Eclipse內容輔助錯誤

Question

最近，我一直在使用Eclipse中的內容輔助方面遇到越來越多的問題。在我的一些項目中，我沒有收到內容協助的建議，在其他項目中，我收到了部分或全部預期建議。通常不存在「錯誤」在Eclipse中，但這裏是當我得到一個錯誤中的一個例子：

"Content Assist" did not complete normally. Please see the log for more information. Pb(324) The type android.support.v4.app.LoaderManager$LoaderCallbacks cannot be resolved. It is indirectly referenced from required .class files

我已經從類似的問題試過了各種建議（包括但不限於以下兩個）沒有運氣。我甚至已經刪除並重新安裝eclipse，並重新創建沒有任何Eclipse元數據或設置的項目。

• Eclipse Content Assist not working with Android
• Eclipse/Java code completion not working

任何幫助是極大的讚賞。

的Eclipse SDK 版本：3.7.2 版本ID：M20120208-0800

的Android開發工具包 版本：18.0.0.v201203301601-306762

Answer 1

我最終將ActionBarSherlock庫升級到最新的4.1（http://actionbarsherlock.com/），它修復了我的eclipse問題。

Answer 2

試試這個

窗口>>首選項>> Java >> Editor >> Content Assist >>恢復默認值

窗口>>首>> >>的Java編輯器>>內容輔助>>高級>>恢復默認值

Answer 3

我有一個類似的問題與使用V4兼容庫項目，當它被更新。嘗試移除庫上的項目依賴項，重新啓動Eclipse，然後重新添加依賴項（我想認爲這是我所做的解決此問題的方法，但如果這樣做不起作用，我會嘗試去考慮我可能做了什麼）

Answer 4

我也有這個問題，Pb（324）消息。事實證明，閱讀理解的信息足以解決問題。然而，我第一次做的是要疊加。沒有好:)

在我的groovy項目中，依賴庫不能通過自動完成自動顯示。不知道爲什麼，我是這個新手。所以我手動添加它們。但我沒有手動添加間接依賴項。錯誤消息指定導致問題的類。 我添加了對包含有問題的類和賓果遊戲的jar的引用 - 沒有更多的代碼幫助錯誤。

具體：項目，屬性，Java構建路徑，庫，添加外部JAR。然後我指向目錄，gradle下載了lib。
