    <p>I am working on an app that works similar to the default text messaging app on all Android phones. My problem is selecting more than one user to send an SMS message to. What I have done so far is stored my contacts as listview items with check boxes. Now I just need to get the phone numbers from the selected contacts.</p> <p>So what I am having trouble on doing. 1) Pulling a phone number from the contacts displayed in my listview 2)displaying that number in a textview in a new activity</p> <p>Sorry if my code is difficult to understand, please ask if you need clerification.</p> <p>This is the XML in which the listview is shown, called contact_manager.xml: </p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;ListView android:id="@+id/contactList" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1" /&gt; &lt;Button android:id="@+id/showInvisible" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/showInvisible" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>This is my Activity that calls everything together.</p> <pre><code>public final class ContactManager extends Activity { public static final String TAG = "ContactManager"; private ListView mContactList; private boolean mShowInvisible; private Button mShowInvisibleControl; /** * Called when the activity is first created.

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.
