这是我的代码:
NotificationManager mNotificationManager = (NotificationManager) c.getSystemService(ns);
//Instantiate the notification
CharSequence tickerText = "Hello";
long when = System.currentTimeMillis();
Notification.Builder builder = new Notification.Builder(c)
.setTicker(tickerText)
.setWhen(when)
.setContentTitle("Test Notification")
.setContentText(arg1.getStringExtra("info"))
.setSmallIcon(R.drawable.ic_launcher)
.setAutoCancel(true);
Notification notification = builder.getNotification();
mNotificationManager.notify(88, notification);
它可以找到,但不推荐使用Notification notification = builder.getNotification();
。正如我应该做的那样Notification notification = builder.build();
。
问题是Eclipse没有认识到它,这意味着它不会让我编译。该文档清楚地表明build()
存在并且是首选方法,但它不适合我。我想使用不推荐使用的代码,因此非常感谢任何帮助。

请注意import android.app.Notification.Builder;

如果您希望开发版本SDK 较低而不是11,则可以使用此代码代替 android.app.Notification.Builder 类进行创建通知:
private void createNotification(){
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher, "Hello", System.currentTimeMillis());
Intent notificationIntent = new Intent(this, YourActivity.class);
Random r = new Random();
int notificationId = r.nextInt();
notificationIntent.putExtra("n_id", notificationId);
PendingIntent contentIntent = PendingIntent.getActivity(this, notificationId, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.defaults |= Notification.DEFAULT_SOUND;
notification.setLatestEventInfo(this, "Party", "Welcome!", contentIntent);
mNotificationManager.notify(notificationId, notification);
}
您可以在YourActivity中取消此通知,如下所示:
public class YourActivity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_activity);
int notificationId = getIntent().getIntExtra("n_id", -1);
if (notificationId!=-1) {
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.cancel(notificationId);
}
}
}

只有在您针对不具备必需方法/ api 的版本编译应用代码时才会发生这种情况(在您的情况下为build()
)。
如果您正在编译的版本中没有版本,我建议您使用更高版本的Android进行编译,为了向后兼容,您在清单中总是有最小sdk版本。
