ImageButton 膨胀类错误

androidandroid-resourcesandroid-imagebuttoninflate-exceptionbinary-xml
9

我有一个应用程序，其中包含片段和图像按钮。问题是它在5.0及以上版本上运行正常，但在5.0以下版本上无法正常工作。最小SDK版本为17。

不知道这里出了什么问题。我得到了两个异常。

第一个是image button的RuntimeException。 第二个是fab选择器文件的ResourceNotFoundException。

日志： 第一个异常--

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.siddhi.timetablelayout/com.example.siddhi.timetablelayout.MainActivity}: android.view.InflateException: Binary XML file line #16:

错误膨胀类ImageButton

第二个异常--

Caused by: android.view.InflateException: Binary XML file line #16: Error inflating class ImageButton

在此行：

View view = inflater.inflate(R.layout.fragment_main, container, false); 主要片段。

抱歉，我无法查看您编辑后的问题。请提供原始文本以便我进行翻译。 - Sid
请问您能否检查一下哪个文件夹包含 fab_selector？ - Mustansar Saeed
它的drawable文件夹。@MustansarSaeed - Sid
你的@animator/fab_elevation_selector是什么？ - KDeogharkar
这是一个用于fab动画的xml文件。@KDeogharkar - Sid

表明在fab_selector中的<solid android:color="?attr/colorAccent" />是罪魁祸首。请尝试将color更改为HEX value再进行测试。

希望这可以帮到你。

可能情况是，Post Lollipop API 处理这些操作，但 Pre-Lollipop 不包含这些函数。只是一个猜测 :) - Mustansar Saeed
这并不是一个真正的“答案”。如果定义了主题属性，应该可以像所示那样使用它。 - Doug Stevenson
但是，当主题更改时，我如何更改fab的颜色？如果我提供十六进制值，它不会改变，对吧？@Mustnsar Saeed - Sid
@DougStevenson：Sid可以确认是否解决了他的问题。 - Mustansar Saeed
很好，这起作用了...但我不明白如何使用不同的资源文件？Fab选择器只有一个，如果我有三个主题，则有三种不同的强调颜色...如何应用到这里？@MustansarSaeed - Sid

是的，您需要创建一个名为“drawable-v21”的文件夹。

我也遇到了这个问题，但是我解决了它。

在我的情况下，错误是由于我导入的ImageButton图像被Android Studio自动保存在drawable-v24文件夹中。我从那里复制了png文件并将其粘贴到drawable文件夹中。

图片.png的格式不正确。 我的解决方案： 我在我的电脑上安装了Greenshot来截取屏幕上的图像 https://getgreenshot.org/ 然后我将图像保存为png文件放在我的res/drawable目录下。 这对我起作用了

这是谷歌上的一项顶级结果，我想分享一下我解决了相同错误的方法（虽然不是与上面完全相同的问题）

  • 确保构建工具版本是最新的
  • 我使用了vector src drawable和elevation value的组合（仅适用于API 21+），似乎会导致问题。我为v21制作了一个单独的布局以拥有elevation值（但在任何地方都保留了vector drawable），这对我解决了问题。

我解决了我的问题（rounded_corner_image_view.xml (v24)）：

android:background="@drawable/rounded_corner_image_view"

我的背景drawable是v24。创建了一个更低级的drawable，就完成了。
