1.导入依赖
//时间选择器

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

2初始化

private TimePickerView pvTime; //时间选择器对象
 private TextView textBirthdayEd;


//初始化时间选择器
    private void initTimePicker() {
        Calendar selectedDate = Calendar.getInstance();
        Calendar startDate = Calendar.getInstance();
        startDate.set(1900, 1, 1);//起始时间
        Calendar endDate = Calendar.getInstance();
        endDate.set(2099, 12, 31);//结束时间
         pvTime= new TimePickerBuilder(this, new OnTimeSelectListener() {
                @Override
                public void onTimeSelect(Date date, View v) {
                    //选中事件回调
                    //mTvMyBirthday 这个组件就是个TextView用来显示日期 如2020-09-08
                    textBirthdayEd.setText(getTimes(date));
                }
            })
                //年月日时分秒 的显示与否，不设置则默认全部显示
                .setType(new boolean[]{true, true, true, false, false, false})
                .setLabel("年", "月", "日", "时", "", "")
                .isCenterLabel(true)
                .setDividerColor(Color.DKGRAY)
                .setTitleSize(21)
                .setDate(selectedDate)
                .setRangDate(startDate, endDate)
                .setDecorView(null)
                .build();
    }

    //格式化时间
    private String getTimes(Date date) {
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
        return format.format(date);
    }


  textBirthdayEd = (TextView) findViewById(R.id.text_birthday_ed);
        //选择生日
        textBirthdayEd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                initTimePicker(); //初始化时间选择器
                pvTime.show();//显示时间选择器
            }
        });
