AndroidAndroid不同版本下Notification创建方法 _notification

【AndroidAndroid不同版本下Notification创建方法】壮心未与年俱老，死去犹能作鬼雄。这篇文章主要讲述AndroidAndroid不同版本下Notification创建方法相关的知识，希望能为你提供帮助。
使用 new Notification(int icon, CharSequence tickerText, long when)构造函数时，Eclipse却提示：" The constructor Notification(int, CharSequence, long) is deprecated "

/** * Constructs a Notification object with the information needed to * have a status bar icon without the standard expanded view. * * @param icon The resource id of the icon to put in the status bar. * @param tickerText The text that flows by in the status bar when the notification first * activates. * @param when The time to show in the time field. In the System.currentTimeMillis * timebase. * * @deprecated Use {@link Builder} instead. */ @Deprecated public Notification(int icon, CharSequence tickerText, long when) { this.icon = icon; this.tickerText = tickerText; this.when = when; }

在不同的版本下Notification使用有一些不同，涉及到Builder的使用。现在总结如下，希望对以后使用的程序员有所帮助。

低于API Level 11版本，也就是android 2.3.3以下的系统中，setLatestEventInfo()函数是唯一的实现方法。前面的有关属性设置这里就不再提了，网上资料很多。

Intentintent = new Intent(this,MainActivity); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT); notification.setLatestEventInfo(context, title, message, pendingIntent); manager.notify(id, notification);

高于API Level 11，低于API Level 16 (Android 4.1.2)版本的系统中，可使用Notification.Builder来构造函数。但要使用getNotification()来使notification实现。此时，前面版本在notification中设置的Flags，icon等属性都已经无效，要在builder里面设置。

Notification.Builder builder = new Notification.Builder(context) .setAutoCancel(true) .setContentTitle("title") .setContentText("describe") .setContentIntent(pendingIntent) .setSmallIcon(R.drawable.ic_launcher) .setWhen(System.currentTimeMillis()) .setOngoing(true); notification=builder.getNotification();

高于API Level 16的版本，就可以用Builder和build()函数来配套的方便使用notification了。

Notification notification = new Notification.Builder(context) .setAutoCancel(true) .setContentTitle("title") .setContentText("describe") .setContentIntent(pendingIntent) .setSmallIcon(R.drawable.ic_launcher) .setWhen(System.currentTimeMillis()) .build();

【注意点】：
在构造notification的时候有很多种写法，但是要注意，用
Notification notification = new Notification();
这种构建方法的时候，一定要加上notification.icon这个设置，不然，程序虽然不会报错，但是会没有效果。
问题：
使用了Notification下的setLatestEventInfo()方法时，Eclipse却提示：“ The method setLatestEventInfo(Context, String, String, PendingIntent) is undefined for the type Notification”！

/** * Sets the {@link #contentView} field to be a view with the standard "Latest Event" * layout. * * < p> Uses the {@link #icon} and {@link #when} fields to set the icon and time fields * in the view.< /p> * @param context The context for your application / activity. * @param contentTitle The title that goes in the expanded entry. * @param contentText The text that goes in the expanded entry. * @param contentIntent The intent to launch when the user clicks the expanded notification. * If this is an activity, it must include the * {@link android.content.Intent#FLAG_ACTIVITY_NEW_TASK} flag, which requires * that you take care of task management as described in the * < a href="https://www.songbingjia.com/android/{@docRoot}guide/topics/fundamentals/tasks-and-back-stack.html"> Tasks and Back * Stack< /a> document. * * @deprecated Use {@link Builder} instead. * @removed */ @Deprecatedpublic void setLatestEventInfo(Context context, CharSequence contentTitle, CharSequence contentText, PendingIntent contentIntent) { Notification.Builder builder = new Notification.Builder(context); // First, ensure that key pieces of information that may have been set directly // are preserved builder.setWhen(this.when); builder.setSmallIcon(this.icon); builder.setPriority(this.priority); builder.setTicker(this.tickerText); builder.setNumber(this.number); builder.setColor(this.color); builder.mFlags = this.flags; builder.setSound(this.sound, this.audiostreamType); builder.setDefaults(this.defaults); builder.setVibrate(this.vibrate); builder.setDeleteIntent(this.deleteIntent); // now apply the latestEventInfo fields if (contentTitle != null) { builder.setContentTitle(contentTitle); } if (contentText != null) { builder.setContentText(contentText); } builder.setContentIntent(contentIntent); builder.buildInto(this); }

setLatestEventInfo方法已被removed。
