Question

I looke at the ListView API
and I saw the method:

addHeaderView(View v)

What I want to do is to have a layout above the list, is this possible ?

I tried doing something like :

  EditText et=new EditText(this);
  et.setLayoutParams(new Gallery.LayoutParams(LayoutParams.FILL_PARENT,     LayoutParams.WRAP_CONTENT));
  et.setInputType(InputType.TYPE_CLASS_TEXT); 
  addHeaderView(et); //makes app crash

I also tried

setContentView(R.layout.tryview);

but it also make the app crash.

Help is very much appreciated!

Edit : The code for this class is:

public class GroupsActivity extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  String your_array_contents[] = {"a","ab","c"};
  setListAdapter(new ArrayAdapter<String>(this, R.layout.groups_layout, your_array_contents));
  EditText et=new EditText(this);
  et.setLayoutParams(new Gallery.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
  et.setInputType(InputType.TYPE_CLASS_TEXT); 

  ListView lv = getListView();
  lv.setTextFilterEnabled(true);
  lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

  lv.setAdapter(new ArrayAdapter<String>(GroupsActivity.this,
    android.R.layout.simple_list_item_multiple_choice, your_array_contents));
    lv.addHeaderView(et); //makes app crash
  lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
      // When clicked, show a toast with the TextView text
     // Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
          //Toast.LENGTH_SHORT).show();
    }
  });
}


}

You simply can’t use View as a Header of ListView.

Because the view which is being passed in has to be inflated.

Look at my answer at Android ListView addHeaderView() nullPointerException for predefined Views for more info.

EDIT:

Look at this tutorial Android ListView and ListActivity – Tutorial .

EDIT 2: This link is broken Android ListActivity with a header or footer
