Android 4.1.2对话框被调用两次 [英] Android 4.1.2 dialogs are called twice

问题描述

当我打电话来显示一个对话框时，我的应用程序有这个问题，它被称为两次。这只会发生在android 4.1及以上。低版本工作正常，所以我不认为这是任何代码问题。

你以前听过这个问题吗？

这里的代码：

  Button edit =（Button）ad.findViewById（R.id.editBtn）; 
 edit.setTypeface（roboto）; 
 edit.setOnClickListener（new OnClickListener（）{
 
 @Override 
 public void onClick（View v）{
 
 setDate（）; 
 ad.dismiss（）; 
} 
}）; 
 
 ad.show（）; 
 
 ad.setOnDismissListener（new OnDismissListener（）{
 
 @Override 
 public void onDismiss（DialogInterface dialog）{
 shiftingActivity.setPressed（true）; 
 
} 
}）; 
} 
 
 public void setDate（）{
 //初始化并打开设置的日期对话框
 DatePickerDialog setDateDialog = new DatePickerDialog（Shifts.this，
 datePickerListener，dateAndTime.get（Calendar.YEAR），
 dateAndTime.get（Calendar.MONTH），
 dateAndTime.get（Calendar.DAY_OF_MONTH））; 
 
 setDateDialog.setTitle（Set Date）; 
 setDateDialog.show（）; 
 
} 
 
 public void setStartTime（）{
 
 TimePickerDialog setStartTimeDialog = new TimePickerDialog（Shifts.this，
 startTimePicker，dateAndTime.get （Calendar.HOUR），
 dateAndTime.get（Calendar.MINUTE），true）; 
 
 setStartTimeDialog.setTitle（Started At：）; 
 setStartTimeDialog.show（）; 
 
} 
 
 public void setEndTime（）{
 
 TimePickerDialog setEndTimeDialog = new TimePickerDialog（Shifts.this，
 setEndTime，dateAndTime.get （Calendar.HOUR），
 dateAndTime.get（Calendar.MINUTE），true）; 
 setEndTimeDialog.setTitle（Ended：）; 
 setEndTimeDialog.show（）; 
} 
 
 TimePickerDialog.OnTimeSetListener startTimePicker = new TimePickerDialog.OnTimeSetListener（）{
 
 @Override 
 public void onTimeSet（TimePicker view，int hourOfDay，int分钟）{
 startIntHours = hourOfDay; 
 startIntMinutes = minute; 
 editStartTime = String.format（％02d，hourOfDay）+：
 + String.format（％02d，分钟）; 
 setEndTime（）; 
 
} 
}; 
 
 TimePickerDialog.OnTimeSetListener setEndTime = new TimePickerDialog.OnTimeSetListener（）{
 
 @Override 
 public void onTimeSet（TimePicker视图，int hourOfDay，int minute）{
 
 finishIntHours = hourOfDay; 
 finihIntMinutes =分钟; 
 
 if（finishIntHours< startIntHours）{
 finishIntHours = finishIntHours + Utility.HOURS_TIME_UNIT; 
} 
 
 if（finihIntMinutes< startIntMinutes）{
 finihIntMinutes = finihIntMinutes + Utility.MINUTES_TIME_UNIT; 
} 
 
 totalHours = finishIntHours  -  startIntHours; 
 totalMinutes = finihIntMinutes  -  startIntMinutes; 
 Log.i（TotalHours in time picker，+ totalHours）; 
 Log.i（Totalminute in time picker，+ totalMinutes）; 
 
 editEndTime = String.format（％02d，hourOfDay）+：
 + String.format（％02d，minute）; 
 
替换（Shifts.view，Shifts.position）; 
 
} 
}; 
  

解决方案

根据您的代码，这些方法都不会所谓的，因为你不会使用 TimePickerDialogs 。

就是说，有一个与行为有关的已知问题 DatePickerDialog / TimePickerDialog 可能是相关的： http://code.google.com/p/android/issues/detail?id=34833

I have this issue with my app when I call to show a dialog, it is being called twice somehow. This only happens with android 4.1 and above. Lower version works fine so I dont think it's any code issue.

Did you heard\encountered this issue before?

here the code:

Button edit = (Button) ad.findViewById(R.id.editBtn);
        edit.setTypeface(roboto);
        edit.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                setDate();
                ad.dismiss();
            }
        });

        ad.show();

        ad.setOnDismissListener(new OnDismissListener() {

            @Override
            public void onDismiss(DialogInterface dialog) {
                shiftsActivity.setPressed(true);

            }
        });
    }

    public void setDate() {
    // Initialize and open the set date dialog
    DatePickerDialog setDateDialog = new DatePickerDialog(Shifts.this,
            datePickerListener, dateAndTime.get(Calendar.YEAR),
            dateAndTime.get(Calendar.MONTH),
            dateAndTime.get(Calendar.DAY_OF_MONTH));

    setDateDialog.setTitle("Set Date");
    setDateDialog.show();

}

public void setStartTime() {

    TimePickerDialog setStartTimeDialog = new TimePickerDialog(Shifts.this,
            startTimePicker, dateAndTime.get(Calendar.HOUR),
            dateAndTime.get(Calendar.MINUTE), true);

    setStartTimeDialog.setTitle("Started At:");
    setStartTimeDialog.show();

}

public void setEndTime() {

    TimePickerDialog setEndTimeDialog = new TimePickerDialog(Shifts.this,
            setEndTime, dateAndTime.get(Calendar.HOUR),
            dateAndTime.get(Calendar.MINUTE), true);
    setEndTimeDialog.setTitle("Ended:");
    setEndTimeDialog.show();
}

TimePickerDialog.OnTimeSetListener startTimePicker = new TimePickerDialog.OnTimeSetListener() {

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        startIntHours = hourOfDay;
        startIntMinutes = minute;
        editStartTime = String.format("%02d", hourOfDay) + ":"
                + String.format("%02d", minute);
        setEndTime();

    }
};

TimePickerDialog.OnTimeSetListener setEndTime = new TimePickerDialog.OnTimeSetListener() {

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

        finishIntHours = hourOfDay;
        finsihIntMinutes = minute;

        if (finishIntHours < startIntHours) {
            finishIntHours = finishIntHours + Utility.HOURS_TIME_UNIT;
        }

        if (finsihIntMinutes < startIntMinutes) {
            finsihIntMinutes = finsihIntMinutes + Utility.MINUTES_TIME_UNIT;
        }

        totalHours = finishIntHours - startIntHours;
        totalMinutes = finsihIntMinutes - startIntMinutes;
        Log.i("TotalHours in time picker", "" + totalHours);
        Log.i("Totalminute in time picker", "" + totalMinutes);

        editEndTime = String.format("%02d", hourOfDay) + ":"
                + String.format("%02d", minute);

        replace(Shifts.view, Shifts.position);

    }
};

解决方案

According to your code, neither of those methods are ever called, because you never use the TimePickerDialogs.

That being said, there is a known issue related to the behavior of DatePickerDialog/TimePickerDialog that may be relevant: http://code.google.com/p/android/issues/detail?id=34833
