我的项目运行良好，但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 gradleimplementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'时，它​​给了我这个 Log-cat 错误......

与此相同的错误implementation group: 'androidx.viewpager2', name:'viewpager2', version: '1.0.0-alpha01'

然后我创建了另一个空项目并实施implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'

它给了我这个错误.....

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
    is also present at [androidx.core:core:1.1.0-alpha04] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.

android.support.v4.app.CoreComponentFactory上面的错误具体是implementation 'com.android.support:appcompat-v7:28.0.0'和之间存在冲突implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'。所以我support:appcompat从我的项目中删除了这个库。

它现在正在工作。

我的问题是

如果我删除support:appcompat我不能使用 AppCompatActivity 及其用途。这存在于我现有的应用程序中。

如何解决这个问题？

我怎样才能同时使用ViewPager2呢support:appcompat？

编辑

@ManoharReddy 添加清单的tools:replace="android:appComponentFactory"内部<application>标记后。它给了我这个错误

我找到了解决方案。

正如@Kishore 和@Shweta 告诉在项目中迁移AndroidX 是解决方案。

手动添加android.useAndroidX=true并android.enableJetifier=true给我带来困难。因为它会抛出一些错误或 Suggestion: add 'tools:replace="android:appComponentFactory"' to <application>

要在项目中启用 Jet-fire，在 android Studio 中有一个选项

选择您的项目--->右键单击

应用---->重构---->迁移到AndroidX

如下图所示：-

在此处输入图像描述

点击Migrate to AndroidX后。

它将要求您确认并备份您的项目。

在此处输入图像描述

最后一步，它会要求您进行重构。

在此处输入图像描述

做重构后检查你的 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

感谢所有用户的帮助。
