Open the Eclipse -> Window -> Perferences, will open a Perferences settings interface.
The easiest way is to change: Windows -> Preferences -> Java -> Editor -> Content Asist, Auto activation triggers for Java in the text box after only one. "."
Will see only one "." Exist. Said: Only enter "." Tips only after a code, we need to modify the place is here, but the Eclipse default only allowed to input 4 custom characters.
But we can export the current settings, save as a file and then modified in the file, then import the settings, so that Eclipse can break through the restrictions.
First picture above "." Casual place to enter a few characters, such as "asdf", point at the bottom of the "OK" to save the settings.
Then open Eclipse, File -> Export, in the window, expand General -> Perferences -> Export
all and then click NEXT. Then click "Browse" to select any of a path, save the configuration file, then click "Finish".
Just use Notepad to open the saved configuration file (file extension: *. epf), press "ctrl +
F ", enter just set the" asdf ", to find just the string. The" asdf "revised to" abcdefghijklmnopqrstuvwxyz. ", Then save and exit Notepad.
Open Eclipse, File -> Import to open the window and then expand the General ->
Perferences, click NEXT, select just the modified configuration file, Finish. Now, open the Window ->
Perferences, and to expand Java -> Editor -> Content
Assist, will find more than 4 characters, that we enter any letter and "." Will have the code suggests.
Changes, the default is 200 milliseconds, you enter a character that appears after code hinting, if the input is the card, requiring the prompt delay to increase the number; if you think it is too slow, you can change into smaller numbers, but The smaller number of reform of the higher performance requirements, I set is 50 milliseconds. Now, Eclipse is not using it even more effortless?
