android timepicker 设置时间间隔

我的解决方法是继承android TimePicker 类

修改其构造函数

  public TimePicker(Context context, AttributeSet attrs, int defStyle) {
// minute 的部分
        mMinuteSpinner = (NumberPicker) findViewById(R.id.minute);
        mMinuteSpinner.setMinValue(0);
        mMinuteSpinner.setMaxValue(3);
        mMinuteSpinner.setDisplayedValues(new String[]{"0", "15", "30", "45"});
        mMinuteSpinner.setOnLongPressUpdateInterval(100);
}

网络上的其他主流方法是： 

这种方法的缺点在于其前后几个值不正确。具体可以自己写个试试

The following worked for me.

First, in onCreate:

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

Set the OnTimeChangedListener:

private TimePicker.OnTimeChangedListener mStartTimeChangedListener = new TimePicker.OnTimeChangedListener() { public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { updateDisplay(view, startDate, hourOfDay, minute); } };

Null OnTimeChangedListener (explained in comments in updateDisplay below):

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); }
