我如何设置tvJobOrder的值。这是我的代码。

public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.main_fragment_layout, container,
                false);

        mSeekBar = (SeekBar) v.findViewById(R.id.mSeekBar);
        mSpinner = (Spinner) v.findViewById(R.id.mSpinner);

        tvJobOrder = (TextView) v.
                findViewById(R.id.tvMainJobOrder);
        setRetainInstance(true);

        id = SharedPreferencesUtils.getString(getActivity(), AppConstants.USER_ID_KEY, "");
        return v;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        if (savedInstanceState == null) {
            new GetJobOrdersTask(new GetJobOrdersTask.TaskCompleteListner() {


                @Override
                public void onTaskComplete(List<GetJobOrderModel> list) {
                    // TODO Auto-generated method stub
                    for (int i = 0; i < list.size(); i++) {

                        mJobOrderList.add(list.get(i).getTitle());
                        mJobOrderIdsList.add(list.get(i).getJobID());
                        mJobOrderIdsList.add(list.get(i).getStatus());
                    }

                    mAdapter.notifyDataSetChanged();
                    SharedPreferencesUtils.saveString(getActivity(),
                            AppConstants.CURRENT_JOB_KEY, mJobOrderIdsList.get(0));
                    tvJobOrder.setText(list.size());
                }
            }, SharedPreferencesUtils.getString(
                    MainFragment.this.getActivity(), AppConstants.USER_ID_KEY,
                    "")).execute();

        mSeekBar.setOnSeekBarChangeListener(this);

        mAdapter = new ArrayAdapter<String>(getActivity(),
                R.layout.custom_spinner_item, mJobOrderList);
        mAdapter.setDropDownViewResource(android.R.layout.simple_list_item_single_choice);
        mSpinner.setAdapter(mAdapter);      
        mSpinner.setOnItemSelectedListener(this);
    }
}

你正在调用方法

 tvJobOrder.setText(list.size());

带有int参数的

，它接受字符串资源ID。在你的情况下，它显然不存在，这不是你想要实际做的。

要解决此问题，请执行以下操作：

tvJobOrder.setText("" + list.size());

如何从asyntask返回settext
