notification 学习

 

使用步骤：

1）创建自定义视图

2）获取远程视图对象（注：Notification的contentView不能为空）

3）设置PendingIntent（来响应各种事件）

4）发起Notification

大体4步骤这里就不详细说了，下面就把DEMO中的列子拿出来说下 

 

 1 Activity 中的代码

 

 

/**
 * Notification的使用
 * @author root
 *
 */
public class NotificationActivity extends Activity {
    
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notification);
        
        Button btn1 = (Button) findViewById( R.id.btn1);
        btn1.setOnClickListener( new BtnListener());
        Button btnCostom2 = (Button) findViewById( R.id.btn_costom2);
        btnCostom2.setOnClickListener( new BtnListener());    
        
    }

    
    class BtnListener implements  OnClickListener{

		@Override
		public void onClick(View v) {
			Integer id = v.getId();
			switch ( id ) {
				case R.id.btn1:
					notifition1();
					break;
				case R.id.btn_costom2:
					showCustomizeNotification();
					break;
				default:
					break;
			}
		}
    }
    
    /**
     *  Android 默认的notification 
     */
    private void notifition1(){
    	
        Bitmap btm = BitmapFactory.decodeResource(getResources(),
                R.drawable.ic_launcher);
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
        		NotificationActivity.this).setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("new message title")
                .setContentText("[e-mail]内容的主体");
        mBuilder.setTicker("New message");//第一次提示消息的时候显示在通知栏上
        mBuilder.setNumber(12);
        mBuilder.setLargeIcon(btm);
        mBuilder.setAutoCancel(true);//自己维护通知的消失
        
        //构建一个Intent，点击通知栏，则跳转到 MainActivity上
        Intent resultIntent = new Intent(NotificationActivity.this,
        		MainActivity.class);
        //封装一个Intent
        PendingIntent resultPendingIntent = PendingIntent.getActivity(
        		NotificationActivity.this, 0, resultIntent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        // 设置通知主题的意图
        mBuilder.setContentIntent(resultPendingIntent);
        //获取通知管理器对象
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(0, mBuilder.build());	
    	
    }
    
    /**
     * 自定义 Notification的布局 
     */
    private   void  showCustomizeNotification(){
    	  CharSequence title = "i am new";  
          int icon = R.drawable.ic_launcher;  
          long when = System.currentTimeMillis();  
          Notification noti = new Notification(icon, title, when + 10000);  
          noti.flags = Notification.FLAG_INSISTENT;  
            
          // 1、创建一个自定义的消息布局 view.xml  
          // 2、在程序代码中使用RemoteViews的方法来定义image和text。然后把RemoteViews对象传到contentView字段  
          RemoteViews remoteView = new RemoteViews(this.getPackageName(),R.layout.notification_costom);  
          remoteView.setImageViewResource(R.id.image, R.drawable.ic_launcher);  
          remoteView.setTextViewText(R.id.text , "通知类型为：自定义View");  
          noti.contentView = remoteView;  
          // 3、为Notification的contentIntent字段定义一个Intent(注意，使用自定义View不需要setLatestEventInfo()方法)  
           
          //这儿点击后简单启动Settings模块  (Activity)
          PendingIntent contentIntent = PendingIntent.getActivity  
                           (NotificationActivity.this, 0,new Intent("android.settings.SETTINGS"), 0);  
          noti.contentIntent = contentIntent;  


          NotificationManager mnotiManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);  
          mnotiManager.notify(1, noti);  
          
    }
}

 2 Activity 对应的布局

  

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="通知1" />
    
    <Button
        android:id="@+id/btn_costom2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="通知2" />  

</LinearLayout>

 3 自定义的notification的布局 

  

<?xml version="1.0" encoding="utf-8"?>  
  
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:orientation="horizontal" android:layout_width="fill_parent"  
    android:layout_height="fill_parent">  
  
    <ImageView android:id="@+id/image" android:layout_width="wrap_content"  
        android:layout_height="fill_parent" />  
  
    <TextView android:id="@+id/text" android:layout_width="wrap_content"  
        android:layout_toRightOf="@+id/image"  
        android:layout_height="wrap_content" android:textColor="#000" />  

    <Button android:id="@+id/btn1" android:layout_width="wrap_content"  
        android:layout_toRightOf="@+id/image"  
        android:layout_height="wrap_content" android:textColor="#000" 
        android:text="点击跳转"/>  
              
    <ProgressBar android:id="@+id/progress_horizontal"  
        style="?android:attr/progressBarStyleHorizontal"   
        android:layout_below="@+id/text"  
        android:layout_toRightOf="@+id/image"  
        android:layout_width="fill_parent" android:layout_height="wrap_content"  
        android:max="100" android:progress="50" android:secondaryProgress="75" />  
  
  
</RelativeLayout>
