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