当我在我的主题中添加背景项目时，BottomNavigationView 消失了。

@color/primary_red @color/primary_red

和底部导航视图

 <android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="match_parent"
        android:layout_height="60dp"
        android:layout_gravity="bottom"
        design:menu="@menu/bottom_menu_bar" />

当我从主题中删除背景项目时，它看起来像在此处输入图像描述

窗口和底栏之间有空白区域。而且背景文本也出现在前景中。如何删除它。

我正在使用此代码，它运行良好，请尝试在您的项目匹配时更改您的代码。

<android.support.design.widget.BottomNavigationView
android:id="@+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="@menu/navigation"/>
