在Android中出现“Error inflating class android.support.design.widget.FloatingActionButton”错误

当我尝试构建应用程序时，在FloatingActionButton中会显示android.view.InflateException错误？我真的不知道是什么导致了这个错误。

针对您的情况，问题出现在styles.xml文件中，您的基础主题名称为AppBaseTheme。请将其更改为AppTheme，因为您可以看到在Manifest文件中已经使用了AppTheme。

我列举了可能导致android.support.design.widget.FloatingActionButton类出问题的所有原因。请仔细阅读以下几点：

  1. FAB按钮是Design支持库组件。您的Activity必须扩展AppCompatActivity而不是Activity。

  2. 您的活动主题也应该是适当的Theme.AppCompat主题。同时FAB需要colorAccent，请确保您在styles.xml文件中有它们。

    3. <!-- Base application theme. -->
<style name="AppTheme" parent="Base.AppTheme">
<!-- Customize your theme here. -->
</style>

<style name="Base.AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:colorPrimary">@color/primary</item>
<item name="android:colorPrimaryDark">@color/primary_dark</item>
<item name="android:colorAccent">@color/accent</item>
</style>

  3. 使用 app:backgroundTint="@color/your_color" 替代 android:backgroundTint。

  4. 不要忘记在项目的 build.gradle 文件中添加 design 库。

    5. dependencies {
 compile 'com.android.support:appcompat-v7:23.1.1'
 compile 'com.android.support:design:23.1.1'
 ...
}

  5. 在 Extras > Android Support Repository 和 Android Support Library 中的 SDK 管理器上更新支持库。

希望它可以解决您的错误。

我的整个项目都出现了这个问题，FAB（浮动操作按钮）充气错误。刚才我在登录页面设计中将 FAB 注释掉了，但现在在另一个页面出现了错误。你是否遇到过类似的异常？ - MohanRaj S
不，Vishal，我只是重新使用我的旧代码并再次进行。现在这是一个很大的头痛。 - MohanRaj S
我已添加了样式和清单文件，请检查一下，感谢您的考虑。 - MohanRaj S

非常抱歉之前的回复，我测试了您的代码。问题出在您的styles.xml文件中，您的基础主题名称是AppBaseTheme。请将其更改为AppTheme，因为您可以看到在Mainfest文件中使用了AppTheme。 - Vishal Puri

如果你在API 21+上使用backgroundTint，那么只需在FloatingActionButton中使用此行代码(app而不是android)：

app:backgroundTint="@color/colorAccent"

这里是示例布局。
<?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:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        app:elevation="6dp"
        android:tint="#FFF"
        app:srcCompat="@drawable/ic_add_black_24dp" />

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