android - 如何在Android Fragment中使用日期选择器？

我在Date Picker中使用了Activity，但是我不知道如何在Fragment中使用它。我正在上载我的活动Date Picker代码。谁能帮助我将代码转换成片段？

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initialize();
    context = getApplicationContext();
    View.OnClickListener listenerDate = new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            final Calendar c = Calendar.getInstance();
            year = c.get(Calendar.YEAR);
            month = c.get(Calendar.MONTH);
            day = c.get(Calendar.DAY_OF_MONTH);
            showDialog(DATE_DIALOG_ID);
        }
    };
    editTextDate.setOnClickListener(listenerDate);
} private void initialize() {
    editTextDate = (EditText) findViewById(R.id.editTextDate);
}private void updateDisplay() {
    currentDate = new StringBuilder().append(day).append(".")
            .append(month + 1).append(".").append(year).toString();
    Log.i("DATE", currentDate);
}
DatePickerDialog.OnDateSetListener myDateSetListener = new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker datePicker, int i, int j, int k) {
        year = i;
        month = j;
        day = k;
        updateDisplay();
        editTextDate.setText(currentDate);
    }
};`

最佳答案

试试这个例子：

public class YourClass extends Fragment {
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
    }

    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
        View view= inflater.inflate(R.layout.your_layout, container, false);
        return view;
    }

    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        edittext.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    showDatePicker();
                }
            });
    }

    private void showDatePicker() {
        DatePickerFragment date = new DatePickerFragment();
        /**
        * Set Up Current Date Into dialog
        */
        Calendar calender = Calendar.getInstance();
        Bundle args = new Bundle();
        args.putInt("year", calender.get(Calendar.YEAR));
        args.putInt("month", calender.get(Calendar.MONTH));
        args.putInt("day", calender.get(Calendar.DAY_OF_MONTH));
        date.setArguments(args);
        /**
        * Set Call back to capture selected date
        */
        date.setCallBack(ondate);
        date.show(getFragmentManager(), "Date Picker");
    }

    OnDateSetListener ondate = new OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {

            edittext.setText(String.valueOf(dayOfMonth) + "-" + String.valueOf(monthOfYear+1)
               + "-" + String.valueOf(year));
        }
    };
}

现在创建类DatePickerFragment：

public class DatePickerFragment extends DialogFragment {
    OnDateSetListener ondateSet;
    private int year, month, day;

    public DatePickerFragment() {}

    public void setCallBack(OnDateSetListener ondate) {
        ondateSet = ondate;
    }

    @SuppressLint("NewApi")
    @Override
    public void setArguments(Bundle args) {
        super.setArguments(args);
        year = args.getInt("year");
        month = args.getInt("month");
        day = args.getInt("day");
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new DatePickerDialog(getActivity(), ondateSet, year, month, day);
    }
}

希望能帮助到你。
