訂戶類... TaskAdapter沒有公共方法，名爲onEvent

我在EventBus上遇到了一些麻煩。特別是當我試圖運行它給我的錯誤訂戶類... TaskAdapter沒有公共方法，名爲onEvent

10-16 22:59:38.277: E/AndroidRuntime(1175): Caused by: de.greenrobot.event. 
EventBusException: Subscriber class com.example.listtame.UI.TaskAdapter 
has no public methods called onEvent

應用但它確實有這樣的一個公共方法如下所示。有誰知道爲什麼事件總線將拋出此異常？

謝謝！

package com.example.listtame.UI; 

import java.util.Collections; 
import java.util.List; 

import com.example.listtame.R; 
import com.example.listtame.Activities.TaskList; 
import com.example.listtame.CustomObj.Task; 
import com.example.listtame.Events.TaskListFetchedEvent; 

import de.greenrobot.event.EventBus; 



import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageView; 
import android.widget.TextView; 

public class TaskAdapter extends BaseAdapter { 

    private List<Task> tasks = Collections.emptyList(); 

    private final Context context; 



    public TaskAdapter(Context context) { 
     this.context = context; 
     EventBus.getDefault().register(this); 

    } 

    public void OnEventMainThread(TaskListFetchedEvent e) { 
     this.tasks = TaskListFetchedEvent.mTaskList; 
     notifyDataSetChanged(); 
    } 


    private static class ViewHolder { 
     public final ImageView task_image; 
     public final TextView task_text; 

     public ViewHolder(ImageView task_image, TextView task_text) { 
      this.task_image = task_image; 
      this.task_text = task_text; 
     } 
    } 


    public void updateTasks(List<Task> tasks) { 
     this.tasks = tasks; 
     notifyDataSetChanged(); 
    } 

    @Override 
    public int getCount() { 
     return tasks.size(); 
    } 

    @Override 
    public Task getItem(int position) { 
     return tasks.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 
     ImageView task_image; 
     TextView task_text; 
     if (convertView == null) { 
      convertView = LayoutInflater.from(context) 
       .inflate(R.layout.task_box, parent, false); 
      task_image = (ImageView) convertView.findViewById(R.id.task_icon); 
      task_text = (TextView) convertView.findViewById(R.id.task_text); 
      convertView.setTag(new ViewHolder(task_image, task_text)); 
     } else { 
      ViewHolder viewHolder = (ViewHolder) convertView.getTag(); 
      task_image = viewHolder.task_image; 
      task_text = viewHolder.task_text; 
     } 

     Task task = getItem(position); 
     task_text.setText(task.getText()); 
     task_image.setImageResource(R.drawable.ic_debug); 

     return convertView; 
    } 


}

我也嘗試將OnEventMainThread方法更改爲簡單的OnEvent。有道理我得到同樣的例外。完整的LogCat張貼在下面，以防萬一有人好奇。

編輯***********************************

邁克爾已經發佈下面的解決方案。 onEvent需要onEvent而不是OnEvent。

你是通過反射調用這個方法嗎？如果是這樣，你可以發佈反饋電話的代碼嗎？ – 2014-10-16 23:17:23

按'這個方法'我假設你正在談論OnEventMainThread方法？我已經粘貼了。 – AnnonAshera 2014-10-16 23:23:09

看完github上的greenrobot EventBus代碼後，我發現他們希望你用「onEvent」+一個可選的修飾符來聲明你的事件回調，我發現你正在做的事情。

但是，您正在用大寫'O'開始您的方法。將您的方法重命名爲onEventMainThread，我敢打賭它會起作用！

現在看起來很明顯。非常感謝！這解決了它！你搖滾邁克爾！ – AnnonAshera 2014-10-17 00:45:46

謝謝。請記住接受答案，如果它幫助你。 – 2014-10-17 01:34:48

已接受。祝你有個好的一天！ – AnnonAshera 2014-10-17 02:23:26
