Android: Ihr Inhalt muss eine ListView haben, deren id-Attribut Android.R.id.list ist

Question

Ich erhalte diesen Laufzeitfehler, und es fällt mir wirklich schwer, der Sache auf den Grund zu gehen: "Ihr Inhalt muss eine ListView haben, deren id-Attribut Android.R.id.list ist".

Hier ist mein Code:

public class ShowAllJobsInArea extends ListActivity{

    Context context;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.show_jobs_in_area);
        context=getApplicationContext();

        String area=Cookie.getAreaSelected();

        final ProgressBar thinger=(ProgressBar) findViewById(R.id.progressBar2);
        TabHost tabHost=(TabHost)findViewById(android.R.id.tabhost);
        tabHost.setup();

        TabSpec spec1=tabHost.newTabSpec("Tab 1");
        spec1.setContent(R.id.tab1);
        spec1.setIndicator("Starting");

        TabSpec spec2=tabHost.newTabSpec("Tab 2");
        spec2.setContent(R.id.tab2);
        spec2.setIndicator("# Days");        

        TabSpec spec3=tabHost.newTabSpec("Tab 3");
        spec3.setContent(R.id.tab3);
        spec3.setIndicator("Rate");

        tabHost.addTab(spec1);
        tabHost.addTab(spec2);
        tabHost.addTab(spec3);

        Handler handler = new Handler() {
             public void handleMessage(Message message) {
                  switch (message.what) {
                      case HttpConnection.DID_START:
                          thinger.setVisibility(View.VISIBLE);
                          break;
                      case HttpConnection.DID_SUCCEED:
                          String response = (String) message.obj;

                          JSONObject object = null;
                          try {
                              object = (JSONObject) new JSONTokener(response).nextValue();

                              for(int i=0;i<object.length();i++){

                              }
                          }catch (JSONException e) {
                              e.printStackTrace();

Ich habe versucht, die id zu Android.id="@Android:id/list" zu ändern, ohne Erfolg - immer noch den gleichen Fehler zu erhalten. Ich dachte, es ist etwas zu tun mit der asynchronen Anforderung, die ich tue... Ich bin jetzt wirklich stecken und hoffe, jemand kann helfen.

Vielen Dank im Voraus,
