WheelPicker自定义时间选择器控件

本文实例为大家分享了WheelPicker自定义时间选择器控件的具体代码，供大家参考，具体内容如下

先上图：

使用android自带的DatePicker控件虽然也能实现功能，但样式不能改变。想要实现一些自定义的样式，就要用到WheelPicker了。

要使用WheelPicker，需要先导入WheelPicker的引用：

1. 在project的build.gradle添加如下代码

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

2. 在Module的build.gradle添加依赖

compile 'com.github.open-android:WheelPicker:v1.0.0'

3.复制如下代码到xml中：

<com.itheima.wheelpicker.WheelPicker
    android:id="@+id/wheel_date_picker_month"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp"
    app:wheel_atmospheric="true"
    app:wheel_curved="true"
    app:wheel_cyclic="true"
    app:wheel_selected_item_position="5"
    app:wheel_item_text_color="@color/text_white"
    app:wheel_selected_item_text_color="@color/orange"/>

wheel_atmospheric : 条目颜色是否执行衔接处理效果更好
wheel_curved ：是否是弧形状态显示
wheel_cyclic : 是否可循环
wheel_selected_item_position ：默认选中第几个条目

然后使用即可。
