Is a man on the next layer 100 [second layer] -- help beautiful women change clothes (2)

The previous article titled "men are the next layer" (Layer 2] -- helping beautiful women change clothes (1) "introduced the use of the ImageSwitcher component and completed the presentation, let's complete the rest of this article.

When you click an image, you can jump to another Activity and upload the serial number of the image.

is.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v){Intent intent = new Intent();intent.putExtra("imagePosition", gallery.getSelectedItemPosition());intent.setClass(MainActivity.this, RemoveClothActivity.class);startActivity(intent);}});

Create a View object as follows:
