I'm creating a custom view derived from GridView. This contains a custom ImageView with zooming and panning functionality. Scroll and zoom functionality is sluggish. If the parent view is the same custom ImageView instead of a GridView it works perfectly. I'm trying to do this because I need a static background image with an interactive area at the center. Zoom and scroll are implemented similar to this article: http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2-part-6-implementing-the-pinch-zoom-gesture/1847 I uploaded a test project reproducing the problem here: http://www.steema.com/files/public/support/HelloAndroid.zip. The OnCreate method is implemented like this: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); View myView1; boolean sluggish = false; if (sluggish) { myView1 = new MyGridView(this); } else { myView1 = new MyImageView(this); } setContentView(myView1); } If you set the sluggish variable to true you'll see ImageView works much better for that. Do you have any idea why using GridView turns zoom and scroll unusable or how can this be solved? I'm not using a "dynamic" ImageView into a "static" ImageView because I haven't found how to embed an ImageView into another ImageView.
