Ctrl + Space not working for content assist on eclipse
提问by Ivaylo Toskov
My problem is that the content assist window won't pop up after clicking Ctrl + Space. I checked my shortcuts and the content assist is bound to Ctrl + Space. Sometimes the window automatically pops up making suggestion after typing dot e.g., but this won't happen when using the keys combination.
我的问题是单击 后不会弹出内容辅助窗口Ctrl + Space。我检查了我的快捷方式，内容辅助绑定到Ctrl + Space. 有时输入 dot eg 后会自动弹出建议窗口，但使用组合键时不会发生这种情况。

I managed to fix it finally. The problem was that the ibus was overriding the shortcut so I deleted this shortcut configuration.
我终于设法修复了它。问题是 ibus 覆盖了快捷方式，所以我删除了这个快捷方式配置。
Type ibusin the dash:
键入的ibus在仪表板：
Then select Keyboard Input Methods. From there click on the first three dots next to the Enable or disabletextfield. This windows should appear:
然后选择键盘输入法。从那里单击启用或禁用文本字段旁边的前三个点。这个窗口应该出现：
If there is something bound to Ctrl + Spacesimply delete it.
如果有绑定到Ctrl + Space 的东西，只需将其删除即可。

就我而言；窗口>首选项>Java>编辑器>内容辅助>高级
Make sure Select the proposal>Template Proposals,SWT Template Proposals,Java Proposals ,Content assist cycling>Template Proposals,SWT Template Proposals,Java Proposals is ticked.
确保选中提案>模板提案，SWT模板提案，Java提案，内容辅助循环>模板提案，SWT模板提案，Java提案。

Go to Windows > Preferences > Java > Editor > Content Assist > Advanced > select all Java only. If you select all, then multiple occurrence of same instance would be shown in Suggestion list. which might be annoying some times.
转到 Windows > Preferences > Java > Editor > Content Assist > Advanced > 仅选择所有 Java。如果选择全部，则建议列表中将显示多次出现的相同实例。有时可能会很烦人。

Click on Apply and close it.

转到 Windows --> 首选项 --> Java --> 编辑器 --> 内容辅助 --> 高级 --> 选择所有 Java 和 Java 类型建议。
单击应用并关闭它。

It happened to me also, What I have done is change the workspacefolder to Another folder and problem solved!
这也发生在我身上，我所做的是将工作区文件夹更改为另一个文件夹，问题解决了！

This issue happened to me and none of the stack solutions seemed to resolve it. I finally figured that some other windows task was stealing my hotkey press. If nothing else works, I recommend that you downloaded a free software 'Windows Hotkey Explorer' that reported the registered hotkeys.
这个问题发生在我身上，似乎没有一个堆栈解决方案可以解决它。我终于发现其他一些 Windows 任务正在窃取我的热键按下。如果没有其他效果，我建议您下载一个免费软件“ Windows 热键资源管理器”，该软件会报告已注册的热键。
In my particular situation, I found ctrl+space was seized by 'blackboard collaborate' (a unpalatable java application for webcasts used by some of my courses).
在我的特殊情况下，我发现 ctrl+space 被“黑板协作”（我的一些课程使用的网络广播的令人讨厌的 Java 应用程序）占用了。
I closed Eclipse killed all java processes (which included blackboard). Restarted eclipse and my autocomplete was back!
我关闭 Eclipse 杀死了所有 java 进程（包括黑板）。重新启动日食，我的自动完成又回来了！
(Note: Hotkey Explorer was incredibly buggy and crashed every time I used it. I was able to get the information I needed before it crashed though so it was useful. Another (shareware) application that I didn't use but noticed online is: Hotkey Commander.
（注意：Hotkey Explorer 的错误令人难以置信，每次我使用它都会崩溃。我能够在它崩溃之前获得我需要的信息，所以它很有用。另一个我没有使用但在网上注意到的（共享软件）应用程序是：热键指挥官。

我尝试了很多选择，但没有任何选择。
Finally this was work out
终于解决了
Go to Preferences > Java > Editor > Content Assist > The "Auto activation triggers for Java:" field. Paste "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz." (note the dot after z) .This is the best solution and no need to even press ctrl+space.
转至首选项 > Java > 编辑器 > 内容辅助 >“Java 的自动激活触发器：”字段。粘贴“ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz”。（注意 z 后面的点）。这是最好的解决方案，甚至不需要按 ctrl+space。

Though I have eclipse proposal settings configured properly it was not working for me. In my case Ctrl+space key combination was hiHymaned by another background running process (I was running AllwaysOnTop utility for windows). it worked after exit that process. :)
尽管我正确配置了 eclipse 建议设置，但它对我不起作用。在我的情况下，Ctrl+空格键组合被另一个后台运行进程劫持（我正在运行 Windows 的 AllwaysOnTop 实用程序）。它在退出该过程后工作。:)
