Add buttons to a listactivity
From http://developer.android.com/reference/android/app/ListActivity.html:
“ListActivity has a default layout that consists of a single, full-screen list in the center of the screen. However, if you desire, you can customize the screen layout by setting your own view layout with setContentView() in onCreate(). To do this, your own view MUST contain a ListView object with the id "@android:id/list"”
EDIT: here is an example:
The ListActivity may be created like this:
public class ListViewTest extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String[] values = {"One", "Two", "Three"}; setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, values)); setContentView(R.layout.main); } }
The main.xml
layout is as follows:
<?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:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:id="@android:id/list"></ListView> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="Test button" android:id="@+id/TestButton"></Button> </LinearLayout>

I have a layout for a ListActivity. To modify the list I have used menu-options. But to remove a couple of "clicks" on the screen I'd like to add two buttons in the button of the screen that is always visible and not affected if the list is scrolled.
My problem is that I don't know how to add these buttons. I have tried a couple of solutions but the best I managed either the list or the buttons disapears from the layout. Seems that I can't get both buttons and list visible at the same time.
So my question is how to create a layout where I can have both buttons and the list?
Thanks in advance Roland

Roland over 13 yearsI have a custom layout, but I can't get it to show anything else but the listview itself, or the other component, but not both. So I'd like to see an exampel that actually works.
