drag ImageView inside a WebView

:) I'm adding an ImageView inside a WebView like this :

    void addImv(int in)
{
     imageView.setId(imageID);
     webComp.addView(imageView);

     Bitmap bitmap;
     File sd = Environment.getExternalStorageDirectory();
     if(sd.canRead()){
         bitmap = BitmapFactory.decodeFile(sd.getAbsolutePath() + "/FMS/1/file"+in+".jpg");
         imageView.setImageBitmap(bitmap);
         imageView.setAdjustViewBounds(true);
         imageView.setMaxHeight(150);
         imageView.setAlpha(150);           

         imageView.bringToFront();          
     }
}

The photo is shown in the left top of the screen correctly. Now I have this listener for touches on the imageView 

    OnTouchListener listenTouch = new OnTouchListener()
{
    @Override
    public boolean onTouch(View v, MotionEvent event)
    {   
        return true;
    }

};

which works too. How can i set the position of the imageView? I've tried using imageView.setPadding and imageView.imageView.setLayoutParams but clearly I'm doing something really wrong as it force-closes. The imageView isn't defined in xml layout file. Thank you!

This worked:

 OnTouchListener listenTouch = new OnTouchListener()

{

public boolean onTouch(View v, MotionEvent event)
{   
    imageView.offsetLeftAndRight((int)event.getX()-imageView.getWidth());
    imageView.offsetTopAndBottom((int)event.getY()-imageView.getHeight());
    webComp.invalidate();
    return true;
}

};

Use AbsoluteLayout.LayoutParams setting the correct X and Y co-ordinate or you can also use LinearLayout.LayoutParams OR RelativeLayout.LayoutParams for the purpose.

On how to use:

webComp.addView(imageView, <your params object>);
