Question

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。感谢。

<?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。

Answer 1

您的问题有简单的解决方案。这是根据marginBottom的文档FrameLayout将56dp放在height BottomNavigationView上。我不确定它是否可以根据移动屏幕进行调整。甚至文件也没有说明改变高度。我在一些应用程序中使用它，但我没有发现BottomNavigationView的高度正在发生变化。但以防万一检查。希望这会有所帮助。

将CoordinatorLayout和BottomNavigationView放置在RelativeLayout内

具有BottomNavigation android：layout_alignParentBottom =“ true”和上面的带有CoordinatorLayout布局的android：layout_above =“ @ + id / {BottomNavigationView-ID}”

请检查下面的布局

Answer 4

一个更好的解决方案，而无需对bottomView进行硬编码

您可以将其放置在ConstraintLayout中，并将内容的高度设置为0dp，并将其设置为bottomToTop =“ @ id / bottomViewId”或放置在bottomViewNavigator中的ID。

这里是一个例子。

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".StartActivity">

    <fragment
        android:id="@+id/nav_controller"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toTopOf="@id/bottom_navigation"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:defaultNavHost="true"
        app:navGraph="@navigation/nav_graph" />

    <com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        android:background="@color/colorPrimary"
        app:itemIconTint="@android:color/white"
        app:itemTextColor="@android:color/white"
        app:menu="@menu/bottom_navigation_menu" />
</androidx.constraintlayout.widget.ConstraintLayout>

Answer 5

将此行添加到您的BottomNavigationView中 android：background =“？android：attr / windowBackground”

<com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/app_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        app:labelVisibilityMode="labeled"
        android:background="?android:attr/windowBackground"
        app:menu="@menu/app_navigation" />
