android - 将 CardView 移动到 NavigationView 下方

Question

我希望将卡片 View 向下移动，这样它就不会被导航栏挡住。这是显示我当前遇到的问题的屏幕截图:Nav-Bar Covering Cardview .任何建议，将不胜感激!

这是我的 activity_recycler_view XML 代码:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout

    tools:openDrawer="start">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                  android:orientation="vertical"

    <include layout="@layout/content_home"

这是我的 nav_header_home XML 代码:

<?xml version="1.0" encoding="utf-8"?>

尝试将您的布局编辑成这样:

activity_recycler_view.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

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

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_home"
        app:menu="@menu/activity_home_drawer" />

</android.support.v4.widget.DrawerLayout>
