github 地址：GitHub - Bigkoo/Android-PickerView: This is a picker view for android , support linkage effect, timepicker and optionspicker.（时间选择器、省市区三级联动）

1.引用库

implementation 'com.contrarywind:Android-PickerView:4.1.9'

2. 实现逻辑

public class TimeSelectDialog {
    private Activity activity;
    private ViewGroup contentView;
    private View view;
    private WheelView wvHour;
    private WheelView wvMinute;
    private List hourList;
    private List minuteList;
    public TimeSelectDialog(Activity activity) {
        this.activity = activity;
        contentView = activity.findViewById(android.R.id.content);
        view = LayoutInflater.from(activity).inflate(R.layout.dialog_time_select, null);
         wvHour = view.findViewById(R.id.wv_hour);
         wvMinute = view.findViewById(R.id.wv_minute);
        TextView tvCancel = view.findViewById(R.id.tv_cancel);
        TextView tvSure = view.findViewById(R.id.tv_sure);
        tvCancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        tvSure.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        //第一种方式
        initHourWheelView();
        initMinuteWheelView();
        
        //第二种方式
        /*initTimePickerBuilder();*/
    }
    /**
     * 初始化时间选择器控件
     */
    private void initTimePickerBuilder() {
        Calendar startDate = Calendar.getInstance();
        Calendar endDate = Calendar.getInstance();
        //正确设置方式 原因：注意事项有说明
        startDate.set(startDate.get(Calendar.YEAR)-50,0,1);//-50往前推50年
        endDate.set(endDate.get(Calendar.YEAR)+50,11,31);//+50往后推50年
        TimePickerView tpv = new TimePickerBuilder(activity, new OnTimeSelectListener() {
            @Override
            public void onTimeSelect(Date date, View v) {
            }
        }).setDecorView(view.findViewById(R.id.ll_tpv_container))//设置父控件
                .isDialog(false)//非弹框模式
                .setItemVisibleCount(5)//显示5行
                .setDate(Calendar.getInstance())//当前时间
                .setRangDate(startDate,endDate)//起始终止年月日设定
                .build();
        //隐藏选择器上面的标题栏
        int topbarId = activity.getResources().getIdentifier("rv_topbar", "id", activity.getPackageName());
        tpv.findViewById(topbarId).setVisibility(View.GONE);
        tpv.show();//显示
    }
    /**
     * 小时
     */
    private void initHourWheelView() {
        hourList = new ArrayList();
        for (int i = 0; i  
 2.布局实现 dialog_time_select.xml
 

    
        
        
        
            
            
        
        
            
            
        
    
 
3.dialog动画
 
dialog_in_anim.xml
 

    
 
dialog_out_anim.xml
 

    
 
4.时间选择器弹框：
 
new TimeSelectDialog(activity).show(null);
