如何解决Android Studio移动光标时制表符转空格的问题

• Verify core editor tab settings

  • Disable any option named "Convert tabs to spaces" (sometimes labeled "Insert spaces" instead of tabs). Double-check both global and per-language settings—some editors override global preferences for specific code languages.
  • Set your preferred "Tab size" (e.g., 4), but ensure the editor is configured to preserve tab characters rather than replace them with spaces automatically.

• Check for plugin/extension interference

  • Temporarily disable code formatting extensions (like Prettier, ESLint, or language-specific formatters). Many of these have hidden settings that auto-format whitespace on cursor movement or idle time, which could be converting tabs to spaces without your input.
  • Look for extensions focused on tab handling or whitespace management—these are often the source of unexpected overrides.

• Editor-specific adjustments

  • VS Code: Navigate to Settings > Text Editor > Formatting, uncheck "Format on Type" and "Format on Save". Under Text Editor > Files, ensure "Trim Trailing Whitespace" isn't altering your code unexpectedly.
  • Sublime Text: Open Preferences > Settings, set "translate_tabs_to_spaces": false and confirm "auto_indent" isn't configured to force space conversion.
  • Vim/Neovim: Add set noexpandtab to your .vimrc or init.vim to lock in tab preservation.

• Test in a clean editor environment

  • Launch your editor without plugins or custom configurations (e.g., VS Code with the --disable-extensions flag). If the problem disappears, you’ll know a plugin or modified setting is causing the tab-to-space conversion.

When you need precise alignment (like your example TabSpaceSpaceSpaceSpaceCode), you can manually mix tabs and spaces as needed—just ensure your editor isn’t overriding your intentional whitespace choices during navigation.
