I have tried many options including creating a baseAdapter for my spinner arraylist but nothing seems to work. Here is my custom arrayadapter where I think is the problem but I don't know:

public class SpinnerArrayAdapter extends ArrayAdapter<ContactsData> {
...
public View getCustomView(int position, ViewGroup parent, View convertView){

    View row = convertView;
    ContactsHolder holder = null;

    if(row == null){
        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
        row = inflater.inflate(R.layout.row, parent, false);

        holder = new ContactsHolder();

        holder.name = (TextView)row.findViewById(R.id.contactName);
        holder.number = (TextView)row.findViewById(R.id.contactPhone);

        row.setTag(holder);
    }else{
        holder = (ContactsHolder)row.getTag();
    }

    ContactsData contactsData = data.get(position);

    holder.name.setText(contactsData.name);
    holder.number.setText(contactsData.number);
    return row;
}

static class ContactsHolder{
    TextView name;
    TextView number;
}

And here is my layout row.xml file:

   <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content">

    <TextView
        android:id="@+id/contactName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/contactPhone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

Thanks in advance.

initializing arrayadapter in mainactivity.java

ArrayList<ContactsData> contacts_data = new ArrayList<>();

    contacts_data.add(new ContactsData("lol", "2"));

    SpinnerArrayAdapter mAdapter = new SpinnerArrayAdapter(MainActivity.this, R.layout.row, contacts_data);

    mAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    mySpinner.setAdapter(mAdapter);

how do you initialize your array adapter? – injecteer Apr 27 '15 at 10:03 — injecteer, Apr 27 '15 at 10:03
can you post your Adapter's constructor ? – Blackbelt Apr 27 '15 at 10:03 — Blackbelt, Apr 27 '15 at 10:03

you need to add the id of the TextView you would like to use

E.g.

SpinnerArrayAdapter mAdapter = new SpinnerArrayAdapter(MainActivity.this, R.layout.row, R.id. contactName, contacts_data);

and off course

public class SpinnerArrayAdapter extends ArrayAdapter<ContactsData> {
   public SpinnerArrayAdapter(Context c, int layoutId, int textViewId, ArrayList<ContactsData> data) {
        super(c, layoutId, textViewId, data);
        // other stuff
  } 
}

this is just a workaround for the super class, since you are taking care of the visualisation in your getView

is it possible to use 2 different textviews? – svenvdz Apr 27 '15 at 10:13
it is. You need the id just as workaround for the super class. The rest looks correct to me – Blackbelt Apr 27 '15 at 10:18

your layout file should contain only one textview and it cannot be wrapped under any layout like the below

<?xml version="1.0" encoding="utf-8"?>
        <TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        // other attributes of the TextView
        />
