WheelPicker自定義時間選擇器控件的方法

小編給大家分享一下WheelPicker自定義時間選擇器控件的方法，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

本文實例為大家分享了WheelPicker自定義時間選擇器控件的具體代碼，供大家參考，具體內容如下

先上圖：

使用android自帶的DatePicker控件雖然也能實現功能，但樣式不能改變。想要實現一些 自定義的樣式，就要用到WheelPicker了。

要使用WheelPicker，需要先導入WheelPicker的引用：

1. 在project的build.gradle添加如下代碼

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

2. 在Module的build.gradle添加依賴

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

3.復制如下代碼到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 :  條目顏色是否執行銜接處理 效果更好

• wheel_curved ： 是否是弧形狀態顯示

• wheel_cyclic : 是否可循環

• wheel_selected_item_position ： 默認選中第幾個條目

然后使用即可。
