Android PopupWindow and SeekBar listener not responding

Question

Does anyone know why my seekbar listener is not picking up any data from the seekbar?? i have it all setup and working but it isnt updating the textviews, i think it has something to do with the popup window using a different activity layout to the activity it sits inside

public class Environment extends Activity implements OnSeekBarChangeListener
{

private ImageButton lockButton;


SeekBar bar;
TextView textProgress, textAction;
private PopupWindow pwindo;


@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.setup_environment);

    lockButton = (ImageButton) findViewById(R.id.lock);
    lockButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {
            initiatePopupWindow();

        }
    });

}


private void initiatePopupWindow() {
    try {
        LayoutInflater inflater = (LayoutInflater) Environment.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.annotation,
                (ViewGroup) findViewById(R.id.popup_element));
        pwindo = new PopupWindow(layout, 1000, 1200, true);
        pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);

        bar = (SeekBar)findViewById(R.id.seekBar1); // make seekbar object
        bar.setOnSeekBarChangeListener(this);
        textProgress = (TextView)findViewById(R.id.textViewProgress);

        textAction = (TextView)findViewById(R.id.textViewAction);

    } catch (Exception e) {
        e.printStackTrace();
    }
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,
                              boolean fromUser) {
    // TODO Auto-generated method stub

    textProgress.setText("The value is: "+progress);

    textAction.setText("changing");
}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
    textAction.setText("starting to track touch");

}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
    seekBar.setSecondaryProgress(seekBar.getProgress());
    textAction.setText("ended tracking touch");
}

} Whenever i use the slider it should update with the int value 0-100 depending on where the slider is, it works if i create an activity and use it straight away, but when i put it in a popupwindow it doesnt do anything??

Try this, you should be initializing your Seekbar etc by the views from the layout. Simply doing findViewById searches for the views in the activity

private void initiatePopupWindow() {
    try {
        LayoutInflater inflater = (LayoutInflater) Environment.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.annotation,
                (ViewGroup) findViewById(R.id.popup_element));
        pwindo = new PopupWindow(layout, 1000, 1200, true);
        pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);

        bar = (SeekBar)layout.findViewById(R.id.seekBar1); // make seekbar object
        bar.setOnSeekBarChangeListener(this);
        textProgress = (TextView)layout.findViewById(R.id.textViewProgress);

        textAction = (TextView)layout.findViewById(R.id.textViewAction);

    } catch (Exception e) {
        e.printStackTrace();
    }
}
