从一个片段广播的意图到服务 [英] Broadcasting an intent from a fragment to a service

问题描述

在一个活动，当我发送的意图，一个服务，我只是使用 sendBroadcast ，但我不能从一个片段做同样的，因为一个片段必须是静态的类。什么是处理这个问题的最好方法？

我已经考虑具有接收的上下文的方法，但是这不会在一个片段的情况下工作。

目前我的code是

 公共静态类ExampleSectionFragment扩展片段{
    公共静态最后弦乐ARG_SECTION_NUMBER =SECTION_NUMBER;    @覆盖
    公共查看onCreateView（LayoutInflater充气器，容器的ViewGroup，
            捆绑savedInstanceState）{
        查看rootView = inflater.inflate（R.layout.fragment_section_example，集装箱，FALSE）;
        捆绑ARGS = getArguments（）;        //例意图广播按钮preSS服务
        rootView.findViewById（R.id.action_start）
                .setOnClickListener（新View.OnClickListener（）{
                    @覆盖
                    公共无效的onClick（查看视图）{
                        意向意图=新意图（RECORDING_INTENT）;
                         sendBroadcast（意向）;
                    }
                }）;
        返回rootView;
    }
}
 

sendBroadcast返回错误在eclipse：

  

无法进行静态引用从类型ContextWrapper

非静态方法sendBroadcast（意向）

解决方案

片段 s的连接到活动 ，这是一个子类上下文 - 更换你的 sendBroadcast 调用（这是试图使用外部类' sendBroadcast ）使用 getActivity（）sendBroadcast - 这将使用上下文与活动的片段正在连接到

In an activity, when I send an intent to a service I just use sendBroadcast, but I cannot do the same from a fragment because a fragment has to be a static class. What is the best way of dealing with this?

I have considered having a method that receives a context, but this wouldn't work in the case of a fragment.

Currently my code is

public static class ExampleSectionFragment extends Fragment {
    public static final String ARG_SECTION_NUMBER = "section_number";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_section_example, container, false);
        Bundle args = getArguments();

        //Example intent to broadcast to service on button press
        rootView.findViewById(R.id.action_start)
                .setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        Intent intent = new Intent(RECORDING_INTENT);
                         sendBroadcast(intent);
                    }
                });
        return rootView;
    }
}

sendBroadcast returns the error in eclipse:

Cannot make a static reference to the non-static method sendBroadcast(Intent) from the type ContextWrapper

解决方案

Fragments are attached to an Activity, which is a subclass of Context - replace your sendBroadcast call (which is attempting to use the outer class' sendBroadcast) with getActivity().sendBroadcast - this will use the Context associated with Activity the Fragment is currently attached to.
