我已经尝试了很高的等等,但不能弄清楚.

解决方法
CollapsingToolbarLayout与工具栏工作非常紧密,因此折叠的高度取决于工具栏.
我可以使用这种布局解决你的问题(注意它进入正常的CoordinatorLayout / AppBarLayout安装程序,使用Fab和NestedScrollView或RecyclerView):
- <android.support.design.widget.CollapsingToolbarLayout
- android:id="@+id/collapsing_toolbar"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:fitsSystemWindows="true"
- app:layout_scrollFlags="scroll|exitUntilCollapsed"
- app:statusBarScrim="?attr/colorPrimaryDark"
- app:contentScrim="@android:color/transparent"
- app:titleEnabled="false"
- >
- <!-- There isnt a contentSCrim attribute so the toolbar is transparent after being
- collapsed
- Disabled the title also as you wont be needing it -->
- <ImageView
- android:id="@+id/image_v"
- android:layout_width="match_parent"
- android:layout_height="360dp"
- android:layout_gravity="center"
- android:scaleType="centerCrop"
- android:src="@drawable/md2"
- android:fitsSystemWindows="true"
- app:layout_collapseMode="parallax"
- tools:ignore="ContentDescription"
- />
- <!-- Normal Imageview. Nothing interesting -->
- <android.support.v7.widget.Toolbar
- android:id="@+id/toolbar"
- android:layout_width="match_parent"
- android:layout_height="168dp"
- app:layout_collapseMode="pin"
- app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
- />
- <!-- The toolbar is styled normally. However we disable the title also in code.
- Toolbar height is the main component that determines the collapsed height -->
- <TextView
- android:text="@string/app_name"
- android:layout_width="match_parent"
- android:layout_height="wrap_content"
- android:layout_gravity="bottom"
- android:background="?attr/colorPrimaryDark"
- android:paddingLeft="72dp"
- android:paddingRight="0dp"
- android:paddingBottom="24dp"
- android:paddingTop="24dp"
- android:textColor="@android:color/white"
- android:textAppearance="@style/TextAppearance.AppCompat.Headline"
- />
- <!-- The title textView -->
- </android.support.design.widget.CollapsingToolbarLayout>
相关活动如下所示:
- ...
- setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
- getSupportActionBar().setDisplayHomeAsUpEnabled(true);
- // Disable toolbar title
- getSupportActionBar().setDisplayShowTitleEnabled(false);
- ...
