<ListView
    android:id="@+id/contests_listView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:layout_below="@+id/header"
    android:focusable="true">
</ListView>

Activity.java

public class Activites_Activity extends CheerfoolznativeActivity {
private ListView contests_listView;
private ProgressBar pgb;
ActivitiesBean bean;
ArrayList<Object> listActivities;
ListAdapter adapter;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_listview);
setHeader("Activites");
contests_listView = (ListView) findViewById(R.id.contests_listView);
pgb = (ProgressBar) findViewById(R.id.contests_progressBar);
listActivities = new ArrayList<Object>();
new FetchActivitesTask().execute();
}
public class FetchActivitesTask extends AsyncTask<Void, Void, Void> {
int i =0;
@Override
protected void onPreExecute() {
//TODO Auto-generated method stub
super.onPreExecute();
pgb.setVisibility(View.VISIBLE);
}
@Override
protected Void doInBackground(Void... params) {
//TODO Auto-generated method stub
String url = "my json URL";
String strResponse = util.makeWebCall(url);
try {
//my json logic here        
}
catch (JSONException e) {
e.printStackTrace();
}
return null;
}
@Override
public void onPostExecute(Void result) {
//TODO Auto-generated method stub
super.onPostExecute(result);
pgb.setVisibility(View.GONE);
displayAdapter();
}
}
public void displayAdapter()
{
adapter = new ListAdapter(this, listActivities);
contests_listView.setAdapter(adapter);
contests_listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long id) {
//Toast.makeText(getApplicationContext(),"Title => "+items.get(position), Toast.LENGTH_SHORT).show();
System.out.println("=========== Click");
bean = (ActivitiesBean) adapter.getItem(position);
Intent in1 = new Intent(Activites_Activity.this, Activity_display.class);
in1.putExtra("ActivityObject", bean);
startActivity(in1);
}
});
}
}

J'utilise aussi cette

contests_listView.setItemsCanFocus(true);
