Question

I am trying to call an AsyncTask from a spinner (depending on the option chosen will send something or other), but I get problems with a method I have in AsyncTask class and will not let me run it properly.

I’m getting the following error message:

The method setOnResultsListener(OnTaskCompleted) in the type Conexion is not applicable for the arguments (new AdapterView.OnItemSelectedListener(){})

Answer 1

In your AsyncTask class, change this

public void setOnResultsListener(OnTaskCompleted listener) {
    this.listener = listener;
}

to this:

public Conexion(OnTaskCompleted listener) {
    this.listener = listener;
}

And in your MainActivity, change this

Conexion conexion = new Conexion();
conexion.setOnResultsListener(this);
conexion.execute("tipo");

to this:

new Conexion(MainActivity.this).execute("tipo");
