广播接收器在从服务到片段的改造2呼叫的响应中发送广播的问题

问题描述 投票:0回答:1

这是我发送广播的代码,我在这里更改本地数据库表,然后发送广播:

for (int i = 0; i < forms.length(); i++) {
 retrofit2.Call<SubmitFormResponse> call;
 call = RetrofitClass.getInstance().getWebRequestsInstance().formSubmitWitoutImages(tinyDB.getString(Constants.token), bodyRequest);

 call.enqueue(new Callback<SubmitFormResponse>() {
                    @Override
                    public void onResponse(Call<SubmitFormResponse> call, Response<SubmitFormResponse> response) {
                        if (response.isSuccessful()) {
                            formIds.add(formId);
                            QueueModel model = databaseHandler.getQueueIncidenceStateOnIncidenceID(task_id);
                            model.setNumSubmitted(++numSubmitted);
                            databaseHandler.updateQueuedIncidenceStateOnRunId(model);
//                            updateUI.updateUI(databaseHandler.getAllQueuedIncidences());
                            UploaderService.this.sendBroadcast(new Intent(BROADCAST_ACTION));
                        }
                    }

                    @Override
                    public void onFailure(Call<SubmitFormResponse> call, Throwable t) {
                        t.printStackTrace();
                    }
                });
}

接收广播时,我将从更新的数据库表中获取列表,然后使用片段中的notifyDataSetChanged()重新初始化适配器。这是接收广播的代码:

        @Override
        public void onReceive(Context context, Intent intent) {
            Log.e("CALLED", "Intent passed");

//            pullToRefresh.setRefreshing(true);
            if (adapter != null) {
                list = databaseHandler.getAllQueuedIncidences();
                if (list.size() == 0) {
                    tvNoPendingUploads.setVisibility(View.VISIBLE);
                    rvPendingUploads.setVisibility(View.GONE);
                } else {
                    tvNoPendingUploads.setVisibility(View.GONE);
                    rvPendingUploads.setVisibility(View.VISIBLE);
                    adapter.setItems(list);
                    adapter.notifyDataSetChanged();
                }
            } else {

                list = databaseHandler.getAllQueuedIncidences();
                Log.e("Up", databaseHandler.getAllQueuedIncidences().size() + "");

                if (list.size() == 0) {
                    tvNoPendingUploads.setVisibility(View.VISIBLE);
                    rvPendingUploads.setVisibility(View.GONE);
                } else {
                    tvNoPendingUploads.setVisibility(View.GONE);
                    rvPendingUploads.setVisibility(View.VISIBLE);
                    adapter = new AdapterPendingUploads(list, getActivity());
                    rvPendingUploads.setLayoutManager(manager);
                    rvPendingUploads.setAdapter(adapter);
                }
            }
//            pullToRefresh.setRefreshing(false);

        }
    }; 

接收者已在onCreateView()中注册,而未​​在onDestroy()中注册:

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.fragment_pending_uploads, container, false);

        init(view);
        clickListeners();
        getActivity().registerReceiver(broadcastReceiver, new IntentFilter(
                BROADCAST_ACTION));
        return view;
    }

@Override
    public void onDestroy() {
        getActivity().unregisterReceiver(broadcastReceiver);

        super.onDestroy();
    } 

sendBroadcast()不会立即调用BroadcastReceiver的onRecieve(),而是等待循环结束,其中sendBroadcast()被调用了n次,最后onRecieve()被调用了n-次数,连续不断。我需要在点击每个API之后更新UI。击中每个API后,应该同时调用sendBroadcast()和onRecieve()。请告诉我我在做什么错?

您可以尝试使用EventBus库。
