使用 androidX 在项目中配置 ViewPager2
ViewPager2 config in project using androidX
我的项目 运行 很好，没有在我的应用程序中实现 ViewPager2 gradle。但是当我在我的项目中使用它的 gradle implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01' 时，它给了我这个 Log-cat 错误...

现在可以使用了。
我的问题是
如果我删除 support:appcompat，我将无法使用 AppCompatActivity 及其用途。它存在于我现有的应用程序中。
如何解决？
如何同时使用 ViewPager2 和 support:appcompat？

我找到了解决方案。
正如@Kishore 和@Shweta 所说，迁移项目中的 AndroidX 是解决方案。
手动添加 android.useAndroidX=true 和 android.enableJetifier=true 让我很难过。因为它抛出一些错误或 Suggestion: add 'tools:replace="android:appComponentFactory"' to <application>
要在项目中启用 Jet-fire，android Studio 中有一个选项
Select 你的项目 ---> 右击
app----> 重构----> 迁移到 AndroidX
如下图所示：-
点击迁移到 AndroidX 后。
它将要求确认并备份您的项目。
最后一步它会要求您进行重构。
重构后检查你的 gradle.properties 有 android.useAndroidX=true 和 android.enableJetifier=true。如果不是，则将这两行添加到您的 gradle.properties 文件中：
android.useAndroidX=true
android.enableJetifier=true
