android: Error when use setAdapter in Fragment to call Activity

Question

I'm doing the application fetches the data from the database and displayed in Listview

and Must be all the Classes be a Fragment so I can put it in tabs

The error is:

  this.getlistdata.setAdapter(new GetAllSongs(jsonArray,this));

Exactly ... (jsonArray,this)

Full code.

public class GetListData extends Fragment
{
    ListView getlistdata;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        this.getActivity().setContentView(R.layout.activity_main2);

        this.getlistdata =  (ListView)this.getActivity().findViewById(R.id.listgetdata);

        new GetAllCustomerTask().execute(new ApiConnector());
    }

    public  void setListAdapter (JSONArray jsonArray)
    {
        this.getlistdata.setAdapter(new GetAllSongs(jsonArray,this));
    }

    private class GetAllCustomerTask extends AsyncTask<ApiConnector,Long,JSONArray>
    {
        @Override
        protected JSONArray doInBackground(ApiConnector... params)
        {
            return params[0].GetAllCustomers();
        }

        @Override
        protected void onPostExecute(JSONArray jsonArray)
        {
            setListAdapter(jsonArray);
        }
    }

The error is ::

can't cast Fragment To Activity

How can I fix it?

Can you post the full error? `this.getlistdata.setAdapter(new GetAllSongs(jsonArray,this));` doesn't look like an error message, and neither does `this.getlistdata.setAdapter(new GetAllSongs(jsonArray,this));` — WhiteViking, Sep 16 '15 at 21:28

GetAllSongs() is expecting an Activity as the second argument, but you are passing a Fragment.

The following statement should eliminate the exception:

this.getlistdata.setAdapter(new GetAllSongs(jsonArray, getActivity()))
