notification几种点击事件

notification ：以另一种UI界面形式展示出来，点击时可以对其应用做处理。

其常用的一些基本属性：setSmallIcon（）设置图标   、setContentTitle（）设置题目、setContentText（）设置内容、setAutoCancel（）设置点击后是否自动销毁、setTicker（）设置通知时的滚动文本

1、构造通知、跳转界面

// 构造通知界面NotificationCompat.Builder builder = new NotificationCompat.Builder(NotifyActivity.this);builder.setSmallIcon(R.drawable.ic_launcher).setContentTitle(getString(R.string.hello_world)).setContentText(getString(R.string.hint_text)).setAutoCancel(true) // 点击跳转后自动销毁.setTicker(getString(R.string.hello_world)); // 设置滚动文本// 通知行为（点击后能进入应用界面）Intent intent = new Intent(NotifyActivity.this,Marquee_Test.class);PendingIntent pendingIntent = PendingIntent.getActivity(NotifyActivity.this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);builder.setContentIntent(pendingIntent);// 发送通知NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);manager.notify(1, builder.build()); // id不变则只显示一个，若id变化则可以重复显示多个

2、导航功能，返回应用首页

此时若点击返回时则直接跳出应用，若想其不退出应用还应在manifest中注册其父类路径（尽量使用4.1以上版本的模拟器，以下容易出错。）

<activity android:name="com.example.ui.widget.Marquee_Test"               <!-- 记住应在跳转界面下注册其父类 -->
            android:parentActivityName="com.example.layout.LayoutAll">   <!-- 1、注册方式一支持4.1以上版本 -->

<meta-data android:name="android.support.PARENT_ACTIVITY"<!-- 2、注册方式二 -->

android:value="com.example.layout.LayoutAll"  /> 

        </activity>

此时只改变上方通知行为部分即可

<span style="white-space:pre"></span>Intent intent = new Intent(NotifyActivity.this,Marquee_Test.class);           //要跳转的界面TaskStackBuilder taskStackBuilder = TaskStackBuilder.create(NotifyActivity.this);taskStackBuilder.addParentStack(Marquee_Test.class);    //参数为跳转界面taskStackBuilder.addNextIntent(intent);PendingIntent pendingIntent = taskStackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);builder.setContentIntent(pendingIntent);

3、BigView 系统按钮监听事件

此时也只用改变上方通知行为部分即可

<span style="white-space:pre"></span>//播放部分

<span style="white-space:pre"></span>Intent playIntent = new Intent(NotifyActivity.this,PlayMusicService.class);playIntent.setAction("1");playIntent.putExtra("PATH","file://"+ Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC)+ "/wy.mp3");playIntent.putExtra("FLAG", 1);PendingIntent playPending = PendingIntent.getService(NotifyActivity.this, 0, playIntent,PendingIntent.FLAG_UPDATE_CURRENT);<span style="white-space:pre"></span>//暂停部分Intent pauseIntent = new Intent(NotifyActivity.this,PlayMusicService.class);pauseIntent.putExtra("PATH","file://"+ Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC)+ "/wy.mp3");         //将播放文件传递到服务端pauseIntent.setAction("2");   //此时必须设置action，不然不能播放，单个控件时可以不用设置，参数自定义pauseIntent.putExtra("FLAG", 2);         //判断播放、暂停标记PendingIntent pausePending = PendingIntent.getService(NotifyActivity.this, 0, pauseIntent,PendingIntent.FLAG_UPDATE_CURRENT);builder.addAction(R.drawable.bg_actionbar, "播放", playPending);   //系统添加按钮控件builder.addAction(R.drawable.bg_actionbar, "暂停", pausePending);

4、自定义通知界面

<span style="white-space:pre"></span>NotificationCompat.Builder builder = new NotificationCompat.Builder(NotifyActivity.this);builder.setSmallIcon(R.drawable.ic_launcher);  //此条件必须设置，不然不能显示builder.setTicker("开始播放音乐");RemoteViews view = new RemoteViews(getPackageName(), R.layout.notify_play_music_layout); //自定义布局builder.setContent(view);Intent playIntent = new Intent(NotifyActivity.this,PlayMusicService.class);    //启动服务playIntent.setAction("1");playIntent.putExtra("PATH","file://"+ Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC)+ "/wy.mp3");playIntent.putExtra("FLAG", 1);PendingIntent playPending = PendingIntent.getService(NotifyActivity.this, 0, playIntent,PendingIntent.FLAG_UPDATE_CURRENT);view.setOnClickPendingIntent(R.id.music_play_img, playPending);  //设置监听事件NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);manager.notify(4, builder.build());
