<LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:orientation="horizontal"
                android:padding="3dp" >

                <EditText

BuffetOfferings_MainFragmentActivity.java

public class BuffetOfferings_MainFragmentActivity extends FragmentActivity{

    Button back_button;

    FragmentManager manager;
    FragmentTransaction transaction;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.buffet_offerings_fragment_main_reference);

        Buffet_offerings_breakfast_menu1 breakfast_fragment=new Buffet_offerings_breakfast_menu1();
        Buffet_offerings_lunch_menu1 lunch_fragment=new Buffet_offerings_lunch_menu1();
        Buffet_offerings_dinner_menu1 dinner_fragment=new Buffet_offerings_dinner_menu1();

        manager=getSupportFragmentManager();
        transaction=manager.beginTransaction();

        transaction.add(R.id.BREAKFAST_LAYOUT_ID,breakfast_fragment, "breakfast_menu1_fragment");
        transaction.add(R.id.LUNCH_LAYOUT_ID,lunch_fragment, "lunch_menu1_fragment");
        transaction.add(R.id.DINNER_LAYOUT_ID,dinner_fragment, "dinner_menu1_fragment");

        transaction.commit();



        back_button=(Button) findViewById(R.id.TopNavigationBarRestaurantBuffetOfferingsBackButton);
        back_button.setOnClickListener(new OnClickListener() {

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

            }
        });



    }



}

单击您的 EditText 或按钮....

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));
}

之后创建一个类时间选择器片段这是延伸对话框片段

  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);
 }
}
