Question

我有一个datepicker对话框和listview。我希望在onclick时显示对话框，但onClick中showdialog()的方法已弃用。我不知道我的错误在哪里。

知道怎么解决吗？

        iv = (ImageView) rootView.findViewById(R.id.imageView1);

        profile_pics.recycle();

        return rootView;
    }

    @Override
    public void onClick(View v)
    {
        getActivity().showDialog(0);
    }

    @Deprecated
    protected Dialog onCreateDialog(int id) {
        return new DatePickerDialog(getActivity(), datePickerListener, year, month, day);
    }

    private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
        public void onDateSet(DatePicker view, int selectedYear,
                              int selectedMonth, int selectedDay) {
            et.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                    + selectedYear);
        }
    };
}

我认为你需要阻止

protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(getActivity(), datePickerListener, year, month, day);
}

在活动中，您正在调用showDialog()。

showdialog（）不在片段中工作
