android中Timepicker的Stackoverflow错误？

Question

我正在使用时间选择器通过对话框片段。在那个时间选择器设置了最小和最大时间。当我点击减号（现在是最小值的时间，以分钟为单位）按钮分钟时间选择器时，我得到了堆栈溢出错误在API 10中，但在API 15中，它的工作正常。无法获得此问题的解决方案。任何人都知道帮助我解决此问题。

时间选择器对话框片段类

package data.picker;

import java.text.DateFormat;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.app.TimePickerDialog.OnTimeSetListener;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.widget.TimePicker;

public class Time_picker extends DialogFragment{

OnTimeSetListener ontimeSet;

int minHour;
int minMinute;

private int maxHour = 24;
private int maxMinute =00;
DateFormat dateFormat;
public Time_picker() {

}

public void setCallBack(OnTimeSetListener ontime) {

    ontimeSet = ontime;

}

private int hours, minutes;
@Override
public void setArguments(Bundle args) {
    super.setArguments(args);
    hours = args.getInt("hours");
    minutes = args.getInt("minute");

    minHour = hours;
    minMinute = minutes;
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    TimePickerDialog _time = new TimePickerDialog(getActivity(), ontimeSet, hours, minutes,false){

        @Override
        public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
            // TODO Auto-generated method stub

            try{
                boolean validTime;
                if(hourOfDay < minHour) {
                    validTime = false;
                }
                else if(hourOfDay == minHour) {
                    validTime = minute >= minMinute;
                }
                else if(hourOfDay == maxHour) {
                    validTime = minute <= maxMinute;
                }
                else {
                    validTime = true;
                }

                if(validTime) {
                    hours = hourOfDay;
                    minutes = minute;
                }
                else {
                    updateTime(hours, minutes);
                }

            }catch(Exception e){

            }
        }
    };
    return _time;
}
}

Log-cat错误

updateTime(hours, minutes);时，您从onTimeChanged致电validTime==false。这是你无限循环的根本原因。我不知道为什么它适用于API 15（可能你从未在API 15中使用过这一行）

尝试这样的事情。

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    TimePickerDialog _time = new TimePickerDialog(getActivity(), ontimeSet, hours, minutes,false){
        private boolean ignoreChange = false;

        @Override
        public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
            if(ignoreChange) return;
            try{
                boolean validTime;
                if(hourOfDay < minHour) {
                    validTime = false;
                }
                else if(hourOfDay == minHour) {
                    validTime = minute >= minMinute;
                }
                else if(hourOfDay == maxHour) {
                    validTime = minute <= maxMinute;
                }
                else {
                    validTime = true;
                }

                if(validTime) {
                    hours = hourOfDay;
                    minutes = minute;
                }
                else {
                    try{
                        ignoreChange = true;
                        updateTime(hours, minutes);
                    }finally{
                        ignoreChange = false;
                    }
                }

            }catch(Exception e){
                Log.e(TAG,"Error onTimeChanged",e);
            }
        }
    };
    return _time;
}
