WheelPicker
项目介绍
- 项目名称:WheelPicker
- 所属系列:openharmony的第三方组件适配移植
- 功能:自定义 View 实现滑动流畅、功能齐全、用法简单、高度自定义的 WheelView,并在 WheelView 基础之上封装了常用的日期选择器(包括年、月、日 WheelView)、选项选择器
- 项目移植状态:已完成,3D弯曲效果暂不支持
- 调用差异:无
- 开发版本:sdk6,DevEco Studio2.2 Beta1
- 基线版本:Release w1.0.7_p1.0.9
效果演示
安装教程
1.在项目根目录下的build.gradle文件中,
allprojects {
repositories {
maven {
url 'https://s01.oss.sonatype.org/content/repositories/releases/'
}
}
}
2.在entry模块的build.gradle文件中,
dependencies {
implementation('com.gitee.chinasoft_ohos:WheelPicker-wheelview:1.0.0')
implementation('com.gitee.chinasoft_ohos:WheelPicker-Picker:1.0.0')
......
}
在sdk6,DevEco Studio2.2 Beta1下项目可直接运行 如无法运行,删除项目.gradle,.idea,build,gradle,build.gradle文件, 并依据自己的版本创建新项目,将新项目的对应文件复制到根目录下
使用说明
WheelView
- 布局文件定义,提供控件:WheelView
<com.zyyoona7.wheel.WheelView
ohos:id="@+id/wheelview"
ohos:layout_width="wrap_content"
ohos:layout_height="wrap_content"/>
2、在 AbilitySlice 中,这样配置
//泛型为数据类型
final WheelView<Integer> wheelView = findViewById(R.id.wheelview);
//初始化数据
List<Integer> list = new ArrayList<>(1);
for (int i = 0; i < 20; i++) {
list.add(i);
}
//设置数据
wheelView.setData(list);
//尽请使用各种方法
wheelView.setTextSize(24f,true);
//more...

.进阶用法(Advanced Usage)
问:我已经有了创建好的实体怎么办?
答:好办~
我已城市列表为例(其他实体同理)
我的城市列表实体是这样的:
public class CityEntity implements IWheelEntity, Serializable { //国家 public static final String LEVEL_COUNTRY = "country"; //省 public static final String LEVEL_PROVINCE = "province"; //市 public static final String LEVEL_CITY = "city"; //区 public static final String LEVEL_DISTRICT = "district"; private String citycode; private String adcode; private String name; private String center; private String level; private List<CityEntity> districts; public String getCitycode() { return citycode; } public void setCitycode(String citycode) { this.citycode = citycode; } public String getAdcode() { return adcode; } public void setAdcode(String adcode) { this.adcode = adcode; } public String getName() { return name == null ? "" : name; } public void setName(String name) { this.name = name; } public String getCenter() { return center; } public void setCenter(String center) { this.center = center; } public String getLevel() { return level; } public void setLevel(String level) { this.level = level; } public List<CityEntity> getDistricts() { return districts == null ? new ArrayList<CityEntity>(1) : districts; } public void setDistricts(List<CityEntity> districts) { this.districts = districts; } @Override public String toString() { return "CityEntity{" + "citycode='" + citycode + '\'' + ", adcode='" + adcode + '\'' + ", name='" + name + '\'' + ", center='" + center + '\'' + ", level='" + level + '\'' + ", districts=" + districts + '}'; } /** * 重点:重写此方法,返回 WheelView 显示的文字 * @return */ @Override public String getWheelText() { return name == null ? "" : name; } }
注意,我的 CityEntity 中多实现了一个 IWheelEntity 接口,这个接口是在 WheelView 库中定义好的,实现之后在 getWheelText() 方法返回你想在 WheelView 中展示的字段就大功告成了。
MainActivity WheelView 相关代码:
WheelView<CityEntity> cityWv=findViewById(R.id.wv_city);
//解析城市列表
List<CityEntity> cityData= ParseHelper.parseTwoLevelCityList(this);
cityWv.setData(cityData);
如果条件都不满足的话会默认执行 toString() 方法,所以理论上也可以在实体的 toString() 方法返回你想展示的字段,但是不推荐,毕竟 toString() 方法以我个人的习惯都是输出 CityEntity 那种的信息~你也可能输出别的信息。
PickerView Usage
DatePickerView Usage
在布局文件中:
<com.zyyoona7.picker.DatePickerViewEx
ohos:height="match_content"
ohos:width="match_parent"
/>
代码中:
//展示年月日
setPickerDisplay(mYear, isDisplayYear);
setPickerDisplay(mMonth, isDisplayMonth);
setPickerDisplay(mDay, isDisplayDay);
// 设置选中颜色
setPickTextColor(mYear, mSelectedColorYear, mNormalColorYear);
setPickTextColor(mMonth, mSelectedColorMonth, mNormalColorMonth);
setPickTextColor(mDay, mSelectedColorDay, mNormalColorDay);
OptionsPickerView
在布局文件中:
<com.zyyoona7.picker.CityPicker
ohos:id="$+id:picker_city"
ohos:height="160vp"
ohos:width="match_parent"
ohos:bottom_padding="10vp"
ohos:start_margin="10vp"
ohos:top_margin="5vp"
ohos:background_element="#FFD9D5D5"
app:select_background="false"
app:isshow_shadow="true"
app:issound="true"
>
</com.zyyoona7.picker.CityPicker>
代码中:
pickerCity = (CityPicker) findComponentById(ResourceTable.Id_picker_city);
pickerCity.setOnePickerValue(sign);
pickerCity.setTwoPickerValue(sign2);
pickerCity.setThreePickerValue(sign3);
