Click on your EditText or 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));
}

After that create a class TimePickerFragment which is extends with DialogFragment

  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);
 }
}

We can do it smriti3 ,Please try my below sample code and let me know if you found any issues,

 <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"/>    

And Add this sample code in within Activity

    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();   
    }
   });

For opening Time Pcker Dialog you have to put one Button OR You should use one EditText so you can write on click event of Button or EditText...

You can find example here.
