    <p>I am new to android/java and trying to learn by typing code from <a href="http://www.androidhive.info/2011/11/android-xml-parsing-tutorial/" rel="nofollow">tutorials</a>. I'm trying to see if I can make a FAQs android module. Could someone show me how to display only the list of questions and when you click on a question, correspond question and answer display on the next activity? It's currently displaying both question and answer for the both activities. </p> <p>Hope my question makes sense. please kindly ask and I will explain as best as I can.</p> <p>Thank you very much! </p> <p>faq_list.xml</p> <p> </p> <pre><code>&lt;item&gt; &lt;id&gt;1&lt;/id&gt; &lt;question&gt;Whats my phone number?&lt;/question&gt; &lt;answer&gt;my phone number here&lt;/answer&gt; &lt;/item&gt; &lt;item&gt; &lt;id&gt;2&lt;/id&gt; &lt;question&gt;Whats my fax number?&lt;/question&gt; &lt;answer&gt;my fax number here&lt;/answer&gt; &lt;/item&gt; &lt;item&gt; &lt;id&gt;3&lt;/id&gt; &lt;question&gt;What is my mailing address?&lt;/question&gt; &lt;answer&gt;my address here&lt;/answer&gt; &lt;/item&gt; </code></pre> <p></p> <p>faqs_questions.xml</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical"&gt; &lt;!-- qnestion --&gt; &lt;TextView android:id="@+id/question" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#000" android:textSize="14sp" android:layout_marginBottom="10dip" android:layout_marginTop="10dip" android:layout_weight="1" android:paddingLeft="5sp" /&gt; &lt;!-- answer --&gt; &lt;TextView android:id="@+id/answer" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#000" android:textSize="14sp" android:layout_marginBottom="10dip" android:layout_marginTop="10dip" android:layout_weight="2" android:paddingLeft="5sp"&gt; &lt;/TextView&gt; &lt;/LinearLayout&gt; </code></pre> <p>faqs_answers.xml</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:background="#fff" android:layout_width="match_parent" android:layout_height="match_parent"&gt; &lt;TextView android:id="@+id/question_label" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="14dip" android:textStyle="bold" android:textColor="#000" android:paddingLeft="5sp" /&gt; &lt;TextView android:id="@+id/answer_label" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="14dip" android:textColor="#000" android:paddingLeft="5sp" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>FaqsQuestionsActivity.java</p> <pre><code> public class FaqsQuestionsActivity extends ListActivity { static final String URL = "http://myweb.com/faq_list.xml"; // XML node keys static final String KEY_ITEM = "item"; // parent node static final String KEY_ID = "id"; static final String KEY_QUESTION = "question"; static final String KEY_ANSWER = "answer"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.faqs_questions); ArrayList&lt;HashMap&lt;String, String&gt;&gt; menuItems = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); XMLParser parser = new XMLParser(); String xml = parser.getXmlFromUrl(URL); // getting XML Document doc = parser.getDomElement(xml); // getting DOM element NodeList nl = doc.getElementsByTagName(KEY_ITEM); for (int i = 0; i &lt; nl.getLength(); i++) { HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); Element e = (Element) nl.item(i); map.put(KEY_ID, parser.getValue(e, KEY_ID)); map.put(KEY_QUESTION, parser.getValue(e, KEY_QUESTION )); map.put(KEY_ANSWER, parser.getValue(e, KEY_ANSWER)); menuItems.add(map); } ListAdapter adapter = new SimpleAdapter(this, menuItems, R.layout.faqs_question_list, new String[] { KEY_QUESTION, KEY_ANSWER }, new int[] {R.id.question, R.id.answer}); setListAdapter(adapter); ListView lv = getListView(); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { String question = ((TextView) view.findViewById(R.id.question)).getText().toString(); String answer = ((TextView) view.findViewById(R.id.answer)).getText().toString(); Intent in = new Intent(getApplicationContext(), FaqsAnswersActivity.class); in.putExtra(KEY_QUESTION, question); in.putExtra(KEY_ANSWER, answer); startActivity(in); } }); } } </code></pre> <p>FaqsAnswersActivity.java</p> <pre><code>public class FaqsAnswersActivity extends Activity { // XML node keys static final String KEY_QUESTION = "question"; static final String KEY_ANSWER = "answer"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.faqs_answers); // getting intent data Intent in = getIntent(); // Get XML values from previous intent String question = in.getStringExtra(KEY_QUESTION); String answer = in.getStringExtra(KEY_ANSWER); // Displaying all values on the screen TextView lblQuestion = (TextView) findViewById(R.id.question_label); TextView lblAnswer = (TextView) findViewById(R.id.answer_label); lblQuestion.setText(question); lblAnswer.setText(answer); } } </code></pre>

Guidance
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.
