Question

我在Xamarin上做了一个跨平台项目。想出了这个问题。我有一个TabActivity（包含4个Framgents（Request，Info，Fav，Settings）。还有一个TcpController，它只不过是一个带有一堆异步任务的类。如果你看下面的方法：

public async Task Read( ) {
    await socketListener.StartListeningAsync( port );
    socketListener.ConnectionReceived += async ( sender, args ) => {
        var client = args.SocketClient;
        await Task.Delay( 2000 );
        while (true) {

            System.Console.WriteLine( "Testing.." );
            //Read from the ReadStream property of the socket client to receive data
            if (client.ReadStream.CanRead) {
                await Task.Run( ( ) => client.ReadStream.ReadAsync( dataSet, 0, dataSet.Length ) );
                netObj = networkObjectAdapter.ByteArrayToObject( dataSet );
                if (netObj.command == NetworkCommand.RECEIVE_LIST) {

                    Message msg = new Message( );
                    msg.Obj = dataSet;
                    requestFragmentHandler.SendMessage( msg );

                } else if (netObj.command == NetworkCommand.RECEIVE_VOTE_SONG) {
                    Message msg = new Message( );
                    msg.Obj = dataSet;
                    requestFragmentHandler.SendMessage( msg );
                }
                //other business logic
            }
            await args.SocketClient.DisconnectAsync( );
            break;

        }
    };
}

正如你在if语句中看到的那样，当收到一些东西时，我使用RequestFragmentHandler向它发送一条消息，虽然我不确定是否有f.e.每个片段的3个处理程序对Android架构有意义。如果让一堆处理程序处理片段和Tcp Controller之间的通信是一个糟糕的系统决策，那么什么是不阻止UI的最佳方法？

Xamarin.Android太多处理程序反效果？
