android apk实现pc端与手机端的远程连接

由于平常工作中经常需要使用adb 连接，那么问题来了，如果一台电脑需要连接多台手机，使用传统的USB连接的方式就不方便了。这时，就需要无线连接了。目前我所知的无线连接有两种：

1.利用android studio的adb wify插件可以进行多台机器的远程连接，该方式后续文章会提到
2.手机端进入adb shell 开通adbd端口setprop service.adb.tcp.port 5555
PC端的dos命令输入adb connect 手机端ip地址，即可连接

原理就是这样子，代码的实现方式就是第二种，使用该方式的手机必须是需要root权限的，废话不多说了，以下是代码：

1.布局文件，一个按钮，一个显示文本，代码如下

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
  >

    <LinearLayout
        android:layout_width="match_parent"
        android:orientation="horizontal"
        android:layout_height="50dp">


        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:id="@+id/tv_ip"
            android:layout_weight="1"/>

        <Button
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/button_connect"
            android:text="远程调试"
            android:layout_weight="3"/>

    </LinearLayout>
</RelativeLayout>

2.MainActivity代码如下

package com.example.administrator.connectdemo;

import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    Button button_connect;
    TextView tv_ip;
    private Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button_connect=(Button)findViewById(R.id.button_connect);
        tv_ip=(TextView)findViewById(R.id.tv_ip);
        button_connect.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                new Thread() {
                    @Override
                    public void run() {//在run()方法实现业务逻辑；
                        //...

                        //更新UI操作；
                        handler.post(new Runnable() {
                            @Override
                            public void run() {
                                try{
                                    //获取无线的ip相关信息
                                    String ipString=ShellUtils.execCommand(new String[]{"ifconfig wlan0"},true,true).successMsg;
                                    //截取ip地址
                                    String ip=ipString.substring(ipString.indexOf("inet addr")+10,ipString.indexOf("Bcast")-2);
                                    tv_ip.setText("adb connect "+ip+":5555远程连接");

                                    //开启adbd端口

                                    ShellUtils.execCommand("setprop service.adb.tcp.port 5555",true);
                                }
                                catch (StringIndexOutOfBoundsException e){
                                    Toast toast=Toast.makeText(MainActivity.this, "wify未连接", Toast.LENGTH_SHORT);
                                    toast.show();
                                }





                            }
                        });

                    }
                }.start();

            }
        });



    }
}
