基于百度云推送的实时通信客户端实现（三）

昨天已经说到了聊天列表的实现，今天来说说聊天界面的实现

在聊天界面会有两种布局，一种是

用户发送的消息的布局

另外一种是

用户收到的消息的布局

所以在这个时候Adapter的布局就需要对应两种界面，代码很简单

 1 <?xml version="1.0" encoding="utf-8"?>

list_talk_he_item.xml

其实两个布局基本上是一样的，只是ImagineView的位置在左侧或者在右侧的区别，另外，在这里的背景图片使用的是.9.png的格式，为了能够有更好的拉伸效果，不至于在拉伸以后失真

在这里，同样需要创建一个类MessageEnity来存储消息的内容

 1 package com.demo.Adapter;
 2 
 3 public class MessageEnity {
 4 
 5     @SuppressWarnings("unused")
 6     private static final String TAG = MessageEnity.class.getSimpleName();
 7 
 8     private String fromUser;
 9 
10     private String time;
11 
12     private String context;
13 
14     private String toUser;
15 
16     private int LayoutID;
17 
18     public String getfromUser() {
19         return fromUser;
20     }
21 
22     public void setfroUser(String fromUser) {
23         this.fromUser = fromUser;
24     }
25 
26     public String gettomUser() {
27         return toUser;
28     }
29 
30     public void settoUser(String toUser) {
31         this.toUser = toUser;
32     }
33 
34     public String getTime() {
35         return time;
36     }
37 
38     public void setTime(String date) {
39         this.time = date;
40     }
41 
42     public String getItem() {
43         return context;
44     }
45 
46     public void setItem(String text) {
47         this.context = text;
48     }
49 
50     public int getLayoutID() {
51         return LayoutID;
52     }
53 
54     public void setLayoutID(int LayoutID) {
55         this.LayoutID = LayoutID;
56     }
57 
58     public MessageEnity() {
59     }
60 
61     public MessageEnity(String fromUser, String toUser, String date,
62             String text, int LayoutID) {
63         this.fromUser = fromUser;
64         this.toUser = toUser;
65         this.time = date;
66         this.context = text;
67         this.LayoutID = LayoutID;
68     }
69 
70     public MessageEnity(String message,String toUser, String date, int LayoutID) {
71         String[] messages = message.split("@#@");
72         this.fromUser = messages[0];
73         this.context = messages[1];
74         this.toUser = toUser;
75         this.time = date;
76         this.LayoutID = LayoutID;
77     }
78 }

MessageEnity

在这里的Adapter的代码

  1 package com.demo.Adapter;

 24 
 25     // 构造函数

 29     }
 30

 37     }
 38 
 39     @Override
 40     public int getCount() {

 44 
 45     @Override

 49     }
 50

 56 
 57     public int getItemViewType(int position) {
 58         return position;
 59     }
 60 
 61     @Override

 63         // TODO Auto-generated method stub
 64         MessageEnity entity = coll.get(positon);
 65         int itemLayout = entity.getLayoutID();
 66 
 67         LinearLayout layout = new LinearLayout(context);
 68         LayoutInflater inflater = (LayoutInflater) context
 69                 .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 70         inflater.inflate(itemLayout, layout, true);
 71 
 72         TextView tvName = (TextView) layout.findViewById(R.id.person_name);
 73         tvName.setText(entity.getfromUser());
 74 
 75         TextView tvData = (TextView) layout.findViewById(R.id.time_say);
 76         tvData.setText(entity.getTime());
 77 
 78         TextView tvItem = (TextView) layout.findViewById(R.id.item_say);
 79         tvItem.setText(entity.getItem());
 80 
 81         return layout;
 82     }
 83 
 84     public int getViewTypeCount() {
 85         return coll.size();
 86     }
 87 
 88     public boolean hasStableIds() {
 89         return false;
 90     }
 91 
 92     public boolean isEmpty() {
 93         return false;
 94     }
 95 
 96     public void registerDataSetObserver(DataSetObserver observer) {
 97     }
 98 
 99     public void unregisterDataSetObserver(DataSetObserver observer) {
100     }
101 
102 }

NewAdapterView

TalkActivity

在这里主要还是监听各个状态，表示当前活动Activity的状态

另外还有最重要的东西了，在后台监听推送消息的service

PushMessageReceiver

这个方法是百度官方实现好的，在这里只需要更具自己的需要来进行修改就好，在我的demo中使用的是百度云推送中的消息的方法，它还提供了通知的富媒体的方法，大家可以根据自己的需要选用

Mainfest.xml

如果照着写到这里，会发现，没有动态更新，只能每次重新加载，这个问题困扰了我好几天，在这里我才用了使用广播的方法来处理，在service中接收到消息之后，发送广播通过定义不同的action来决定把广播发送给就拿一个Activity是否使用状态栏通知

我在PushMessageReceiver添加了如下的代码

 1 Intent intent1 = new Intent();
 2             Intent intent2 = new Intent();
 3             Intent intent3 = new Intent();
 4             intent1.setAction("android.myservice");
 5             intent2.setAction("com.talkmessage");
 6             intent3.setAction("com.newmessage");
 7             if (sp.getString("SSP", null).equals("0")) {
 8                 System.out.println("TAG!");
 9                 // context.sendBroadcast(intent1);
10                 showNotification();
11             } else if (sp.getString("SSP", null).equals("1")) {
12                 System.out.println("TAG@");
13                 context.sendBroadcast(intent1);
14             } else if (sp.getString("SSP", null).equals(entity.getfromUser())) {
15                 System.out.println("TAG#");
16                 context.sendBroadcast(intent2);
17             } else {
18                 System.out.println("TAG$");
19                 // context.sendBroadcast(intent3);
20                 showNotification();
21             }

 1 private void showNotification() {
 2 
 3         NotificationManager notificationManager = (NotificationManager) context
 4                 .getSystemService(android.content.Context.NOTIFICATION_SERVICE);
 5         Notification notification = new Notification(R.drawable.ic_launcher,
 6                 "来新消息了", System.currentTimeMillis());
 7         notification.flags = Notification.FLAG_AUTO_CANCEL;
 8         notification.defaults |= Notification.DEFAULT_VIBRATE;
 9         notification.defaults |= Notification.DEFAULT_LIGHTS;
10         long[] vibrate = { 0, 100, 200, 300 };
11         notification.vibrate = vibrate;
12         PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
13                 new Intent(context, PushDemoActivity.class), 0);
14         notification.setLatestEventInfo(context, "您有新消息", null, contentIntent);
15         notificationManager.notify(NOTIFICATION_ID, notification);
16     }

同时，在两个ACtivity中注册了BroadcastReceiver、

 1 public static class MyReceiver extends BroadcastReceiver {
 2 
 3         @Override
 4         public void onReceive(Context context, Intent intent) {
 5 
 6             String action = intent.getAction();
 7 
 8             if (action.equals("android.myservice")) {
 9                 talk = new ArrayList<TalkListInfo>();
10 
11                 talk = help.findList(userid);
12 
13                 if (talk != null) {
14                     for (TalkListInfo t : talk) {
15 
16                         map.put("name", t.getName());
17                         map.put("time", t.getDate());
18                         map.put("content", t.getItem());
19                     }
20                     adapter = new ListAdapter(context, talk);
21                     list.setAdapter(adapter);
22                 }
23             } else if (action.equals("com.newmessage")) {
24 
25             }
26         }
27 
28     }

同时，在activity的重新唤醒等各个状态中添加了重新构造Adapter是Demo能够真正做到实时更新
