MainActivity.java

public class MainActivity extends FragmentActivity {

    EditText edt;
    EditText edt2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        edt=(EditText)findViewById(R.id.editText1);
        edt2=(EditText)findViewById(R.id.editText2);   
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
        Calendar c = Calendar.getInstance();
        Calendar c1=Calendar.getInstance();
        c1.setTime(new Date());
        c.setTime(new Date()); // Now use today date.
        c.add(Calendar.DATE, 7); // Adding 7 days
        String ToDate = sdf.format(c.getTime());
        String FromDate = sdf.format(c1.getTime());
        edt2.setText(FromDate);
        edt.setText(ToDate);
    }



     public void selectDate(View view) {
            DialogFragment newFragment = new SelectDateFragment();
            newFragment.show(getSupportFragmentManager(), "DatePicker");
        }
        public void populateSetDate(int year, int month, int day) {
            edt2 = (EditText)findViewById(R.id.editText1);
            edt2.setText(day+"/"+month+"/"+year);
        }
        public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
            @Override
            public Dialog onCreateDialog(Bundle savedInstanceState) {
                final Calendar calendar = Calendar.getInstance();
                int yy = calendar.get(Calendar.YEAR);
                int mm = calendar.get(Calendar.MONTH);
                int dd = calendar.get(Calendar.DAY_OF_MONTH);
                return new DatePickerDialog(getActivity(), this, yy, mm, dd);
            }

            public void onDateSet(DatePicker view, int yy, int mm, int dd) {
                populateSetDate(yy, dd, mm+1);
            }
        }   
}

您只需实现 Edittext onClickListner onClick() 事件:

edt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
               // new DatePickerDialog(ProximityActivity.this, dateD, myCalendar
                        //.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                        //myCalendar.get(Calendar.DAY_OF_MONTH)).show();

                      //Load your DiaglogFragment Over here
            }
        });
