在android中以分钟间隔显示TimePicker

我的应用程序显示一个TimePickerDialog来设置一个时间。 我希望timePickerDialog以5分钟的间隔显示分钟。

这与这个代码工作正常：

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; } } 

尽pipe只能以5分钟的间隔select分钟，但timepickerdialog看起来像：

不知道如何分钟也能显示5分钟的范围，如图所示：

我已经search，但无法find解决scheme。

使用下面的自定义类称为CustomTimePickerDialog ，我认为解决您的问题。

 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 mTimePicker; private final OnTimeSetListener mTimeSetListener; public CustomTimePickerDialog(Context context, OnTimeSetListener listener, int hourOfDay, int minute, boolean is24HourView) { super(context, TimePickerDialog.THEME_HOLO_LIGHT, null, hourOfDay, minute / TIME_PICKER_INTERVAL, is24HourView); mTimeSetListener = listener; } @Override public void updateTime(int hourOfDay, int minuteOfHour) { mTimePicker.setCurrentHour(hourOfDay); mTimePicker.setCurrentMinute(minuteOfHour / TIME_PICKER_INTERVAL); } @Override public void onClick(DialogInterface dialog, int which) { switch (which) { case BUTTON_POSITIVE: if (mTimeSetListener != null) { mTimeSetListener.onTimeSet(mTimePicker, mTimePicker.getCurrentHour(), mTimePicker.getCurrentMinute() * TIME_PICKER_INTERVAL); } break; case BUTTON_NEGATIVE: cancel(); break; } } @Override public void onAttachedToWindow() { super.onAttachedToWindow(); try { Class<?> classForid = Class.forName("com.android.internal.R$id"); Field timePickerField = classForid.getField("timePicker"); mTimePicker = (TimePicker) findViewById(timePickerField.getInt(null)); Field field = classForid.getField("minute"); NumberPicker minuteSpinner = (NumberPicker) mTimePicker .findViewById(field.getInt(null)); minuteSpinner.setMinValue(0); minuteSpinner.setMaxValue((60 / TIME_PICKER_INTERVAL) - 1); List<String> displayedValues = new ArrayList<>(); for (int i = 0; i < 60; i += TIME_PICKER_INTERVAL) { displayedValues.add(String.format("%02d", i)); } minuteSpinner.setDisplayedValues(displayedValues .toArray(new String[displayedValues.size()])); } catch (Exception e) { e.printStackTrace(); } } }

有这个真棒库MaterialDateTimePicker创build美丽的风格材料时间select器。

您可以使用以下方法之一来定义您的时间间隔：

• setSelectableTimes（Timepoint [] times）您可以传递一组时间点。 这些值是选取器中唯一有效的select。 setMinTime（Timepoint time）和setMaxTime（Timepoint time）将进一步修剪这个列表。

• setTimeInterval（int hourInterval，int minInterval，int secondInterval）设置TimePickerDialog中可选时间的间隔。 这是setSelectableTimes方便的包装

Answer 3

正如@dedev84所说，你可以用你自己定制的TimePickerDialog来做到这一点。

不过，看看你可以find的源代码：

1. TimePickerDialog是一个框架布局，请参阅此文件 。 它只包含一个TimePicker
2. TimePicker小部件只是一个线性布局，请参阅此文件 。 你可以看到微调是一个NumberPicker

3. 参考NumberPicker的代码，你会发现它有一个公共方法setDisplayedValues（String [] displayedValues）

    /** * Sets the values to be displayed. * * @param displayedValues The displayed values. */ public void setDisplayedValues(String[] displayedValues) 

所以，有了这些信息，我想你可以简单地定制你自己的时间select器对话框，并显示有限的分钟数。

Answer 4

查看TimePickerDialog的代码，它没有出现，他们给你一个方法来直接修改TimePicker然后它显示给用户，你看到“错误的分钟”，你在图片中显示。 请参阅TimePickerDialog.java

我的build议是创build您自己的TimePickerDialog，将devise从Androiddevise中解放出来。 起初可能听起来令人望而生畏，但是

1. 通过这种方式，您可以自定义实现，包括初始化TimePicker值以显示分钟（如上所述），还可以
2. 它实际上不应该很难，Android TimePickerDialog.java本身只有160行，非常易于pipe理。

