自定义Android Socket Client Helper 简单实现

初使化

public class SocketClientHelper {
    
    

    private Socket socket;
    private String serverIp;
    private int serverPort;

    public SocketClientHelper() {
    
    
        
    }
}

StartConnect

/**
 * 根據傳入的IP和Port開啟Socket連接，根據返回的結果判斷是否連接成功
 *
 * @param serverIp
 * @param serverPort
 * @return
 */
public boolean StartConnect(String serverIp, int serverPort) {
    
    
    this.serverIp = serverIp;
    this.serverPort = serverPort;
    try {
    
    
        FutureTask<Boolean> futureTask = new FutureTask<Boolean>(callable);
        new Thread(futureTask).start();
        return futureTask.get();
    } catch (InterruptedException | ExecutionException ee) {
    
    
        ee.printStackTrace();
        return false;
    }
}

//開啟Socket連接并返回值
Callable callable = new Callable() {
    
    
    @Override
    public Object call() {
    
    
        try {
    
    
            socket = new Socket(serverIp, serverPort);
        } catch (Exception e) {
    
    
            e.printStackTrace();
            return false;
        }
        return true;
    }
};

StopConnect

/**
 * 關閉當前socket連接
 */
public void StopConnect() {
    
    
    if (socket != null) {
    
    
        try {
    
    
            socket.shutdownOutput();
            socket.close();
        } catch (IOException e) {
    
    
            e.printStackTrace();
        }
        socket = null;
    }
}

SendMessage

/**
 * 發送消息到服務端
 *
 * @param msg
 */
public void SendMessage(String msg) {
    
    
    try {
    
    
        if (socket.isConnected()) {
    
    
            if (!socket.isOutputShutdown()) {
    
    
                PrintWriter printWriter = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()), true);
                printWriter.println(msg);
            }
        }
    } catch (IOException e) {
    
    
        e.printStackTrace();
    }
}
