我需要创建多个状态栏通知.当我拉下状态栏时,应该将多个通知图标显示为列表.每个通知图标都应显示下一页显示的单独数据.我怎么能这样做？

我的代码:

public class SimpleNotification extends Activity {

private NotificationManager mNotificationManager;
private int SIMPLE_NOTFICATION_ID;

String str="Hai";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    final Notification notifyDetails = new Notification(R.drawable.android,"New Alert, Click Me!",System.currentTimeMillis());


    Button start = (Button)findViewById(R.id.notifyButton);
    Button cancel = (Button)findViewById(R.id.cancelButton);



        start.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {


            Context context = getApplicationContext();
            CharSequence contentTitle = "Notification Details...";
            CharSequence contentText = "Browse Android Official Site by clicking me"; …

我有一个相当简单的应用程序,它接受用户的输入,然后将其设置为通知.用户可以创建他/她喜欢的任意数量的通知.我希望用户单击该通知并进入一个名为的新活动ResultActivity.ResultActivity反过来putExtras从通知意图中读取并将其显示给用户.下面的代码允许我做几乎我想要的一切,除非按下通知,我收到putExtra最后创建的通知.

Intent notificationIntent = new Intent(ctx, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(ctx, i,notificationIntent,PendingIntent.FLAG_CANCEL_CURRENT);

NotificationManager nm = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

Resources res = ctx.getResources();
NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx);
builder.setContentIntent(contentIntent)
    .setSmallIcon(R.drawable.ic_launcher)
    .setLargeIcon(BitmapFactory.decodeResource(res,R.drawable.ic_launcher))
    .setTicker("Remember to " + text.getText())
    .setWhen(System.currentTimeMillis()).setAutoCancel(true)
    .setContentTitle(text.getText());

// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, ResultActivity.class);
String pass = text.getText().toString();

resultIntent.putExtra("title", pass);
resultIntent.putExtra("uid", i);

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the …

我开发了一个应用程序,用户可以在其中创建事件并为该事件设置通知.所以我想添加多个通知.我使用以下代码.

final Notification notifyDetails = new Notification(R.drawable.icon, "Myapp",calendar.getTimeInMillis());
Context context = getApplicationContext();
Intent notifyIntent = new Intent(context, ViewDoughnut.class);
PendingIntent pendingIntent = PendingIntent.getActivity(ViewCal.this, 0, notifyIntent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
notifyDetails.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);
notifyDetails.flags = Notification.FLAG_ONGOING_EVENT;
mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);

当我使用上面的代码添加事件并创建通知时,它工作正常.但是如果我添加另一个事件,没有创建新通知,旧的通知就会更新.我想再添加一个通知.怎么做？此外,如果用户删除与其对应的事件,我想删除任何特定通知.怎么可能？

public static void showNotification(Context ctx, int value1, String title, String message, int value2){

    NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(ctx, ActivityMain.class);
    int not_id = Utils.randInt(1111, 9999);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
    notificationIntent.putExtra("key_1", value1);
    notificationIntent.putExtra("key_2", value2);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(ctx.getApplicationContext());
    stackBuilder.addNextIntent(notificationIntent);
    PendingIntent notifPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

    notificationManager.notify(not_id, createNotification(ctx, notifPendingIntent, title, message));
}

这是我发送和显示notification. 我从服务发送这个。正如你所看到的，我发送了 2 个额外的值，目的是（key_1和key_2）；当我单击通知时，我应该打开活动并查看按键的value1和。value2

问题是：如果在我打开其中任何一个之前收到另一个通知，value1并且value2该通知被覆盖。例如：

• 第一个通知发送foo并且bar

  • 第二个通知发送faz并且baz

  • 第三次通知发送fubar和fobaz …
