Android custom array adapter getView is not called

Question

this is my adapter, the getView method is not called even if the array list having elements

public class CarrierSammuryAdapter extends ArrayAdapter<CarrierSummary> {

private final Activity context;
private final ArrayList<CarrierSummary> ite;
private final int lay;


public CarrierSammuryAdapter(Activity context, ArrayList<CarrierSummary> menuLinkList,int layout) {
    super(context,layout );
    this.context = context;
    this.ite = menuLinkList;
    this.lay=layout;




}
// static to save the reference to the outer class and to avoid access to
        // any members of the containing class

    static class ViewHolder {
    public  TextView customer;
    public  TextView attempts;
    public    TextView successful;
    public    TextView  minutes;
    public    TextView ASR;
    public    TextView ACD;
    public    TextView NER;
    public    TextView PDD;

    }
    @Override
    public int getCount () {
        return ite.size();
    }

    @Override
    public long getItemId (int position) {
        return position;
    }

    @Override
    public CarrierSummary getItem (int position) {
        return ite.get(position);
    }

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // ViewHolder will buffer the assess to the individual fields of the row layout

            final ViewHolder holder;

            // Recycle existing view if passed as parameter
                    // This will save memory and time on Android
                    // This only works if the base layout for all classes are the same
                    View rowView = convertView;
                    if (rowView == null) {
            LayoutInflater inflater =  context.getLayoutInflater();//this gives error !!
            rowView=inflater.inflate(R.layout.carriersumamry_item,parent,false);

             holder = new ViewHolder();

             holder.customer=(TextView)rowView.findViewById(R.id.customer);
              holder.attempts=(TextView)rowView.findViewById(R.id.attempts);
              holder.successful=(TextView)rowView.findViewById(R.id.successful);
              holder.minutes=(TextView)rowView.findViewById(R.id.minutes);
              holder.ASR=(TextView)rowView.findViewById(R.id.asr);
              holder.ACD=(TextView)rowView.findViewById(R.id.acd);
              holder.NER=(TextView)rowView.findViewById(R.id.ner);
              holder.PDD=(TextView)rowView.findViewById(R.id.pdd);
            // ViewResizing.setListRowTextResizing(rowView, context);

             rowView.setTag(holder);
                    } else {
                        holder = (ViewHolder) rowView.getTag();
                    }

                      holder.customer.setText(ite.get(position).getCustomer());
                       holder.attempts.setText(ite.get(position).getAttempts());
                       holder.successful.setText(ite.get(position).getSuccessful());
                       holder.minutes.setText(ite.get(position).getMinutes());
                       holder.ASR.setText(ite.get(position).getASR());
                       holder.ACD.setText(ite.get(position).getACD());
                       holder.NER.setText(ite.get(position).getNER());
                       holder.PDD.setText(ite.get(position).getPDD());
            return rowView;


}

}

and this is how i called it

         carrierSummaryList =(ListView)findViewById(R.id.carrierSummary_listview);
        CarrierSammuryAdapter adapter = new CarrierSammuryAdapter(CarrierSummaryActivity.this,  carriersam,R.layout.carriersumamry_item);
        carrierSummaryList.setAdapter(adapter);

I search a lot to solve this issue but no solution, getView method is never called.

this is my XML

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
   android:layout_height="wrap_content"
  android:orientation="horizontal"

Answer 1

The problem was in my drawerLayout, i put the listView into RelativeLayout but when i change to LinearLayout its working, this is the code

  <android.support.v4.widget.DrawerLayout

Answer 2

there are two mistakes.. first is change Activity to Contex in constructor secondly change

rowView=inflater.inflate(R.layout.single_row,parent,false);

Hope this will help you

Answer 3

/**
 * Constructor
 *
 * @param context The current context.
 * @param resource The resource ID for a layout file containing a TextView to use when
 *                 instantiating views.
 */
public ArrayAdapter(Context context, int resource) {
    init(context, resource, 0, new ArrayList<T>());
}

while you are doing super(context,layout) , this is the constructor that gets called. So adapter data is set to empty list.

Like derek said, Instead you should use super(context,layout,menuLinkList);

/**
     * Constructor
     *
     * @param context The current context.
     * @param resource The resource ID for a layout file containing a TextView to use when
     *                 instantiating views.
     * @param objects The objects to represent in the ListView.
     */
    public ArrayAdapter(Context context, int resource, List<T> objects) {
        init(context, resource, 0, objects);
    }

Answer 4

I had this exact same problem, to solve it, I simply changed the ArrayAdapter to BaseAdapter, implemented the overriden methods and it worked.

And as khuskal said, you should always use Context instead of Activity.
