【移動(dòng)應(yīng)用開發(fā)技術(shù)】Android如何實(shí)現(xiàn)語音播放與錄音功能

這篇文章主要介紹Android如何實(shí)現(xiàn)語音播放與錄音功能，文中介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們一定要看完！具體內(nèi)容如下項(xiàng)目用到的技術(shù)點(diǎn)和亮點(diǎn)語音錄音（單個(gè)和列表）語音播放（單個(gè)和列表）語音錄音封裝語音播放器封裝語音列表順序播放語音列表單個(gè)播放復(fù)用問題處理因?yàn)榘惭b原生錄音不能錄mp3格式文件而mp3格式是安卓和ios公用的，所以我們需要的是能直接錄取mp3文件或者錄完的格式轉(zhuǎn)成mp3格式下面添加這個(gè)庫能直接錄mp3文件，我覺得是最方便的compile‘com.czt.mp3recorder:library:1.0.3'1.語音錄音封裝代碼簡(jiǎn)單自己看吧package

}

});

}

}

//核心方法

//點(diǎn)擊了某一個(gè)條目

這個(gè)條目isSelect=true

上一個(gè)條目isSelect需要改為false

防止滑動(dòng)過程中

幀動(dòng)畫復(fù)用問題
