Accessing view from SelectedListener

Hi:

I'm working through the "Hello View" tutorial on the developer.android website, and am looking for a best practice on how to do something.

My layout has a Spinner and an ImageView. When I select something for the spinner, I want to change the image in the ImageView.

So, in the Activity onCreate, I establish the listener for a spinner with spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

Now, within the listener, I need to "get a handle" for the ImageView.
As a crude solution, I successfully tried to

1. Create a public attribute in the Activity with:
public static Test2Activity act;

2. In the Activity onCreate, set it as:
act = this;

3. In the listener did:
ImageView imageView = (ImageView) Test2Activity.act.findViewById(R.id.birdimage);

4. so I could then change image with:
imageView.setImageResource(R.drawable.harpy);

Seems there's a better way! Any suggestions? Thanks!

Thanks for helping out!

I tried that (first), but get

The method findViewById(int) is undefined for the type MyOnItemSelectedListener

(Which is what led me to my known, ah, circumstantial hack...)

Following is the whole piece of code in the listener. I know I'm missing something obvious, but just don't see it. Note the working piece is commented out.

package com.tests.test2;

import android.view.View;
import android.widget.AdapterView;
import android.widget.ImageView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemSelectedListener;

public class MyOnItemSelectedListener implements OnItemSelectedListener {

public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {

String selectedBird = parent.getItemAtPosition(pos).toString();

//ImageView imageView = (ImageView) Test2Activity.act.findViewById(R.id.birdimage);

ImageView imageView = findViewById(R.id.birdimage);
gives error The method findViewById(int) is undefined for the type MyOnItemSelectedListener

if (selectedBird.equals("Harpy Eagle")) {
imageView.setImageResource(R.drawable.harpy);
} else if (selectedBird.equals("Osprey")) {
imageView.setImageResource(R.drawable.osprey);
} else if (selectedBird.equals("Great Horned Owl")) {
imageView.setImageResource(R.drawable.greathorned);
} else {
Toast.makeText(parent.getContext(), selectedBird + " Not Defined", Toast.LENGTH_LONG).show();
}
}


public void onNothingSelected(AdapterView parent) {
// Do nothing.
}
}

 

OK... I'm thinking that my listener needs to extend my activity, and be

public class MyOnItemSelectedListener extends Test2Activity implements OnItemSelectedListener

Doh!
