Xamarin - 二进制XML文件行＃1：错误充气类＆LT;＆不明GT; [英] Xamarin - Binary XML file line #1: Error inflating class <unknown>
问题描述
我目前正在开发中Xamarin的小Android应用程序，使用C＃。结果
下图显示了，当我在我的模拟器运行：结果
选择第一个选项卡时被调用code的这条线，这是在默认情况下，这意味着只要我运行程序时出现此错误。这似乎是导致错误的XML片段是这样的，在我的布局文件之一：
I am currently developing a small Android app in Xamarin, using C#.
The following shows up when I run it on my emulator:
This line of code is called when the first tab is selected, which is by default, meaning that this error occurs as soon as I run the program. The XML snippet which seems to be causing the error is this, in one of my layout files:
android:background="@color/done"
这是在线路Dialer.axml 111，其全部如下。在这里，我想引用一个颜色状态列表我按钮，这样取决于它是否被触摸与否的颜色变化。我知道这行导致错误，因为从按钮删除它标签，它在导致程序完美运行。下面是 done.xml 的code，在我的颜色文件夹：
This is in line 111 of Dialer.axml, the entirety of which is below. Here, I am trying to reference a color state list for my button, so that the color changes depending on whether it is being touched or not. I know that this line causes the error, because removing it from the button tag which it's in causes the program to run perfectly. Here is the code for done.xml, in my color folder:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:color="#ff2222ff"/>
<item android:state_pressed="true" android:state_enabled="false" android:color="#ff4444ff"/>
<item android:state_enabled="false" android:color="#ff000000"/>
<item android:color="#ff0000ff"/>
</selector>
这里是code为 Dialer.axml ：

是什么原因造成的错误？我在引用 done.xml 错误？难道我把它放在错误的文件夹？
What is causing the error? Am I referencing done.xml incorrectly? Did I place it in the wrong folder?
先谢谢了。
推荐答案
您done.xml是颜色状态列表，但颜色状态列表不能被用来作为背景。您需要使用状态列表抽拉背景。
Your done.xml is color state list but color state lists can not be used as backgrounds. You need to use state-list-drawable for background.
下面是你的颜色状态列表状态列表抽拉版本：
Here is the state-list-drawable version of your color state list:
<?xml version="1.0" encoding="UTF-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true">
<shape android:shape="rectangle">
<solid android:color="#ff2222ff" />
</shape>
</item>
<item android:state_pressed="true" android:state_enabled="false">
<shape android:shape="rectangle">
<solid android:color="#ff4444ff" />
</shape>
</item>
<item android:state_enabled="false">
<shape android:shape="rectangle">
<solid android:color="#ff000000" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#ff0000ff" />
</shape>
</item>
</selector>
将这个变成一个XML文件在您绘制的文件，使您的布局按钮这样的XML：
Put this into an xml file in your drawable file and make your layout button xml like this:
android:background="@drawable/done"
