Answer 1

I will highly recommend having a look at Photo View:

https://github.com/chrisbanes/PhotoView

It was developed by Chris Banes who is one of the actual developers that worked on the Android development team, so you can't go wrong here. This library will save you A LOT of headaches.

Usage is as simple as:

ImageView mImageView;
PhotoViewAttacher mAttacher;

@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  // Any implementation of ImageView can be used!
  mImageView = (ImageView) findViewById(R.id.iv_photo);

  // Set the Drawable displayed
  Drawable bitmap = getResources().getDrawable(R.drawable.wallpaper);
  mImageView.setImageDrawable(bitmap);

  // Attach a PhotoViewAttacher, which takes care of all of the zooming functionality.
  mAttacher = new PhotoViewAttacher(mImageView);
}
