Eclipse 不生成 MainActivity.java &活动_main.xml [英] Eclipse doesn't generate MainActivity.java & activity_main.xml

问题描述

在创建一个新的Android应用程序项目时，src文件夹&中应自动生成其包名下的MainActivity.javaactivity_main.xml 应该在 layout 文件夹中创建.但它没有被创建.

On creating a new Android Application Project, MainActivity.java under its package name should be generated automatically in src folder & activity_main.xml should be created inside layout folder. But it is not created.

而且在清单中它也不会生成这个 POC

And also in manifest it doesn`t generate this POC

 <activity
        android:name="info.androidhive.slidingmenu.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

但是，我手动添加了所有这些内容.

However, I added all these things manually.

• activity_main.xml 然后显示这个错误

• activity_main.xml then shows this error

 Eclipse is loading framework information and the layout library from the SDK folder.
 activity_main.xml will refresh automatically once the process is finished.

MainActivity.java 无法识别 setContentView(R.layout.activity_main)

昨天我从 SDK Manager 下载了更新，这些工具已安装/updated

And yesterday I downloalded the updates from SDK Manager these tools are installed /updated

我尝试清理项目，更改工作区，重新启动 eclipse &windows 但它没有帮助:(

I tried cleaning the project,changing the workspace,restarting the eclipse & windows but it doesn't helps :(

推荐答案

正如一个人所说

即使我下载了 Android SDK 并进行了全新安装，我也遇到了同样的问题，但我刚刚解决了它.我尝试单击帮助"->检查更新"，然后我收到一条弹出消息，说一切都是最新的，但经过进一步研究，我发现它不是最新的.您需要做的是单击帮助"->安装新软件"并从此网址安装(这将更新它):https://dl-ssl.google.com/android/eclipse/

I had the same problem even though I downloaded the Android SDK and did a clean install, but I just resolved it. I tried to click "Help" -> "Check for updates", and then I got a pop-up message saying everything was up to date, but after further research it appeared to me it wasn't up to date. What you need to do is click "Help" -> "Install new software" and install (this will update it) from this url: https://dl-ssl.google.com/android/eclipse/
