我在看的 chrisbanes / cheesesquare ，我试图把TabLayout一个工具栏里面CollapsingToolbarLayout，这里是我的code

I am looking at the chrisbanes/cheesesquare and I am trying to put TabLayout with a Toolbar inside a CollapsingToolbarLayout, and here is my code

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

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/detail_backdrop_height"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/primary_dark"
            android:minHeight="150dip"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginStart="48dp"
            app:expandedTitleMarginBottom="60dp"
            app:expandedTitleMarginEnd="64dp">

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

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="110dip"
                android:layout_gravity="top"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                app:layout_collapseMode="pin" />

            <android.support.design.widget.TabLayout
                android:id="@+id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"/>

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

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

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

这给像这样的CollapsingToolbar被打开时，这也正是我要寻找的是什么：

This puts on something like this when the CollapsingToolbar is opened which is exactly what I am looking for:

但是，当我崩溃（通过拉动图像上）我得到这样的事情

But when I collapse it (by pulling the image up) I get something like this

这是因为我已经设置工具栏有110dip的高度的原因，如果我离开的默认设置选项卡和工具栏标题重叠。所以我在寻找正确的方式来做到这一点，这样的工具栏的标题得到它的在appbar正确的地方和tablayout是在它之下。有没有一种方法可以做到这一点？

And this is due to the reason I've set the Toolbar to have a height of 110dip if I leave the default settings the Tabs and the toolbar title overlap. So I am looking for the right way to do that so that the title of the Toolbar gets it's right place on the appbar and the tablayout is under it. Is there a way this can be achieved ?

推荐答案

这是我成功地做到这一点，我不认为这是但如果有人发现更好的方法，请随意张贴的答案最好的解决办法的途径。

Here's the way I managed to do this, I don't think that's the best solution though if anyone finds a better way please feel free to post the answer.
