前言：添加了学习模块，所以做了一个每日一句的功能，主要是在天行数据申请了一个每日一句的api,之后用okgo，调取，并解析成对象。获取文字、图片、音频等。在线显示、播放。同时做了一个底部弹出日历选择。

效果图：

/**网络请求封装**/
implementation 'com.lzy.net:okgo:3.0.4'
/**日历选择器**/
implementation 'com.prolificinteractive:material-calendarview:1.4.3'

Json 格式：

    "code": 200,
    "msg": "success",
    "newslist": [
        {
            "id": 3725,
            "content": "Passion is a key ingredient to the study and practice of law and of life.",
