开源中国android版代码用了两个广播接收器，一个是静态注册到AndroidManifest.xml中的，一个是动态注册到Main.java这个主activity中的。

    对于静态注册的这个Receiver是类BroadCast.java。用来接收“@我、留言、评论、新粉丝”信息，并在接受到这些信息后发通知提醒。鉴于这部分代码不多，直接上代码：

public void onReceive(Context context, Intent intent) {        String ACTION_NAME = intent.getAction();        if("net.oschina.app.action.APPWIDGET_UPDATE".equals(ACTION_NAME))        {                int atmeCount = intent.getIntExtra("atmeCount", 0);//@我             int msgCount = intent.getIntExtra("msgCount", 0);//留言             int reviewCount = intent.getIntExtra("reviewCount", 0);//评论             int newFansCount = intent.getIntExtra("newFansCount", 0);//新粉丝             int activeCount = atmeCount + reviewCount + msgCount + newFansCount;//信息总数                         //动态-总数             if(Main.bv_active != null){                if(activeCount > 0){                    Main.bv_active.setText(activeCount+"");                    Main.bv_active.show();                }else{                    Main.bv_active.setText("");                    Main.bv_active.hide();                }            }            //@我             if(Main.bv_atme != null){                if(atmeCount > 0){                    Main.bv_atme.setText(atmeCount+"");                    Main.bv_atme.show();                }else{                    Main.bv_atme.setText("");                    Main.bv_atme.hide();                }            }            //评论             if(Main.bv_review != null){                if(reviewCount > 0){                    Main.bv_review.setText(reviewCount+"");                    Main.bv_review.show();                }else{                    Main.bv_review.setText("");                    Main.bv_review.hide();                }            }            //留言             if(Main.bv_message != null){                if(msgCount > 0){                    Main.bv_message.setText(msgCount+"");                    Main.bv_message.show();                }else{                    Main.bv_message.setText("");                    Main.bv_message.hide();                }            }                        //通知栏显示             this.notification(context, activeCount);        }    }

对于动态在Main这个Activity中注册的Receiver是TweetReceiver，用来接收动弹的信息。由于是在Activity内部注册的，因此遵循activity的生命周期，只有在activity启动时才会监听到广播。上代码：

public class TweetReceiver extends BroadcastReceiver {        @Override        public void onReceive(final Context context, Intent intent) {            int what = intent.getIntExtra("MSG_WHAT", 0);                if(what == 1){                Result res = (Result)intent.getSerializableExtra("RESULT");                UIHelper.ToastMessage(context, res.getErrorMessage(), 1000);                if(res.OK()){                    //发送通知广播                     if(res.getNotice() != null){                        UIHelper.sendBroadCast(context, res.getNotice());                    }                    //发完动弹后-刷新最新动弹、我的动弹&最新动态(当前界面必须是动弹|动态)                     if(curTweetCatalog >= 0 && mCurSel == 2) {                        loadLvTweetData(curTweetCatalog, 0, lvTweetHandler, UIHelper.LISTVIEW_ACTION_REFRESH);                    }                        else if(curActiveCatalog == ActiveList.CATALOG_LASTEST && mCurSel == 3) {                        loadLvActiveData(curActiveCatalog, 0, lvActiveHandler, UIHelper.LISTVIEW_ACTION_REFRESH);                    }                }            }else{                            final Tweet tweet = (Tweet)intent.getSerializableExtra("TWEET");                final Handler handler = new Handler(){                    public void handleMessage(Message msg) {                        if(msg.what == 1){                            Result res = (Result)msg.obj;                            UIHelper.ToastMessage(context, res.getErrorMessage(), 1000);                            if(res.OK()){                                //发送通知广播                                 if(res.getNotice() != null){                                    UIHelper.sendBroadCast(context, res.getNotice());                                }                                //发完动弹后-刷新最新、我的动弹&最新动态                                 if(curTweetCatalog >= 0 && mCurSel == 2) {                                    loadLvTweetData(curTweetCatalog, 0, lvTweetHandler, UIHelper.LISTVIEW_ACTION_REFRESH);                                }                                    else if(curActiveCatalog == ActiveList.CATALOG_LASTEST && mCurSel == 3) {                                    loadLvActiveData(curActiveCatalog, 0, lvActiveHandler, UIHelper.LISTVIEW_ACTION_REFRESH);                                }                                if(TweetPub.mContext != null){                                    //清除动弹保存的临时编辑内容                                     appContext.removeProperty(AppConfig.TEMP_TWEET, AppConfig.TEMP_TWEET_IMAGE);                                    ((Activity)TweetPub.mContext).finish();                                }                            }                        }                        else {                            ((AppException)msg.obj).makeToast(context);                            if(TweetPub.mContext != null && TweetPub.mMessage != null)                                TweetPub.mMessage.setVisibility(View.GONE);                        }                    }                };                Thread thread = new Thread(){                    public void run() {                        Message msg =new Message();                        try {                            Result res = appContext.pubTweet(tweet);                            msg.what = 1;                            msg.obj = res;                        } catch (AppException e) {                            e.printStackTrace();                            msg.what = -1;                            msg.obj = e;                        }                        handler.sendMessage(msg);                    }                };                if(TweetPub.mContext != null)                    UIHelper.showResendTweetDialog(TweetPub.mContext, thread);                else                     UIHelper.showResendTweetDialog(context, thread);            }        }    }
