android - "Error inflating class menu"- android.view.InflateException : Binary XML file line #119: Error inflating class menu

Question

我正在开发一款 Android 应用，我尝试在该应用中实现社交分享按钮。

我查看了 Android 文档以进行共享 - Sharing simple data并在那里实现代码；然而，应用程序在启动时崩溃并显示错误消息 android.view.InflateException: Binary XML file line #119: Error inflating class menu

我更改了布局文件的位置和约束但没有成功。

            android:id="@+id/menu_item_share"
            android:actionProviderClass="android.widget.ShareActionProvider"
            android:showAsAction="ifRoom"
            android:title="Share" />
    </menu>

我知道扩大社交分享菜单存在问题，但我不明白应用崩溃的原因；因此，我们将不胜感激任何帮助或提示!

Answer 1

"android.view.InflateException: Binary XML file line #119: Error inflating class menu"

你应该试试

app:showAsAction="ifRoom"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"

示例

<item android:id="@+id/menu_item_share"
    android:title="@string/share"
    app:showAsAction="ifRoom"
    app:actionProviderClass="android.support.v7.widget.ShareActionProvider"/>

阅读Use action views and action providers
