Answer 3

From what I can gather from your question..

Do you want pinch zoom functionality in ImageView that you are using. then refer this link

Or

is it you are using an WebView to load your image from url and want zoom_in_out functionality in WebView then use

.getSettings().setBuiltInZoomControls(true);

link for clarity

If thats not what you want then let me know..
