安卓websocket（客服端和服务端写在app端）案例

废话不多说直接上代码

首选导入

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

java 复制代码

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;


    @Override
    protected 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);
    }

    @Override
    public 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

XML 复制代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/btn1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="客服端" />
