Android SocketClient库的使用

简单介绍：

使用一个开源SocketClient库

地址：https://github.com/vilyever/AndroidSocketClient

参考于：https://blog.csdn.net/jiuyuefenglove/article/details/80089384

Android studio项目中配置：

接着在整个工程的build.gradle里添加如下配置：

buildscript和allprojects下添加：

maven { url "https://jitpack.io" }

repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }

然后还要在app下的build.gradle里配置：

使用新版本导致onResponse一直不回调。后来我使用一个老的版本（2.0.1）

compile 'com.github.vilyever:AndroidSocketClient:2.0.1'

添加权限：

public class MainActivity extends AppCompatActivity {
    private SocketClient socketClient;
    private SocketClientDelegate delegate;
    private EditText et_text;
    private Button btn_send;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        et_text = (EditText) findViewById(R.id.et_text);
        btn_send = (Button) findViewById(R.id.btn_send);
        try {
            startSocketClient("");
        } catch (IOException e) {
            e.printStackTrace();
        }

        btn_send.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String string = et_text.getText().toString().trim();
                if (!TextUtils.isEmpty(string)){
                    socketSendMessage(string);
                    et_text.setText("");
                }

            }
        });
    }

    //socket通信
    private void startSocketClient(String info) throws IOException {
        //String[] array = info.split("_");
       socketClient = new SocketClient();
        //socketClient.getAddress().setRemoteIP(array[0]);//设置IP,这里设置的是本地IP
        //socketClient.getAddress().setRemotePort(String.valueOf(Integer.parseInt(array[1])));//设置端口
        socketClient.getAddress().setRemoteIP("49.4.69.20");//设置IP,这里设置的是本地IP
        socketClient.getAddress().setRemotePort(16018);//设置端口
        socketClient.getAddress().setConnectionTimeout(15 * 1000);//设置超时时间


        //socketClient.setCharsetName(CharsetUtil.UTF_8);//设置编码格式，默认为UTF-8
        socketClient.setCharsetName("GBK");//设置编码格式，默认为UTF-8
        socketClient.connect(); // 连接，异步进行

        //常用回调配置
        // 对应removeSocketClientDelegate
        socketClient.registerSocketClientDelegate(delegate = new SocketClientDelegate() {
            /**
             * 连接上远程端时的回调
             */
            @Override
            public void onConnected(SocketClient client) {
                Log.d("melog", "gamesocket连接成功");
                //launcher.callExternalInterface("gameSocketConnectSuccess", "success");
            }

            /**
             * 与远程端断开连接时的回调
             */
            @Override
            public void onDisconnected(SocketClient client) {
                Log.d("melog", "gamesocket连接断开");
                // 可在此实现自动重连
                 socketClient.connect();
                //launcher.callExternalInterface("socketClose", "close");
            }

            /**
             * 接收到数据包时的回调
             */
            @Override
            public void onResponse(SocketClient client, @NonNull SocketResponsePacket responsePacket) {

                String message = responsePacket.getMessage(); // 获取按默认设置的编码转化的String，可能为null
                Log.i("接收服务端消息：",message);

                //launcher.callExternalInterface("socketDataHandler", message);
            }
        });
    }

    //发送消息
    private void socketSendMessage(String info) {
        String status = String.valueOf(socketClient.getState());
        if (socketClient != null && status == "Connected") {
            socketClient.sendData(info.getBytes()); // 发送byte[]消息
        }
    }

    //前台请求gamesocket连接状态
    private void requestGameSocketConnectFlg() {
        String status = String.valueOf(socketClient.getState());
        //launcher.callExternalInterface("gameSocketFlg", status);
    }

    //前台主动断开gamesocket
    private void closeGameSocket() {
        if (socketClient != null) {
            socketClient.removeSocketClientDelegate(delegate);
            socketClient.disconnect();
        }
    }
}
