Use this :
public class MainActivity extends Activity {

    private TextView tvDisplayDate;
    private DatePicker dpResult;    

    private int mYear;
    private int mMonth;
    private int mDay;
    static final int DATE_DIALOG_ID = 1;

 //these variables are used to set max years need to set on Date Picker dialog...
    int minYear1 = 2000; 
    int minMonth1 = 0;//0-january , 1-february , 2-march..
    int minDay1 =1;

    int minYear = minYear1;
    int minMonth = minMonth1;
    int minDay = minDay1;

    //these are the minimum dates to set Datepicker..
    private int year;
    private int month;
    private int day;    

    public String dateOutput=null;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH); 

            setCurrentDateOnView();

        Button pickDate = (Button) findViewById(R.id.btnChangeDate);
        pickDate.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                        showDialog(DATE_DIALOG_ID);
                }
        });

    }

    // display current date
    public void setCurrentDateOnView() {

        System.out.println("----------setCurrentDateOnView()-----------");

        tvDisplayDate = (TextView) findViewById(R.id.tvDate);
        dpResult = (DatePicker) findViewById(R.id.dpResult);

        final Calendar c = Calendar.getInstance();
        year = c.get(Calendar.YEAR);
        month = c.get(Calendar.MONTH);
        day = c.get(Calendar.DAY_OF_MONTH);

        // set current date into textview
        tvDisplayDate.setText(new StringBuilder()
                // Month is 0 based, just add 1
                .append(month + 1).append("-").append(day).append("-")
                .append(year).append(" "));

        // set current date into datepicker
        dpResult.init(year, month, day, null);
    }


    //this was the main part in program to Restrict the DatePicker Dialog  to only its current date.
