If you want to change image Resource onChecked switch then you can do this 

ImageView image = (ImageView)findViewById(R.id.obamahere);
   final Switch o = (Switch)findViewById(R.id.obamaswitch);
if (o.isChecked()){
image.setImageResource(R.drawble.icon);
   }

and if you want to setImageResource when click on swith then do this

new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                   image.setImageResource(R.drawble.icon);
                }else{
                    do your work...
                }
            }
        });

Did you mean setting image programmatically, if yes then you can use setImageResource() property of imageview.
In your case the code will become as 

p.setImageResource(R.drawable.<yourimagename>)

In case you wish to set image from file the you can do as follows 

File imgFile = new  File("/sdcard/Images/test_image.jpg");

if(imgFile.exists()){
    Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
    p.setImageBitmap(myBitmap);
}

Hope this will meet your needs
