eclipse中的appcompat_v7错误

Question

我是 android 开发的新手。我创建了一个新项目，但同时也创建了 appcompat_v7。现在我的项目无法运行，因为 appcompat_v7 有错误。 该错误仅在以下行的appcompat_v7-> res-> values-v21-> style_base.xml中

<style name="Base.Widget.AppCompat.ActionButton"
           parent="android:Widget.Material.ActionButton">
  </style>

有说明

Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.ActionButton'

我已尝试清理和重建项目，但错误仍然存​​在。如何解决此问题？

这里是 appcompat_v7 -> res -> values-v21 -> styles.xml 该文件是第 75 行出现错误的文件： 错误：

<style name="Base.Widget.AppCompat.ActionButton"
           parent="android:Widget.Material.ActionButton">
    </style>

这是文件

Answer 1

别人也有同样的问题，你需要安装Java 1.8

查看此链接：https://stackoverflow.com/a/26642124/2767703

Answer 2

检查您的项目和 appcompat 中的构建目标。您的项目不得低于 appcompat 的目标，我认为需要 SDK 10 或更高版本：

在 Eclipse 中转到 Project->Properties->Android (Project Build Target)

Answer 3

Android Lollipop 启动后，eclipse 和 sdk manager 也升级了，但是

SDK 5.0(Lollipop) 存在关于 v7 (appcompat, cardview ...) 的问题 - 未找到资源或匹配。

或者这会帮助你

Answer 4

为了解决这个问题，

1. 右键单击 appcompat_v7 库并选择属性
2. 点击安卓选项，
3. 将项目构建路径设置为 Android 5.0（API 级别 21）
4. 应用更改。
5. 转到 project.properties appcompat_v7 库下的文件，
6. 将项目目标设置为：target=android-21
7. 清理 + 构建 appcompat_v7 库和您的项目

见here

Answer 5

右键单击 appcompat 项目文件夹并打开“属性”。 转到“Android”部分并选中“Android 5.0”作为项目构建目标 应用它并享受:)

Answer 6

希望这种方法对您有所帮助。

将appcompat v7的project.properties文件更新为：target=android-19为target=android-23。 始终以更高版本为目标。
