AppBarLayout + TabLayout + CollapsingToolbarLayout + SwipeToRefresh

Question

我遇到了很多与我的问题有关的问题,但我发现没有人想要我正在寻找的行为.

我想要一个带有标签和应用栏的视图寻呼机,当所包含的片段可滚动并滚动(朝向底部)时,我希望应用栏消失,但是当向上滚动时,将标签留下以重新显示.其中一些片段包含SwipeToRefresh布局(有时会导致问题).我尝试了很多配置,总是会出错.

现在我没有崩溃效果(它总是隐藏)

和我的一个片段(滚动的一个):

                android:layout_height="match_parent"
                android:scrollbars="vertical" />

        </RelativeLayout>

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

</FrameLayout>

我不知道我到底做了什么,但从我开始写这个问题时,refreshLayout阻止了我的List上升(它刷新了)...

谢谢

------更正!

感谢Sir Ellie Zou,它现在适用于这个xml:

和片段布局:

    xmlns:tools="http://schemas.android.com/tools"
    xmlns:wheel="http://schemas.android.com/apk/res-auto"

    <com.pnikosis.materialishprogress.ProgressWheel
        android:id="@+id/progress_wheel"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:layout_gravity="center"
        wheel:matProg_barColor="#5588FF"
        wheel:matProg_progressIndeterminate="true" />

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipeRefreshLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">


        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scrollbars="vertical" />


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


</FrameLayout>

如果您不想要视差效果,则无需使用CollapsingToolbarLayout.

最重要的配置:

在工具栏中,设置app:layout_scrollFlags="scroll|enterAlways".

在ViewPager中,设置app:layout_behavior="@string/appbar_scrolling_view_behavior".

布局应如下所示:

<android.support.design.widget.CoordinatorLayout>

    <android.support.design.widget.AppBarLayout>

        <android.support.v7.widget.Toolbar/>

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

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

    <android.support.v4.view.ViewPager/>

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

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

将ProgressWheel你的的SwipeRefreshLayout解决您的问题,SwipeRefreshLayout无法刷新.
