1、普通Notification和自定义布局的Notification：

(1)如果不是在activity显示通知，但有传context，则

 manager=(NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

package com.example.mynotification;import android.app.Activity;import android.app.Notification;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.RemoteViews;public class MainActivity extends Activity {    private Button button,button2;    //别忘了实例化NotificationManager，Notification.Builder     //二者通过Notification notification=builder.build();以及    //NotificationManager.notify(int id, Notification notification)    private NotificationManager manager;    Notification.Builder builder;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        button = (Button) findViewById(R.id.button1);        button2 = (Button) findViewById(R.id.button2);        //实例化NotificationManager        manager=(NotificationManager)getSystemService(NOTIFICATION_SERVICE);        //实例化Builder        builder=new Notification.Builder(MainActivity.this);        button.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                // TODO Auto-generated method stub                // Notification.Builde->Notification->NotificationManager                // 图标，标题，消息，PenddIngntent                Intent intent = new Intent(MainActivity.this,                        MainActivity.class);                PendingIntent pendingIntent = PendingIntent.getActivity(                        MainActivity.this, 0, intent, 0);                //点击通知跳转的pendingIntent                builder.setContentIntent(pendingIntent);                //通知的标题                builder.setContentTitle("标题");                //通知的正文文本                builder.setContentText("你好啊！");                //状态栏上的图标以及拉下之后左侧的图标，必不可少                builder.setSmallIcon(R.drawable.noticon);                //第一次产生提醒时会显示的文本                builder.setTicker("普通通知");                //设置消息提醒默认的设置                //默认震动；震动需要添加用户权限                //默认闪光                //默认铃声                builder.setDefaults(Notification.DEFAULT_ALL);                Notification notification=builder.build();                //设置使点击后通知消失                notification.flags=Notification.FLAG_AUTO_CANCEL;                // 1000为id数值，唯一标识                manager.notify(1, notification);            }        });        button2.setOnClickListener(new OnClickListener() {                        @Override            public void onClick(View v) {                // TODO Auto-generated method stub                Notification.Builder builder=new Notification.Builder(MainActivity.this);                RemoteViews remoteViews=new RemoteViews(getPackageName(),R.layout.mynoti);                remoteViews.setTextViewText(R.id.textView1, "自定义通知！");                Intent intent = new Intent(MainActivity.this,                        MainActivity.class);                PendingIntent pendingIntent = PendingIntent.getActivity(                        MainActivity.this, 0, intent, 0);                //指定Intent                builder.setContentIntent(pendingIntent);                //自定义布局                builder.setContent(remoteViews);                //设置图标必不可少                builder.setSmallIcon(R.drawable.noticon);                builder.setTicker("自定义通知");                Notification notification=builder.build();                manager.notify(5, notification);            }        });    }}

自定义的布局：mynoti.xml
