以下是我的布局xml.现在的问题是BottomNavigationView与FrameLayout重叠.我希望FrameLayout延伸到BottomNavigationView的顶部.

我尝试使用技巧,例如在FrameLayout中添加paddingBottom,但我想知道是否还有其他更好的解决方案.谢谢.

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <include layout="@layout/user_app_bar"/>

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="?android:attr/windowBackground"
        app:menu="@menu/navigation"
        app:itemTextColor="@color/colorPrimaryDark"
        app:itemIconTint="@color/colorPrimaryDark"
        />

    <FrameLayout
        android:id="@+id/fragment_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="58dp"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

   <android.support.design.widget.FloatingActionButton
       android:id="@+id/fab"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_margin="@dimen/fab_margin"
       app:layout_anchorGravity="bottom|end"
       app:layout_anchor="@id/app_bar"
       app:srcCompat="@drawable/ic_edit_white_24px" />

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

更新:有关user_app_bar.xml的更多信息.它包含一个CollapsingToolbarLayout.

<?xml version="1.0" encoding="utf-8"?>

    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay"
    app:layout_behavior="co.domain.DisableAppBarLayoutBehaviour"

    <android.support.design.widget.CollapsingToolbarLayout

        android:fitsSystemWindows="true"
