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" 
android:parentActivityName="com.example.layout.LayoutAll">

 
  <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());
