這篇文章主要為大家詳細(xì)介紹了Notification消息通知，消息合并且顯示條數(shù)，自定義消息通知內(nèi)容布局，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

具體操作：自定義消息通知內(nèi)容布局；點(diǎn)擊界面中心的“點(diǎn)擊發(fā)送消息”TextView控件，模擬發(fā)送通知消息，通知欄接收消息，點(diǎn)擊幾次則發(fā)送幾次，點(diǎn)擊通知欄消息，跳轉(zhuǎn)到詳情界面。

1.activity_main.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:gravity="center"
  tools:context=".MainActivity">

  <TextView
    android:id="@+id/tv_show"
    android:text="點(diǎn)擊發(fā)送消息"
    android:textSize="24sp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

</LinearLayout>

2.layout_item.xml：

    android:layout_alignLeft="@+id/textView1"
    android:layout_below="@+id/textView1"
    android:layout_marginTop="15dp"
    android:text="TextView" />

  <TextView

    android:layout_height="wrap_content"
    android:text="New Text"
    android:id="@+id/name"
    android:textSize="18sp"

/**
 * 用于存儲(chǔ)消息數(shù)目
 * Created by admin on 2017/9/4.
 */

public class SingletonF{

  private int info_number=0;

  private static class SingletonHolder {
    /**
     * 單例對(duì)象實(shí)例
     */
    static final SingletonF INSTANCE = new SingletonF();
  }

  public static SingletonF getInstance() {
    return SingletonHolder.INSTANCE;
  }

  /**
  * private的構(gòu)造函數(shù)用于避免外界直接使用new來實(shí)例化對(duì)象
  */
  private SingletonF() {}

  public int getInfo_number() {
    return info_number;
  }

  public void setInfo_number(int info_number) {
    this.info_number = info_number;
  }

//  /**
//   * 若SingletonF implements Serializable則必須實(shí)現(xiàn)readResolve方法
//   * readResolve方法應(yīng)對(duì)單例對(duì)象被序列化時(shí)候

  public void onReceive(Context context, Intent intent) {
    this.context1 = context;
//   if (intent.getStringExtra("info").equals("廣播發(fā)送了")) {
//     Log.i("靜態(tài)廣播：", "廣播我已經(jīng)接受了");
//   }
    Message message = handler.obtainMessage();
    message.what = 0;
    handler.sendMessage(message);
  }

  private Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
      switch (msg.what) {
        case 0:
          singletonF = SingletonF.getInstance();
          int first = singletonF.getInfo_number();
          first++;
          Date nowTime = new Date(System.currentTimeMillis());
          SimpleDateFormat sdFormatter = new SimpleDateFormat("HH:mm");
          String retStrFormatNowDate = sdFormatter.format(nowTime);
          singletonF.setInfo_number( first);

          RemoteViews contentViews = new RemoteViews(context1.getPackageName(), R.layout.layout_item);
          // 通過控件的Id設(shè)置屬性
          contentViews.setImageViewResource(R.id.imageView1, R.mipmap.ic_launcher_round);
          contentViews.setTextViewText(R.id.textView1, "消息標(biāo)題");
          contentViews.setTextViewText(R.id.textView2, "消息內(nèi)容");
          contentViews.setTextViewText(R.id.textView3, " (" + first + "條新消息)");
          contentViews.setTextViewText(R.id.textView4, "" + retStrFormatNowDate);
          // 點(diǎn)擊通知欄跳轉(zhuǎn)的activity
          Intent intent = new Intent(context1, ActDetail.class);
          PendingIntent pendingIntent = PendingIntent.getActivity(context1, 0, intent,
              PendingIntent.FLAG_CANCEL_CURRENT);

          NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context1)
              .setSmallIcon(R.mipmap.ic_launcher_round).setTicker("new message");
          // 自動(dòng)管理通知欄消息
          mBuilder.setAutoCancel(true);
          mBuilder.setContentIntent(pendingIntent);
          /// 自定義布局
          mBuilder.setContent(contentViews);
          // 使用默認(rèn)提示音
          mBuilder.setDefaults(Notification.DEFAULT_ALL);
          NotificationManager mNotificationManager = (NotificationManager) context1
              .getSystemService(context1.NOTIFICATION_SERVICE);
          // notify(int id, Notification notification)若id為同一個(gè)值，則通知欄只會(huì)顯示一行，并不停更新此消息內(nèi)容
          // 若為類似UUID.randomUUID().hashCode()這樣不同的唯一標(biāo)識(shí)符，則有幾條消息通知欄就顯示幾行
          mNotificationManager.notify(1, mBuilder.build());

          break;
        default:
          break;
