android - 如何设置通知的点击监听？

Question

当通过 AlarmManager 启动服务时，我使用以下代码启动通知：

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);

如何为这个项目设置一个意图，以便当用户点击它时，它会启动某个活动？

Answer 1

至于yoshi24的评论，你也许可以像这样设置额外的东西。

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

在处理未决意图之前，您也需要了解这一点

更新 这样的事情对你有用

在你的主要节日

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

在你的活动中

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

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

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

Answer 2

您基本上需要将 Activity 类作为您的意图的一部分放入您的 PendingIntent。目前你的 Intent 是空的。要重定向到新活动，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);

我做的，

• 我添加Intent.FLAG_ACTIVITY_CLEAR_TOP到新的意图

  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);
  

• Oncreate 我做如下：

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