ListView is not displayed correctly when swiping

I have a generic abstract class that inherits from BaseAdapter and which I use to load ListView (s) from a ArrayList of any objects. The class works well and being abstract forces me to implement the onEntrada method that is the one I use for each object and the new view that is filled in, that is, the mold layout to be filled in.

So far, the problem is that when I slide my finger on the tablet that I have for the tests the letters of the TextViews if they overwrite seeing the fatal thing, until I loose and return everything to its place.

I thought the problem came because the ListView calls the getView function continuously and reloads all the data, so I tried something I found around here, to create a static ViewHolder class with the Views equal to the ones I need per row and go checking that it has not been filled, but the result is the same. You see the fatal thing. I do not know if it's a problem with the Android version, the size of the Tablet, the performance (the latter misses me, it's a Samsung Galaxy of the last and it's going very well). If someone has happened or better know the solution to see if you can throw a cable. I leave the class I use as Adpater.

public abstract class Lista_adaptador extends BaseAdapter {

    private ArrayList<?> entradas;
    private int R_layout_IdView;

    public Context getContexto() {
        return contexto;
    }

    private Context contexto;

    public Lista_adaptador(Context contexto, int R_layout_IdView, ArrayList<?> entradas) {
        super();
        this.contexto = contexto;
        this.entradas = entradas;
        this.R_layout_IdView = R_layout_IdView;
    }

    @Override
    public View getView(int posicion, View view, ViewGroup pariente)
    {View v = view;
        if (v == null) {
            LayoutInflater vi = LayoutInflater.from(contexto);
            v = vi.inflate(R_layout_IdView, null);
        }
        else
        {

        }
        onEntrada(entradas.get(posicion), v);
        return v;

    }

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

    @Override
    public Object getItem(int posicion) {
        return entradas.get(posicion);
    }

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

    /**
     * Devuelve cada una de las entradas con cada una de las vistas a la que debe de ser asociada
     *
     * @param entrada La entrada que será la asociada a la view. La entrada es del tipo del paquete/handler
     * @param view    View particular que contendrá los datos del paquete/handler
     */
    public abstract void onEntrada(Object entrada, View view);

}

Thanks Einer probe v = vi.inflate (R_layout_IdView, relative, false); and the thing remains the same. I attached an image of how it looks.

The class is abstract as I say you can use any other class to load your ListView, just have an ArrayList of any objects and implement the OnEntry () Example:

Aggregated list.setAdapter (new Adapter_list (this, R.layout.linea_note, Aggregated data) {

        @Override
        public void onEntrada(Object entrada, View view) {
             //Aquí se rellenan los views de la view de entrada.
         }

One of the xml I use to inflate the cells in the lists is this:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tv_refLineaNota"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Referencia"
        android:textSize="18sp" />

    <TextView
        android:id="@+id/tv_nombreLineaNota"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Nombre de Linea de Nota"
        android:textSize="18sp" />

</LinearLayout>

<TextView
    android:id="@+id/tv_cantidadlineanota"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_weight="0"
    android:gravity="center"
    android:paddingRight="5dp"
    android:text="Cantidad"
    android:textSize="18sp" />

<TextView
    android:id="@+id/tv_tipounidadLineaNota"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="right"
    android:layout_weight="0"
    android:gravity="left|center"
    android:paddingRight="5dp"
    android:paddingTop="2dp"
    android:text="Kg" />
