Question

我正在使用以下代码通过AlarmManager启动服务时启动通知：

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);

如何设置此项目的意图，以便当用户点击它时，它会启动某项活动？

Answer 1

至于yoshi24的评论，你可以设置这样的额外内容。

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

在进行待定意图

之前，您还需要注意这一点

<强>更新这样的事情会对你有用

你的主要节目

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

在您的活动中

@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类作为意图的一部分放入PendingIntent中。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);

Answer 3

我做到了，

我将Intent.FLAG_ACTIVITY_CLEAR_TOP添加到新意图

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);

Oncreate我这样做：

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

如何设置点击监听器以进行通知？
