今天使用4.0.3使用
Notification notification2 = new Notification(R.drawable.advise2,
"通知测试",
System.currentTimeMillis()); notification2.setLatestEventInfo(getActivity(), "testTitle", "testContent", null);
结果androidstudio报错,setLatestEventInfo该方法找不到,经过查证官方在API Level 11中,该函数已经被替代,不推荐使用了。所以在4.0.3平台也就是API Level 15中,使用Notification的setLatestEventInfo()函数时,显示setLatestEventInfo()效果。建议使用Notification.Builder来创建 notification 实例
Notification.Builder builder1 = new Notification.Builder(MainActivity.this); builder1.setSmallIcon(R.drawable.advise2); //设置图标 builder1.setTicker("显示第二个通知"); builder1.setContentTitle("通知"); //设置标题 builder1.setContentText("点击查看详细内容"); //消息内容 builder1.setWhen(System.currentTimeMillis()); //发送时间 builder1.setDefaults(Notification.DEFAULT_ALL); //设置默认的提示音,振动方式,灯光 builder1.setAutoCancel(true);//打开程序后图标消失 Intent intent =new Intent (MainActivity.this,Center.class); PendingIntent pendingIntent =PendingIntent.getActivity(MainActivity.this, 0, intent, 0); builder1.setContentIntent(pendingIntent); Notification notification1 = builder1.build(); notificationManager.notify(124, notification1); // 通过通知管理器发送通知
如果该通知只是起到 “通知”的作用,不希望用户点击后有相应的跳转,那么,intent,pendingIntent这几行代码可以不写
Notification.Builder builder = new Notification.Builder(MainActivity.this); builder.setSmallIcon(R.drawable.advise); builder.setTicker("显示第一个通知"); builder.setContentTitle("第一个通知"); builder.setContentText("每天进步一点点"); builder.setWhen(System.currentTimeMillis()); //发送时间 builder.setDefaults(Notification.DEFAULT_ALL); Notification notification = builder.build(); notificationManager.notify(123, notification);
第一个具有点击提示有跳转功能,后面一个没有跳转功能,只是提示作用
以下借鉴其他博主的总结:
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。
Intent intent = 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。
Example:Notification的使用案例:
public class MainActivity extends Activity { private Button bt1; private NotificationManager notificationManager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_main); notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); setViews(); setlisteners(); } private void setlisteners() { bt1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { // 发送通知 Notification.Builder builder = new Notification.Builder(MainActivity.this); builder.setSmallIcon(R.mipmap.ic_launcher); builder.setTicker("this is ticker text"); // 通知的ticker内容,当通知刚创建的时候,它会在系统的状态栏一闪而过 builder.setContentTitle("this is title"); // 通知的标题 builder.setContentText("this is content"); // 通知内容 builder.setWhen(System.currentTimeMillis()); // 通知被创建的时间,以毫秒为单位 builder.setDefaults(Notification.DEFAULT_ALL); // 通知到来的时候,手机会发出振动、播放音乐、led灯亮的提示,具体是什么的提示,由手机的设置决定 Intent intent = new Intent(MainActivity.this,NotificationActivity.class); PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this,0,intent,PendingIntent.FLAG_CANCEL_CURRENT); builder.setContentIntent(pendingIntent); // 响应通知的点击事件 Notification notification = builder.getNotification(); notificationManager.notify(1, notification); } }); } private void setViews() { bt1 = (Button)findViewById(R.id.bt1); } }
NotificationActivity 通知的点击事件的响应活动:
public class NotificationActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_notification); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.cancel(1); // // 取消通知 参数:为创建通知的的通知id } }
