Android Studio 3.0查找替换功能异常求助（Ubuntu 16.04环境）

Hey there! I ran into the exact same frustrating behavior when upgrading from Android Studio 2.3 to 3.0 on Ubuntu, so I’ve got you covered with the fixes for both find and replace functions:

Fixing Ctrl-F (Find) Partial Matching #

The root cause here is that Android Studio 3.0 enables the Whole Word matching mode by default, which forces you to type full words to get results. Here’s how to fix it:

• Open the find dialog with Ctrl+F.
• Look at the top-right corner of the find box: there’s an icon that looks like ab enclosed in a square (this is the Whole Word toggle). Click it to deselect it—your search box will stop turning red when you type partial strings, and you’ll get matches like "us" finding "used".
• Pro tip: You can also use the keyboard shortcut Alt+W to quickly toggle this mode without reaching for the mouse.

Fixing Ctrl-R (Replace) Partial Matching #

For replace operations (especially when editing XML layout IDs), the issue ties back to the same matching mode settings. Follow these steps:

• Open the replace dialog with Ctrl+R.
• In the top-right corner of the replace box, locate the same Whole Word toggle icon (ab in a square) and deselect it. This lets the tool find substrings instead of only full words.
• If you’re working with XML IDs, make sure the Regex mode (the .* icon next to the Whole Word toggle) is not enabled unless you specifically need regex matching—this can mess with standard substring searches.
• Quick workflow for batch editing XML IDs: Select the partial ID substring you want to replace, hit Ctrl+R (the selected text will auto-fill the "Find" field), adjust the matching modes as needed, enter your replacement text, and use "Replace All" to update all instances at once.

Setting Default Matching Mode (Optional) #

If you don’t want to toggle this setting every time, you can change the default behavior in Android Studio’s settings:

• Open the Settings dialog with Ctrl+Alt+S (or go to File > Settings).
• Navigate to Editor > Find.
• Under the "Find" section, uncheck the "Whole words only" option. This will make partial matching the default for all future find/replace operations.
