我想写一个应用程序在同一个wifi网络上的2个Android设备之间传输数据,就像有一个共享文件夹一样。
我该怎么做?
由于
编辑(我的解决方案):
我的服务器等待请求
private boolean startServer() {
try {
server = new ServerSocket(port);
} catch (IOException ex) {
ex.printStackTrace();
return false;
}
return true;
}
public void runServer() {
while (this.go) {
try {
Log.d("BurgerClub", "Server in attesa di richieste");
Socket s1 = server.accept();
OutputStream s1out = s1.getOutputStream();
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(
s1out));
BufferedReader br = new BufferedReader(new FileReader(this.path));
String counter = br.readLine();
counter = counter != null ? counter : "000";
br.close();
bw.write(counter);
bw.close();
s1.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
我的客户端(Runnable对象)
public void run() {
try {
this.openConnection();
// Se il socket è connesso
if( !this.s1.isClosed() ) {
InputStream is = this.s1.getInputStream();
BufferedReader dis = new BufferedReader(new InputStreamReader(is));
line = dis.readLine();
if( !this.previousCounter.equals(line.trim()) ) {
((BurgerClub_MonitorActivity) counterContext).runOnUiThread(new Runnable() {
@Override
public void run() {
TextView edit = (TextView)(((BurgerClub_MonitorActivity) counterContext).findViewById(R.id.textActionCounter));
edit.setText(line);
}
});
this.previousCounter = line.trim();
}
dis.close();
}
} catch (ConnectException connExc) {
connExc.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} catch (Throwable ex) {
ex.printStackTrace();
}

一台设备需要作为服务器,另一台设备需要作为客户端。
基本流程必须属于这种类型:
