Android騰訊微博客戶端開發(fā)四:微博發(fā)送篇(QQ表情,@搜索)

A罩杯 · 發(fā)表于 2013-8-28 16:28

有一個(gè)問題，誰做過android的自定義表情?。棵菜七€沒有發(fā)現(xiàn)有客戶端有，都是圖片，如果能像在電腦上那樣自定義表情的功能多好，那位大哥知道，麻煩告知一聲，呵呵。寫完，睡覺。

我們仔細(xì)來觀察下騰訊微博的qq表情發(fā)送規(guī)律，由/開始,1到3個(gè)中文或者英文字符.

寫個(gè)工具類來測(cè)試已測(cè)試正則表達(dá)式來匹配表情。



在上方輸入框中可以輸入查詢格式為 @你選擇的列表值

這個(gè)是話題輸入界面，格式為#話題#

表情選擇頁面，這個(gè)其實(shí)是一個(gè)每行5列的GridView


此界面可看到你寫的微博的內(nèi)容，點(diǎn)擊發(fā)送，發(fā)送成功

哈哈，看到了吧，我的微博首頁已經(jīng)顯示了我剛才發(fā)送的帶有話題@person和表情的微博了。

接下來，上代碼。
