WheelPicker自定義時間選擇器控件
本文實例為大傢分享瞭WheelPicker自定義時間選擇器控件的具體代碼,供大傢參考,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瞭。
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
然後使用即可。
