安卓websocket（客服端和服务端写在app端）案例

news 2025/8/22 7:51:16

废话不多说直接上代码

首选导入

    implementation "org.java-websocket:Java-WebSocket:1.4.0"

package com.zx.qnncpds.androidwbsocket;import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;import androidx.appcompat.app.AppCompatActivity;import com.zx.qnncpds.androidwbsocket.client.ClientActivity;
import com.zx.qnncpds.androidwbsocket.service.ServiceActivity;public class MainActivity extends AppCompatActivity implements View.OnClickListener {private Button btn1;private Button btn2;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btn1 = findViewById(R.id.btn1);btn2 = findViewById(R.id.btn2);btn1.setOnClickListener(this);btn2.setOnClickListener(this);}@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.btn1://客户端startActivity(new Intent(MainActivity.this, ClientActivity.class));break;case R.id.btn2://服务端startActivity(new Intent(MainActivity.this, ServiceActivity.class));break;default:break;}}
}

布局

客服端

import android.view.View;
import android.widget.Button;import com.zx.qnncpds.androidwbsocket.R;import java.net.URI;

布局加一个文本这就不写了（服务端和客服端都一样）
