我想隐藏我的 AppBarLayout 以动态添加将占用屏幕高度的视图。为此,我想通过将 AppBarLayout 的可见性设置为 GONE 来临时删除视图。视图不可见,但在屏幕中占据空间(屏幕高度的一半)。
我的 XML 代码:
<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/coordinatorFriendProfil"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#81D4FA"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="@+id/fProfilAppBar"
android:layout_width="match_parent"
android:layout_height="250dp"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/fProfilCollapsing"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#B3E5FC"
android:gravity="center"
android:orientation="vertical"
app:contentScrim="#03A9F4"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<LinearLayout

<TextView

</LinearLayout>
<android.support.v7.widget.Toolbar
android:id="@+id/fProfilToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="@+id/fProfilContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
