Question

RecyclerView的最后一项与BottomNavigationView重叠。描述和时间与BottomNavigationView重叠。

framgment_news.xml：这包含我的RecyclerView

<android.support.constraint.ConstraintLayout ...
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Fragments.NewsFragment"
android:background="#fff">

<ImageView
    android:id="@+id/imageView" ... />

<TextView
    android:id="@+id/textView" ... />

<TextView
    android:id="@+id/textView3" ... />

<TextView
    android:id="@+id/textView2" ... />

<com.mikhaellopez.circularimageview.CircularImageView
    android:id="@+id/circularImageView" ... />

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="12dp"
    app:layout_constraintTop_toBottomOf="@+id/textView3"
    tools:layout_editor_absoluteX="0dp"
    android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>

activity_home.xml

<android.support.constraint.ConstraintLayout ...
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".HomeActivity">

    <FrameLayout
        android:id="@+id/frameContainer"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_marginStart="0dp"
        android:layout_marginTop="0dp"
        android:layout_marginEnd="0dp"
        app:layout_constraintBottom_toTopOf="@+id/view"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        android:layout_above="@+id/bottom_navigation_view"
        app:layout_constraintTop_toTopOf="parent" />

    <!--Border on Top of Bottom Navigation View-->
    <View
        android:id="@+id/view"
        android:layout_width="match_parent"
        android:layout_height="0.5dp"
        android:background="#616161"
        app:layout_constraintBottom_toTopOf="@+id/bottom_navigation_view" />

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/bottom_navigation_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#fff"
        app:labelVisibilityMode="unlabeled"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:menu="@menu/bottom_navigation_menu" />

</android.support.constraint.ConstraintLayout>

The last item of RecyclerView being overlapped by BottomNavigationView

Answer 1

将填充添加到RecyclerView的父布局

<android.support.constraint.ConstraintLayout ...
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="56dp"
    tools:context=".Fragments.NewsFragment"
    android:background="#fff">

并根据Material Design更改BottomNavigationView的高度

<android.support.design.widget.BottomNavigationView
    android:id="@+id/bottom_navigation_view"
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:background="#fff"
    app:labelVisibilityMode="unlabeled"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:menu="@menu/bottom_navigation_menu" />

Answer 2

您应该将加载片段的容器视图附加到底部导航视图的顶部。这样，如果您在容器视图中加载任何内容，它将不会位于底部导航视图下。

app:layout_constraintEnd_toEndOf="parent"

这部分代码应该在你的框架布局中

app:layout_constraintBottom_toTopOf="@+id/bottom_navigation_view"

只需使用您已有的约束布局，从框架布局中删除底部约束并将其附加到bottomNavigationView的顶部！

在activity_home.xml中，您可以使用RelativeLayout。并在FrameLayout中设置android:layout_above="@+id/bottom_navigation_view"。
