Question

我试图将Toolbar，TabBarLayout和BottomNavigationView添加到我的活动中。在不添加工具栏的情况下，一切正常，但是在添加工具栏后，应用程序崩溃并显示错误：

Android.Views.InflateException：二进制XML文件第1行：二进制XML 文件行＃1：错误夸大类 android.support.design.widget.BottomNavigationView

我正在使用LinearLayout。我尝试通过更改layout_weight和theme以及我可以在stackoverflow上找到的所有其他方法或通过搜索Google进行尝试，但是找不到解决方案。我正在分享布局，样式和活动代码。

activity_main.axml

dataGridView1.DataSource = results;

    <item name="colorPrimary">@color/yellow</item>
    <item name="colorPrimaryDark">@color/black</item>
    <item name="colorAccent">@color/white</item>
  </style>
</resources>

有人可以帮我吗？

Answer 1

从包括标记中删除ID属性：android:id="@+id/toolbar"。它应该看起来像这样
```
layout="@layout/toolbar_layout" />
```
您的ToolbarLayout文件名不正确，应该是这样的：toolbar_layout不带大写字母。

发布问题后，我仍然尝试解决问题。我清除了解决方案，然后重新启动Visual Studio。然后我清除了项目，然后再次重新启动Visual Studio，然后一切正常。