Answer 5

我已经对上面接受的答案做了一个补充。 问题在于，至less在某些版本的Android中，当您更改选定的时间时，它将用不正确的时间值replace对话框标题。 你不能重写违规方法updateTitle（），但是你可以在onTimeChanged（）方法上拦截调用，不要调用super或者用固定的参数来调用它。

我将setTitle（）方法用非零的stringID键入，但是你可以为布尔本身或其他types设置一个getter / setter。

 @Override public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { if (autoTitle) { // Super will call a private updateTitle() method, so lets make // sure it has the right minute value. super.onTimeChanged(view, hourOfDay, minute * TIME_PICKER_INTERVAL); } else { // do nothing } } @Override public void setTitle(int id) { super.setTitle(id); autoTitle = (id == 0); } ... private boolean autoTitle = true; 

Answer 6

每隔30分钟挣扎一小时。 如果没有看到@Lee的评论，可能会更加挣扎。 所以只需发表完整的30分钟对话代码：

 public class IntervalTimePickerDialog extends TimePickerDialog { private static final String TAG = "IntervalPickerDialog"; private final static int TIME_PICKER_INTERVAL = 30; private TimePicker timePicker; private final OnTimeSetListener callback; private int lastHour = -1; private int lastMinute = -1; public IntervalTimePickerDialog(Context context, int themeId, OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView) { super(context, themeId, callBack, hourOfDay, minute / TIME_PICKER_INTERVAL, is24HourView); lastHour = hourOfDay; lastMinute = minute; 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<>(); 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(); } } @Override public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { super.onTimeChanged(view, hourOfDay, minute); if (lastHour != hourOfDay && lastMinute != minute) { view.setCurrentHour(lastHour); lastMinute = minute; } else { lastHour = hourOfDay; lastMinute = minute; } } 

Answer 7

上面的答案对老版本的Android来说确实很好，但是在Android 7 Nougat中对我来说却不起作用，基本上dateselect器完全改变为使用时钟模式…我将这里提出的代码与https ：//gist.github.com/jeffdgr8/6bc5f990bf0c13a7334ce385d482af9f ，那么它默认设置TimePickerDialog的模式来显示微调控件，它运行的代码只显示15分钟的间隔在我的情况。

Answer 9

基于上面显示的Tanmay Mandal的回答，我已经实现了TimePicker Widget（而不是TimePickerDialog）的解决scheme。 这里的技巧是用一个LinearLayout元素的活动布局replace原始的TimePicker元素，以便以编程方式添加我们的自定义TimePicker。 看下面的例子：

 import java.lang.reflect.Field; import java.util.ArrayList; import java.util.List; import android.content.Context; import android.widget.NumberPicker; import android.widget.TimePicker; public class MyTimePicker extends TimePicker { private static final int TIME_PICKER_INTERVAL = 5; public MyTimePicker(Context context) { super(context); } @Override public Integer getCurrentMinute() { return super.getCurrentMinute()*TIME_PICKER_INTERVAL; } @Override protected void onAttachedToWindow() { super.onAttachedToWindow(); try { Class<?> classForid = Class.forName("com.android.internal.R$id"); Field field = classForid.getField("minute"); NumberPicker mMinuteSpinner = (NumberPicker) 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(); } } } 

而对于我们的活动：

  @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LinearLayout ll = (LinearLayout) findViewById(R.id.myLinearLayout); ll.removeAllViews(); MyTimePicker tp = new MyTimePicker(this); tp.setIs24HourView(true); Calendar cal = Calendar.getInstance(); // Current time tp.setCurrentHour(cal.get(Calendar.HOUR_OF_DAY)); tp.setCurrentMinute(cal.get(Calendar.MINUTE)/5); // Aprox current minute ll.addView(tp); } 

Answer 10

如果你不想在android 5+中使用同一时间select器（不是时钟）对话框，只需更改主题。 您可以直接在构造函数中进行更改：

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