Answer 1

单击您的 EditText 或 Button....

mPickTimeButton.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            // show the time picker dialog
            DialogFragment newFragment = new TimePickerFragment();
            newFragment.show(getSupportFragmentManager(), "timePicker");
        }
    }); // this is on onCreate() method..

@Override
public void onTimePicked(Calendar time)
{
    // display the selected time in the TextView
    mPickedTimeText.setText(DateFormat.format("h:mm a", time));
}

然后创建一个类 TimePickerFragment，该类通过 DialogFragment

扩展

  public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener
{
  private TimePickedListener mListener;

  @Override
 public Dialog onCreateDialog(Bundle savedInstanceState)
  {
    // use the current time as the default values for the picker
    final Calendar c = Calendar.getInstance();
    int hour = c.get(Calendar.HOUR_OF_DAY);
    int minute = c.get(Calendar.MINUTE);

    // create a new instance of TimePickerDialog and return it
    return new TimePickerDialog(getActivity(), this, hour, minute, DateFormat.is24HourFormat(getActivity()));
  }

  @Override
   public void onAttach(Activity activity)
  {
    // when the fragment is initially shown (i.e. attached to the activity), cast the activity to the callback interface type
    super.onAttach(activity);
    try
    {
        mListener = (TimePickedListener) activity;
    }
    catch (ClassCastException e)
    {
        throw new ClassCastException(activity.toString() + " must implement " + TimePickedListener.class.getName());
    }
  }

 @Override
 public void onTimeSet(TimePicker view, int hourOfDay, int minute)
 {
    // when the time is selected, send it to the activity via its callback interface method
    Calendar c = Calendar.getInstance();
    c.set(Calendar.HOUR_OF_DAY, hourOfDay);
    c.set(Calendar.MINUTE, minute);

    mListener.onTimePicked(c);
 }

  public static interface TimePickedListener
 {
    public void onTimePicked(Calendar time);
 }
}

smriti3 我们可以做到，请试试我下面的示例代码，如果您发现任何问题，请告诉我，

 <EditText 
    android:id="@+id/add_TimePicker"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:singleLine="true"
    android:inputType="none"
    android:layout_marginLeft="10dp"
    android:layout_marginRight="10dp"
    android:textColor="#38251f"                   
    android:focusable="false"/>    

并将此示例代码添加到 Activity 中

    Calendar mcurrentDate=Calendar.getInstance();
        int mHour=mcurrentDate.get(Calendar.HOUR_OF_DAY);
        int mMinute=mcurrentDate.get(Calendar.MINUTE);
        EditText mAddTime=(EditText)findViewById(R.id.add_TimePicker);    
        mAddTime.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub          

                        TimePickerDialog mTimePicker=new TimePickerDialog(AddNewMessage.this, new OnTimeSetListener() {                 
                            public void onTimeSet(TimePicker timepicker, int selectedhour, int selectedminute) {
                                // TODO Auto-generated method stub  

                             mAddTime.setText(selectedhour+":"+selectedminute);

                            }
                        },mHour, mMinute,true);
                        mTimePicker.setTitle("Set Time");
                        mTimePicker.show();   
    }
   });

要打开 Time Pcker 对话框，您必须放置一个 Button，或者您应该使用一个 EditText，这样您就可以在 Button 或 EditText 的点击事件上写...

您可以找到示例here。
