Eclipse不产生MainActivity.java和放大器; activity_main.xml [英] Eclipse doesn't generate MainActivity.java & activity_main.xml

问题描述

在创建一个新的Andr​​oid应用程序项目， MainActivity.java 根据其包名应自动在的src 文件夹和放大器产生的; activity_main.xml 应在布局文件夹中创建。但它不是创建。

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.

和还体现它不`吨产生这个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>

不过，我手动添加这些东西。

However, I added all these things manually.

• activity_main.xml则显示此错误

• 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无法识别的setContentView（R.layout.activity_main）布局领域

和昨天我downloalded从 SDK管理器更新这些工具安装/更新

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

我试图清理项目，改变了工作区，重新启动日食和放大器;窗户，但它并没有帮助：（

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

推荐答案

正如有人所说

我有同样的问题，即使我下载了Android SDK和做一个干净的安装，但我只是解决了它。我试着点击帮助 - >检查更新，然后我得到了一个弹出消息说，一切是最新的，但经过进一步研究它似乎对我来说是不是最新的。你需要做的是点击帮助 - >安装新软件，并安装（这将更新）从这个网址： 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/
