问题描述
我有我的应用程序这个问题时，我打电话给显示对话框中，它被称为莫名其妙地两次。这仅与Android 4.1及更高发生。所以我不认为这是任何code问题低版本工作正常。
你有没有听说过\\遇到过这个问题？
这里的code：
按钮编辑=（按钮）ad.findViewById（R.id.editBtn）;
edit.setTypeface（的Roboto）;
edit.setOnClickListener（新OnClickListener（）{ @覆盖
公共无效的onClick（视图v）{ 的setDate（）;
ad.dismiss（）;
}
}）; ad.show（）; ad.setOnDismissListener（新OnDismissListener（）{ @覆盖
公共无效onDismiss（DialogInterface对话）{
shiftsActivity.set pressed（真）; }
}）;
} 公共无效的setDate（）{
//初始化并打开设置对话框日期
DatePickerDialog setDateDialog =新DatePickerDialog（Shifts.this，
datePickerListener，dateAndTime.get（Calendar.YEAR）
dateAndTime.get（的Calendar.MONTH）
dateAndTime.get（Calendar.DAY_OF_MONTH））; setDateDialog.setTitle（设定日期）;
setDateDialog.show（）;}公共无效setStartTime（）{ TimePickerDialog setStartTimeDialog =新TimePickerDialog（Shifts.this，
startTimePicker，dateAndTime.get（Calendar.HOUR）
dateAndTime.get（Calendar.MINUTE），TRUE）; setStartTimeDialog.setTitle（开始时间：）;
setStartTimeDialog.show（）;}公共无效setEndTime（）{ TimePickerDialog setEndTimeDialog =新TimePickerDialog（Shifts.this，
setEndTime，dateAndTime.get（Calendar.HOUR）
dateAndTime.get（Calendar.MINUTE），TRUE）;
setEndTimeDialog.setTitle（结束：）;
setEndTimeDialog.show（）;
}TimePickerDialog.OnTimeSetListener startTimePicker =新TimePickerDialog.OnTimeSetListener（）{ @覆盖
公共无效onTimeSet（TimePicker观点，诠释HOUROFDAY，分整型）{
startIntHours = HOUROFDAY;
startIntMinutes =分钟;
editStartTime =的String.format（％02D，HOUROFDAY）+：
+的String.format（％02D，分）;
setEndTime（）; }
};TimePickerDialog.OnTimeSetListener setEndTime =新TimePickerDialog.OnTimeSetListener（）{ @覆盖
公共无效onTimeSet（TimePicker观点，诠释HOUROFDAY，分整型）{ finishIntHours = HOUROFDAY;
finsihIntMinutes =分钟; 如果（finishIntHours＆LT; startIntHours）{
finishIntHours = finishIntHours + Utility.HOURS_TIME_UNIT;
} 如果（finsihIntMinutes＆LT; startIntMinutes）{
finsihIntMinutes = finsihIntMinutes + Utility.MINUTES_TIME_UNIT;
} totalHours = finishIntHours - startIntHours;
totalMinutes = finsihIntMinutes - startIntMinutes;
Log.i（TotalHours在时间选择器，+ totalHours）;
Log.i（Totalminute在时间选择器，+ totalMinutes）; editEndTime =的String.format（％02D，HOUROFDAY）+：
+的String.format（％02D，分）; 更换（Shifts.view，Shifts.position）; }
};
解决方案
根据您的code，无论这些方法是不断呼吁，因为你永远不使用 TimePickerDialogs 。
话虽这么说，有相关的 DatePickerDialog / TimePickerDialog 的行为可能相关的已知问题：<一href=\"http://$c$c.google.com/p/android/issues/detail?id=34833\">http://$c$c.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
