It’s all explained in detail in the following tutorial: ContentValues args = new ContentValues() ĭb.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null) String args = new String ĭb.update("YOUR_TABLE", newValues, "name=? OR name=?", args) NewValues.put("YOUR_COLUMN", "newValue") ĭb.update("YOUR_TABLE", newValues, "id=6", null) Or ContentValues newValues = new ContentValues() You can try: db.execSQL("UPDATE DB_TABLE SET YOUR_COLUMN='newValue' WHERE id=6 ") MyDB.update("titles", args, strFilter, null) String strFilter = "_id=" + Id ĬontentValues args = new ContentValues() In the lesson, there is one update function that requires all of the parameters, but I only want to update one column. Now I just want to change the value of one column the others will remain unchanged. In Android, one may create and use databases.Įverything is in order. I followed the instructions in this guide.
