Android - TimePicker分鐘到15

3

你必須寫自己的TimePicker。不確定您是否可以擴展現有的TimePicker並自行處理按鈕事件。

我想我想通了。可能是貧民窟的方式，但...

這是我做的。

start_time.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() { 

      public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 
       updateDisplay(hourOfDay, minute); 
      } 
     }); 

private void updateDisplay(int hourOfDay, int minute) { 
       // do calculation of next time 
       // nextTime = calculation of next time; 

       // the processed boolean is to prevent infinite loop 
     if (!processed) { 
      start_time.setCurrentMinute(nextTime); 
         processed = true; 
     } else { 
         processed = false; 
       } 
    }

以下爲我工作。

首先，在的onCreate：

pickStartTime = (TimePicker)findViewById(R.id.StartTime); 
pickStartTime.setOnTimeChangedListener(mStartTimeChangedListener);

設置OnTimeChangedListener：

private TimePicker.OnTimeChangedListener mStartTimeChangedListener = 
    new TimePicker.OnTimeChangedListener() { 

    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 
     updateDisplay(view, startDate, hourOfDay, minute);   
    } 
};

空OnTimeChangedListener（在評論中updateDisplay說明如下）：

private TimePicker.OnTimeChangedListener mNullTimeChangedListener = 
    new TimePicker.OnTimeChangedListener() { 

    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 

    } 
}; 

private void updateDisplay(TimePicker timePicker, Date date, int hourOfDay, int minute) { 

    // do calculation of next time 
    int nextMinute = 0;  
    if (minute >= 45 && minute <= 59) 
     nextMinute = 45; 
    else if(minute >= 30) 
     nextMinute = 30; 
    else if(minute >= 15) 
     nextMinute = 15; 
    else if(minute > 0) 
     nextMinute = 0; 
    else {   
     nextMinute = 45; 
    } 

    // remove ontimechangedlistener to prevent stackoverflow/infinite loop 
    timePicker.setOnTimeChangedListener(mNullTimeChangedListener); 

    // set minute 
    timePicker.setCurrentMinute(nextMinute); 

    // hook up ontimechangedlistener again 
    timePicker.setOnTimeChangedListener(mStartTimeChangedListener); 

    // update the date variable for use elsewhere in code 
    date.setMinutes(nextMinute); 
}

我才發現我的邏輯存在問題確定分鐘值。使用上面的代碼，「+」按鈕不起作用。當我修復它時，我會發布更新後的代碼。 – 2010-06-24 05:12:54

如果修復了[此錯誤]（http://code.google.com/p/android/issues/detail?id=27653），我們可以刪除一些難看的代碼。 – user250343 2012-04-06 21:43:48

首先我」 D喜歡感謝安德魯克服stackoverflow錯誤（無限循環）。我的邏輯來增加時間b y 15分鐘是這樣的.Declare int previousMinuteSet = 0作爲給定類中的成員變量。

// remove ontimechangedlistener to prevent stackoverflow/infinite loop timePicker.setOnTimeChangedListener(mNullTimeChangedListener);

  if((minute - previousMinuteSet == 1) || (minute - previousMinuteSet == 15) || (minute - previousMinuteSet == -45)) { 
      // set hour 
      timePicker.setCurrentHour((hourOfDay + minute/45) % 12); 
      // set minute 
      timePicker.setCurrentMinute((minute + 14) % 60); 
     } else { 
      // set hour 
      timePicker.setCurrentHour(hourOfDay); 
      // set minute 
      timePicker.setCurrentMinute(minute); 

     } 
     previousMinuteSet = minute; 
     // hook up ontimechangedlistener again 
     timePicker.setOnTimeChangedListener(timePickerChangedListener);

希望，這可能將是others.The代碼我在安德魯的updateDisplay方法取代有幫助的，除了這一切都是相同的。

private void updateDisplay(TimePicker timePicker, int hourOfDay, int minute) { 
    int nextMinute = 0; 

    timePicker.setOnTimeChangedListener(mNullTimeChangedListener); 

    if (minute >= 45 && minute <= 59) 
     nextMinute = 45; 
    else if (minute >= 30) 
     nextMinute = 30; 
    else if (minute >= 15) 
     nextMinute = 15; 
    else if (minute > 0) 
     nextMinute = 0; 
    else { 
     nextMinute = 45; 
    } 

    if (minute - nextMinute == 1) { 
     if (minute >= 45 && minute <= 59) 
      nextMinute = 00; 
     else if(minute >= 30) 
      nextMinute = 45; 
     else if(minute >= 15) 
      nextMinute = 30; 
     else if(minute > 0) 
      nextMinute = 15; 
     else { 
      nextMinute = 15; 
     } 
    } 

    timePicker.setCurrentMinute(nextMinute); 

    timePicker.setOnTimeChangedListener(timePickerChangedListener); 

