CoordinatorLayout + AppBarLayout + NavigationDrawer [英] CoordinatorLayout + AppBarLayout + NavigationDrawer

问题描述

将CoordinatorLayout与AppBarLayout和NavigationDrawer组合时，我遇到布局问题.

I have a layouting problem when combining CoordinatorLayout with an AppBarLayout and a NavigationDrawer.

问题在于，NavigationDrawer及其内容隐藏在工具栏的后面.我已经做了很多研究，并尝试了很多重组，但是没有一个解决方案"可以解决我的问题.

The problem is, that the NavigationDrawer and it's content are hidden behind the toolbar. I have already did a lot of research and tried a lot of restructuring, but none of the "solutions" fixed my issue.

基本样式为Theme.AppCompat.Light.NoActionBar.

推荐答案

您的CoordinatorLayout正在包装DrawerLayout和NavigationView，这意味着Coordinator可以控制所有内容的布局方式.您需要将协调器嵌套在抽屉中，如下所示:

Your CoordinatorLayout is wrapping your DrawerLayout and NavigationView, which means the Coordinator is in control of how everything is laid out. You need to nest the Coordinator inside the drawer, like so:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clickable="true"
    android:focusableInTouchMode="true">

    <android.support.design.widget.CoordinatorLayout
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/overview_coordinator_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">


            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimaryDark"
                app:layout_scrollFlags="enterAlways|scroll" />

        </android.support.design.widget.AppBarLayout>

        <android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="@string/lorem_ipsum_long" />

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

        <android.support.design.widget.FloatingActionButton
            android:id="@+id/overview_floating_action_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="16dp"
            android:clickable="true"
            android:src="@drawable/ic_add"
            app:layout_anchor="@id/overview_coordinator_layout"
            app:layout_anchorGravity="bottom|right|end"
            app:layout_behavior="@string/fab_onscroll_behavior" />

    </android.support.design.widget.CoordinatorLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/nvView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@android:color/white"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/navigationdrawer_main" />

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

那应该解决它！
