Question

实际上我尝试过这样我可以将我的导航抽屉放在我的应用栏下面，同时还有标签和主要内容。我还必须为工厂提供协调器布局。帮助我，告诉我是否可以使用协调器布局我用于fab。

如果有人遇到同样的问题：关键是要替换

android.support.v4.widget.CoordinatorLayout

与

android.support.design.widget.CoordinatorLayout

标签名称中的

。例如：

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:fab="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:fitsSystemWindows="true">

这可能不是您问题的正确答案，但您可以尝试使用新的设计支持库在应用栏下方导航视图。

<?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/coordinatorLayout"
   android:layout_width="match_parent"
   android:layout_height="match_parent">


 <android.support.design.widget.AppBarLayout
        android:id="@+id/appBarLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

    <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"/>

    <android.support.design.widget.TabLayout
            android:id="@+id/tabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabTextColor="@android:color/white"
            app:tabSelectedTextColor="@android:color/white"
            app:tabIndicatorColor="@android:color/white"
            app:tabIndicatorHeight="6dp"/>

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

 <android.support.design.widget.FloatingActionButton
    android:id="@+id/floatingActionButton_ID"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end|bottom"
    android:layout_margin="16dp"
    android:src="@drawable/yourdiesiredicon"
    app:backgroundTint="@color/yourColor"
    app:fabSize="normal" />

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

希望我能帮助你。

将此行添加到build.gradle ...

 compile 'com.android.support:design:25.2.0'

扩展类android.support.v4.widget.CoordinatorLayout时出错
