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！

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)
{
}
}
