    <p>im pretty new In Android App development, I need some help. Im creating this simple dictionary application that prompts the user to enter a word and after a button press it will take that word to the internet, probably wikipedia.org and return that information to the User. I used XML to develop the app textfield and button. And created a piece of text (ansa) which will be set to whatever the answer is using the OnClickListener, I do not want to set up a webview I just want the text to be set to the dictionary answer. Here's what i have been able to do so far. There is this class to get data from google.</p> <pre><code>public class GetMethod { public String getInternetData() throws Exception{ BufferedReader in = null; String data = null; try{ HttpClient client = new DefaultHttpClient(); URI website = new URI("http://www.google.com"); HttpGet request = new HttpGet(); request.setURI(website); HttpResponse response = client.execute(request); in = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); StringBuffer sb = new StringBuffer(""); String l = ""; String nl = System.getProperty("line.separator"); while((l = in.readLine()) !=null){ sb.append(l + nl); } in.close(); data = sb.toString(); return data; }finally{ if (in !=null){ try{ in.close(); return data; }catch(Exception e){ e.printStackTrace(); } } } } </code></pre> <p>And Another class where the XML is implemented</p> <pre><code>public class Dictionary extends Activity { TextView ansa; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.dictionary); Button Search = (Button) findViewById(R.id.search); ansa = (TextView) findViewById(R.id.ansa); final GetMethod test = new GetMethod(); Search.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub String returned; try { returned = test.getInternetData(); ansa.setText(returned); } catch (Exception e) { ansa.setText("Failed"); // TODO Auto-generated catch block e.printStackTrace(); } } }); } </code></pre> <p>} When it executes I get the whole website's HTML</p> <p>So I need help on how to take the user's word to the wiki website, and get only the text of the ansa, probably parse and store it to some string. Thank You Alot.</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.
