notificationCompat的使用

private void showNotification() {

    build.setSmallIcon(R.mipmap.ic_launcher);
    build.setTicker("这是通知");
    build.setContentTitle("这是标题");
    //设置优先级
    build.setPriority(NotificationCompat.PRIORITY_MIN);
    build.setContentText("这是内容");
    build.setContentIntent(getPendingIntent("普通文字", 0));

    //大图模式
    NotificationCompat.BigPictureStyle style = new NotificationCompat.BigPictureStyle();
    style.bigPicture(BitmapFactory.decodeResource(getResources(),
            R.mipmap.example_big_picture));
    style.setBigContentTitle("这是大标题");
    style.setSummaryText("这是大内容");
    build.setStyle(style).setDeleteIntent(getPendingIntent("删除", 3));

    //底部action
    build.addAction(R.mipmap.ic_launcher, "action1", getPendingIntent("action1", 1)).addAction(R.mipmap.ic_launcher, "action2", getPendingIntent("action2", 2));

    //多文字模式
//        NotificationCompat.BigTextStyle style = new NotificationCompat.BigTextStyle();
//        style.bigText("瑞典学院常任秘书长萨拉·丹尼尔斯宣布白俄罗斯作家斯维特拉娜·阿列克谢耶维奇（Svetlana Aleksijevitj ）获得2015年诺贝尔文学奖。\n" +
//                "颁奖词：她的复调作品是对我们时代的磨难与勇气的纪念。\n");
//        style.setBigContentTitle("这是大标题");
