public class MainActivity extends AppCompatActivity  {
    Calendar ca = Calendar.getInstance();
    int  mYear = ca.get(Calendar.YEAR);

    @Override
    @RequiresApi(api = Build.VERSION_CODES.N)
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month1 = c.get(Calendar.MONTH);
        final int day = c.get(Calendar.DAY_OF_MONTH);
        new DatePickerDialog(this, DatePickerDialog.THEME_HOLO_LIGHT, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year1, int month1, int dayOfMonth) {
                Toast.makeText(MainActivity.this,year1+"年"+(month1+1)+"月"+dayOfMonth+"日",Toast.LENGTH_LONG).show();  //当前选中的日期
            }
        }, year, month1, day).show();    //  系统的当前日期
    }
}
