Hi,
I was wondering if someone could help me with my asynctask? I have a
problem with onPostExecute and onCancelled. onPostExecute seems to be
skipped everytime I run the asynctask, the file downloads, no problem,
but the dialog is still there. As for the cancel button, it doesn't
seem to reach onCancelled. Can anyone wee what I'm doing wrong?
/André
protected class DownloadTask extends AsyncTask<Context, Integer,
Void>{
private Dialog dialogD;
private ProgressBar downloadBar;
private ImageButton cancel;
OnClickListener listen = new OnClickListener() {
@Override
public void onClick(View v) {
if(v == cancel) {
downloadTask.cancel(true);
}
}
};
@Override
protected void onPreExecute() {
super.onPreExecute();
// Context mContext = getApplicationContext();
dialogD = new Dialog(SilverFTP.this);
dialogD.setContentView(R.layout.silver_ftp_downloading);
dialogD.setTitle("Downloading...");
TextView info = (TextView)
dialogD.findViewById(R.id.download_info);
info.setText(fileName);
downloadBar = (ProgressBar)
dialogD.findViewById(R.id.download_bar);
cancel = (ImageButton)
dialogD.findViewById(R.id.cancel_download);
cancel.setOnClickListener((OnClickListener) this);
dialogD.show();
logg.append("onPreExecute" + "\n");
Log.i("makemachine", "onPreExecute()");
}
@Override
protected Void doInBackground(final Context... params) {
try {
InputStream stO = new
BufferedInputStream(client.retrieveFileStream(fileToUse),
client.getBufferSize());
OutputStream stD = new FileOutputStream(placeToPaste);
while (ftpTotal < ftpSize) {
Util.copyStream(stO, stD, client.getBufferSize(),
CopyStreamEvent.UNKNOWN_STREAM_SIZE, new CopyStreamAdapter(){
public void bytesTransferred(long
totalBytesTransferred, int bytesTransferred, long streamSize) {
double tempProgress =
(((double)totalBytesTransferred / (double)ftpSize) * 100.0);
int progress = (int) tempProgress;
publishProgress(progress);
}
});
}
client.completePendingCommand();
} catch (IOException e) {
logg.append("Download IOExc, download()" +
"\n");
e.printStackTrace();
}
return null;
}
protected void onProgressUpdate(final Integer... values) {
downloadBar.setProgress(values[0]);
Log.i("makemachine", "onProgressUpdate(): " +
String.valueOf(values[0]));
}
@Override
protected void onCancelled() {
super.onCancelled();
downloadTask.dialogD.dismiss();
}
@Override
protected void onPostExecute(Void v) {
logg.append("onPostExecute" + "\n");
downloadTask.dialogD.dismiss();
}
}
