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，但与此同时也创建了appcompat_v7。由于appcompat_v7有错误，现在我的项目无法运行。 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>

与描述

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

我曾尝试清理和重建项目，但错误仍然存​​在。如何解决此问题？

这是appcompat_v7-> res-> values-v21-> styles.xml此文件是第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

检查您的项目和appcompat中的构建目标。 您的项目不得小于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 2

其他人也有同样的问题，您需要安装Java 1.8

看到这个链接： https : //stackoverflow.com/a/26642124/2767703

Answer 3

当Android Lollipop启动时，eclipse和sdk管理器也进行了升级，但是

SDK 5.0（Lollipop）存在有关v7的问题（appcompat，cardview ...）-找不到资源或不匹配。

这个连结

在我的项目中使用android.support.v7.widget.CardView（Eclipse）

否则这对您有帮助

Answer 4

要解决此问题，

1. 右键单击appcompat_v7库，然后选择“属性”
2. 点击Android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appcompat_v7库下的project.properties文件，
6. 将项目目标设置为：target = android-21
7. 清理并构建appcompat_v7库和您的项目

看这里

Answer 5

右键单击appcompat项目文件夹，然后打开“属性”。 转到“ Android”部分，然后检查“ Android 5.0”，将其作为项目构建目标并享受它：)

Answer 6

希望这种方法对您有帮助。

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