As a newcomer to NativeScript technology, I often encounter challenges while developing applications. Whether it's troubleshooting why a textview is not displaying properly, identifying layout overlaps, or detecting other distortions in the UI, debugging has become an essential part of my process.
Thank you for taking the time to address these issues.
If you're looking to debug your UI in NativeScript, the process has evolved since previous answers mentioned it. Now, you can actually debug certain aspects of the UI.
1) Start by running the app on your emulator using a command like
tns debug android --bundle. This will give you a link similar to
chrome-devtools://devtools/bundled/inspector.html?experiments=true&ws=localhost:400002) Open this link in Chrome and navigate to the Elements tab to see the XML tree of elements. You can even make changes here by adding or altering attributes. For example, right-click on an element, choose "add attribute," and set color="blue" to change the font color for that element.
You'll be able to view the computed CSS on the right side, although modifying CSS directly from this interface is not as straightforward as in web development.
For more detailed instructions, check out the documentation at .
If a field appears misaligned, it may be due to using a negative margin or placing multiple items within an absolute or grid layout cell.
To troubleshoot, you can try the following commands:
tns debug ios --emulator
or
tns debug android --emulator
However, instead of debugging the JS code that constructs the screen, it is recommended to focus on understanding XML layouts and how they determine the positioning of elements. By gaining insight into how layouts work, you can identify any mistakes and correct them more effectively.
