片段

Question

我是使用片段的新手， 我想在用户触摸片段中的Edittext时显示日期选择器 这是我的“选择日期选择器”类（该类通常在我使用活动时起作用）

public class MyEditTextDatePicker implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
EditText _editText;
private int _day;
private int _month;
private int _birthYear;
private Context _context;

public MyEditTextDatePicker(Context context, int editTextViewID){
    Activity act =(Activity) context;
    this._editText = (EditText)act.findViewById(editTextViewID);
    this._editText.setOnClickListener(this);
    this._context = context;
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    _birthYear = year;
    _month = monthOfYear;
    _day = dayOfMonth;
    updateDisplay();
}

@Override
public void onClick(View v) {
    Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
    DatePickerDialog dialog = new DatePickerDialog(_context, this, calendar.get(Calendar.YEAR),
            calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH));
    dialog.show();
}
private void updateDisplay() {
    _editText.setText(new StringBuilder().append(_day).append("/").append(_month + 1)
    .append("/").append(_birthYear).append(" "));
}
}

这就是我在Fragment中使用类的方式

public class HomeFragment extends Fragment {
MyEditTextDatePicker myEditDatePicker;
EditText editTanggal;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_home, container, false);
    editTanggal = (EditText) v.findViewById(R.id.editTanggal);
    myEditDatePicker = new MyEditTextDatePicker(getActivity(),R.id.editTanggal);
    Button btnMulai = (Button)v.findViewById(R.id.btnMulai);
btnMulai.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent bukaOpname = new Intent(getActivity(), OpnameActivity.class);
        startActivity(bukaOpname);
    }
}); return v;  }

}
