android - Android构建一个简单的用户界面错误

Question

我正在关注 android 应用程序教程，但我遇到了这个错误，谁能帮助我并告诉我我做错了什么？另外我正在使用 android 4.3。顺便说一句，我是 Stack Overflow 的新手，如果我做错了什么，很抱歉。

这是我的代码：

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

    <EditText android:id="@+id/edit_message"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:hint="@string/edit_message" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/button_send" />
</LinearLayout>

这是错误。

我认为您的 AndroidManifest.xml 文件存在一些重大问题。在堆栈跟踪中，可以看到以下错误。我在一些错误旁边添加了一些斜体注释。

不支持 XML 版本“4.3”，仅支持 XML 1.0。-应该是<?xml version="1.0"?>
不支持 XML 版本“1”，仅支持 XML 1.0。-见上文
XML 声明必须以“?>”结尾。-见上文
文档中根元素之后的标记必须格式正确。
元素类型“Button”必须由匹配的 end-tag 终止</Button>。-为什么你的清单文件中有一个按钮？
与元素类型“uses-sdk”关联的属性“android:minSdkVersion”的前缀“android”未绑定。-你可能会错过类似的东西xmlns:android="http://schemas.android.com/apk/res/android"
'=' 字符必须跟在 XML 声明中的“uses-sdk”之后。-你可能失踪了<uses-sdk android:minSdkVersion="7" />
XML 文档结构必须在同一个实体内开始和结束。

您能否发布清单文件的内容？
