android - 无法在 AVD Eclipse 中运行我的第一个 Hello World

Question

我正在尝试按照 This Link 上的教程进行操作我得到以下错误

[2012-10-03 22:02:16 - MyFirstApp] res\layout\activity_main.xml:0: error: Resource entry activity_main is already defined.

我的 activity_main.xml 中有以下代码

<?xml version="1.0" encoding="utf-8"?>

<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>

谁能告诉我出了什么问题。我花了很多时间试图解决这个问题。配置有问题吗？当我单击运行按钮时，会创建一个名为 activity_main.out.xml 的文件，该文件是空的。

您正在尝试运行 xml 文件 activity_main。将焦点更改为任何 java 文件或通过右键单击项目并运行它从包资源管理器运行它。在执行所有这些操作之前，请删除您的 activity_main.out 文件。
