步骤：

1、新建好点击后跳转的类和布局（不需要跳转可跳过此步骤）

2、注册（养成良好习惯，每个活动都需要注册）

3、设置 NotificationManager获取哪个服务

4、设置Notification.Builder（通知栏各属性）

5、设置“意图”

6、创建Notification对象并获得Notification.Builder对象的属性

7、通过NotificationManager对象的.notify显示通知栏
代码如下：

package com.example.administrator.notification;
 
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
 
/**
 * Created by Administrator on 2016/12/13.
 */
 
public class NotificationIntent extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notification_layout);
 
    }
}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
 
    <TextView
        android:id="@+id/text"
        android:text="this is a notification Intent"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
 
</LinearLayout>

2、注册

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.administrator.notification">
 
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
 
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
 
        <activity android:name=".NotificationIntent"></activity>
    </application>
 
</manifest>

3、Notification实现

package com.example.administrator.notification;
 
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
 
 
public class MainActivity extends AppCompatActivity {
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        Button button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //设置获取哪个服务
                NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                Notification.Builder builder = new Notification.Builder(MainActivity.this);
 
                builder.setSmallIcon(R.mipmap.ic_launcher);        //设置图标
                builder.setContentTitle("标题");                    //设置标题
                builder.setContentText("这是内容，点击我可以跳转");                 //消息内容
                builder.setWhen(System.currentTimeMillis());         //发送时间
                builder.setDefaults(Notification.DEFAULT_ALL);      //设置默认的提示音，振动方式，灯光
                builder.setAutoCancel(true);                         //打开程序后图标消失
 
                //跳转活动
                Intent intent =new Intent (MainActivity.this,NotificationIntent.class);
                PendingIntent pi = PendingIntent.getActivities(MainActivity.this, 0, new Intent[]{intent}, PendingIntent.FLAG_CANCEL_CURRENT);
                builder.setContentIntent(pi);
                //创建通知栏对象，显示通知信息
                Notification notification = builder.build();
                manager.notify(1, notification);
            }
        });
    }
}

还可以写成：

                Intent intent = new Intent(this, NotificationActivity.class);
                PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
 
                NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                Notification notification = new NotificationCompat.Builder(this)
                        .setSmallIcon(R.mipmap.ic_launcher)        //设置图标
                        .setContentTitle("标题")                    //设置标题
                        .setContentText("这是内容，点击我可以跳转")                 //消息内容
                        .setWhen(System.currentTimeMillis())         //发送时间
                        .setDefaults(Notification.DEFAULT_ALL)      //设置默认的提示音，振动方式，灯光
                        .setAutoCancel(true)                         //打开程序后图标消失
                        .setContentIntent(pendingIntent)              //设置点击响应
                    //显示所有内容
//                        .setStyle(new NotificationCompat.BigTextStyle().bigText("Hello world Hello world Hello world Hello world " +
//                                "Hello world Hello world Hello world "))
                    //显示图片
//                        .setStyle(new NotificationCompat.BigPictureStyle().bigPicture(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher)))
                    .build();
                manager.notify(1, notification);

以上两种返回会直接退出程序，但是实际开发中我们想要其返回到我们指定的主界面，所以可以参考下面方法

   <activity
            android:name=".NotificationActivity"
            android:parentActivityName=".MainActivity">

                Intent intent = new Intent(this, NotificationActivity.class);
 
                //设置TaskStackBuilder
                TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
                stackBuilder.addParentStack(NotificationActivity.class);
                stackBuilder.addNextIntent(intent);
 
                PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
 
                NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                Notification notification = new NotificationCompat.Builder(this)
                        .setSmallIcon(R.mipmap.ic_launcher)        //设置图标
                        .setContentTitle("标题")                    //设置标题
                        .setContentText("这是内容，点击我可以跳转")                 //消息内容
                        .setWhen(System.currentTimeMillis())         //发送时间
                        .setDefaults(Notification.DEFAULT_ALL)      //设置默认的提示音，振动方式，灯光
                        .setAutoCancel(true)                         //打开程序后图标消失
                        .setContentIntent(pendingIntent)              //设置点击响应
                        .build();
                manager.notify(1, notification)

Kotlin代码如下：

package com.leixiansheng.kotlintest
 
import android.app.Notification
import android.app.NotificationManager
import android.app.PendingIntent
import android.app.TaskStackBuilder
import android.content.Context
import android.content.Intent
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import android.support.v4.app.NotificationCompat
import kotlinx.android.synthetic.main.activity_main.*
 
class MainActivity : AppCompatActivity() {
 
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
 
        btn.setOnClickListener {
            notification()
            finish()
        }
    }
 
    fun notification() {
        val intent = Intent(this,NotificationActivity::class.java)
        val manager: NotificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
 
        val stackBuilder = TaskStackBuilder.create(this)
        stackBuilder.addParentStack(NotificationActivity::class.java)
        stackBuilder.addNextIntent(intent)
 
        val pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT)
 
        val notification = NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("标题")
                .setContentText("这是内容，点击我可以跳转")
                .setAutoCancel(true)
                .setDefaults(Notification.DEFAULT_ALL)
                .setWhen(System.currentTimeMillis())
                .setContentIntent(pendingIntent)
                .build()
 
        manager.notify(1,notification)
    }
}
