Android SQLite表插入

我有这种形式，用户可以跟踪他们的位置，并给每个事件的昵称。我正在收集该昵称，并使用它来尝试在该数据库中以该名称形成一个新表。Android SQLite表插入

我要么得到一个

table does not exist

或

the data is added to the previous table without creating a new one.

需要采取哪些措施来得到这个新表添加到当前数据库？

这里是整个类：

public class MySQLiteHelper extends SQLiteOpenHelper { 

    public static final String TABLE_NAME = MainActivity.nickName; 
    public static final String COLUMN_ID = "_id"; 
    public static final String COLUMN_COMMENT = "comment"; 
    public static final String COLUMN_LAT = "lat"; 
    public static final String COLUMN_LONG = "long"; 
    public static final String COLUMN_RADI = "radi"; 




private static final String DATABASE_NAME = "logs.db"; 
private static final int DATABASE_VERSION = 1; 



    // Database creation sql statement 
    private static final String DATABASE_CREATE = "create table " 
     + TABLE_NAME + "(" + COLUMN_ID 
     + " integer primary key autoincrement, " + COLUMN_COMMENT 
     + " text not null," + COLUMN_LAT+ "," + COLUMN_LONG + "," + COLUMN_RADI + ");"; 


    MySQLiteHelper(Context context) { 
    super(context, context.getExternalFilesDir(null).getAbsolutePath() + "/" + DATABASE_NAME, null, DATABASE_VERSION); 
} 

    @Override 
    public void onCreate(SQLiteDatabase database) { 
     database.execSQL(DATABASE_CREATE); 


} 

@Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
    Log.w(MySQLiteHelper.class.getName(), 
     "Upgrading database from version " + oldVersion + " to " 
     + newVersion + ", which will destroy all old data"); 
db.execSQL("DROP TABLE IF EXISTS " + TABLE_COMMENTS); 
onCreate(db); 
} 

}

尝试以下查询：

String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "(" 
+ KEY_ID + " INTEGER PRIMARY KEY," + KEY_STARTDATE + " TEXT, " + KEY_STARTTIME + " TEXT, " 
+ KEY_TRIALID + " TEXT, " + KEY_TRIALNAME + " TEXT, " + KEY_ENDDATE + " TEXT, "+ KEY_ENDTIME + " TEXT, " + KEY_USERNAME + " TEXT"+")"; 


     values.put(KEY_STARTDATE, item.getStartdate()); 
values.put(KEY_STARTTIME, item.getStarttime()); 
values.put(KEY_TRIALID, item.getTrialid()); 
values.put(KEY_TRIALNAME, item.getTrialname()); 
values.put(KEY_ENDDATE, item.getEnddate()); 
values.put(KEY_ENDTIME, item.getEndtime()); 
values.put(KEY_USERNAME, item.getUsername());

您需要定义将数据插入到数据库的方法。

您还应该阅读这种类型的最佳做法。一个真正的好地方是：
