bottomnavigationview隐藏屏幕后面的视图的某些部分。
如何在页脚上方显示视图(bottomnavigationview)
我已经编辑了下面的并更新了mainactivity.xml文件
另外,我添加了另一个xml的xml文件如下

我的一个xml

<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" >
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    android:id="@+id/refresh_layout"
    android:layout_width="match_parent"
    app:layout_constraintBottom_toTopOf="@id/bottom_navigation"
    android:layout_height="match_parent"

    android:background="@color/colorPrimary"
    tools:ignore="NotSibling,RtlHardcoded">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@null">
/>

使用约束布局并将约束设置为上根视图 app:layout_constraintBottom_toTopOf="@id/bottomNavigationView" .

<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" >

<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    android:id="@+id/refresh_layout"
    android:layout_width="match_parent"
    android:layout_height="0dp"      
    android:background="@color/colorPrimary"
    tools:ignore="NotSibling,RtlHardcoded"
     app:layout_constraintTop_toTopOf="parent" 
    app:layout_constraintBottom_toTopOf="@id/bottom_navigation">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@null">

</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

<com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/bottomNavigationView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:menu="@menu/bottom_nav_menu" />

</androidx.constraintlayout.widget.ConstraintLayout>
