    <p>This is so simple. The basic fact behind this is as follows.</p> <p>Your progress dialog runs in the main UI. Your <code>for</code> loop here gets executed so soon and takes more priority and hence you are not able to see your progress dialog but the fact is, your code works fine and progress dialog does show up for fraction of seconds which the human eye can't catch.</p> <p>Usually people use a progress dialog when they do something in the background thread and not the main thread. So you will have to change a little bit of your code. They are,</p> <p>1) Surround your <code>for</code> loop with a thread like this,</p> <pre><code> Button end = (Button) findViewById(R.id.button2); end.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { ProgressDialog pd = new ProgressDialog(ZiiziiActivity.this); pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); pd.setMessage("Working..."); pd.setIndeterminate(true); pd.setCancelable(false); pd.show(); Thread t = new Thread(new Runnable() { @Override public void run() { for (int i=0;i&lt;1000000;i++) { Thread.sleep(100); //To denote a delay in background processing } handler.sendEmptyMessage(0); } }); t.start(); } }); </code></pre> <p>2) Now add a handler to your onCreate() like this:</p> <pre><code> handler = new Handler() { public void handleMessage(Message msg) { if (msg.what == 0) { pd.dismiss(); } }; </code></pre> <p>Note that you can't update your UI from a background thread. So in order to update the UI from some other worker thread you go for handlers. So once your for loop gets completed, a call will be made to handlers which updates the UI. (In this case it cancels the progress dialog).</p>

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.
