关于android下实现FTP多线程下载的功能

Question

android下能否实现ftp多线程现在的功能呢？研究中发现一个文件进行多线程下载有一定的难度，有没有做过的哥们，指点一下。谢谢！

Answer 1

了解一下AsyncTask
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);       
   setContentView(R.layout.main);    this.pd = ProgressDialog.show(this, "Working...", "*** Downloading Data...", true, false);
    new DownloadTask().execute(" parameters needed for download");
}private class DownloadTask extends AsyncTask<String, Void, Object> {
     protected Void doInBackground(String... args) {
        //Background thread starting......
         startLongRunningOperation();   
        return null;         
     }     protected void onPostExecute(Object result) {         if (Splash.this.pd != null) {
          Splash.this.pd.dismiss();
         }
         updateResultsInUi();     }
} 
protected void startLongRunningOperation() {
             try
             {
             ftp = new FTPClient();
             ftp.connect(host);
             ftp.login("username", "password");
             ftp.changeDirectory("public_ftp");
       ftp.download("test.txt", new java.io.File("/sdcard/test.txt")); 
             }
      catch(Exception e)
      {                      }
}
