Notification 版次差異

早期 API8 對 Notification 並未完全封裝內部變數, 因API版本不段演變, 舊有使用方式將被取消, 因此就需要改變該類的使用方式.
要帶入到Notification的資料(非重點)

int icon = R.drawable.ic_stat_gcm;
long when = System.currentTimeMillis();
String contentTitle = context.getString(R.string.app_name);
String message = "訊息內容";
//
Intent notificationIntent = new Intent(context, MessageShow.class);//MessageShow顯示訊息的activity
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationIntent.putExtra(CommonUtilities.EXTRA_MESSAGE, message);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

►API-10 以前的用法

Notification notification = new Notification(icon, message, when);
notification.setLatestEventInfo(this, contentTitle, message, contentIntent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);

►相容 API-10 以前的用法, 主要是改用 android-support-v4.jar 來上下版本相容

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(icon);
builder.setTicker("訊息通知:Ticker");//訊息提醒時顯示的提示文字
builder.setWhen(when);
builder.setContentIntent(contentIntent);
builder.setContentTitle(contentTitle);//"通知標題"
builder.setContentText(message);//"通知摘要"
builder.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE);
builder.setAutoCancel(true);
notificationManager.notify(0, builder.build());//發出通知, 標準樣式

►API-11 後的用法 (Notification已重新封裝)

Notification notification = new Notification.Builder(this)
        .setSmallIcon(icon)
        .setWhen(when)
        .setContentTitle(contentTitle)
        .setContentText(message)
        .setContentIntent(contentIntent)
        .getNotification();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(R.string.app_name, notification);

►不同呈現樣式
訊息追加方式

builder.addAction(icon, "訊息1", contentIntent);
builder.addAction(icon, "訊息2", contentIntent);

大文字標題樣式

NotificationCompat.BigTextStyle bigTextStyle = new NotificationCompat.BigTextStyle(builder);
bigTextStyle.bigText("BigText");
bigTextStyle.setBigContentTitle("BigContentTitle");
bigTextStyle.setSummaryText("SummaryText");
notificationManager.notify(0, bigTextStyle.build());

多列清單樣式

NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle(builder);
inboxStyle.setBigContentTitle("BigContentTitle");
inboxStyle.setSummaryText("SummaryText");
for (int i = 0; i < 10; i++) {
    inboxStyle.addLine("Line" + (i + 1));
}
notificationManager.notify(0, inboxStyle.build());

圖片樣式

NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle(builder);
bigPictureStyle.bigPicture(bigPicture);
bigPictureStyle.setBigContentTitle("BigContentTitle");
bigPictureStyle.setSummaryText("SummaryText");
