【中文标题】膨胀类 com.google.android.material.slider.Slider 时出错【英文标题】：Error inflating class com.google.android.material.slider.Slider 【发布时间】：2021-07-10 20:19:48 【问题描述】：我想膨胀一个包含单个 seekBar 的布局。通过这种方式，我创建了一个扩展片段类的 java 类，然后我膨胀了布局。但出现以下错误：
二进制 XML 文件第 9 行：二进制 XML 文件第 9 行：
warming.XML is in the following:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_
android:layout_>
<com.google.android.material.slider.Slider
android:layout_
android:layout_
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
android:layout_marginStart="42dp"
android:layout_marginTop="217dp"
android:layout_marginEnd="42dp"
android:layout_marginBottom="349dp"
android:valueFrom="0"
android:valueTo="300"
app:activeTrackColor="#ff4500"
app:inactiveTrackColor="#fbb999" >
</com.google.android.material.slider.Slider>
</RelativeLayout>
和 firstPage.java 膨胀布局 warm.XML 如下：
public class firstPage extends Fragment
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState)
return inflater.inflate(R.layout.warming,container,false);
使用下面的代码，我想执行 firstPage.java 类：
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new firstPage()).commit();
怎么了？谁能帮我？我在 *** 和其他一些网站上搜索过这个问题，也有类似的问题，但没有人能解决我的问题。

如果你想问我“为什么不使用“material:1.3.0”版本”，我可以说由于与导航抽屉布局相关的渲染问题，根据 *** 中的一些说明，我将其更改为“材料：1.2.0-alpha02”并解决了渲染问题。 我在另一篇文章中问了这个问题。您可以在以下链接中访问该问题： https://***.com/questions/67095956/com-google-android-materialmaterial1-2-0-alpha02-does-not-include-some-instr
这里是 Theme.xml：
<resources xmlns:tools="http://schemas.android.com/tools">
<!-- Base application theme. -->
<style name="Theme.MyApplication" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">@color/purple_200</item>

【问题讨论】：
发布完整的堆栈跟踪 @Gabriele Mariotti 添加了完整的堆栈跟踪。提前谢谢你。 您使用的是 1.3.0 吗？你的应用主题是什么？ @Gabriele Mariotti 不，我使用的是 1.2.0-alpha02 版本。 至少使用稳定版本 1.2.0 或 1.2.1 【参考方案1】：我创建了以下主题：
<style name="MyMaterialTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Add attributes here -->
<item name="colorPrimary">@color/itimalia_pink_califoria</item>
</style>
然后：
<com.google.android.material.slider.Slider
android:id="@+id/slider"
android:layout_
android:layout_
android:theme="@style/MyMaterialTheme"/>
它有效。
【讨论】：
【参考方案2】：好吧，经过大量搜索，我终于发现在android studio中有一个名为的滑块的类似对象。因此，您可以使用此对象而不是“滑块”对象。所以这种方式不会出现充气错误。
【讨论】：
【参考方案3】：您必须使用 app:trackColorActive 和 app:trackColorInactive 而不是
app:activeTrackColor 和 app:inactiveTrackColor:
<com.google.android.material.slider.Slider
...
app:trackColorActive="#ff4500"
app:trackColorInactive="#fbb999"/>
【讨论】：
当我替换你的代码并运行我的应用程序时，我的应用程序没有被执行，它也没有给出任何错误。但是当我从 warm.XML 中删除提到的 XML 代码时，我得到了同样的错误。还是谢谢你。【参考方案4】：我遇到了同样的问题。升级到 com.google.android.material:material:1.4.0 没有帮助。如上所述，唯一的解决方案是将android:theme 设置为某个值，然后它就起作用了。
【讨论】：
【参考方案5】：这是由于您的基本应用主题不是材料主题的子主题。就我而言，我使用的是 Appcompat child 的应用程序主题..但我使用的视图继承了 MaterialComponenets 主题的所有内容。它正在抛出错误。
应用主题：
<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
...
</style>
所以我创造了另一种风格，
<style name="WD_Slider" parent="Theme.MaterialComponents.DayNight.NoActionBar">
...
</style>
并在滑块视图中将该样式称为，
android:theme="@style/WD_Slider"
使用这种方法，您可以使用任何不属于您的应用主题的子视图，并在您在 XML 视图级别使用它时准确地覆盖所需的主题。
