接收消息
我这里使用服务来处理消息的接收
IMService
package heath.com.chat.service;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.util.Log;
import com.google.gson.Gson;
import com.netease.nimlib.sdk.NIMClient;
import com.netease.nimlib.sdk.Observer;
import com.netease.nimlib.sdk.friend.model.AddFriendNotify;
import com.netease.nimlib.sdk.msg.MsgServiceObserve;
import com.netease.nimlib.sdk.msg.SystemMessageObserver;
import com.netease.nimlib.sdk.msg.constant.MsgTypeEnum;
import com.netease.nimlib.sdk.msg.constant.SystemMessageType;
import com.netease.nimlib.sdk.msg.model.IMMessage;
import com.netease.nimlib.sdk.msg.model.SystemMessage;
import java.util.List;
import heath.com.chat.message.MessageFragment;
import heath.com.chat.message.SendMessageActivity;
import heath.com.chat.utils.ACache;
public class IMService extends Service {
private static ACache aCache;
private Gson gson;
@Override
public IBinder onBind(Intent intent) {
return new MyBinder();
}
public class MyBinder extends Binder {
// 返回server的实例
public IMService getService() {
return IMService.this;
}
}
@Override
public void onCreate() {
super.onCreate();
aCache = ACache.get(this);
gson = new Gson();
NIMClient.getService(SystemMessageObserver.class).observeReceiveSystemMsg(systemMessageObserver, true);
NIMClient.getService(MsgServiceObserve.class).observeReceiveMessage(incomingMessageObserver, true);
}
@Override
public void onDestroy() {
super.onDestroy();
NIMClient.getService(SystemMessageObserver.class).observeReceiveSystemMsg(systemMessageObserver, false);
NIMClient.getService(MsgServiceObserve.class).observeReceiveMessage(incomingMessageObserver, false);
}
Observer<SystemMessage> systemMessageObserver = new Observer<SystemMessage>() {
@Override
public void onEvent(SystemMessage systemMessage) {
if (systemMessage.getType() == SystemMessageType.AddFriend) {
AddFriendNotify attachData = (AddFriendNotify) systemMessage.getAttachObject();
if (attachData != null) {
// 针对不同的事件做处理
if (attachData.getEvent() == AddFriendNotify.Event.RECV_ADD_FRIEND_DIRECT) {
// 对方直接添加你为好友
} else if (attachData.getEvent() == AddFriendNotify.Event.RECV_AGREE_ADD_FRIEND) {
// 对方通过了你的好友验证请求
} else if (attachData.getEvent() == AddFriendNotify.Event.RECV_REJECT_ADD_FRIEND) {
// 对方拒绝了你的好友验证请求
} else if (attachData.getEvent() == AddFriendNotify.Event.RECV_ADD_FRIEND_VERIFY_REQUEST) {
// 对方请求添加好友,一般场景会让用户选择同意或拒绝对方的好友请求。
// 通过message.getContent()获取好友验证请求的附言
}
}
}
}
};
private Observer<List<IMMessage>> incomingMessageObserver =
new Observer<List<IMMessage>>() {
@Override
public void onEvent(List<IMMessage> messages) {
// 处理新收到的消息,为了上传处理方便,SDK 保证参数 messages 全部来自同一个聊天对象。
for (IMMessage message : messages) {
Log.i("message", "onEvent===========: " + message.getContent());
if (message.getMsgType() == MsgTypeEnum.text) {
SendMessageActivity.updateData(message.getContent());
}
}
}
};
}
使用了服务,记得在AndroidManifest.xml注册一下
<service android:name=".service.IMService" />
记得在LoginActivity里,登录后启动一下
Intent server = new Intent(LoginActivity.this,
IMService.class);
startService(server);
