Adding Items to a list view in android

Question

Ok, I completed the tutoriel at this site, http://developer.android.com/resources/tutorials/views/hello-listview.html

My problem is that I want to add items to a list that is nested in a table layout. Like so.

How do I do this??? With my current code, the app stops working when I select the desired page. Assume that myList exists... If I comment out the line setContentView(R.layout.log); the list is shown but without the layout I want.

public class LogActivity extends ListActivity{

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.log);

        ListView lv = getListView();
        lv.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, myList));
        lv.setTextFilterEnabled(true);
    }
}

Answer 1

Just replace the below lines with

ListView lv = getListView();
lv.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, myList));
lv.setTextFilterEnabled(true);

with

ListView lv = (ListView)findViewById(R.id.listView);
ArrayAdapter<String> myarrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, myList);
lv.setAdapter(myarrayAdapter);
lv.setTextFilterEnabled(true);

now just add you new item in mylist and call

myarrayAdapter.notifyDataChanged();

also change the xml file list id and try
