When editing XML files in the editor for Eclipse, line numbers are not displayed.
Use case:
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.
If you view source in chrome, it will show line numbers (assuming your source XML file is separated into different lines). "View page source" on Mozilla Firefox also displays the XML document, with numbered lins.
Go to plugins -> Android support and disable this. Restart Android studio and enable the plugin again. Worked for me.
Android provides a straightforward XML vocabulary that corresponds to the View classes and subclasses, such as those for widgets and layouts. You can also use Android Studio's Layout Editor to build your XML layout using a drag-and-drop interface. Instantiate layout elements at runtime.
Location in Android Studio: You will find out this file inside the res folder and inside it there is another folder named layout where you will get all the layout files for their respective activities or fragments.
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.
If you're using Android Studio, you can show the line numbers by going to File > Settings > Editor > General > Appearance
, then check the "Show line numbers" box.
UPDATE: Android Studio v1.5+
1) Click inside the editor, Command + Shift + A, and type "show line numbers"
2) Select the second option in Preferences and it will take you to the screen that used to exist in General > Appearance
3) Check the "Show Line Numbers" box
