膨胀类 com.google.android.material.slider.Slider 时出错

Question

我想膨胀包含单个搜索栏的布局。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：

\n

二进制 XML 文件第 #9 行：二进制 XML 文件第 #9 行：膨胀类 com.google.android.material.slider.Slider 时出错

\n

warming.XML is in the following:\n\n    <?xml version="1.0" encoding="utf-8"?>\n<RelativeLayout\n    xmlns:android="http://schemas.android.com/apk/res/android"\n    xmlns:app="http://schemas.android.com/apk/res-auto"\n    android:layout_width="match_parent"\n    android:layout_height="match_parent">\n\n    <com.google.android.material.slider.Slider\n        android:layout_width="327dp"\n        android:layout_height="37dp"\n        android:layout_alignParentStart="true"\n        android:layout_alignParentTop="true"\n        android:layout_alignParentEnd="true"\n        android:layout_alignParentBottom="true"\n        android:layout_marginStart="42dp"\n        android:layout_marginTop="217dp"\n        android:layout_marginEnd="42dp"\n        android:layout_marginBottom="349dp"\n        android:valueFrom="0"\n        android:valueTo="300"\n        app:activeTrackColor="#ff4500"\n        app:inactiveTrackColor="#fbb999" >\n\n    </com.google.android.material.slider.Slider>\n</RelativeLayout>\n

\n

和firstPage.java 膨胀布局warming.XML 如下：

\n

public class firstPage extends Fragment {\n   @Nullable\n   @Override\n   public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {\n      return inflater.inflate(R.layout.warming,container,false);\n   }\n}\n

\n

使用以下代码，我想执行firstPage.java类：

\n

getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new firstPage()).commit();\n

\n

怎么了？谁能帮我？我在StackOverflow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。

下面是Build.gradle代码：

\n

plugins {\n    id \'com.android.application\'\n}\n\nandroid {\n    compileSdkVersion 30\n\n    defaultConfig {\n        applicationId "com.example.myapplication"\n        minSdkVersion 22\n        targetSdkVersion 30\n        versionCode 1\n        versionName "1.0"\n\n        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"\n    }\n\n    buildTypes {\n        release {\n            minifyEnabled false\n            proguardFiles getDefaultProguardFile(\'proguard-android-optimize.txt\'), \'proguard-rules.pro\'\n        }\n    }\n    compileOptions {\n        sourceCompatibility JavaVersion.VERSION_1_8\n        targetCompatibility JavaVersion.VERSION_1_8\n    }\n}\n\ndependencies {\n\n    implementation \'androidx.appcompat:appcompat:1.2.0\'\n    implementation \'com.google.android.material:material:1.2.0-alpha02\'\n//    implementation \'com.google.android.material:material:1.3.0\'\n    implementation \'androidx.constraintlayout:constraintlayout:2.0.4\'\n//    implementation \'com.android.support:design:28.+\'\n//    implementation \'com.google.android.material:material:1.3.0\'\n    testImplementation \'junit:junit:4.+\'\n    androidTestImplementation \'androidx.test.ext:junit:1.1.2\'\n    androidTestImplementation \'androidx.test.espresso:espresso-core:3.3.0\'\n}\n

\n

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 StackOverFlow 中的一些说明，我更改了它到“材质：1.2.0-alpha02”并解决了渲染问题。\n我在另一篇文章中问了这个问题。您可以通过以下链接访问该问题：\n /sf/ask/4696716951/

\n

这是 Theme.xml：

\n

<resources xmlns:tools="http://schemas.android.com/tools">\n<!-- Base application theme. -->\n<style name="Theme.MyApplication" parent="Theme.MaterialComponents.DayNight.DarkActionBar">\n    <!-- Primary brand color. -->\n    <item name="colorPrimary">@color/purple_200</item>\n    <item name="colorPrimaryVariant">@color/purple_700</item>\n    <item name="colorOnPrimary">@color/black</item>\n    <!-- Secondary brand color. -->\n    <item name="colorSecondary">@color/teal_200</item>\n    <item name="colorSecondaryVariant">@color/teal_200</item>\n    <item name="colorOnSecondary">@color/black</item>\n    <!-- Status bar color. -->\n    <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>\n    <!-- Customize your theme here. -->\n</style>\n

\n\n

Answer 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_width="0dp"
    android:layout_height="wrap_content"
    android:theme="@style/MyMaterialTheme"/>

它有效。

Answer 2

如果您的应用程序主题不是源自 Material Design，您可以通过将以下主题分配给 Slider 小部件来避免运行时崩溃。

android:theme="@style/Theme.MaterialComponents.DayNight.NoActionBar"

Answer 3

好吧，经过大量搜索，最后我发现 android studio 中有一个名为 <androidx.appcompat.widget.AppCompatSeekBar> 的类似滑块对象。因此，您可以使用此对象代替“滑块”对象。所以这种方式不存在膨胀错误。

Answer 4

这是因为您的基本应用程序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。它抛出了错误。

应用主题：

<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
   ...
</style>

所以我创建了另一种风格，

<style name="WD_Slider" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    ...
</style>

并将滑块视图中的样式称为，

android:theme="@style/WD_Slider"

通过这种方法，您可以使用不属于应用程序主题子级的任何视图，并在视图级别在 XML 中使用它时准确地覆盖所需的主题。
