Question

I am trying to display ListView.

I have created one activity , in onCreate() method I am launching one AsyncTask and in onPostExecute() method I am trying display ListView in that .

but listView object receiving null..

Below is the code snippet.

 protected void onPostExecute(KpiResponseObject kpiReportResponse) {
     ListView listView;
     listView = (ListView) findViewById(R.id.list_view);
}

Here I’am receiving null in listView object.

I am suspecting this is the context problem , but not able figure out what exactly it is.

Are you sure you have setContentView in your onCreate and then have a ListView list_view defined in XML?
