Android日期和时间选择器实现代码

抽出来了一个方法来选择时间（这里自己规定的只能选择当前时间以后的日期），日期选择完毕就会自动弹出时间选择器让选择时间。

/** * 选择日期和时间 */ private void selectDataAndTime() { // 获取当前时间 final Calendar calendar = Calendar.getInstance(); /* * toast("当前时间是：" + calendar.get(Calendar.YEAR) + "," + * calendar.get(Calendar.MONTH) + "," + * calendar.get(Calendar.DAY_OF_MONTH)); */ // 日期选择对话框 dataPickerDialog = new DatePickerDialog(this, new OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int month, int day) { // 判断用户选择的日期是否合法 if (calendar.get(Calendar.YEAR) > year) { toast("时间有误，请从新选择"); return; } else if (calendar.get(Calendar.YEAR) == year) { if (calendar.get(Calendar.MONTH) > month) { toast("时间有误，请从新选择"); return; } else if (calendar.get(Calendar.MONTH) == month) { if (calendar.get(Calendar.DAY_OF_MONTH) > day) { toast("时间有误，请从新选择"); return; } else { strDate = year + "-" + (month + 1) + "-" + day; if (timePickerDialog != null) { timePickerDialog.show(); } } } else { strDate = year + "-" + (month + 1) + "-" + day; if (timePickerDialog != null) { timePickerDialog.show(); } } } else { strDate = year + "-" + (month + 1) + "-" + day; if (timePickerDialog != null) { timePickerDialog.show(); } } } }, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar .get(Calendar.DAY_OF_MONTH)); // 时间选择对话框 timePickerDialog = new TimePickerDialog(this, new OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hour, int minute) { strTime = strDate + " " + hour + ":" + minute; timeTt.setText(strTime); } }, calendar.get(Calendar.HOUR), calendar.get(Calendar.MINUTE), true); }