}

修改+和 - 按鈕的更新顯示方法。其餘的代碼與Andrew Dyer的代碼相同。

這裏是我的版本，在這裏你可以設置時間間隔：

private static final int TIME_PICKER_INTERVAL=15; 
private boolean mIgnoreEvent=false; 

private TimePicker.OnTimeChangedListener mTimePickerListener=new TimePicker.OnTimeChangedListener(){ 
    public void onTimeChanged(TimePicker timePicker, int hourOfDay, int minute){ 
     if (mIgnoreEvent) 
      return; 
     if (minute%TIME_PICKER_INTERVAL!=0){ 
      int minuteFloor=minute-(minute%TIME_PICKER_INTERVAL); 
      minute=minuteFloor + (minute==minuteFloor+1 ? TIME_PICKER_INTERVAL : 0); 
      if (minute==60) 
       minute=0; 
      mIgnoreEvent=true; 
      timePicker.setCurrentMinute(minute); 
      mIgnoreEvent=false; 
     } 

    } 
};

Ankit Thakkar是對的。更確切地說，這是特別的時鐘佈局是有問題的。這是由於minutePicker爲空。我還沒有找到如何解決這個問題。 – PAD 2016-05-24 10:36:17

創建一個XML文件，並將其命名爲activity_time_picker.xml

現在創建活動課這樣

    List<String> displayedValues;

     timePicker.setCurrentHour(0); 
     timePicker.setCurrentMinute(0); 

     setTimePickerInterval(timePicker); 
    } 
@SuppressLint("NewApi") 
    private void setTimePickerInterval(TimePicker timePicker) { 
     try {

       // Field timePickerField = classForid.getField("timePicker"); 

       Field field = classForid.getField("minute"); 
       minutePicker = (NumberPicker) timePicker

       minutePicker.setMinValue(0); 
       minutePicker.setMaxValue(3); 
       displayedValues = new ArrayList<String>(); 
       for (int i = 0; i < 60; i += TIME_PICKER_INTERVAL) {

我已經想出了一個解決方案，基於對這個問題的一些以前的答案，和我自己的一些dditions。這個解決方案明顯地覆蓋了getCurrentMinute和setCurrentMinute，默認情況下，它會返回分鐘索引，而不是分鐘值（例如，如果您的分鐘間隔爲15，並且選擇器顯示的分鐘數爲30，則在沒有此代碼的情況下返回2）。

此解決方案也會翻轉大於最大間隔值的分鐘數（如果間隔爲15，則任何分鐘> 45將將分鐘值設置爲0並遞增小時值）。

注意：此測試和Android 4.4及5.0的工作。

public class CustomIntervalTimePicker extends TimePicker { 

    private static final int TIME_PICKER_MINUTE_INTERVAL = 15; 
    private OnTimeChangedListener timeChangedListener; 

    public CustomIntervalTimePicker(Context context, AttributeSet attrs) { 
     super(context, attrs); 

     try { 
      Class<?> classForId = Class.forName("com.android.internal.R$id"); 
      Field field = classForId.getField("minute"); 

      NumberPicker minuteSpinner = (NumberPicker) this.findViewById(field.getInt(null)); 
      minuteSpinner.setMaxValue((60/TIME_PICKER_MINUTE_INTERVAL) - 1); 
      List<String> displayedValues = new ArrayList<>(); 
      for (int i = 0; i < 60; i += TIME_PICKER_MINUTE_INTERVAL) 
       displayedValues.add(String.format("%02d", i)); 
      minuteSpinner.setDisplayedValues(displayedValues.toArray(new String[displayedValues.size()])); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

    private int maxMinuteIndex() { 
     return (60/TIME_PICKER_MINUTE_INTERVAL) - 1; 
    } 

    @Override 
    public void setOnTimeChangedListener(OnTimeChangedListener onTimeChangedListener) { 
     super.setOnTimeChangedListener(internalTimeChangedListener); 
     this.timeChangedListener = onTimeChangedListener; 
    } 

    @Override 
    public Integer getCurrentMinute() { 
     return super.getCurrentMinute() * TIME_PICKER_MINUTE_INTERVAL; 
    } 

    @Override 
    public void setCurrentMinute(Integer currentMinute) { 
     int cleanMinute = currentMinute/TIME_PICKER_MINUTE_INTERVAL; 
     if(currentMinute % TIME_PICKER_MINUTE_INTERVAL > 0) { 
      if(cleanMinute == maxMinuteIndex()) { 
       cleanMinute = 0; 
       setCurrentHour(getCurrentHour()+1); 
      } else { 
       cleanMinute++; 
      } 
     } 
     super.setCurrentMinute(cleanMinute); 
    } 

    // We want to proxy all the calls to our member variable OnTimeChangedListener with our own 
    // internal listener in order to make sure our overridden getCurrentMinute is called. Without 
    // this some versions of android return the underlying minute index. 
    private OnTimeChangedListener internalTimeChangedListener = new OnTimeChangedListener() { 
     @Override 
     public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 
      timeChangedListener.onTimeChanged(view, getCurrentHour(), getCurrentMinute()); 
     } 
    }; 
}

這是我寫的版本。這是C＃代碼，因爲我使用的是Xamarin，但是我希望任何人都可以將它翻譯成Java，而不是對我來說更難，因爲我需要複製一段Java代碼時執行vica versa翻譯。

這是一個從標準TimePicker有點不同，它的頂部和底部邊框是不連續的，但它是一個缺陷有人會覺得微不足道。

我可以做在使設置自定義間隔幾分鐘更容易，而不是讓你硬編碼在實施間隔值一個更好的工作，但我相信，如果你想很快就可以擦亮這個解決方案！
