转屏的设置

@Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);

        ImageView header = (ImageView) this.findViewById(R.id.header);

        if ( newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE ) {
             header.setImageResource(R.drawable.header480);
        }
        else if ( newConfig.orientation == Configuration.ORIENTATION_PORTRAIT ) {
            header.setImageResource(R.drawable.header320);

        }
    }

 其实很简单
