        final Switch o = (Switch)findViewById(R.id.obamaswitch);
    if (o.isChecked()){
        o.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                ImageView p = (ImageView)findViewById(R.id.obamahere);
                p.???;
            }
        });

如果你想改变图片资源 onChecked switch 那么你可以这样做

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

如果你想在点击 swith 时设置 ImageResource，那么就这样做

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