我不能在没有工具栏布局的情况下在滚动视图和选项卡布局中使用viewpager？

Question

I want to use

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

            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent">

                <RelativeLayout
                    android:id="@+id/main_content"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:orientation="vertical"
                    tools:visibility="gone">

                    <RelativeLayout
                        android:id="@+id/image"
                        android:layout_width="match_parent"
                        android:layout_height="220dp">

                        <ImageView
                            android:id="@+id/cover_image"
                            android:layout_width="match_parent"
                            android:layout_height="match_parent"
                            android:scaleType="centerCrop"/>

                    </RelativeLayout>

                    <RelativeLayout
                        android:id="@+id/tab_layout"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_below="@id/image"
                        android:background="@color/card_background">

                        <android.support.design.widget.TabLayout
                            android:id="@+id/topTabs"
                            style="@style/TextAppearance.Tab"
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content"
                            app:tabBackground="@color/bpWhite"
                            app:tabGravity="fill"
                            app:tabMode="fixed"
                            app:tabTextColor="@color/secondary_text_color"
                            custom:tabIndicatorColor="@color/secondary_text_color"
                            custom:tabIndicatorHeight="2dp" />

                        <View
                            android:layout_width="match_parent"
                            android:layout_height="2dp"
                            android:layout_below="@id/topTabs"
                            android:background="@drawable/tab_layout_drop_shadow" />
                    </RelativeLayout>

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

                </RelativeLayout>
                </RelativeLayout>
</android.support.v4.widget.NestedScrollView>

It is not able to scroll, that view-pager or tab-layout is not able scroll I tried all the ways.

1.Disable the touch event in view-pager and enable the touch event for scroll-view.

2.Tried other scroll-views like Nestedscrollview, Parallaxscrollview, Coordinator layout.If I use coordinator layout then not able to change he toolbar.

3. I used fillviewport true for all the scrollviews. but still it is not able to scroll.

Any Other ways to fix the issue.

Answer 1

您可以在没有工具栏的情况下使用视图寻呼机，但在没有工具栏的情况下不能使用选项卡。

Answer 2

Although it remains unclear, what you are trying to achieve here, there is no problem in the layout, really.

If you set up the Design Support Library correctly and

if you did not mess up your listeners with your attempts to disable some touch events and

if you take out the tools:visibility="gone" attribute (in order to show anything that can be scrolled) and

if you decide on a specific height (or wrap_content ) for the ViewPager and

optionally if you take out the first RelativeLayout s which is unnecessary,

then you should be able to scroll. At least I am inside the layout editor of Android Studio.
