感谢这个主题,我能够在Windows上的Eclipse中为我的Android项目提供Javadoc链接.具体来说,"{@link android.widget.Toast}"目前已转换为" http://d.android.com/reference/android/widget/Toast.html?is-external=true " 的链接.我用Javadoc选项实现了这个目的:

-linkoffline http://d.android.com/reference"file:/ C:/ Android/android-sdk-windows/docs/reference"

但是,基于我的Java代码行(而不是Javadoc注释),我得到以下错误:

C:\Users\Ellen\workspace\TestableToast\src\edu\mills\cs180\HelloAndroid.java:5: 
package android.view does not exist
import android.view.View;
                   ^ 
C:\Users\Ellen\workspace\TestableToast\src\edu\mills\cs180\HelloAndroid.java:6: 
package android.view.View does not exist 
import android.view.View.OnClickListener;
                        ^ 
C:\Users\Ellen\workspace\TestableToast\src\edu\mills\cs180\HelloAndroid.java:8: 
package android.widget does not exist
import android.widget.Toast;
                      ^ 
C:\Users\Ellen\workspace\TestableToast\src\edu\mills\cs180\HelloAndroid.java:10: 
cannot find symbol symbol: class Activity 
public class HelloAndroid extends Activity implements OnClickListener {
                                  ^

我该如何修复这些参考文献？
