在你的第一个活动，当你点击按钮：

In your first Activity when you click on button:

startActivity(new Intent(this, ContactsActivity.class));

然后在您的ContactsActivity：

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;
        }
    }

您ContactsActivity（命名为contacts_view.xml）XML文件：

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>
