How can I pass or get the result to my main Activity?</p> <p>Here is the sample codes.</p> <p>My main Activity.</p> <pre><code>public class MainActivity extends Activity{ AasyncTask asyncTask = new AasyncTask(); @Override public void onCreate(Bundle aBundle) { super.onCreate(aBundle); //Calling the AsyncTask class to start to execute. asyncTask.execute(a.targetServer); //Creating a TextView. TextView displayUI = asyncTask.dataDisplay; displayUI = new TextView(this); this.setContentView(tTextView); } } </code></pre> <p>This is the AsyncTask class</p> <pre><code>public class AasyncTask extends AsyncTask&lt;String, Void, String&gt; { TextView dataDisplay; //store the data String soapAction = "http://sample.com"; //SOAPAction header line. String targetServer = "https://sampletargeturl.com"; //Target Server. //SOAP Request. String soapRequest = "&lt;sample XML request&gt;"; @Override protected String doInBackground(String... string) { String responseStorage = null; //storage of the response try { //Uses URL and HttpURLConnection for server connection. URL targetURL = new URL(targetServer); HttpURLConnection httpCon = (HttpURLConnection) targetURL.openConnection(); httpCon.setDoOutput(true); httpCon.setDoInput(true); httpCon.setUseCaches(false); httpCon.setChunkedStreamingMode(0); //properties of SOAPAction header httpCon.addRequestProperty("SOAPAction", soapAction); httpCon.addRequestProperty("Content-Type", "text/xml; charset=utf-8"); httpCon.addRequestProperty("Content-Length", "" + soapRequest.length()); httpCon.setRequestMethod(HttpPost.METHOD_NAME); //sending request to the server. OutputStream outputStream = httpCon.getOutputStream(); Writer writer = new OutputStreamWriter(outputStream); writer.write(soapRequest); writer.flush(); writer.close(); //getting the response from the server InputStream inputStream = httpCon.getInputStream(); BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream)); ByteArrayBuffer byteArrayBuffer = new ByteArrayBuffer(50); int intResponse = httpCon.getResponseCode(); while ((intResponse = bufferedReader.read()) != -1) { byteArrayBuffer.append(intResponse); } responseStorage = new String(byteArrayBuffer.toByteArray()); } catch (Exception aException) { responseStorage = aException.getMessage(); } return responseStorage; } protected void onPostExecute(String result) { aTextView.setText(result); } } </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.
