我有一个collapsingToolbarLayout,如何更改其最小高度?我曾在xml minHeight =“ 100dp”中尝试过,但确实有用。它通常会折叠到顶部。谁能告诉我如何将其最小高度设置为150dp?
<android.support.design.widget.CoordinatorLayout
android:layout_width="0dp"
android:layout_height="0dp"
android:fitsSystemWindows="true"
app:layout_constraintBottom_toTopOf="@+id/bottom_nav_master_home"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar_master_home_activity"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/toolbar_collapse"
android:layout_width="match_parent"
android:layout_height="256dp"
android:layout_marginBottom="100dp"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed|snap"
app:titleEnabled="false">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/color_master_background_dark"
app:layout_collapseMode="parallax
android:background="@color/color_master_background_dark"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar_master_home_activity"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:title=" "
app:titleTextColor="@color/color_text_dark" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<fragment
android:id="@+id/fragment_nav_host_main_master"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:defaultNavHost="true"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
app:navGraph="@navigation/nav_graph_master_main" />
</android.support.design.widget.CoordinatorLayout>
我确实添加了marginBottom但仍然没有结果吗?我在这里做错什么了吗?我编辑了上面的代码..

将工具栏的底部边距设置为要在折叠版本中保留的任何空间。
