android notification 的总结分析（android notificationmanager）

分类

notification有以下几种:

　　1>普通notification

　　　　1.内容标题

　　　　2.大图标

　　　　3.内容

　　　　4.内容附加信息

　　　　5.小图标

　　　　6.时间

　　2>大布局Notification

图1

　　大布局notification是在android4.1以后才增加的，大布局notification与小布局notification只在‘7'部分有区别，其它部分都一致。大布局notification只有在所有notification的最上　　面时才会显示大布局，其它情况下显示小布局。你也可以用手指将其扩展为大布局(前提是它是大布局)。如下图：

图2

　　　　大布局notification有三种类型：如图1为NotificationCompat.InBoxStyle 类型。图2左部为NotificationCompat.BigTextStyle。图2右部为：NotificationCompat.BigPictureStyle

　　3>自定义布局notification

　　　　除了系统提供的notification，我们也可以自定义notification。如下图所示的一个音乐播放器控制notification:

图3

如何创建notification

　　　　1>实例化一个NotificationCompat.Builder对象;如builder

　　　　 2>调用builder的相关方法对notification进行上面提到的各种设置

　　　　3>调用builder.build()方法此方法返回一个notification对象。

　　　　 4>实例化一个notificationmanager对象；如：manager

　　　　 5>调用manager的notify方法。

　　注：

　　一个notification不必对上面所有的选项都进行设置，但有3项是必须的：

　　小图标,set by setSmallIcon()

　内容标题,set by setContentTitle()

　内容,set by setContentText()

0>初始化部分代码

复制代码代码如下:

View Code
public class MainActivity extends Activity implements OnClickListener {

     private static final int NOTIFICATION_ID_1 = 0;
     private static final int NOTIFICATION_ID_2 = 1;
     private static final int NOTIFICATION_ID_3 = 2;
     private static final int NOTIFICATION_ID_4 = 3;
     private static final int NOTIFICATION_ID_5 = 4;
     private static final int NOTIFICATION_ID_6 = 5;
     private static final int NOTIFICATION_ID_7 = 6;
     private static final int NOTIFICATION_ID_8 = 7;

     private static int messageNum = 0;
     private Context context = this;
     private notificationmanager manager;
     private Bitmap icon;
     private static final int[] btns = new int[] { R.id.btn1,R.id.btn2,
             R.id.btn3,R.id.btn4,R.id.btn5,R.id.btn6,R.id.btn7,R.id.btn8,
             R.id.btn9 };

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         init();
     }

     private void init() {
         // 获取通知服务
         manager = (notificationmanager) getSystemService(Context.NOTIFICATION_SERVICE);
         // 注册监听器
         for (int btn : btns) {
             findViewById(btn).setonClickListener(this);
         }

         icon = BitmapFactory.decodeResource(getResources(),
                 R.drawable.ic_launcher);
     }

     @Override
     public void onClick(View v) {
         switch (v.getId()) {
         case R.id.btn1:
             shownormal();
             break;
         case R.id.btn2:
             showBigView_Text();
             break;
         case R.id.btn3:
             showBigView_Pic();
             break;
         case R.id.btn4:
             showBigView_InBox();
             break;
         case R.id.btn5:
             showCustomView();
             break;
         case R.id.btn6:
             backApp();
             break;
         case R.id.btn7:
             backScreen();
             break;
         case R.id.btn8:
             showProgressBar();
             break;
         case R.id.btn9:
             dismiss();
             break;
         default:
             Toast.makeText(context,"error",Toast.LENGTH_SHORT).show();
             break;
         }
     }

     private void dismiss() {
         manager.cancelAll();
     }

1>普通notification

复制代码代码如下:

View Code
     private void shownormal() {

         Notification notification = new NotificationCompat.Builder(context)
                 .setLargeIcon(icon).setSmallIcon(R.drawable.ic_launcher)
                 .setTicker("shownormal").setContentInfo("contentInfo")
                 .setContentTitle("ContentTitle").setContentText("ContentText")
                 .setNumber(++messageNum)
                 .setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL)
                 .build();
         manager.notify(NOTIFICATION_ID_1,notification);
     }

2>大布局Text类型notification

复制代码代码如下:

View Code
private void showBigView_Text() {
         NotificationCompat.BigTextStyle textStyle = new BigTextStyle();
         textStyle
                 .setBigContentTitle("BigContentTitle")
                 .setSummaryText("SummaryText")
                 .bigText(
                         "I am Big Texttttttttttttttttttttttttttttttttttttttttttt!!!!!!!!!!!!!!!!!!!......");
         Notification notification = new NotificationCompat.Builder(context)
                 .setLargeIcon(icon).setSmallIcon(R.drawable.ic_launcher)
                 .setTicker("showBigView_Text").setContentInfo("contentInfo")
                 .setContentTitle("ContentTitle").setContentText("ContentText")
                 .setStyle(textStyle)
                 .setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL)
                 .build();
         manager.notify(NOTIFICATION_ID_2,notification);
     }

// Key for the string that''s delivered in the action''s intent. private static final String KEY_TEXT_REPLY = "key_text_reply"; String replyLabel = getResources().getString(R.string.reply_label); RemoteInput remoteInput = new RemoteInput.Builder(KEY_TEXT_REPLY) .setLabel(replyLabel) .build();

// Create the reply action and add the remote input. Notification.Action action = new Notification.Action.Builder( R.drawable.ic_reply_icon, getString(R.string.label), replyPendingIntent) .addRemoteInput(remoteInput) .build();

// Build the notification and add the action. Notification newMessageNotification = new Notification.Builder(mContext) .setSmallIcon(R.drawable.ic_message) .setContentTitle(getString(R.string.title)) .setContentText(getString(R.string.content)) .addAction(action)) .build(); // Issue the notification. NotificationManager notificationManager = NotificationManager.from(mContext); notificationManager.notify(notificationId, newMessageNotification);

// Obtain the intent that started this activity by calling // Activity.getIntent() and pass it into this method to get the associated string. private CharSequence getMessageText(Intent intent) { Bundle remoteInput = RemoteInput.getResultsFromIntent(intent); if(remoteInput != null) { return remoteInput.getCharSequence(KEY_TEXT_REPLY); } return null; }

// Build a new notification, which informs the user that the system // handled their interaction with the previous notification. Notification repliedNotification = new Notification.Builder(context) .setSmallIcon(R.drawable.ic_message) .setContentText(getString(R.string.replied)) .build(); // Issue the new notification. NotificationManager notificationManager = NotificationManager.from(context); notificationManager.notify(notificationId, repliedNotification);
