监控通话状态

本文介绍 TUICallKit 组件通话状态回调的使用。
通话状态监听
如果您的业务需要监听通话的状态，例如通话开始、结束等通话过程中的事件，可以参考如下代码：
Android（Kotlin）
Android（Java）
iOS（Swift）
iOS（Objective-C）
Flutter（Dart）
import com.tencent.qcloud.tuikit.TUICommonDefine
import com.tencent.qcloud.tuikit.tuicallengine.TUICallDefine
import com.tencent.qcloud.tuikit.tuicallengine.TUICallEngine
import com.tencent.qcloud.tuikit.tuicallengine.TUICallObserver
﻿
private val observer: TUICallObserver = object : TUICallObserver() {
    override fun onCallBegin(roomId: TUICommonDefine.RoomId?, callMediaType: TUICallDefine.MediaType?, callRole: TUICallDefine.Role?) {
    }
    override fun onCallEnd(roomId: TUICommonDefine.RoomId?, callMediaType: TUICallDefine.MediaType?, callRole: TUICallDefine.Role?, totalTime: Long) {
    }   
    override fun onUserNetworkQualityChanged(networkQualityList: MutableList<TUICommonDefine.NetworkQualityInfo>?) {    
    }
}
private fun initData() {
    TUICallEngine.createInstance(context).addObserver(observer)
}
import com.tencent.qcloud.tuikit.TUICommonDefine;
import com.tencent.qcloud.tuikit.tuicallengine.TUICallDefine;
import com.tencent.qcloud.tuikit.tuicallengine.TUICallEngine;
import com.tencent.qcloud.tuikit.tuicallengine.TUICallObserver;
﻿
private TUICallObserver observer = new TUICallObserver() {
    @Override
    public void onCallBegin(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType, TUICallDefine.Role callRole) {
    }
    @Override
    public void onCallEnd(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType,TUICallDefine.Role callRole, long totalTime) {
    }
    @Override
    public void onUserNetworkQualityChanged(List<TUICommonDefine.NetworkQualityInfo> networkQualityList) {
    }
};
﻿
private void initData(){
    TUICallEngine.createInstance(context).addObserver(observer);
}
import TUICallEngine
﻿
TUICallEngine.createInstance().addObserver(self)
﻿
func onCallBegin(roomId: TUIRoomId, callMediaType: TUICallMediaType, callRole: TUICallRole) {
﻿
}
﻿
func onCallEnd(roomId: TUIRoomId, callMediaType: TUICallMediaType, callRole: TUICallRole, totalTime: Float) {
﻿
}
﻿
func onUserNetworkQualityChanged(networkQualityList: [TUINetworkQualityInfo]) {
﻿
}
#import <TUICallEngine/TUICallEngine.h>
﻿
[[TUICallEngine createInstance] addObserver:self];
﻿
- (void)onCallBegin:(TUIRoomId *)roomId callMediaType:(TUICallMediaType)callMediaType callRole:(TUICallRole)callRole {
﻿
}
﻿
- (void)onCallEnd:(TUIRoomId *)roomId callMediaType:(TUICallMediaType)callMediaType callRole:(TUICallRole)callRole totalTime:(float)totalTime {
﻿
}
﻿
- (void)onUserNetworkQualityChanged:(NSArray<TUINetworkQualityInfo *> *)networkQualityList {
﻿
}
import 'package:tencent_calls_engine/tencent_calls_engine.dart';
﻿
TUICallObserver observer = TUICallObserver(
    onError: (int code, String message) {
      
    }, onCallBegin: (TUIRoomId roomId, TUICallMediaType callMediaType, TUICallRole callRole) {
      
    }, onCallEnd: (TUIRoomId roomId, TUICallMediaType callMediaType, TUICallRole callRole, double totalTime) {  
﻿
    }, onUserNetworkQualityChanged: (List<TUINetworkQualityInfo> networkQualityList) {
     
    }, onCallReceived: (String callerId, List<String> calleeIdList, String groupId, TUICallMediaType callMediaType) {
﻿
    }
))
﻿
void addObserver() {
    TUICallEngine.instance.addObserver(observer);
}
注意：
在 Android 平台设置 TUICallObserver 监听回调，需保证回调所在类不会被清除，举例：不建议在 LoginActivity 中添加监听，LoginActivity 销毁的时候，回调也会被清除；建议在应用的 Application 中或者应用主界面进行监听。
