In your first Activity when you click on button:
startActivity(new Intent(this, ContactsActivity.class));
Then in your ContactsActivity:
public class ContactsActivity extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.contacts_view);
ListAdapter adapter = createAdapter();
setListAdapter(adapter);
}
/**
* Creates and returns a list adapter for the current list activity
* @return
*/
protected ListAdapter createAdapter()
{
// List with strings of contacts name
contactList = ... someMethod to get your list ...
// Create a simple array adapter (of type string) with the test values
ListAdapter adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, contactList);
return adapter;
}
}
XML file for your ContactsActivity (name it to contacts_view.xml):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView android:id="@android:id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Empty set"
/>
</LinearLayout>
Can use a listActivity
On the button click you need to start new Activity(or ListActivity) that contains list of all contacts.So you need to set onClicklistener then in onClick function you need to write code for starting Activity
On second activity Create a CustomAdapter that will initialised with say List
class Contact
{
private String number;
private String name
}
Thanks.
