I have some classes that used to inherit from ListActivity directly. Everything worked. Now I am inheriting from BaseListActivity which inherits from ListActivity.

Here is BaseListActivity:

public class BaseListActivity extends ListActivity 
{
    @Override
    public void setContentView(int layoutResID) {
        super.setContentView(layoutResID);      
    {
        Button home_header = (Button)findViewById(R.id.home_header);
        Button questions_header = (Button)findViewById(R.id.questions_header);

        home_header.setOnClickListener(new Button.OnClickListener() 
        {  
            public void onClick(View v) 
            {                   
              Intent myIntent = new Intent( BaseListActivity.this , ProblemioActivity.class);
              BaseListActivity.this.startActivity(myIntent);
            }
        });                 

        questions_header.setOnClickListener(new Button.OnClickListener() 
        {  
            public void onClick(View v) 
            {                   
              Intent myIntent = new Intent( BaseListActivity.this , MyQuestionsActivity.class);
              BaseListActivity.this.startActivity(myIntent);
            }
        });         
}
}

It basically adds a header to the page. But now none of the lists get rendered and there are no exceptions.

Any idea what else I had to do to make it work?

Here is how I changed my original layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:orientation="vertical" >    


<include android:id="@+id/header"
         layout="@layout/header"
         android:layout_height="wrap_content"
         android:layout_width="fill_parent"/>    


<TextView
    android:id="@+id/question_label"    
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Loading your questions..."
    />     

    <ListView
    android:id="@android:id/list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@+id/label"
        android:textSize="20px" >        
    </ListView>

Here is my onCreate

public class MyQuestionsActivity extends BaseListActivity
{
    ArrayAdapter<Question> adapter;     

    ArrayList<Question> questions = new ArrayList <Question>( );        

@Override
    public void onCreate(Bundle savedInstanceState) 
{   
    super.onCreate(savedInstanceState);

    setContentView(R.layout.users_questions);

    Question q = new Question ();
    q.setQuestion( "" );

    questions.add(q);       

    adapter = new ArrayAdapter<Question>(this, R.layout.user_question_list, questions);

Right now I have this in my BaseListActivity

@Override
    public void setContentView(int layoutResID) {
        super.setContentView(layoutResID);      
    {

I just tried this:

public class BaseListActivity extends ListActivity 
{
    @Override
    public void setContentView(int layoutResID) {
        super.setContentView(layoutResID);      
    {
        setListAdapter(this.getListAdapter());

but it didn’t quite work 🙁
