Android 滚动时间选择的示例代码

效果图 复制代码直接用！！！！

1.导入依赖

implementation 'com.bigkoo:pickerview:2.1.0'

2.三个bean类
PickerViewData

public class PickerViewData implements IPickerViewData {
  private String content;

  public PickerViewData(String content) {
    this.content = content;
  }

  public void setContent(String content) {
    this.content = content;
  }

  @Override
  public String getPickerViewText() {
    return content;
  }
}

ProvinceBean

public class ProvinceBean implements IPickerViewData {
  private long id;
  private String name;
  private String description;
  private String others;

  public ProvinceBean(long id,String name,String description,String others){
    this.id = id;
    this.name = name;
    this.description = description;
    this.others = others;
  }

  public long getId() {
    return id;
  }

  public void setId(long id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public String getDescription() {
    return description;
  }

  public void setDescription(String description) {
    this.description = description;
  }

  public String getOthers() {
    return others;
  }

  public void setOthers(String others) {
    this.others = others;
  }

  //这个用来显示在PickerView上面的字符串,PickerView会通过IPickerViewData获取getPickerViewText方法显示出来。
  @Override
  public String getPickerViewText() {
    return name;
  }
}

TimeBean

public class TimeBean implements IPickerViewData {
  private String time;

  public TimeBean(String time) {
    this.time = time;
  }

  public String getTime() {
    return time;
  }

  public void setTime(String time) {
    this.time = time;
  }

  @Override
  public String getPickerViewText() {
    return time;
  }
}

3,布局文件activity_main

4.MainActivity

public class MainActivity extends Activity {


  private ArrayList options1Items = new ArrayList<>();
  private ArrayList> options2Items = new ArrayList<>();
  private ArrayList>> options3Items = new ArrayList<>();
  private TextView tvTime, tvOptions;
  TimePickerView pvTime;

    tvTime=(TextView) findViewById(R.id.tvTime);
    tvOptions=(TextView) findViewById(R.id.tvOptions);
    //时间选择器
    pvTime = new TimePickerView(this, TimePickerView.Type.MONTH_DAY_HOUR_MIN);
    //控制时间范围
//    Calendar calendar = Calendar.getInstance();
//    pvTime.setRange(calendar.get(Calendar.YEAR) - 20, calendar.get(Calendar.YEAR));//要在setTime 之前才有效果哦
    pvTime.setTime(new Date());
    pvTime.setCyclic(false);
    pvTime.setCancelable(true);
    //时间选择后回调
    pvTime.setonTimeSelectListener(new TimePickerView.onTimeSelectListener() {

      @Override

      }
    });
    //弹出时间选择器
