支持滑动停止后，指示器调整到刻度线之下。 7 | 3. 可以设置初始值、最大值、最小值。 8 | 4. 支持以下自定义属性： 9 | - gap_width 最小刻度所显示出来的宽度 10 | - init_value 初始值 11 | - number_margin_top 数字上边距 12 | - number_margin_bottom 数字下边距 13 | - tape_height 刻度高度 14 | - tape_color 刻度颜色 15 | - tape_width 刻度宽度 16 | - indicator_color 指示器颜色 17 | - indicator_width 指示器宽度 18 | - indicator_height 指示器高度 19 | - number_color 数字颜色 20 | - number_size 数字字体大小 21 | - max_value 最大值 22 | - min_value 最小值 23 | ### 觉得还不错的给个start，哈哈。 24 | -------------------------------------------------------------------------------- /.idea/gradle.xml:
