When editing XML files in the editor for Eclipse, line numbers are not displayed.
I create a layout with many views, one of these lacks android:layout_width attribute. This causes a runtime error when the binary XML layout resource is inflated. The error log tells me to check like 361 in my XML file.
Thanks to the line number being displayed I can find the offending line and make the change without having to open the file in another editor.
try right clicking the grey bar and selecting show line numbers it works for me so hopefully it will for u too
or change it in the settings
File > Settings > Editor > Appearance then click the "Show line numbers" box.
