如何在android中设置自定义分钟间隔timepickerdialog

Answer 1

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;
}

}
};
