    <p>Here is my android code to send request:</p> <pre><code>// defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(serverUrl); List&lt;NameValuePair&gt; params = new ArrayList&lt;NameValuePair&gt;(); params.add(new BasicNameValuePair("abc", "abc2")); httpPost.setEntity(new UrlEncodedFormEntity(params)); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); InputStream is = null; is = httpEntity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); String json = ""; json = sb.toString(); Log.d("JSON", "JSON is:" + json); </code></pre> <p>and here is my php code to get the request:</p> <pre><code>&lt;?php echo $_POST['abc']; ?&gt; </code></pre> <p>When I run the application, the string <code>json</code> is nothing. I expect to get <code>JSON is:abc2</code><br> Then I change the some code, in android part: </p> <pre><code>HttpPost httpPost = new HttpPost(serverUrl); </code></pre> <p>change to: </p> <pre><code>HttpPost httpPost = new HttpPost(serverUrl + "?abc=abc3"); </code></pre> <p>in php part: </p> <pre><code>&lt;?php echo $_GET['abc']; ?&gt; </code></pre> <p>This time, the string <code>json</code> in logcat is <code>JSON is:abc3</code>. It is correct!!<br> I have tried lots of time, but seems cannot send HttpPost request with params.<br> Any one can help me to find out what wrongs with my code??</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.
