Only print the first element of Arraylist

Question

My problem right now is to print the various elements that are inside an Arraylist I created. How my app works is as follows::

• I use a Cursor, and I will fetch the table information from the database.
• Then step inside an Arraylist

So far so good, keep the information well inside the Arraylist, the problem here is when the part where I print the elements arrives, just print me the first element.

I have used several solutions of the various questions of the same generic problem, but nothing solves.

I leave down the parts of the code:

    private ArrayList<Bolo> arraylistBolo = new ArrayList<Bolo>();
    private MyListAdapter myAdapter = null;

    private Cursor cursor_bolos;

        super.onResume();

        MyDBHelper dbHelper = new MyDBHelper(context);
        SQLiteDatabase db = dbHelper.getWritableDatabase();


        cursor_bolos = db.rawQuery("SELECT * FROM Bolo", null);


        arraylistBolo.clear();
        if (cursor_bolos != null && cursor_bolos.moveToFirst()) {


            do {
                      arraylistBolo.add(new Bolo(cursor_bolos.getString(1), cursor_bolos.getString(5), cursor_bolos.getString(3), cursor_bolos.getString(2), cursor_bolos.getInt(4), cursor_bolos.getInt(7), cursor_bolos.getString(6), cursor_bolos.getString(8)));
            } while (cursor_bolos.moveToNext());


        }


        myAdapter.notifyDataSetChanged();
        cursor_bolos.close();
        db.close();


    }

XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout_toLine"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/background"
    android:orientation="horizontal"

    >

        <TextView
            android:id="@+id/txtviewData"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="20dp"/>

        <TextView
            android:id="@+id/txtviewestado"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="40dp"

            />



</LinearLayout>

IMPORTANT NOTE:

I’ve used a layout like this, but only print the first element.

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


    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>



    <TextView
        android:id="@android:id/empty"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="lista vazia"

        />

</LinearLayout>

Thank you for your understanding

The problem is in the method getView().

Note that Textview is only filled in when the convertView/v is null. This situation only happens once, when it is of the first item.

Change to:

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

    if (v == null) {
        LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.linhaof_owncakes,parent, false);
    }

    TextView txtData = (TextView) v.findViewById(R.id.txtviewData);
    TextView txtEstado = (TextView) v.findViewById(R.id.txtviewestado);
    txtData.setText(resource.get(position).getDataEntrega());
    int ex = resource.get(position).getEstado();

    if(ex == 0) {
        txtEstado.setText("Pendente");
    }else {
        if(ex == 1) {
            txtEstado.setText("Em preparação");
        }
    }

    return v;
}
