Question

下面的代码适用于平板电脑，但不适用于Android手机。我想显示通知。

我的代码是：

            if(trigId.equals("0")){
                 intent=new Intent(this,message_detail.class);
            }else{
                 intent=new Intent(this,appinement_list.class);
            }

            PendingIntent pIntent=PendingIntent.getActivity(this, 0, intent, 0);
            //  nt=new Notification(R.drawable.ic_launcher, "Welco0me", System.currentTimeMillis());
            Notification noti = new Notification.Builder(this)
            .setContentTitle("Notification From EHIQ").setSound(alarmSound).setContentIntent(pIntent)
            .setContentText(" "+Helper_MSGNotification.Subject.get(i)).setSmallIcon(aspl.scorehealth.R.drawable.ic_launcher).build();
            NotificationManager manager=(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
            noti.flags|=Notification.FLAG_AUTO_CANCEL;
            manager.notify(i,noti);

我很困惑实际上有什么问题，请帮助我。

Answer 1

NotificationCompat.Builder是在所有Android版本上创建Notifications的最简单方法。您甚至可以使用Android 4.1提供的功能。如果您的应用在Android＆gt; = 4.1的设备上运行，则会使用新功能，如果在Android＆lt; 4.1上运行，通知将是一个简单的旧通知。

使用Notification.Builder和NotificationCompat.Builder简单替换import android.support.v4.app.NotificationCompat。

要创建简单的通知，请执行以下操作:(请参阅Android API Guide on Notifications）

NotificationCompat.Builder myNotification = new NotificationCompat.Builder(context)
      .setContentTitle("Exercise of Notification!")
      .setContentText("http://android-er.blogspot.com/")
      .setTicker("Notification!")
      .setWhen(System.currentTimeMillis())
      .setContentIntent(pendingIntent)
      .setDefaults(Notification.DEFAULT_SOUND)
      .setAutoCancel(true)
      .setSmallIcon(R.drawable.ic_launcher)
      .build();

尝试这个，

NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(context)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("My notification")
        .setContentText("Hello World!");
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(getApplicationContext(), MYDEMOACTIVITY.class);

// 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(context);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(MYDEMOACTIVITY.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);

// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.build());

在Eclipse中右键单击项目，然后选择Android Tools添加支持库然后安装

将会发生以下变化：

import android.support.v4.app.NotificationCompat;

NotificationCompat.Builder noti = new NotificationCompat.Builder(this);

所有设备中的通知
