Body
<p>Just for some inspiration, here is the general code format that I have used successfully to show a horizontal progress bar which updates while a background task is running. I know it doesn't answer your exact question, but I hope it helps you to find your solution. </p> <pre><code>ProgressDialog myProgressDialog; private void someFunctionThatStartsTheAsyncTask() { new myBackgroundTask.execute(someIntegerArgument); } private class myBackgroundTask extends AsyncTask<Integer, Integer, Boolean> { protected void onPreExecute() { myProgressDialog = new ProgressDialog(myContext); myProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); myProgressDialog.setTitle("Doing something in background..."); myProgressDialog.setMessage("Please wait..."); myProgressDialog.setCancelable(false); myProgressDialog.setIndeterminate(false); myProgressDialog.setMax(100); myProgressDialog.setProgress(0); myProgressDialog.show(); } protected Boolean doInBackground(Integer... params) { int someVariable = params[0]; boolean success; for (whatever loop conditions) { // some long-running stuff, setting 'success' at some point ... publishProgress(newPositionForProgressBar); } return success; } protected void onProgressUpdate(Integer... progressPosition) { myProgressDialog.setProgress(progressPosition[0]); } protected void onPostExecute(Boolean result) { myProgressDialog.dismiss(); if (result) { //doInBackground returned true } else { //doInBackground returned false } } } </code></pre>

1. COthanks for the code :) i am still trying to think, maybe i got the whole asynctask thing wrong. maybe i shouldn't call functions that are on outside classes and calling other functions. maybe the whole code have to be Exclusive for the doInBackgroun(). but it seems unlogical to me. i think that it i were calling some functions that update the UI in some way,i would be getting an error try to operate them from the doInBackground.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
