鸿蒙Next进度条组件Progress的使用

进度条组件，用于显示内容加载或操作处理等进度 官方提供了5种类型的进度条，看一下演示效果： 注意：只有环形进度条Ring支持设置渐变色 1.设置ProgressOptions | 名称 | 说明 |
|------------|-------------| | value|指定当前进度值。设置小于0的数值时置为0，设置大于total的数值时置为total | total | 指定进度总长。设置小于等于0的数值时置为100| | type| 指定进度条类型 |

2.style(value: ProgressStyleOptions | CapsuleStyleOptions | RingStyleOptions | LinearStyleOptions | ScaleRingStyleOptions | EclipseStyleOptions) 3.详细看代码中注释
