我的Android进阶之旅------>Android实现用Android手机控制PC端的关机和重启的功能（二）Android客户端功能展示
（地址：http://blog.csdn.net/ouyang_peng/article/details/47005739）
通过以上两篇文章，我们了解了Android实现用Android手机控制PC端的关机和重启的的大概功能，现在我们来实现Android客户端的代码。
首先来看看整个项目的结构，如下图所示：
第一步：扫描局域网内所有PC,看是否有PC端的服务器在运行并监听30000端口。
此界面的布局文件为：/res/layout/layout_scanip.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:id="@+id/ll"
android:layout_width="200dp"
android:layout_height="100dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/scaning" />
<ProgressBar
android:id="@+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="100dp"
android:layout_height="1dp" />
</LinearLayout>
</RelativeLayout>
</RelativeLayout>
扫描IP的Activity为com.oyp.shutdown.ScanActivity，代码如下：
package com.oyp.shutdown;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.Socket;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.Window;
import android.widget.ProgressBar;
import android.widget.Toast;
public class ScanActivity extends Activity {
private MyWifiManager myWifiManager = null;
private String serverIP = "", resultIP = "";
private ScanIPThread scanThread = null;
private ProgressBar progressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
int height = getWindow().getWindowManager().getDefaultDisplay()
.getHeight();
int width = getWindow().getWindowManager().getDefaultDisplay()
.getWidth();
setContentView(R.layout.layout_scanip);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
myWifiManager = new MyWifiManager(ScanActivity.this);
scanThread = new ScanIPThread();
scanThread.start();
}
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 1000:
Toast.makeText(ScanActivity.this, getString(R.string.find),
Toast.LENGTH_SHORT).show(); // 找到可连接PC
Intent controlIntent = new Intent(ScanActivity.this,
ControlActivity.class);
// 将可以连接的ip发过去
controlIntent.putExtra("ip", (String) msg.obj);
startActivity(controlIntent);
finish();
break;
case 2000:
Toast.makeText(ScanActivity.this, getString(R.string.notFind),
Toast.LENGTH_SHORT).show(); // 没有找到可连接PC
Intent reScanIntent = new Intent(ScanActivity.this,
ReScanActivity.class);
startActivity(reScanIntent);
finish();
break;
default:
progressBar.setMax(254);
progressBar.setProgress(msg.what);
break;
}
super.handleMessage(msg);
}
};
// 扫描连接的WiFi所在网段开启了30000端口的C类ip
// 例如，wifi的ip是192.168.1.1 则扫描 192.168.1.1-192.168.1.254
class ScanIPThread extends Thread {
@Override
public void run() {
serverIP = myWifiManager.getServerIp();
int t = serverIP.lastIndexOf(".") + 1;
resultIP = serverIP.substring(0, t);
boolean flag = false;
for (int i = 1; i < 255; i++) {
try {
Socket socket = new Socket();
InetSocketAddress s = new InetSocketAddress(resultIP + i,
30000);
socket.connect(s, 50);
Message message = new Message();
message.what = 1000;
message.obj = resultIP + i;
handler.sendMessage(message);
flag = true;
socket.close();
break;
} catch (IOException e) {
handler.sendEmptyMessage(i);
}
}
if (!flag) {
handler.sendEmptyMessage(2000);
}
super.run();
}
}
}
第二步：如果没有扫描到有PC端的服务器在运行并监听30000端口，则重新扫描或者退出。如上述代码中，当msg.what=2000时，重新进行扫描。
此界面的布局文件为：/res/layout/layout_rescan.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Button
android:id="@id/btnReScan"
style="@style/StyleButton"
android:text="@string/rescan" />
<Button
android:id="@id/btnClose"
style="@style/StyleButtonClose"
android:text="@string/close" />
</LinearLayout>
重新扫描IP的Activity为com.oyp.shutdown.ReScanActivity，代码如下：
package com.oyp.shutdown;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;
public class ReScanActivity extends Activity implements OnClickListener {
private Button btn_rescan, btn_close;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_LEFT_ICON);
setContentView(R.layout.layout_rescan);
getWindow().setFeatureDrawableResource(Window.FEATURE_LEFT_ICON,
R.drawable.acticon);
btn_rescan = (Button) findViewById(R.id.btnReScan);
btn_close = (Button) findViewById(R.id.btnClose);
btn_rescan.setOnClickListener(this);
btn_close.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnReScan:
Intent intent = new Intent(ReScanActivity.this,ScanActivity.class);
startActivity(intent);
finish();
break;
case R.id.btnClose:
finish();
break;
default:
break;
}
}
}
第二步：扫描到了有PC端的服务器在运行并监听30000端口，则控制PC端关机、重启或者取消关机。如上述代码中，当msg.what=1000时，则打开控制PC端界面。
此界面的布局文件为：/res/layout/layout_control.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Button
android:id="@id/btnShutdown"
style="@style/StyleButton"
android:text="@string/shutdown" />
