Yes, it is possible to change the name of a column in a SQLite database using Android Studio without having to create a new database. This can be done using an ALTER TABLE statement to rename the column. The following is an example of how to rename a column named "oldcolumnname" to "newcolumnname" in a table named "table_name":

SQLiteDatabase db = dbHelper.getWritableDatabase();
String alterQuery = "ALTER TABLE table_name RENAME COLUMN old_column_name TO new_column_name";
db.execSQL(alterQuery);
db.close();

Note that the above code assumes that you have a helper class named "dbHelper" that extends SQLiteOpenHelper and provides access to the database.
