第二阶段团队冲刺3

一、认领任务

经过团队讨论，我认领到的工作是：在每日运动界面运动类型添加spinner下拉选择；

二、任务完成时间估算

界面跳转

效果:

主要的实现代码：

exercise.java

            }
            return null;
        }


    }
}

xml添加了

<Spinner
            android:id="@+id/spinnner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:entries="@array/ctype"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintVertical_bias="0.427" />

arrays

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="ctype">
        <item>打卡项目</item>
        <item>练瑜伽</item>
        <item>打篮球</item>
        <item>踢足球</item>
        <item>身体素质训练</item>
        <item>打羽毛球</item>
        <item>打乒乓球</item>
        <item>游泳</item>
        <item>练拳击</item>
        <item>有氧跑</item>
    </string-array>
</resources>

遇到的问题：

选择后获取不到值
