android - How to display .gif file in imageview? -
my layout have lots of imageviews. want show .gif animated file in 1 imageview. tried yash method (adding gif image in imageview in android) .gif file shown layout. other views dissappeared.
i want show all.
any idea?
put .gif file res/raw folder, in fragment or activity , can set gif in imageview like
gifanimationdrawable gif; try { gif = new gifanimationdrawable(getresources().openrawresource(r.raw.download)); gif.setoneshot(false); } catch (notfoundexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } ivgif.setimagedrawable(gif); gif.setvisible(true, true); } 1)gifanimationdrawable .java
