大概的效果就和原來圖差不多。
思路解析:車牌號(hào)碼由31位漢字,26位字母,10位數(shù)字組成的,開頭第一位由省份簡稱的漢字,第二位字母根據(jù)省份下的城市或地區(qū)區(qū)分,最后的五位或者六位,是有字母和數(shù)字組成的,共有七位的車牌號(hào)碼和八位的車牌號(hào)碼,(注:其中的八位數(shù)的車牌號(hào)碼為能源車的車牌號(hào)碼。)
大概的邏輯思維,不包含代碼獲取值什么的或者驗(yàn)證其他的說明,詳細(xì)看代碼片段。
第一,原型的設(shè)計(jì)思路:先設(shè)計(jì)好模擬鍵盤的大概架構(gòu),樣式。這里的分為三個(gè)不同的模擬鍵盤結(jié)構(gòu)合在一起,分部為漢字,字母,數(shù)字,其樣式統(tǒng)一;
第二:數(shù)據(jù)的交互思路:對(duì)需要的數(shù)據(jù)綁定或者修改填充等,如何獲取,通過什么方式獲取,再怎么反饋出來,需要搭建好數(shù)據(jù)的來回交互傳遞的大概模型;
第三,交互的體驗(yàn)思路:觸發(fā)或者在輸入框點(diǎn)擊輸入的時(shí)候,啟動(dòng)模擬鍵盤,先用漢字選擇,其次是字母,最后由字母和數(shù)字混合,對(duì)三個(gè)架構(gòu)先進(jìn)行需求排序的理清;
第四,功能的操作思路:模擬鍵盤的功能性按鈕,比如數(shù)字與字母之間的的切換,刪除最后一位數(shù)據(jù),清空全部數(shù)據(jù)和狀態(tài),關(guān)閉的結(jié)束等操作等體驗(yàn)。
第五:輸入判斷的思路:判斷車牌號(hào)碼輸入的位數(shù),第一位和第二位分部是什么,字母與數(shù)字的切換的判斷。刪除到第幾位需要在什么樣的狀態(tài)輸入下等。
大概就這這些樣子了,能寫怎么多字,感覺都超綱了,如果有錯(cuò)的地方,還望留言指正。
最后是源碼:
