cómo actualizar el texto de la vista de texto según el estado de una casilla de verificación en la vista de lista
Aquí está mi ListViewAdapter personalizado

db.open();
checkedItems= new boolean[list.size()];
ckboxTextAdd=new String[list.size()];
for(int i=0;i<list.size();i++)
{
checkedItems[i]=false;

}

private class Viewholder extends Activity

Ahora, lo que quiero actualizar es mi vista de texto en el instante en que se hace clic en la casilla de verificación en la vista de lista, pero hasta ahora no funciona como se desea, pero cuando me desplazo hacia abajo y miro el elemento marcado, se actualiza TextView
Por favor ayudame Gracias de antemano
