问题描述

我已经在Android应用程序中实现了底部导航视图.带有五个片段.但是,我遇到一个问题,每次更改片段时,片段的内容都会与工具栏重叠.

I have implemented a bottom navigation view in my android application. With five fragments. However, I have a problem that each time I change the fragment the content of the fragment overlaps the toolbar.

底部导航视图的布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".DashboardActivity">

    <include layout="@layout/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </include>

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_above="@+id/navigationView"
        android:layout_height="match_parent"


       />

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/navigationView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="0dp"
        android:layout_marginStart="0dp"
        android:background="?android:attr/windowBackground"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:itemBackground="@android:color/white"
        app:itemIconTint="@color/cardview_dark_background"
        app:itemTextColor="@android:color/black"
        app:menu="@menu/navigation_menu"
        />
</android.support.constraint.ConstraintLayout>

其中一个片段布局的示例

    </android.support.v7.widget.CardView>

</android.support.constraint.ConstraintLayout>

这是内容重叠的屏幕外观

This is what the screen look like with overlapping content

推荐答案

在容器中添加边距:

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_above="@+id/navigationView"
    android:layout_height="match_parent"
    android:layout_marginBottom="{bottom_navigation_height}"
    android:layout_marginTop="{tool_bar_height}"

   />
