Question

我正在尝试启动通知点击活动，但它永远不会开始。以下是我发送通知的代码：

Intent notificationIntent = new Intent(this, MainActivity.class);
        notificationIntent.putExtra("Notification", type);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK|Intent.FLAG_ACTIVITY_NEW_TASK);
        PendingIntent pIntent = PendingIntent.getActivity(this, 0,notificationIntent, 0);
        Notification n = new Notification.Builder(this)
                .setContentTitle(title)
                .setContentText(type)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pIntent)
                .build();
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        notificationManager.notify(0, n);

点击通知我从未接到过该活动的电话。

尝试这一个 将Splash_Activity.class替换为您的活动，并确保您已在Manifest.xml
中注册此课程

 protected void displayNotification(Context context, String[] strContent) {
            try {
                int numMessages = 0;

                /* Invoking the default notification service */
                NotificationCompat.Builder  mBuilder = new NotificationCompat.Builder(this);

                mBuilder.setContentTitle("New "+strContent[0].trim());
                mBuilder.setContentText("You've received new "+strContent[0].trim());
                mBuilder.setTicker("New "+strContent[0].trim()+" Alert!");
                mBuilder.setSmallIcon(R.drawable.ic_notif);
                mBuilder.setAutoCancel(true);
                mBuilder.setColor(context.getResources().getColor(R.color.ColorPrimary));
                mBuilder.setVisibility(Notification.VISIBILITY_PUBLIC);
                mBuilder.setDefaults(Notification.DEFAULT_ALL);
                mBuilder.setVibrate(new long[] {1000, 1000, 1000, 1000, 1000});         

                mBuilder.setLights(Color.RED, 3000, 3000);
             mBuilder.setNumber(++numMessages);

            NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();

                String[] events = new String[strContent.length-1];
                for(int i=0; i<strContent.length-1; i++){
                    events[i] = new String(strContent[i+1].trim());
                }

                inboxStyle.setBigContentTitle("New "+strContent[0].trim()+" received!");

                for (int i=0; i < events.length; i++) {
                    inboxStyle.addLine(events[i]);
                }

                mBuilder.setStyle(inboxStyle);

                /* Creates an explicit intent for an Activity in your app */
                Intent resultIntent = new Intent(this, Splash_Activity.class);


                TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
                stackBuilder.addParentStack(Splash_Activity.class);

                /* 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) getSystemService(Context.NOTIFICATION_SERVICE);

                /* notificationID allows you to update the notification later on. */
                mNotificationManager.notify(9999, mBuilder.build());
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }
        }

当您想要通知时，请调用此方法

public void showNotification() {
        PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, ShowNotificationDetailActivity.class), 0);
        Resources r = getResources();
        Notification notification = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.main)
                .setContentTitle("title")
                .setContentText("Welcome")
                .setContentIntent(pi)
                .setAutoCancel(true)
                .build();
        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        notificationManager.notify(0, notification);
    }

创建一个这样的类，让你的课程进入活动

public class ShowNotificationDetailActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(this, Main.class);
        startActivity(intent);
    }
}

通知意图不启动Actiivty android
