timepickerdialog分鐘輸入錯誤

Question

private TimePickerDialog.OnTimeSetListener timeListener = new TimePickerDialog.OnTimeSetListener() { 
    @Override 
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 

     if(hourOfDay < 10){ 
      strHourOfDay = "0" + hourOfDay; 
     } else { strHourOfDay = String.valueOf(hourOfDay);} 

     if(minute < 10){ 
      strMinute = "0" + minute; 
     } else { strMinute = String.valueOf(minute);} 

     period.put("hour",strHourOfDay); 
     period.put("minute",strMinute); 

     periodTime.setText(strHourOfDay + ":" + strMinute); 
    } 
}; 

我使用TimePickerDialog保存小時和分鐘。在strHourOfDay中成功輸入了小時天數的小數點輸入日期。不過分鐘未能在strMinute輸入..

調試結果是在畫面

有什麼錯？

Answer 1

始終使用;

String.valueOf(minute); 

如果你想解析數（爲float，double的int，long），以String。

所以，你的代碼應該是這樣的：

if(minute < 10) { 
     strMinute = "0" + String.valueOf(minute); 
} else { 
     strMinute = String.valueOf(minute); 
}
