我正在开发一个 android 应用程序，在该应用程序中我使用 GCM 添加通知服务。问题是我想在点击通知时打开特定活动。我不知道如何执行此任务。我还想更改服务器端和客户端的更改。活动名称由服务器提供，然后当我点击通知时活动打开。请帮我 。
I've tried this code.
我试过这个代码。
protected void onMessage(Context context, Intent intent) {
Log.i(TAG,
"Received message. Extras:*************************************************** "
+ intent.getExtras());
// String message = getString(R.string.gcm_message);
// displayMessage(context, message);
// notifies user
String inAction = intent.getAction();
ArrayList<Notify> notifyData = new ArrayList<Notify>();
if (inAction.equals("com.google.android.c2dm.intent.RECEIVE")) {
String json_info = intent.getExtras().getString("data");
Notify notify = new Notify();
if (json_info != null) {
try {
JSONObject jsonObj = new JSONObject(json_info);
notify.setdetail(jsonObj.get("Detail").toString());
notify.setappUpdate(jsonObj.get("App Update").toString());
notify.setcontentUpdate(jsonObj.get("Content Update")
.toString());
notify.setSpecial(jsonObj.get("Special Event").toString());
notify.setSpecialContent(jsonObj.get("splEvtDes")
.toString());
notifyData.add(notify);
} catch (JSONException e) {
// do nothing
return;
}
} else {
notify.setdetail(intent.getStringExtra("Detail"));
notify.setappUpdate(intent.getStringExtra("App Update"));
notify.setcontentUpdate(intent.getStringExtra("Content Update"));
notify.setSpecial(intent.getStringExtra("Special Event"));
notify.setSpecialContent(intent.getStringExtra("splEvtDes"));
notifyData.add(notify);
}
}
String message = null;
if (notifyData.get(0).getappUpdate().equalsIgnoreCase("YES")) {
createNotificationForAppUpdate();
} else if (notifyData.get(0).getcontentUpdate().equalsIgnoreCase("YES")) {
message = notifyData.get(0).getdetail();
generateNotification(context, message);
} else {
System.out
.println("=-----------------------------inside else_________________________");
message = notifyData.get(0).getSpecialContent();
generateNotification(context, message);
}
}

According to your example code,seems you are trying to perform different action in case of Appupdate, contentUpdate and Special content.So according to your code create three method.first for AppUpdate,2nd for content Update and last one for specialcontent.
根据您的示例代码，您似乎正在尝试在 Appupdate、contentUpdate 和特殊内容的情况下执行不同的操作。因此，根据您的代码创建三个方法。第一个用于 AppUpdate，第二个用于内容更新，最后一个用于特殊内容。
String message = null;
if (notifyData.get(0).getappUpdate().equalsIgnoreCase("YES")) {
createNotificationForAppUpdate();
//This will notify for App update
} else if (notifyData.get(0).getcontentUpdate().equalsIgnoreCase("YES")) {
message = notifyData.get(0).getdetail();
//This will notify for Content updte
generateNotification(context, message);
} else {
//This will notify for special content
message = notifyData.get(0).getSpecialContent();
generateNotification(context, message);
}
Method for AppUpdate
AppUpdate的方法
private void createNotificationForAppUpdate()
{
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("Enter here playstore link"));
startActivity(browserIntent);
}
Method for Content Notification.
内容通知的方法。
private void generateNotification(Context context,String message){
int notificationId = 001;
// Build intent for notification content
Intent viewIntent = new Intent(context, YourActivity.class);
viewIntent.putExtra(EXTRA_EVENT_ID, eventId);
PendingIntent viewPendingIntent =
PendingIntent.getActivity(context, 0, viewIntent, 0);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_event)
.setContentTitle("Title")
.setContentText(message)
.setContentIntent(viewPendingIntent);
// Get an instance of the NotificationManager service
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(context);
// Build the notification and issues it with notification manager.
notificationManager.notify(notificationId, notificationBuilder.build());
}
Accordingly create method for special too. Hope this will help GOOD LUCK
因此也为特殊的创造方法。希望这将有助于好运

You can specify any activity to be receiver for push notifications:
您可以指定任何活动作为推送通知的接收者：
<intent-filter>
<action android:name="PACKAGE_NAME.MESSAGE"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
This intent filter for the activity specifies which activity will be launched in response to push notification (PACKAGE_NAME is your Android app package)
此活动的意图过滤器指定将启动哪个活动以响应推送通知（PACKAGE_NAME 是您的 Android 应用程序包）
So you can add this intent filter in your activity which you want to open on the click of Push notification.
因此，您可以在单击推送通知时要打开的活动中添加此意图过滤器。

Mention you specif acitivity (here MainActivity.class) in Pending Intent like this
像这样在 Pending Intent 中提及您指定的活动（此处为 MainActivity.class）
Intent notificationIntent = new Intent(context, MainActivity.class);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

private void notificationMethod(){
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(yourActivity.this)
.setSmallIcon(R.drawable.app_icon)
.setContentTitle("title")
.setContentText("text");
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(yourActivity.this, wantToOpenActivity.this);
// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(yourActivity.this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack( wantToOpenActivity.this);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
int mId=001;;
mNotificationManager.notify(mId, mBuilder.build());
}

<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
I got similar problem and the activity opens after I include "android.intent.action.VIEW".
我遇到了类似的问题，并且在我包含“android.intent.action.VIEW”后活动打开。
