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

  1. 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"/>
  1. 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...

3.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);
