Java 导航抽屉xml中的重叠活动布局
这是第一个应用程序I程序,我有以下问题:我的活动\u导航\u抽屉如下所示:Java 导航抽屉xml中的重叠活动布局,java,android,navigation,drawer,Java,Android,Navigation,Drawer,这是第一个应用程序I程序,我有以下问题:我的活动\u导航\u抽屉如下所示: <?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"

在这个xml文件中,我包含了我的appbar和我将在这个addbar下添加的内容。不幸的是,内容与整个appbar重叠(换句话说,我包含的两个布局是重叠的)
appbar.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="wrap_content"
tools:context="...NavigationDrawerActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
</RelativeLayout>
content.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="...NavigationDrawerActivity">
<include layout="@layout/activity_function_overview" />
</RelativeLayout>
我在这里做错了什么?在
appbar.xml
中,使用LinearLayout
作为根布局,使用垂直方向
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="wrap_content"
android:orientation="vertical"
tools:context="...NavigationDrawerActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<!-- Your content layout here -->
</LinearLayout>
仅供参考,您还可以使用android.support.design.widget.CoordinatorLayout来获得一些额外功能。您是指CoordinatorLayout而不是LinearLayout?是的,您也可以使用android.support.design.widget.CoordinatorLayout而不是LinearLayout
