In "android-support-v7-appcompat" project:

在“android-support-v7-appcompat”项目中：

• Delete “android-support-v7-appcompat” from Package explorer.
• Import again and check “Copy into workspace”
• In Properties -> Android -> in Project build target, uncheck Android 2.2 and check Android 4.1.2
• In Java build path, uncheck if you have any .jar library, and uncheck the Dependences

• 从包浏览器中删除“android-support-v7-appcompat”。
• 再次导入并勾选“复制到工作区”
• 在 Properties -> Android -> 在 Project build target 中，取消选中 Android 2.2 并选中 Android 4.1.2
• 在 Java 构建路径中，取消选中是否有任何 .jar 库，并取消选中依赖项

In other hand, the project that uses “android-support-v7-appcompat”:

另一方面，使用“android-support-v7-appcompat”的项目：

• In Properties -> Android add the library, but uncheck "IsLibrary”.
• In Android -> Project build tarjet check Android 4.0.
• In "Java Build Path" -> Order and Export -> Unchecked the .jar library
• Finally do a “Project -> Clean” both projects

• 在属性 -> Android 添加库，但取消选中“IsLibrary”。
• 在 Android -> Project build tarjet 检查 Android 4.0。
• 在“Java Build Path” -> Order and Export -> 取消选中 .jar 库
• 最后做一个“项目->清理”这两个项目

If you are using Gradle, then you have a problem with the latest version of the compatibility library.

如果您使用的是 Gradle，那么您在使用最新版本的兼容性库时会遇到问题。

If you have the following in your build.gradlefile with a '+'at the end:

如果您的build.gradle文件中有以下内容，并以 a'+'结尾：

dependencies {
    compile 'com.android.support:appcompat-v7:+'
}

then it may be grabbing a later version of the library than you want.

那么它可能会抓取比您想要的更高版本的库。

Changing the dependency to:

将依赖更改为：

dependencies {
    compile 'com.android.support:appcompat-v7:18.0+'
}

may fix your problem.

可能会解决您的问题。

In your app dependencies file check if you have the dependency

在您的应用程序依赖项文件中检查您是否有依赖项

compile 'com.android.support:appcompatv[anything here]

or

或者

implement 'com.android.support:appcompat[anything here]

delete or comment them out, click on the "lightbulb" for auto-suggestions and choose add a library dependency. clicking on the autofillbulb for appcompat

删除或注释掉它们，单击“灯泡”进行自动建议，然后选择添加库依赖项。 单击 appcompat 的 autofillbulb

Scroll the options for the first version of appcompat. The library will be added below the list of dependencies. Rebuild the app or invalidate caches and restart

滚动第一版 appcompat 的选项。该库将添加到依赖项列表下方。重建应用程序或使缓存无效并重新启动

In one case this has not worked and going to the folder containing the project, deleting the .gradle file and restarting Android Studio has worked. Got from Sneh Pandya's answer in https://reformatcode.com/code/android/error-while-gradle-sync

在一种情况下，这不起作用，转到包含项目的文件夹，删除 .gradle 文件并重新启动 Android Studio 已起作用。来自 Sneh Pandya 在https://reformatcode.com/code/android/error-while-gradle-sync 中的回答

1. Go to your project directory (or to Project View)
2. Find and open .idea directory
3. Remove caches and libraries directories <-- this is essential
4. Invalidate Caches / Restart

1. 转到您的项目目录（或项目视图）
2. 查找并打开 .idea 目录
3. 删除缓存和库目录 <-- 这是必不可少的
4. 使缓存无效/重新启动
