How to add ProgressDialog

Question

I am downloading a file from dropbox which is taking a few seconds. I want to add a ProgressDialog for the download but I don\'t know how to do that.

Answer 1

Do it this way:

public final class DownloadFile extends AsyncTask {

private Context context;
private ProgressDialog progressDialog;

public DownloadFile (Context context) {
    this.context = context;
}

/* 
 * @see android.os.AsyncTask#onPreExecute()
 */
@Override
protected void onPreExecute() {
    try {
        progressDialog = ProgressDialog.show(context, "", "message", true);
    } catch (final Throwable th) {
        //TODO
    }
}

/* 
 * @see android.os.AsyncTask#doInBackground(Params[])
 */
@Override
protected Boolean doInBackground(Void... arg0) {
    //do something
}

    @Override
protected void onProgressUpdate(String... progress) {
    //do something
    super.onProgressUpdate(progress);
}

/* 
 * @see android.os.AsyncTask#onPostExecute(java.lang.Object)
 */
@Override
protected void onPostExecute(Boolean result) {
    progressDialog.dismiss();
} }
