如何在Android中设置自定义分钟间隔TimePickerDialog

Answer 1

您好，很高兴能帮助您
private class DurationTimePickDialog extends TimePickerDialog
{
final OnTimeSetListener mCallback;
TimePicker mTimePicker;
final int increment;

public DurationTimePickDialog(Context context, OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView, int increment)
{
super(context, callBack, hourOfDay, minute/increment, is24HourView);
this.mCallback = callBack;
this.increment = increment;
}

@Override
public void onClick(DialogInterface dialog, int which) {
if (mCallback != null && mTimePicker!=null) {
mTimePicker.clearFocus();
mCallback.onTimeSet(mTimePicker, mTimePicker.getCurrentHour(),
mTimePicker.getCurrentMinute()*increment);
}
}

@Override
protected void onStop()
{
// override and do nothing
}

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
try
{
Class<?> rClass = Class.forName("com.android.internal.R$id");
Field timePicker = rClass.getField("timePicker");
this.mTimePicker = (TimePicker)findViewById(timePicker.getInt(null));
Field m = rClass.getField("minute");

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

}

   android如果要修改自定义分钟间隔，一般的做法是重写一个TimePickerDialog，继承它，不过我们也可以通过监听事件来监听数值的改变，来显示自定义的分钟间隔，代码如下：
    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;
       }

   }
};
