android SQLite 优化（二）使用ContentValues 优化 insert

最快，也最灵活的实现，

你可以使用insert or fail 或 insert or ignore 来替换简单的insert

代码：

        	String[] sCheeseNames = {"a","b","a","b","a","b","a","b"};
        	String[] sCheeseOrigins = {"aa","bb","aa","bb","aa","bb","aa","bb"};
        	SQLiteDatabase db = SQLiteDatabase.create(null);
        	ContentValues values = new ContentValues();
        	int i = 0;
        	for (String name:sCheeseNames){
        		String origin = sCheeseOrigins[i++];
        		values.clear();
        		values.put("name", name);
        		values.put("origin", origin);
        		db.insert("cheese", null, values);
        	}

也可以使用DatabaseUtils.InsertHelper 执行多行插入，这样只需要编译一次insert 语句，但灵活性没有上面的方法好
