java - 如何修复API版本23的androidx中的FloatingActionButton膨胀错误？

我正在使用androidx创建基本目录应用程序。使用FloatingActionButton添加条目。
该应用程序可以在模拟器上完美运行，但是在我的手机上运行时会显示android.view.InflateException。

错误 -

FloatingActionButton XML(此代码来自错误的第26行。)-
 <com.google.android.material.floatingactionbutton.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="@drawable/ic_plus_white" />

MainActivity代码-
 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = findViewById(R.id.fab);

        fab.setOnClickListener(v -> addInformation());

我已经提到了很多解决方案，并且大多数人都在谈论将android:backgroundTint更改为app:backgroundTint，正如您所看到的，我什至没有使用。

我的build.gradle(Module: app)依赖项-
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.android.material:material:1.0.0'

    androidTestImplementation 'androidx.test:runner:1.2.0'

    annotationProcessor "androidx.lifecycle:lifecycle-compiler:$rootProject.archLifecycleVersion"

    //Gson
    implementation 'com.google.code.gson:gson:2.8.5'
}

我的styles.xml-
<resources>

    <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>

    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.MaterialComponents.Dark.ActionBar" />

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.MaterialComponents.Light" />

</resources>

ic_plus_white.xml-
<vector android:height="23dp"
    android:viewportHeight="512"
    android:viewportWidth="448"
    android:width="20dp"
    xmlns:android="http://schemas.android.com/apk/res/android">

</vector>

模拟器28上的API版本

移动版的API版本23

解决了:只需将我的可绘制ic_plus_white.xml从drawable-v-24文件夹移动到drawable文件夹。解决了这个问题!

最佳答案

请确保您的应用程序或 Activity 主题继承以下主题之一:

  • Theme.MaterialComponents
  • Theme.MaterialComponents.NoActionBar
  • Theme.MaterialComponents.Light
  • Theme.MaterialComponents.Light.NoActionBar
  • Theme.MaterialComponents.Light.DarkActionBar
  • Theme.MaterialComponents.DayNight
  • Theme.MaterialComponents.DayNight.NoActionBar
  • Theme.MaterialComponents.DayNight.DarkActionBar

    • 看来您的drawable/ic_plus_white不是有效的可绘制对象。请也验证其内容。
