Android自定义Notification布局的实现方法

ゝ一世哀愁。 2022-05-25 06:17 670阅读 0赞

1、自定义一个带按钮的Notification布局：layout\_notification；

2、创建Notification

RemoteViews views = new RemoteViews(getPackageName(),R.layout.layout_nitification);　　//自定义的布局视图
    
    //按钮点击事件：
    
    PendingIntent homeIntent = PengdingIntent.getBroadcast(this,1,new Intent("action"),PengdingIntent.FLAG_UPDATE_CURRENT);
    
    views.setOnClickPendingIntent(R.id.btn,homeIntent);　　　　//点击的id，点击事件
    
    //创建通知：
    
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext);
    
    mBuilder.setContent(views)　　　　//设置布局
    
    　　　　　.setOngoing(true)　　　　//设置是否常驻,true为常驻
    
    　　　　　.setSmallIcon(R.mipmap.ic_laucher)　　　　//设置小图标
    
    　　　　　.setTicker("通知来了")　　　　　　　　//设置提示
    
    　　　　　.setPriority(Notification.PRIORITY_MAX)　　//设置优先级
    
    　　　　　.setWhen(System.currentTimeMillis())　　　　//设置展示时间
    
    　　　　　.setContentIntent(PendingIntent.getBroadcast(this,2,new Intent("action.view"),PengingIntent.FLAG_UPDATE_CURRENT);　　　　//设置视图点击事件
    
    NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    
    mNotificationManager.notify(100,mBuilder.build())　　　　//显示通知： 当前notificationid，当前notification

3、创建NotificationBroadcast接收通知

public class NotificationBroadcast extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();　　　　//动作
            collapseStatusBar(context);　　　　　　　　//收起通知栏
            Intent i = new Intent(context,MainActivity.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);　　　　//必须添加，避免重复打开
            if (action.equals("com.xczl.smart.notification.home")){
                i.putExtra("flag","home");　　　　//传值
                context.startActivity(i);
            }
        }　
    
        public void collapseStatusBar(Context context) {
            try {
                Object statusBarManager = context.getSystemService("statusbar");
                Method collapse;
                if (Build.VERSION.SDK_INT <= 16) {
                    collapse = statusBarManager.getClass().getMethod("collapse");
                } else {
                    collapse = statusBarManager.getClass().getMethod("collapsePanels");
                }
                collapse.invoke(statusBarManager);
            } catch (Exception localException) {
                localException.printStackTrace();
            }
        }

4、配置清单

MainActivity：设置LanchMode为singleTask
    注册Broadcast：
    <receiver
        android:name="com.xczl.smart.broadcast.NotificationBroadcast"
        android:enabled="true">
        <intent-filter>
            <action android:name="action"/>
            <action android:name="action.view"/>
        </intent-filter>
    </receiver>
    配置通知栏伸缩权限：　　
    <uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>

5、MainActivity接收消息

//覆写 onNewIntent()
    @Override
    protected void onNewIntent(Intent intent) {
       String extra = intent.getStringExtra("flag");
       if (!TextUtils.isEmpty(extra)){
          if (extra.equals("home")){
             //接收到值的具体操作
          }
       }
    }

代码示例：

a、类GlobalDeclare

public class GlobalDeclare {
    
        //notification点击广播
        public final static String ACTION_NOTIFICATION_CLICK = "com.ACTION_NOTIFICATION_CLICK";
    
    }

b、类NotifyClickReceiver

/** * 全局广播 * Created by xl on 2018/5/9. */ public class NotifyClickReceiver extends BroadcastReceiver {
    
        private final static String TAG = NotifyClickReceiver.class.getSimpleName();
    
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if(GlobalDeclare.ACTION_NOTIFICATION_CLICK.equals(action)){
                MyLogger.i(TAG, "broadcast");
            }
        }
    }

c、清单文件声明

d、showNotification函数

public void showNotification(Context context, String title, String msg) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        builder.setAutoCancel(true);//点击后消失
        builder.setSmallIcon(R.mipmap.ic_launcher);//设置通知栏消息标题的头像
        builder.setDefaults(NotificationCompat.DEFAULT_ALL);//设置通知铃声，震动，闪光灯
        builder.setTicker(context.getText(R.string.app_name));
        builder.setContentTitle(title);
        builder.setContentText(msg);
        //Intent intent = new Intent();//只显示通知，无页面跳转
        Intent intent = new Intent(GlobalDeclare.ACTION_NOTIFICATION_CLICK);//将要跳转的界面
        //intent.setAction(GlobalDeclare.ACTION_NOTIFICATION_CLICK);
        //Intent intent = new Intent(context, NotifyClickReceiver.class);//将要跳转的界面
        //利用PendingIntent来包装我们的intent对象,使其延迟跳转
        int id = (int) (System.currentTimeMillis() / 1000);
        PendingIntent intentPend = PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_CANCEL_CURRENT);
        builder.setContentIntent(intentPend);
        NotificationManager manager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
        manager.notify(0, builder.build());
    }

完！！！
