多个notification引发的问题

最近使用notification，对多个notification引发的问题总结如下(只是我碰到的):

1.多个通知间，点其中一个可能取到另一个通知的内容(通知的添加的代码相似)

2.多个通知间，点击完其中一个通知，导致另外一个通知无法点击

下面贴上自己的一段测试代码：

public class NotificationActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button) findViewById(R.id.button1); EditText editText = (EditText) findViewById(R.id.editText1); editText.setHeight(100); button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubaddNotification(2);try {Thread.sleep(2000);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}addNotification(1);}}); } /** * 添加一个notification */ private void addNotification(int id){ NotificationManager nm = (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE); Notification notification = new Notification(R.drawable.icon, "hello,here", System.currentTimeMillis()); notification.flags = Notification.FLAG_AUTO_CANCEL; Intent intent = new Intent(this, Notification2Activity.class); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); intent.putExtra("id", id + ""); PendingIntent contentIntent = PendingIntent.getActivity(this, id, intent, PendingIntent.FLAG_UPDATE_CURRENT); notification.setLatestEventInfo(this, "有新消息", id + "", contentIntent); nm.notify(id, notification); }}

public class Notification2Activity extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.main2);Log.i("Notification2Activity 收到id:", getIntent().getStringExtra("id"));}}

这是我测试通过，没问题后的代码.

现在说说上述两个问题的症状在哪?

1.PendingIntent.FLAG_UPDATE_CURRENT，如果设置PendingIntent.FLAG_ONE_SHOT,PendingIntent 紧紧只能被点击一次.

PendingIntent.FLAG_UPDATE_CURRENT具体代表啥,去看源码吧.

2.

public static PendingIntent getActivity(Context context, int requestCode, Intent intent, int flags) { String packageName = context.getPackageName(); String resolvedType = intent != null ? intent.resolveTypeIfNeeded( context.getContentResolver()) : null; try { IIntentSender target = ActivityManagerNative.getDefault().getIntentSender( IActivityManager.INTENT_SENDER_ACTIVITY, packageName, null, null, requestCode, intent, resolvedType, flags); return target != null ? new PendingIntent(target) : null; } catch (RemoteException e) { } return null; }

这是获取PendingIntent的源码,

第二个参数requestCode,代表着发送者的一个标识,用来区分不同通知的接收者.

所以这地方需要设置下,不能相同,否则产生前面提到的第一个的问题
