我的应用程序显示一个TimePickerDialog设定一个时间。 我想，该timePickerDialog显示分钟，5分钟的间隔。 这正常工作与此code：

My application show a TimePickerDialog to set a time. I want that the timePickerDialog show the minutes with an interval of 5 minutes. this works fine with this code:

private final int TIME_PICKER_INTERVAL=5;
private boolean mIgnoreEvent=false;
…
    public TimePickerDialogs(Context arg0, OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView) {
    super(arg0, callBack, hourOfDay, minute, is24HourView);

    formato=Statics.formato;
}

@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
    //super.onTimeChanged(arg0, arg1, arg2);

    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;
        view.setCurrentMinute(minute);
        mIgnoreEvent=false;
    }
}

虽然只有几分钟的路程可以用五分钟的时间来选择，在timepickerdialog是这样的：

Although only minutes can be selected with an interval of five minutes, the timepickerdialog looks like:

不知道怎么纪要还显示5分钟的范围内，因为在这样的画面：

do not know how the minutes also show the range of 5 minutes, as in this picture:

我已经搜查，但找不到解决办法。

I have searched but can not find the solution.

我AP preciate任何帮助。

I appreciate any help.

非常感谢你提前。

使用名为 CustomTimePickerDialog 以下的自定义类，我认为解决您的问题。

Use the following the custom class called CustomTimePickerDialog, which I think solve your problem.

import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;

import android.app.TimePickerDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.widget.NumberPicker;
import android.widget.TimePicker;

public class CustomTimePickerDialog extends TimePickerDialog {

    private final static int TIME_PICKER_INTERVAL = 5;
    private TimePicker timePicker;
    private final OnTimeSetListener callback;

    public CustomTimePickerDialog(Context context, OnTimeSetListener callBack,
            int hourOfDay, int minute, boolean is24HourView) {
        super(context, TimePickerDialog.THEME_HOLO_LIGHT, callBack, hourOfDay, minute / TIME_PICKER_INTERVAL,
                is24HourView);
        this.callback = callBack;
    }

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

    @Override
    protected void onStop() {
    }

    @Override
    public void onAttachedToWindow() {
        super.onAttachedToWindow();
        try {
            Class<?> classForid = Class.forName("com.android.internal.R$id");
            Field timePickerField = classForid.getField("timePicker");
            this.timePicker = (TimePicker) findViewById(timePickerField
                    .getInt(null));
            Field field = classForid.getField("minute");

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

    }

}
