Question

我的应用程序，有导航抽屉和滑动标签。

问题：我在主要活动中实现了滑动标签，导航抽屉项目的onclick打开了不同的片段，它工作正常，但它隐藏在我在主要活动中实现的滑动标签内，

我的目标：我希望默认页面是滑动标签，如果我点击导航图标，滑动标签页必须关闭并打开我为导航图标实现的片段中的内容。

代码如下。

activity_main.xml中：

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


<LinearLayout
    android:id="@+id/container_toolbar"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">


    <include
        android:id="@+id/app_bar"
        layout="@layout/app_bar" />

    <FrameLayout
        android:id="@+id/container_body"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1" >
    <tabs.SlidingTabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/ColorPrimary"
        android:elevation="2dp" />

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

    </FrameLayout>
</LinearLayout>


<fragment
    android:id="@+id/fragment_navigation_drawer"
    android:name="keleno.example.ramz.mapper_city.FragmentDrawer"
    android:layout_width="260dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:layout="@layout/fragment_nav_drawer"
    tools:layout="@layout/fragment_nav_drawer" />

Answer 1

您必须将滑动标签设为片段，以便可以将其替换为其他片段，而不是进行滑动活动

Answer 2

如上所述，您只想显示一个片段中的选项卡，那么您应该删除主布局中的选项卡并直接在片段布局中使用它。

保持

drawerlayout＆gt; 工具栏＆gt;片段[你的片段包含使用fragment.xml膨胀的标签]＆gt; mainactivity布局文件中的navigationview

将标签xml代码移到其他fragment.xml文件中

Answer 3

以下是来自Google @ SlidingTabsBasic的精彩网页，我已经使用过了。我相信它可以满足您将滑动多个标签作为主要用户界面的要求。 MainActivity从FragmentActivity扩展为子类。换句话说，MainActivity可能是一个片段，但我不建议你让示例项目更复杂，让它开始变得简单。

替换片段无效
