希望对你有帮助！

在我的 AppCompatActivity 中添加：

DrawerLayout drawerLayoutMenu =(DrawerLayout) findViewById(R.id.drawer_layout_menu);
RelativeLayout mDrawerPane =(RelativeLayout) findViewById(R.id.drawerPane);

我在工具栏菜单图标上调用它

if (drawerLayoutMenu.isDrawerOpen(mDrawerPane)) {
    drawerLayoutMenu.closeDrawer(mDrawerPane);
} else {
        drawerLayoutMenu.openDrawer(mDrawerPane);
}

Answer 9

Actionbar Navigaton Drawer 和 SwipeTabs 不能同时使用。您应该通过简单的 Tabhosts 使用 Actionbar 和 swipetabs 来实现 Navigation Drawer。您可以将 Tabhost 用于选项卡，并将片段用于每个选项卡的内部视图。片段应该通过 viewpager 来提供滚动/滑动效果。通过它们的方法将选项卡和 viewpager 相互连接

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<TabHost
    android:id="@+id/tabHost"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <HorizontalScrollView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:fillViewport="true"
            android:scrollbars="none" >

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >
            </TabWidget>
        </HorizontalScrollView>

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

            <android.support.v4.view.ViewPager
                android:id="@+id/viewPager_home"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </FrameLayout>
    </LinearLayout>
</TabHost>
