Question

I created a Progress bar but I can’t see the loading animation. It’s frozen. I want to display a progress bar when I click on the item and then see the bar working and not frozen. Here is my code:

     lv.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
           if (((TextView) view).getText().equals("Zman-New (rus)")){

               progDailog = ProgressDialog.show(testLoading.this, "Getting data", "Loading...",true,true);
               new GetDataTask("stringurl.xml").execute();

              }

Here is the getdata

 private class GetDataTask extends AsyncTask<Void, Void, Integer> {
String url;
GetDataTask(String url){
    this.url=url;
}
@Override
protected Integer doInBackground(Void... params) {
        //do all your backgroundtasks 
      intent = new Intent(rusNewsP.testLoading.this, rusNewsTest.rusNewsActivite.class);
      intent.putExtra("url",url);
      startActivity(intent);
      finish();
        return 1;
}

@Override
protected void onPostExecute(Integer result) {

        //finish up ( or close the progressbar )

        //do something with the result
    progDailog.dismiss();
        super.onPostExecute(result);
}
 }

If you just want to test Progress try this:

private class Initialize extends AsyncTask<Short, Short, Short> {
            ProgressDialog pd;



@Override
protected void onPreExecute() {
    pd = new ProgressDialog(yourlass.this);
    pd.setMessage("test");
    pd.show();
    super.onPreExecute();
}

@Override
protected Short doInBackground(Short... params) {
    try {
    synchronized (this) {
        wait(2000);
    }
    } catch (InterruptedException ex) {
    }
    return null;
}

@Override
protected void onPostExecute(Short result) {
    pd.dismiss();
    super.onPostExecute(result);
}
}

And don’t call startActivity in the doInBackground-Method. Call it in OnPostExecute instead. GUI Operations should not be done in doInBackground.
