如何设置通知的点击监听器？

Question

我使用下面的代码时启动一个服务已启动通过AlarmManager通知：

nm = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); 
CharSequence from = "App"; 
CharSequence message = "Getting Latest Info..."; 
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(), 0); 
Notification notif = new Notification(R.drawable.icon, 
    "Getting Latest Info...", System.currentTimeMillis()); 
notif.setLatestEventInfo(this, from, message, contentIntent); 
nm.notify(1, notif); 

如何设置意图为这个项目，这样当用户点击它，它会推出一定的活动？

Answer 1

您基本上需要将Activity类作为您的意图的一部分放入PendingIntent。目前你的意图是空的。重定向到新的活动，它应该是：

// This line of yours should contain the activity that you want to launch. 
// You are currently just passing empty new Intent() 
PendingIntent contentIntent = 
    PendingIntent.getActivity(this, 0, new Intent(this, MyActivity.class), 0); 

Answer 2

至于yoshi24的评论，你可以设置额外这样。

final Intent intent = new Intent(this, MyActivity.class); 
intent.setData(data); 
intent.putExtra("key", "value"); 
final PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0); 

您需要以及准备挂起意图

UPDATE 一些像这样的事情会为你

INT您mainfest

工作之前，要意识到这一点

<activity android:name=".MyActivity" android:launchMode="singleTop" ... /> 

您的活动

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    processIntent(getIntent()); 
} 

@Override 
protected void onNewIntent(Intent intent) {  
    processIntent(intent); 
}; 

private void processIntent(Intent intent){ 
    //get your extras 
}

我做到了，

• 我添加Intent.FLAG_ACTIVITY_CLEAR_TOP新意图

  NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
  Notification notification = new Notification(R.drawable.ic_launcher, 
       "A new notification", System.currentTimeMillis()); 
  // Hide the notification after its selected 
  notification.flags |= Notification.FLAG_AUTO_CANCEL; 
  
  Intent intent = new Intent(this, NoficationDemoActivity.class); 
  intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
  Bundle bundle = new Bundle(); 
  bundle.putString("buzz", "buzz"); 
  intent.putExtras(bundle); 
  PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0); 
  notification.setLatestEventInfo(this, "This is the title", 
       "This is the text", activity); 
  notification.number += 1; 
  notificationManager.notify(0, notification); 
  

• 的onCreate我如下操作：

  super.onCreate(savedInstanceState); 
  setContentView(R.layout.main); 
  if(getIntent().getExtras()!=null){ 
      Toast.makeText(this, "Click", Toast.LENGTH_SHORT).show(); 
  }
