android - float 操作按钮和设计库膨胀错误

Question

我正在使用设计支持库

defaultConfig {
        vectorDrawables.useSupportLibrary = true
        ...
}

dependencies {
    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support:support-v4:23.4.0'
    ...
}

当我添加 FloatingActionButton 时

<android.support.design.widget.FloatingActionButton
    android:layout_gravity="right"
    android:layout_margin="20dp"
    android:tint="#fff"
    android:src="@drawable/ic_menu_manage"
    app:backgroundTint="#b3000000"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

我的一个布局出现了这个错误

Caused by: java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library.

这是我的主要 Activity (它有抽屉导航)

public class MapNavActivity extends AppCompatActivity

我知道如果我将 AppCompatActivity 更改为 Activity 应该可以工作

但是这对我不起作用。这是 list 文件中定义的 Activity

<activity
    android:name=".MapNavActivity"
    android:label="@string/title_activity_map_nav"
    android:theme="@style/AppTheme.NoActionBarMain" />

这是 styles.xml 文件中的主题

<style name="AppTheme.NoActionBarMain" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

我被这个问题困了将近 5 个小时。有谁知道如何解决这个问题？

编辑 list 文件

我还将添加完整的异常(exception)

我刚刚在一个新项目中尝试了您的代码，它在我的机器上运行良好。确保 compile 'com.android.support:appcompat-v7:23.4.0' 位于您的 build.gradle 文件中，然后进行重建，看看是否有帮助。还要检查您的 SDK 管理器，看看您是否有任何尚未安装的旧更新。
