错误膨胀 class com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
Error inflating class com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
虽然有类似的问题，但是没有给我解决办法。当我尝试使用 com.google.android.material.floatingactionbutton.FloatingActionButton 时，它运行良好。但是如果我尝试使用 com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton，它会出错。
我在 XML 文件中的代码：
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:id="@+id/book_profile_write_review"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:contentDescription="@string/author_name"
android:text="@string/book_name"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:srcCompat="@drawable/ic_launcher_foreground" />

你能帮帮我吗？
您需要使用来自 Theme.MaterialComponents.
的应用程序或 activity theme
trace中可以看到：
Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).
来自你的logcat
Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).
因此，为您的 app/current 添加一个 material 主题 activity 将解决此问题
1) 添加依赖*（最新/更稳定的版本）
implementation 'com.google.android.material:material:1.2.0-alpha01'
2) 创建新主题
<style name="MyMaterialTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Add attributes here -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="textAppearanceButton">@style/AppTextAppearance.Button</item>
</style>
<!--To fix rendering in preview -->
<style name="AppTextAppearance.Button" parent="TextAppearance.MaterialComponents.Button">
<item name="android:textAllCaps">true</item>
</style>
根据您更改父 material 主题 parent="Theme.MaterialComponents.*
3) 更改应用主题或清单中的当前 activity 主题
android:theme="@style/MyMaterialTheme"
或
<activity android:name=".MyActivity"
android:theme="@style/MyMaterialTheme"> </activity>
4) 如果您在预览中发现任何渲染问题，将主题添加到 ExtendedFloatingActionButton 将解决此问题
Failed to find '@attr/textAppearanceButton' in current theme.
为 ExtendedFloatingActionButton 添加主题 android:theme="@style/MyMaterialTheme"
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:theme="@style/MyMaterialTheme"
android:text="ExtendedFab"
app:icon="@drawable/ic_add_a_photo_white_24dp"
/>
有关详细信息，请访问 Material Design Page
这个对我有用
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton android:theme="@style/MyMaterialTheme" .................. />
<style name="MyMaterialTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Add attributes here -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="textAppearanceButton">@style/AppTextAppearance.Button</item>
</style>
AndroidManifest.xml
Update your app theme to inherit from one of these themes, e.g.:
<style name="Theme.MyApp" parent="Theme.MaterialComponents.DayNight">
<!-- ... -->
</style>
build.gradle
dependencies {
// ...
implementation "com.google.android.material:material:1.3.0-alpha03"
