工具栏在Kitkat上崩溃

Question

我的应用程序上有一个自定义工具栏，在kitkat设备上运行时似乎崩溃了。

我得到的错误是：

  

android.view.InflateException：二进制XML文件行＃9：错误膨胀类android.support.v7.widget.Toolbar

加载mainActivity时崩溃。

我的工具栏xml是：

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay"
    xmlns:app="http://schemas.android.com/apk/res-auto">


    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/toolbar_background"
        android:textAlignment="center"
        android:theme="@style/ToolBarStyle"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

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

我环顾四周，解决这个问题的唯一解决办法是因为我没有?attr标签。

崩溃于：

setContentView(R.layout.activity_main);

感谢任何帮助。

修改

我修复了工具栏问题，在我的coordinatorLayout中我只是包含了我的工具栏。现在，我们不再得到那个错误了。

但是我收到了一个新错误，

  

android.view.InflateException：二进制XML文件行＃16：错误膨胀类android.support.design.widget.NavigationView

Answer 1

AppBarLayout在很大程度上取决于在CoordinatorLayout中用作直接子项。如果您在不同的ViewGroup中使用AppBarLayout，那么它的大多数功能将无效。

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

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

     <!-- Your scrolling content -->

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

 <android.support.design.widget.AppBarLayout
         android:layout_height="wrap_content"
         android:layout_width="match_parent">

     <android.support.v7.widget.Toolbar
             ...
             app:layout_scrollFlags="scroll|enterAlways"/>

     <android.support.design.widget.TabLayout
             ...
             app:layout_scrollFlags="scroll|enterAlways"/>

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

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