很多的應(yīng)用為了應(yīng)用的推廣和傳播都會(huì)使用“分享”的功能，點(diǎn)擊分享按鈕，就能將想要分享的內(nèi)容或者圖片分享至QQ空間、微博、微信朋友圈等實(shí)現(xiàn)了分享功能的應(yīng)用。這篇文章主要是為了學(xué)習(xí)與探索調(diào)用系統(tǒng)實(shí)現(xiàn)分享功能或者直接調(diào)起實(shí)現(xiàn)了分享功能的應(yīng)用的activity來進(jìn)行分享。
目前實(shí)現(xiàn)一鍵分享功能的方式有兩種：
1.需要集成第三方官方SDK包，在獲得官方授權(quán)后調(diào)用其API來完成一鍵分享功能，例如使用友盟分享等
優(yōu)點(diǎn)：無縫集成，功能多
缺點(diǎn)：需要集成官方的SDK包并通過申請官方的授權(quán)才可進(jìn)行開發(fā)
2.不需要使用任何第三方SDK包，可以直接調(diào)起實(shí)現(xiàn)了分享功能的應(yīng)用的activity來進(jìn)行分享
優(yōu)點(diǎn)：不需要使用任何第三方SDK包和申請官方授權(quán)
缺點(diǎn)：需要手機(jī)安裝你需要分享的應(yīng)用（這一點(diǎn)非常重要，一開始測試的時(shí)候一直不成功，提示“沒有應(yīng)用可執(zhí)行此操作”，后來找了很久才發(fā)現(xiàn)是我手機(jī)沒有安裝相對應(yīng)的應(yīng)用，這也是不好方便的地方）
按照慣例先來看一下最終效果圖：

由于分享功能是使用隱式調(diào)用Activtiy實(shí)現(xiàn)的，則需在響應(yīng)的Activity中聲明intent-filter，在對應(yīng)的activity的xml里加上
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
