    <p>I want to show a Progress Dialog on button click in my app while data is loaded from the internet. I can't get it to work, could someone give me some tips on where to put the Dialog function?</p> <p>This is my AsyncTask method:</p> <pre><code>private class GetTweets extends AsyncTask&lt;String, Void, String&gt; { @Override protected String doInBackground(String... twitterURL) { //start building result which will be json string StringBuilder tweetFeedBuilder = new StringBuilder(); //should only be one URL, receives array for (String searchURL : twitterURL) { HttpClient tweetClient = new DefaultHttpClient(); try { //pass search URL string to fetch HttpGet tweetGet = new HttpGet(searchURL); //execute request HttpResponse tweetResponse = tweetClient.execute(tweetGet); StatusLine searchStatus = tweetResponse.getStatusLine(); if (searchStatus.getStatusCode() == 200) { //get the response HttpEntity tweetEntity = tweetResponse.getEntity(); InputStream tweetContent = tweetEntity.getContent(); InputStreamReader tweetInput = new InputStreamReader(tweetContent); BufferedReader tweetReader = new BufferedReader(tweetInput); String lineIn; while ((lineIn = tweetReader.readLine()) != null) { tweetFeedBuilder.append(lineIn); } } else tweetDisplay.setText("Error!"); } catch(Exception e){ tweetDisplay.setText("Error!"); e.printStackTrace(); } } //return result string return tweetFeedBuilder.toString(); } protected void onPostExecute(String result) { //start preparing result string for display StringBuilder tweetResultBuilder = new StringBuilder(); try { //get JSONObject from result JSONObject resultObject = new JSONObject(result); //get JSONArray contained within the JSONObject retrieved - "results" JSONArray tweetArray = resultObject.getJSONArray("results"); //loop through each item in the tweet array for (int t=0; t&lt;tweetArray.length(); t++) { //each item is a JSONObject JSONObject tweetObject = tweetArray.getJSONObject(t); tweetResultBuilder.append(tweetObject.getString("from_user")+": "); tweetResultBuilder.append(tweetObject.get("text")+"\n\n"); } } catch (Exception e) { tweetDisplay.setText("Error!"); e.printStackTrace(); } //check result exists if(tweetResultBuilder.length()&gt;0) tweetDisplay.setText(tweetResultBuilder.toString()); else tweetDisplay.setText("no results!"); } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
