通常我们在接收消息的时候会有声音和震动的提示,因此我也加了代码达到这样的效果,这就要用到EventBus了,当然这里我也用到了自定义的广播,所以首先在Mainfests文件中加入以下代码:
<receiver
android:name=".MylocalMessage"
android:process=":bmobpush" >
<intent-filter>
<!-- 接收自定义广播的action -->
<action android:name="cn.edu.sau.action.MESSAGE" />
</intent-filter>
</receiver>
然后再写一个MessageEvent的Bean类对事件进行封装(这里只用到一个String类型的变量):
public class MessageEvent {
public final String message;
public MessageEvent(String message) {
this.message = message;
}
}
接下来我们在ImMessageHandler中接收到消息,并调用EventBus的post方法发送事件:
public class ImMessageHandler extends BmobIMMessageHandler{
/**
* 接收在线消息
* @param messageEvent
*/
@Override
public void onMessageReceive(MessageEvent messageEvent) {
super.onMessageReceive(messageEvent);
final Msg msg = new Msg(messageEvent.getMessage().getContent(), Msg.TYPE_RECEIVED);
msg.setSender(MyUser.getUni());
msg.setReceiver(messageEvent.getFromUserInfo().getUserId());
int len = msg.getContent().length();
// 过滤字符串
String str="=[cn.bmob.newim.event.Message Event@";
String str1="=[cn.bmob.newim.event.MessageEvent@";
String str2 = msg.getContent().trim();
int bl = str2.indexOf(str);
int bo = str2.indexOf(str1);
if(bl!=-1 || bo!=-1){
}else{
if(!msg.getReceiver().equals(Tips.Receiver))
if(len > 10){
String show = msg.getContent().substring(0,8);
//使用EventBus发送通知,主Activity中处理事件
EventBus.getDefault().post(new cn.edu.sau.joker.MessageEvent(msg.getReceiver()+":"+show+"......"));
}else {
EventBus.getDefault().post(new cn.edu.sau.joker.MessageEvent(msg.getReceiver()+":"+msg.getContent()));
}
//聊天界面添加消息
Main.add(msg);
}
}
/**
* 接收离线消息,本程序不做处理
* @param offlineMessageEvent
*/
@Override
public void onOfflineReceive(OfflineMessageEvent offlineMessageEvent) {
super.onOfflineReceive(offlineMessageEvent);
}
}
之前我在MainActivity中写了onMessageEvent方法(方法名字随便写,但是在方法前面要加@Subscribe注解,并且指定线程模型),用来接收事件并进行处理(发送广播):
//发送广播
@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(cn.edu.sau.joker.MessageEvent event) {
Intent intent = new Intent("cn.edu.sau.action.MESSAGE");
intent.putExtra("msg",event.message);
sendBroadcast(intent);
}
然后我们在MylocalMessage(为什么我要起这么个类名,请参考Mainfests中的代码)中接收广播,并发送一个通知,指定铃声和震动事件:
public class MylocalMessage extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// 收到广播时,发送一个通知
String content = intent.getStringExtra("msg");
NotificationManager manager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
Notification notify = new Notification.Builder(context)
.setSmallIcon(R.drawable.icon)
.setContentTitle("您收到一条消息")
.setContentText(content)
.build();
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
notify.sound = uri;
long[] vibrates = { 0, 200, 200, 200 };
notify.vibrate = vibrates;
manager.notify(1, notify);
}
}
整个项目大致就是这样,欢迎大家的评论和指正(虽然我也听不进去),最后放源码和APK .##
