android – CoordinatorLayout AppBarLayout NavigationDrawer

当CoordinatorLayout与AppBarLayout和NavigationDrawer组合时,我有一个布局问题。

问题是,NavigationDrawer及其内容隐藏在工具栏后面。我已经做了大量的研究,尝试了很多重组,但是没有一个“解决方案”解决了我的问题。

在这个小型Webm视频中可以看到演示:https://goo.gl/yWj3VM

基础风格是Theme.AppCompat.Light.NoActionBar。

我的activity_overview.xml如下所示:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    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.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clickable="true"
        android:focusableInTouchMode="true">

        <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.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>


    <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>
您的CoordinatorLayout正在包装您的DrawerLayout和NavigationView,这意味着协调员可以控制一切如何布局。您需要将协调员嵌入抽屉中,如下所示:

<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>

应该整理出来!
