Question: I want to implement CustomArrayAdapter and following is the constructor I have written for my custom adapter

```
public CustomUsersAdapter(Context context, ArrayList<User> users) {
        super(context, 0, users);
     }

```

The second argument in the super call The resource ID for a layout file containing a TextView to use when instantiating views. I dont know which resource ID is being referred here. Can anyone please explain in detail which resource ID is being referred here.

My overridden getView method is as follows :-

```
 @Override
     public View getView(int position, View convertView, ViewGroup parent) {
        // Get the data item for this position
        User user = getItem(position);    
        // Check if an existing view is being reused, otherwise inflate the view
        if (convertView == null) {
           convertView = LayoutInflater.from(getContext()).inflate(R.layout.item_user, parent, false);
        }
        // Lookup view for data population
        TextView tvName = (TextView) convertView.findViewById(R.id.tvName);
        TextView tvHome = (TextView) convertView.findViewById(R.id.tvHometown);
        // Populate the data into the template view using the data object
        tvName.setText(user.name);
        tvHome.setText(user.hometown);
        // Return the completed view to render on screen
        return convertView;
    }

```

Answer: 
**Try this way,hope this will help you to solve your problem.**

```
class CustomUsersAdapter extends BaseAdapter {

    private Context context;
    pArrayList<User> users;

    public CustomUsersAdapter(Context context,ArrayList<User> users) {
        this.context = context;
        this.users = users;
    }

    public class ViewHolder {
        TextView tvName;
        TextView tvHometown;
    }

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

    @Override
    public Object getItem(int position) {
        return users.get(position);
    }

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

    public View getView(final int position, View view, ViewGroup parent) {
        final ViewHolder holder;
        if (view == null) {
            holder = new ViewHolder();
            view = LayoutInflater.from(context).inflate(R.layout.item_user, null);
            holder.tvName = (TextView) view.findViewById(R.id.tvHometown);
            holder.tvHometown = (TextView) view.findViewById(R.id.tvHometown);
            view.setTag(holder);
        } else {
            holder = (ViewHolder) view.getTag();
        }
        holder.tvName.setText(users.get(position).name);
        holder.tvHometown.setText(users.get(position).hometown);
        return view;
    }
}

```
I'm not quite sure what you're going to use your `ArrayAdapter` for, but one reason for using an `ArrayAdapter` is to display a `listView` of a layout depending on the array.

Here is an example of what the constructor should look like

```
public CustomListAdapter() {
    super(Activity_Main.class, R.layout.listview_item, array);
}

```

Here is what could be in your listview\_item :

```
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="name"
        android:id="@+id/name" />

</LinearLayout>

```

Basically, the `CustomListAdapter` will generate X number of `listview_item` layouts height wise in a `ListView`, where X is the size of `array`.

Hope this helps.
