带有 TimePicker 的 Android Recycler View Adapter

Question

我有一个带有 RecyclerView 的片段，用户可以在其中引入一个或多个时区，选择开始和结束时间。

当用户每小时点击一次时，会出现时间选择器：

选择小时后，我想将文本小时更改为用户选择的时间。我从 RecyclerView 适配器显示 timePicker，但我不知道如何从 onTimeSet 传递来修改小时的 textView。据我所知，它必须在 RecyclerView 适配器内。

我终于找到了解决方案。所有这些都发生在 RecyclerView Adapter 内部。我向 textView 添加了一个 onClick 侦听器。然后我在创建对话框片段时传递视图。

onBindViewHolder 内部：

horarioViewHolder.mFromTime.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                DialogFragment newFragment = new TimePickerFragment(v);
                newFragment.show(((ChefAltaUnoActivity)mContext).getSupportFragmentManager(), "timePicker");

            }
        });

TimePickerFragment 内部：

public static class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener {


    private View mView;

    public  TimePickerFragment(View view) {
        mView = view;
    }



    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current time as the default values for the picker


        final Calendar c = Calendar.getInstance();
        int hour = c.get(Calendar.HOUR_OF_DAY);
        int minute = c.get(Calendar.MINUTE);


        TimePickerDialog timePicker = new TimePickerDialog(getActivity(), R.style.CustomTimePickerDialogTheme, this, hour, minute,
                DateFormat.is24HourFormat(getActivity()));


        // Create a new instance of TimePickerDialog and return it
        return timePicker;
    }

    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {


        ((TextView) mView).setText("format the time text as you want.");

    }

}
