解决方案

要触发TimePicker ::>

  INT小时，分钟;
TimePickerDialog mTimePicker =新TimePickerDialog（mContext，
    新TimePickerDialog.OnTimeSetListener（）{
  @覆盖
  公共无效onTimeSet（TimePicker timePicker，诠释selectedHour，诠释selectedMinute）{
小时= selectedHour;
    分钟= selectedMinute;
 }
}，小时，分钟，FALSE）; //是24小时时间
mTimePicker.setTitle（选择时间）;
小时= c.get（Calendar.HOUR）;
分钟= c.get（Calendar.MINUTE）;
mTimePicker.updateTime（小时，分钟）;
mTimePicker.show（）;
 

I keep on getting this issue whenever I click on Timepicker. This issue is not occurring on any other devices, Following is the error log:

解决方案

Add this where you want to Trigger TimePicker::>

int hour,minute;
TimePickerDialog mTimePicker = new TimePickerDialog(mContext, 
    new TimePickerDialog.OnTimeSetListener() {
  @Override
  public void onTimeSet(TimePicker timePicker,int selectedHour, int selectedMinute) {
hour = selectedHour;
    minute = selectedMinute;
 }


}, hour, minute, false);// Yes 24 hour time
mTimePicker.setTitle("Select Time");
hour = c.get(Calendar.HOUR);
minute = c.get(Calendar.MINUTE);
mTimePicker.updateTime(hour, minute);
mTimePicker.show();
