Question

当我用导航抽屉给我的布局充气时，给布局充气有一个错误。这个布局中的问题是什么。如果有人可以，请帮助我。我在drawer_layout之间使用了navigation_view，但它无法正常工作并且在布局

时出错

activity_main.xml中

Answer 1

从app:actionViewClass="android.support.v7.widget.SearchView"和DrawerLayout移除属性CoordinatorLayout。
将menu和headerLayout添加到NavigationView。

更新activity_main.xml，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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.techweblearn.musicplayer.MainActivity"
    android:id="@+id/drawer_layout">

    <include layout="@layout/activity_main_view" />

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

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

更新activity_main_view.xml，如下所示：

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

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <android.support.v7.widget.Toolbar
            android:id="@+id/my_toolbar"
            style="@style/MyAppTheme"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center_vertical" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tab"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="top"
            android:background="#ffffff"
            app:tabIndicatorColor="@color/black" />

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

    <android.support.v4.view.ViewPager
        android:layout_marginBottom="?attr/actionBarSize"
        android:layout_marginTop="105dp"
        android:layout_below="@id/appBar"
        android:id="@+id/view_pager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentLeft="true">

    </android.support.v4.view.ViewPager>

    <RelativeLayout
        android:elevation="16dp"
        android:id="@+id/design_bottom_sheet"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ffffff"
        app:behavior_hideable="true"
        app:behavior_peekHeight="50dp"
        app:layout_behavior="@string/bottom_sheet_behavior">

        <fragment 
            android:name="com.techweblearn.musicplayer.BottomPlayer"
            android:id="@+id/bottom_fragment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

希望它有所帮助！

通过添加解决了错误。

app:itemTextColor="#000"

导航视图中的

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:menu="@menu/nav_menu_item"
    app:headerLayout="@layout/nav_header"
    app:itemTextColor="#000"/>

使用导航充气布局时出错
