一、在LV16以前的用法

public class MainActivity extends Activity { private NotificationManager notificationManager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); } public void test1(View v){ //Toast.makeText(this, "点击我了", Toast.LENGTH_LONG).show(); showNotification("来短信了", "5554", "I love you", R.drawable.ic_launcher, R.drawable.ic_launcher); } public void showNotification(String tickerText,String contentTitle,String contentText,int iconId,int notiId){ //2步创建一个Notification Notification notification = new Notification(); //设置通知 消息 图标 notification.icon=iconId; //设置发出消息的内容 这个指的是刚推送出的内容 notification.tickerText=tickerText; //设置发出通知的时间 notification.when=System.currentTimeMillis(); //设置显示通知时的默认的发声、振动、Light效果 notification.defaults = Notification.DEFAULT_VIBRATE;//振动 //Notification notification = new Notification(R.drawable.ic_launcher, "有新的消息", System.currentTimeMillis()); //3步:PendingIntent android系统负责维护 PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, getIntent(), 0); //4步:设置更加详细的信息 notification.setLatestEventInfo(this, contentTitle, contentText, pendingIntent); //5步:使用notificationManager对象的notify方法 显示Notification消息 需要制定 Notification的标识 notificationManager.notify(notiId, notification); } public void clearNoti(View v){ notificationManager.cancel(notiId);//清除具体的Notifaction notificationManager.cancelAll();//清除所有 } }

//设置Intent跳转 Intent intent = new Intent(this,OtherActivity.class); PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT); //利用Notification.Builder创建Notification Notification.Builder notification = new Notification.Builder(this); notification.setAutoCancel(true); notification.setSmallIcon(R.mipmap.ic_launcher); notification.setContentTitle("Hello World"); notification.setContentText("I am a ET"); notification.setContentIntent(pendingIntent); //创建Notification Notification notification1 = notification.build(); //获取Notification管理器 NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); //执行 manager.notify(0,notification1)
