java - 如何检查 WebSocket 是否已连接

Question

我使用 KOUSH 库创建了一个 Websocket 服务类 https://github.com/koush/AndroidAsync#can-also-create-web-sockets

现在我想检查 Websocket 是否从我的 mainActivity 连接到我的服务器。你知道我怎么检查这个吗？谢谢

AsyncHttpClient.getDefaultInstance().websocket(get, "my-protocol", new WebSocketConnectCallback() {
    @Override
    public void onCompleted(Exception ex, WebSocket webSocket) {
        if (ex != null) {
            ex.printStackTrace();
            return;
        }
        webSocket.send("a string");
        webSocket.send(new byte[10]);
        webSocket.setStringCallback(new StringCallback() {
            public void onStringAvailable(String s) {
                System.out.println("I got a string: " + s);
            }
        });
        webSocket.setDataCallback(new DataCallback() {
            public void onDataAvailable(ByteBufferList byteBufferList) {
                System.out.println("I got some bytes!");
                // note that this data has been read
                byteBufferList.recycle();
            }
        });
    }
});

你可以这样做:

if (mWebSocketClient.isOpen) {
         mWebSocketClient.send(jObj.toString())
} else {
   try {
         client.connectWebSocket(p0)
         mWebSocketClient.send(jObj.toString())
   } catch (e : Exception){
        Toast.makeText(p0, "not connected $e", Toast.LENGTH_LONG).show()
   }
}
