这篇说说 TUICallKit 组件通话状态回调的使用。
一、通话状态监听
如果你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，可以参见以下代码示例：
Android（Kotlin）Android（Java）iOS（Swift）iOS（Objective-C）Flutter（Dart）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)}private TUICallObserver observer = new TUICallObserver() { @Override public void onCallBegin(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType, TUICallDefine.Role callRole) { } public void onCallEnd(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType,TUICallDefine.Role callRole, long totalTime) { } public void onUserNetworkQualityChanged(List<TUICommonDefine.NetworkQualityInfo> networkQualityList) { }};private void initData(){ TUICallEngine.createInstance(context).addObserver(observer);}import TUICallEngineTUICallEngine.createInstance().addObserver(self)public func onCallBegin(roomId: TUIRoomId, callMediaType: TUICallMediaType, callRole: TUICallRole) {}public func onCallEnd(roomId: TUIRoomId, callMediaType: TUICallMediaType, callRole: TUICallRole, totalTime: Float) {}public 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 {}TUICallObserver observer = TUICallObserver( onError: (int code, String message) { //你的回调处理逻辑 }, onCallBegin: (TUIRoomId roomId, TUICallMediaType callMediaType, TUICallRole callRole) { //你的回调处理逻辑 }, onCallEnd: (TUIRoomId roomId, TUICallMediaType callMediaType, TUICallRole callRole, double totalTime) { //你的回调处理逻辑 },, onUserNetworkQualityChanged: (List<TUINetworkQualityInfo> networkQualityList) { //你的回调处理逻辑 }, onCallReceived: (String callerId, List<String> calleeIdList, String groupId, TUICallMediaType callMediaType) { //你的回调处理逻辑 } ……))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。
注意：例如：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。
