use the lib https://github.com/chrisbanes/PhotoView
In code
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);
}
// If you later call mImageView.setImageDrawable/setImageBitmap/setImageResource/etc then you just need to call
attacher.update();
