如何在折叠工具栏布局下添加 viewpager 和 tablayout

Question

我在 Whosebug 中尝试了针对此问题的所有解决方案，但没有任何帮助。首先，我想实现这样或类似的布局：

根据 Whosebug 中的一些问题，例如 this 我能够实现这种布局：

用这个 xml 文件 :

<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/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/MyAppbar"
        android:layout_width="match_parent"
        android:layout_height="256dp"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapse_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@android:color/transparent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <ImageView
                android:id="@+id/bgheader"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@drawable/aks"
                android:fitsSystemWindows="true"
                android:scaleType="centerCrop"
                app:layout_collapseMode="parallax" />

            <android.support.v7.widget.Toolbar
                android:id="@+id/MyToolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:theme="@style/ThemeOverlay.AppCompat.Dark"
                app:layout_collapseMode="pin" />

            <com.majid.whiteboard.utils.CustomTabLayout
                android:id="@+id/tab_layout_detail_activity"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@color/colorPrimary"
                app:paddingEnd="20dp"
                app:paddingStart="20dp"
                app:tabGravity="fill"
                app:tabIndicatorColor="@color/silver"
                app:tabIndicatorHeight="4dp"
                app:tabMode="fixed"
                app:tabSelectedTextColor="@color/grid_text_color"
                app:tabTextColor="@color/grid_text_color" />

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

    <android.support.v4.view.ViewPager
        android:id="@+id/view_pager_detail_activity"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

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

一切正常，但现在我有两个问题:

1.Tablayout 转到屏幕顶部，但我想在折叠工具栏下添加它

2.I 只能在折叠区域折叠工具栏（意味着只能在图片和顶部）并且它不能在屏幕上的其他地方工作。

以下是我在我的应用程序中使用 viewpager 和 TabLayout 永久粘性 toolbar 的方法。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

并且在 Activity 内我使用了-

CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout)findViewById(R.id.collapsing_toolbar);
ImageCheckbox user_follow_top = (ImageCheckbox)findViewById(R.id.user_follow_top);
RoundedNetworkImageView imgProfile = (RoundedNetworkImageView) findViewById(R.id.user_dp);
RoundedNetworkImageView getImgProfileTop = (RoundedNetworkImageView)findViewById(R.id.img_profile_top);

AppBarLayout.OnOffsetChangedListener mListener = new AppBarLayout.OnOffsetChangedListener() {
                        @Override
                        public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
                            if(collapsingToolbarLayout.getHeight() + verticalOffset < 1.5 * ViewCompat.getMinimumHeight(collapsingToolbarLayout)) {
                                getImgProfileTop.animate().alpha(1).setDuration(400);
                                user_follow_top.animate().alpha(1).setDuration(400);
                                collapsingToolbarLayout.setTitle(username);
                            } else {
                                getImgProfileTop.animate().alpha(0).setDuration(400);
                                user_follow_top.animate().alpha(0).setDuration(400);
                                collapsingToolbarLayout.setTitle("");
                            }
                        }
                    };
AppBarLayout appBarLayout = (AppBarLayout)findViewById(R.id.app_bar_layout);
appBarLayout.addOnOffsetChangedListener(mListener);

这是输出-

不滚动

滚动后
