Question

在我的布局中，我将CoordinatorLayout作为垂直方向的父级， 1 - 工具栏 2 - LinearLayout中的内容 3 - TabLayout 4 - ViewPager

当我向上滚动时，应使用视图寻呼机滚动内容，并且应使用工具栏附加标签布局。

怎么做？

<android.support.design.widget.CoordinatorLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/coordinatorLayout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <!-- AppBar Layout   -->
        <android.support.design.widget.AppBarLayout
            android:id="@+id/appBarLayout"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="fill_parent"
                android:layout_height="?attr/actionBarSize"
                android:isScrollContainer="true"
                android:background="?attr/colorPrimary"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

            <RelativeLayout
                app:layout_scrollFlags="scroll|enterAlways"

                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <ImageView
                    android:layout_centerInParent="true"
                    android:src="@mipmap/ic_launcher"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content" />

            </RelativeLayout>
            <!-- Tab Layout for creating tabs -->
            <android.support.design.widget.TabLayout
                android:id="@+id/tabLayout"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" />
        </android.support.design.widget.AppBarLayout>
        <!-- Helps handing the Fragments for each Tab -->
        <android.support.v4.view.ViewPager
            android:id="@+id/viewPager"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />
    </android.support.design.widget.CoordinatorLayout>

Answer 1

您需要将ViewPager包装在NestedScrollView中，并将布局行为移至滚动视图。

        .

        </android.support.design.widget.AppBarLayout>

        <android.support.v4.widget.NestedScrollView
            android:id="@+id/nestedScrollView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">

            <android.support.v4.view.ViewPager
                android:id="@+id/viewPager"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </android.support.v4.widget.NestedScrollView
