Error "Unexpected namespace prefix" xmlns "found for tag linearlayout" workaround

When writing the layout code, I found an error in the XML script "unexpected namespace prefix" xmlns "found for tag LinearLayout", which is a namespace declaration as long as it appears once in XML, Multiple occurrences on the error, the old version does not require this, the new version has been improved.

Only the first declaration is retained, and the subsequent direct deletion is OK.
