浮动操作按钮和设计库膨胀错误答案

【问题标题】：Floating Action Button and design library inflation error浮动操作按钮和设计库膨胀错误
【发布时间】：2016-07-14 19:26:00
【问题描述】：

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

<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" />

在我的一个布局中出现此错误

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

这是我的主要活动 (it has navigation drawer)

public class MapNavActivity extends AppCompatActivity

如果我将AppCompatActivity 更改为Activity，我知道它应该可以工作

但是这对我不起作用。这是清单文件中定义的活动

<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>

我被这个问题困扰了将近 5 个小时。有谁知道如何解决这个问题？

编辑清单文件

我还会添加完整的异常

【问题讨论】：

请发布您的主要文件。
添加你的 androidmanifest
你需要 AppCompat ！将其添加到您的构建 gradle com.android.support:support-v4:24.0.0
我编辑了我的答案也添加了 appCompat 但是我仍然得到同样的异常
关于样式 AppTheme 继承自 Theme.AppCompat 还是他的孩子？

标签： android android-support-library android-theme floating-action-button android-inflate

【解决方案1】：

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' 在您的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。

【讨论】：

【解决方案2】：

好的，去简单的方法。

首先将依赖项添加到您的 build.gradle。

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'

}

然后打开您的 XML 文件并添加浮动操作按钮。

<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"
    android:src="@android:drawable/ic_dialog_email" />

然后打开您的 .java 文件并初始化浮动按钮

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Click action
          // write you code here.
        }
    });

然后清理您的项目并运行它。

我希望这个解决方案对您有所帮助。