<Button
android:id="@id/btnReboot"
style="@style/StyleButton"
android:text="@string/reboot" />
<Button
android:id="@id/btnCancel"
style="@style/StyleButton"
android:text="@string/cancel" />
<Button
android:id="@id/btnClose"
style="@style/StyleButtonClose"
android:text="@string/close" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="6.0dip"
android:text=" "
android:textSize="12.0dip" />
</LinearLayout>
控制PC端的Activity为com.oyp.shutdown.ControlActivity，代码如下：
package com.oyp.shutdown;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;
import android.widget.Toast;
public class ControlActivity extends Activity implements OnClickListener {
private Button btn_shutdown, btn_restart, btn_cancel, btn_close;
private Socket clientSocket;// 客户端socket
private DataOutputStream dataOutput = null;// 客户端发送数据
private DataInputStream dataInput = null;// 客户端接收数据
private String connIP = "";
private ConnThread connThread = null;
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 1:
Toast.makeText(ControlActivity.this, (String) msg.obj,
Toast.LENGTH_SHORT).show();
break;
default:
break;
}
super.handleMessage(msg);
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_LEFT_ICON);
setContentView(R.layout.layout_control);
getWindow().setFeatureDrawableResource(Window.FEATURE_LEFT_ICON,
R.drawable.acticon);
btn_shutdown = (Button) findViewById(R.id.btnShutdown);
btn_restart = (Button) findViewById(R.id.btnReboot);
btn_cancel = (Button) findViewById(R.id.btnCancel);
btn_close = (Button) findViewById(R.id.btnClose);
Intent intent = getIntent();
connIP = intent.getStringExtra("ip");
btn_shutdown.setOnClickListener(this);
btn_restart.setOnClickListener(this);
btn_cancel.setOnClickListener(this);
btn_close.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// 连接服务器
switch (v.getId()) {
case R.id.btnShutdown:
final String shutdown = "shutdown";
if (connThread != null) {
connThread.interrupt();
}
connThread = new ConnThread(connIP, 30000, shutdown);
connThread.start();
break;
case R.id.btnReboot:
final String reboot = "reboot";
if (connThread != null) {
connThread.interrupt();
}
connThread = new ConnThread(connIP, 30000, reboot);
connThread.start();
break;
case R.id.btnCancel:
final String cancel = "cancel";
if (connThread != null) {
connThread.interrupt();
}
connThread = new ConnThread(connIP, 30000, cancel);
connThread.start();
break;
case R.id.btnClose:
finish();
break;
default:
break;
}
}
class ConnThread extends Thread {
private String ip;
private int port;
private String content;
public ConnThread(String ip, int port, String content) {
this.ip = ip;
this.port = port;
this.content = content;
}
@Override
public void run() {
try {
clientSocket = new Socket(ip, port);
while (true) {
dataOutput = new DataOutputStream(
clientSocket.getOutputStream());
dataInput = new DataInputStream(
clientSocket.getInputStream());
String msg = "";
if ((dataOutput != null) && (!content.equals(""))) {
dataOutput.writeUTF(content);
}
msg = dataInput.readUTF();
if (msg != null && !"".equals(msg)) {
Message message = new Message();
message.what = 1;
message.obj = msg;
handler.sendMessage(message);
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (dataOutput != null) {
dataOutput.close();
}
if (dataInput != null) {
dataInput.close();
}
if (clientSocket != null) {
clientSocket = null;
}
} catch (IOException e) {
e.printStackTrace();
}
}
super.run();
}
}
}
其中MyWifiManager.java代码如下：
package com.oyp.shutdown;
import android.content.Context;
import android.net.DhcpInfo;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
public class MyWifiManager {
private WifiManager wifiManager;
private WifiInfo wifiInfo;
private DhcpInfo dhcpInfo;
public MyWifiManager(Context context){
wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiInfo = wifiManager.getConnectionInfo();
dhcpInfo = wifiManager.getDhcpInfo();
}
//得到本机ip
public String getLocalIp(){
return FormatString(dhcpInfo.ipAddress);
}
//得到服务器ip（热点ip）
public String getServerIp(){
return FormatString(dhcpInfo.serverAddress);
}
//转换ip格式为*.*.*.*
public String FormatString(int value){
String strValue="";
byte[] ary = intToByteArray(value);
for(int i=ary.length-1;i>=0;i--){
strValue+=(ary[i]&0xFF);
if(i>0){
strValue+=".";
}
}
return strValue;
}
public byte[] intToByteArray(int value){
byte[] b=new byte[4];
for(int i=0;i<4;i++){
int offset = (b.length-1-i)*8;
b[i]=(byte) ((value>>>offset)&0xFF);
}
return b;
}
}
