Below are the errors that appear in Logcat when starting the application in the emulator. The error message displayed on the screen is "Unfortunately, Contacts Manager has stopped."

I believe the error is in this part:

public View getView(int position, View convertView, ViewGroup parent) 
{
    // Recupera a pessoa da posição atual
    Contact p = list.get(position);

    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.contact_table, null);

    // Atualiza o valor do TextView
    TextView firstname = (TextView) view.findViewById(R.id.showname);
    firstname.setText(p.firstname);

    return view;
}

Anyway, the codes that contain Adapters, manifest and xml referring to Textview with error are attached:

    {
        this.context = context;
        this.list = list;
    }

    public int getCount() 
    {
        return list.size();
    }

    public Object getItem(int position) 
    {
        return list.get(position);
    }

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

    public View getView(int position, View convertView, ViewGroup parent) 
    {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.contact_table, null);

        // Atualiza o valor do TextView
        TextView firstname = (TextView) view.findViewById(R.id.showname);
        firstname.setText(p.firstname);

        return view;
    }

}

To make it clear, the idea of the project is a contact schedule synchronized with that of Android. The excerpt in which the error appeared, refers to the update of the contact’s name and last name in a Listview.

Then I will complete the update of the photo as well. If someone already knows how to do this, or if there is a topic with a solution, I would appreciate.

EDIT.:

Follow the Userrecord code (where the Useritemadapter comes from):

package br.com.contactsmanager;

public class UserRecord 
    {
    public String firstname;

    public UserRecord(String firstname) 
    {
        this.firstname = firstname;
    }
}

Answer 1

Unfortunately the part of the log that could actually reveal where the error is got truncated:

Caused by: java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.TextView
    at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:379)
    ... 38 more

But by the exception in itself, you can already see that a LinearLayout is being used where one expects TextView, within the class ArrayAdapter.

Who creates the UserItemAdapter? The second parameter passed to him (textViewResourceId) is that correct? Second that documentation when creating a ArrayAdapter with three parameters, as you did, the second should be the layout ID, not the textView - and how you named the parameter textViewResourceId I imagine that maybe he is wrong.

(although this does not explain the error message - it should be the other way around, a ClassCastException of TextView for LinearLayout)

Have you tried using the constructor of 4 parameters of ArrayAdapter? I don’t know if it’ll do the trick, but it’s the best suggestion I can make in front of the current information. If not, try to isolate the code snippet where the exception is occurring (using try...catch, printing in the log, something like that) to make it easier to know where it is.
