Question

如何从Activity中的Fragment触发onOptionsItemSelected（menuItemTransmitMeterReading）单击按钮（btnTransmit）。我需要按钮与menuItem一样。放置所有extraStings并开始新的活动。我是android的新手，片段对我来说非常难。
片段

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.account_detail, container, false);
        if (mItem != null) {
            ((TextView) rootView.findViewById(R.id.account_detail)).setText(mItem.details);
        }
        return rootView;
    }
    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        super.onCreateOptionsMenu(menu, inflater);
        inflater.inflate(R.menu.menu_account, menu);
        menuItemAccountDelete = menu.findItem(R.id.action_account_delete);
        menuItemTransmitMeterReading = menu.findItem(R.id.action_transmit_meter_readings);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.equals(menuItemAccountDelete)) {
            FragmentManager manager = getActivity().getSupportFragmentManager();
            MyDeleteAccountDialog myDialog = new MyDeleteAccountDialog();
            myDialog.LS = mItem.ls;
            myDialog.show(manager, "dialog");
        } else if (item.equals(menuItemTransmitMeterReading)) {
            Intent intent = new Intent(getActivity(), ActivityAccountTransmitMeterReading.class);
            intent.putExtra(ACCOUNT_LS, mItem.ls);
            intent.putExtra(ACCOUNT_NUMBER_OF_ZONES, mItem.MeterZonesCount);
            intent.putExtra(ACCOUNT_LAST_METER_READING, mItem.LastMeterReading);
            intent.putExtra(ACCOUNT_METER_NUMBER_OF_DIGITS, mItem.MeterNumberOfDigits);
            intent.putExtra(ACCOUNT_ADDRESS, mItem.Address);
            intent.putExtra(ACCOUNT_RMES, mItem.R_mes);
            intent.putExtra(ACCOUNT_FKVT1, mItem.FKVT1);
            intent.putExtra(ACCOUNT_FKVT2, mItem.FKVT2);
            intent.putExtra(ACCOUNT_FKVT3, mItem.FKVT3);
            intent.putExtra(ACCOUNT_FIO, mItem.fio);
            if(mItem.LastMeterReading.contains("TEST")){
                FragmentManager manager = getActivity().getSupportFragmentManager();
                MyTransmitMeterReadingDialog myTransmitMeterReadingDialog = new MyTransmitMeterReadingDialog();
                myTransmitMeterReadingDialog.show(manager,"dialog");
            }
            else {
                startActivityForResult(intent, REQUEST_ACCOUNT_TRANSMIT_METER_READING);

            }
        }

        return super.onOptionsItemSelected(item);
    }

就像我在评论中所说，你可以这样做，首先在mainActivity中创建这个方法：

public void startintent(){
Intent intent = new Intent(MainActivity.this, ActivityAccountTransmitMeterReading.class);
            intent.putExtra(ACCOUNT_LS, mItem.ls);
            intent.putExtra(ACCOUNT_NUMBER_OF_ZONES, mItem.MeterZonesCount);
            intent.putExtra(ACCOUNT_LAST_METER_READING, mItem.LastMeterReading);
            intent.putExtra(ACCOUNT_METER_NUMBER_OF_DIGITS, mItem.MeterNumberOfDigits);
            intent.putExtra(ACCOUNT_ADDRESS, mItem.Address);
            intent.putExtra(ACCOUNT_RMES, mItem.R_mes);
            intent.putExtra(ACCOUNT_FKVT1, mItem.FKVT1);
            intent.putExtra(ACCOUNT_FKVT2, mItem.FKVT2);
            intent.putExtra(ACCOUNT_FKVT3, mItem.FKVT3);
            intent.putExtra(ACCOUNT_FIO, mItem.fio);

}

内部按钮onclickListener或onOptionsItemSelected()只需调用：

startintent()

或者如果你想调用片段内的按钮onclickListener或onOptionsItemSelected()：

MainActivity.startintent()

如何在活动按钮单击中触发onOptionsItemSelected（片段）
