【Android】自定义状态栏通知

在项目开发中,我们有时候需要自定义状态栏通知的样式,以下就是自定义状态栏通知的一个案例代码,以此作为一个记录,有需要的童鞋也可以参考一下

1. 状态栏通知布局custom_notification.xml

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="64dp"
       android:background="@android:color/white">
   
       <ImageView
           android:id="@+id/image"
           android:layout_width="40dp"
           android:layout_height="40dp"
           android:layout_alignParents="true"
           android:layout_centerVertical="true"
           android:layout_marginLeft="10dp"
           android:layout_marginRight="10dp" />
   
       <RelativeLayout
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_centerVertical="true"
           android:layout_toRightOf="@id/image">
   
           <TextView
               android:id="@+id/title"
               style="@style/NotificationTitle"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:layout_alignParentTop="true" />
   
           <TextView
               android:id="@+id/text"
               style="@style/NotificationText"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:layout_below="@id/title"
               android:ellipsize="end"
               android:lines="2" />
   
           <TextView
               android:id="@+id/time"
               style="@style/NotificationText"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:layout_alignBottom="@id/title"
               android:layout_alignParentRight="true"
               android:layout_marginRight="5dip"
               android:layout_toLeftOf="@id/title" />
       </RelativeLayout>
   </RelativeLayout>
   

2. 这里面的style都是使用的继承系统的文字样式

   <!-- 自定义状态栏通知 -->
   <style name="NotificationText" parent="android:TextAppearance.StatusBar.EventContent">
       <item name="android:textColor">#bb000000</item>
       <item name="android:textSize">16px</item>
   </style>
   <style name="NotificationTitle" parent="android:TextAppearance.StatusBar.EventContent.Title">
       <item name="android:textColor">#bb000000</item>
   </style>
   

3. 创建自定义通知方法

   /**
    * 自定义通知
    */
   private void createCustomNotification(Context context, String tickerText,
                                         int drawable, String title, String content, int id,
                                         PendingIntent pendingIntent) {
       int icon = R.mipmap.ic_launcher;
       long when = System.currentTimeMillis();
       //必须要有这三个参数，不然出来的状态栏显示不全
       Notification notification = new Notification(icon, tickerText, when);
   
       RemoteViews contentView = new RemoteViews(this.getPackageName(), R.layout.custom_notification);
       contentView.setImageViewResource(R.id.image, drawable);
       contentView.setTextViewText(R.id.title, title);
       contentView.setTextViewText(R.id.text, content);
       // 设置日期格式
       SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
       String time = dateFormat.format(new Date());
       contentView.setTextViewText(R.id.time, time.substring((time.length() - 8), (time.length() - 3)));
   
       notification.contentView = contentView;
       notification.contentIntent = pendingIntent;
       notification.flags |= Notification.FLAG_AUTO_CANCEL;
       notification.defaults = Notification.DEFAULT_SOUND;
       NotificationManager mNotificationManager = (NotificationManager) context
               .getSystemService(Context.NOTIFICATION_SERVICE);
       mNotificationManager.notify(id, notification);
   }
