Question

我正在开发一个Android应用程序，我需要连接到Web套接字并接收消息以从Web服务器解锁应用程序。接收消息已通过Stompclient在java脚本上实现，但我需要在Android上执行相同的操作。我读到了关于Okhttp3及其对web socket的支持，所以我能够实现它websocket正在打开，但我不知道如何订阅在Android上接收消息。

public class LockScreenActivity extends AppCompatActivity implements ServerConnection.ServerListener{
    private ServerConnection mServerConnection;
    private JSONObject jsonObject;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_lock_screen);
        mServerConnection = new ServerConnection(TerminalDetails.WEB_SOCKET_URL);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
                WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);

       Timer timer = new Timer();
       timer.schedule(timerTask, 10000);
    }

    @Override
    protected void onResume() {
        super.onResume();
        mServerConnection.connect(this);
        mServerConnection.sendMessage("Hello, Testing Connection!");
        Utility.showToast(this, "Connected to the Web Socket");
    }

    @Override
    public void onNewMessage(String message) {
        try {
            Utility.showToast(this, "A new message received!");
            jsonObject = new JSONObject(message);
        } catch (JSONException e) {
            Utility.stringify(e);
        }
        validateResponse(jsonObject);
    }

我的Android实施：

Dim dict As Object
Set dict = CreatObject("Scripting.Dictionary")

    If .Cells(.Rows.Count, "L").End(xlUp).Row > 5 Then If .Cells(.Rows.Count, "L").End(xlUp).Row > 5 Then last = .Cells(.Rows.Count, "L").End(xlUp).Row Else last = 5 Else last = 5
    Set rData = .Range("L5:L" & last & ",AX5:AX" & last)
    For i = rData.Row To rData.Row + rData.Rows.Count - 1
        If Not .Cells(i, "L").Value = "" Then If Not dict.Exists(.Cells(i, "L").Value) Then dict(.Cells(i, "L").Value) = .Cells(i, "AX").Value


    Next i
    .Parent.Close False
End With

需要从服务器接收解锁消息的LockScreenActivity：

parentNavigate(destination){
 this.props.navigation.navigate(destination);
}

render(){
        if(this.state.isLoading){
            ...
        }
        return (
            <View>
                <Strip props={this.state.dataSource.strips} parentNavigate={(destination) => this.parentNavigate(destination)}/>
            </View>
        )
    }

如果需要，我会回答有关代码的更多问题。感谢
