如何将意图从片段 class 传递到 android 中的服务 class

Question

我是 android 的新手，我正在学习 android 中的服务，我创建了一个片段，其中有一个 button.On 单击该按钮我需要显示 toast一条消息。

这是我的服务class -

public class BackgroundSoundService extends Service {
private static final String TAG = null;



@Override
public void onCreate() {
    super.onCreate();
    Log.d("tagg", "onCreate: inside service");
    Toast.makeText(getApplication(), "This is my Toast message!", Toast.LENGTH_LONG).show();

}

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}
}

我需要在我的片段 class 中的按钮被点击时吐司消息。这是我的片段 class -

public class ConnectFragment extends Fragment {

Button service_btn;

public ConnectFragment() {
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_connect, container, false);

    service_btn = (Button) rootView.findViewById(R.id.service_button);
    service_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //start_service();
            Intent svc = new Intent(getActivity(), BackgroundSoundService.class);
            try {
                startActivity(svc);

            } catch (Exception e) {
                Log.d("tagg", "start_service:excception " + e);
            }

        }
    });


    return rootView;
}

public void start_service() {
    Intent svc = new Intent(getActivity(), BackgroundSoundService.class);




}

}

现在我得到一个异常

start_service:excception android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.arjunh.navigationdrawer/com.example.arjunh.navigationdrawer.BackgroundSoundService}; have you declared this activity in your AndroidManifest.xml?

Answer 1

在您的 AndroidManifest.xml 文件中添加服务

 <service android:name=".BackgroundSoundService">

然后从这样的片段开始服务

getContext().startService(new Intent(getContext(),BackgroundSoundService.class));

希望对你有所帮助。
