i managed save image imageview gallery onlongclicklistner() of code given below. problem save last image dosent matters image try save.
public class capturephotoutils { public final string insertimage(contentresolver cr, bitmap source, string title, string description) { contentvalues values = new contentvalues(); values.put(mediastore.images.media.title, title); values.put(mediastore.images.media.display_name, title); values.put(mediastore.images.media.description, description); values.put(mediastore.images.media.mime_type, "image/jpeg"); // add date meta data ensure image added @ front of gallery values.put(mediastore.images.media.date_added, system.currenttimemillis()); values.put(mediastore.images.media.date_taken, system.currenttimemillis()); uri url = null; string stringurl = null; /* value returned */ try { url = cr.insert(mediastore.images.media.external_content_uri, values); if (source != null) { outputstream imageout = cr.openoutputstream(url); try { source.compress(bitmap.compressformat.jpeg, 50, imageout); } { imageout.close(); } long id = contenturis.parseid(url); // wait until mini_kind thumbnail generated. bitmap minithumb = mediastore.images.thumbnails.getthumbnail(cr, id, mediastore.images.thumbnails.mini_kind, null); // backward compatibility. storethumbnail(cr, minithumb, id, 50f, 50f, mediastore.images.thumbnails.micro_kind); } else { cr.delete(url, null, null); url = null; } } catch (exception e) { if (url != null) { cr.delete(url, null, null); url = null; } } if (url != null) { stringurl = url.tostring(); } return stringurl; } private final bitmap storethumbnail( contentresolver cr, bitmap source, long id, float width, float height, int kind) { // create matrix scale matrix matrix = new matrix(); float scalex = width / source.getwidth(); float scaley = height / source.getheight(); matrix.setscale(scalex, scaley); bitmap thumb = bitmap.createbitmap(source, 0, 0, source.getwidth(), source.getheight(), matrix, true ); contentvalues values = new contentvalues(4); values.put(mediastore.images.thumbnails.kind,kind); values.put(mediastore.images.thumbnails.image_id,(int)id); values.put(mediastore.images.thumbnails.height,thumb.getheight()); values.put(mediastore.images.thumbnails.width,thumb.getwidth()); uri url = cr.insert(mediastore.images.thumbnails.external_content_uri, values); try { outputstream thumbout = cr.openoutputstream(url); thumb.compress(bitmap.compressformat.jpeg, 100, thumbout); thumbout.close(); return thumb; } catch (filenotfoundexception ex) { return null; } catch (ioexception ex) { return null; } } } i putting images viewpager getting images array of drawables
class custompageradapter extends pageradapter {
context mcontext; layoutinflater mlayoutinflater; public custompageradapter(context context) { mcontext = context; mlayoutinflater = (layoutinflater) mcontext.getsystemservice(context.layout_inflater_service); } @override public int getcount() { return mresources.length; } @override public boolean isviewfromobject(view view, object object) { return view == ((linearlayout) object); } @override public object instantiateitem(viewgroup container, int position) { view itemview = mlayoutinflater.inflate(r.layout.image_slider_item, container, false); imageview = (touchimageview) itemview.findviewbyid(r.id.imageview); imageview.setimageresource(mresources[position]); imageview.setonlongclicklistener(new view.onlongclicklistener() { @override public boolean onlongclick(view view) { capturephotoutils photoutils = new capturephotoutils(); imageview.setdrawingcacheenabled(true); bitmap b = imageview.getdrawingcache(); photoutils.insertimage(full_screen_slider.this.getcontentresolver(), b, "1image", "this downloaded image sample"); toast.maketext(mcontext, "longpress ", toast.length_short).show(); return true; } }); container.addview(itemview); return itemview; } @override public void destroyitem(viewgroup container, int position, object object) { container.removeview((linearlayout) object); } }
replace this
@override public object instantiateitem(viewgroup container,final int position) { final view itemview = mlayoutinflater.inflate(r.layout.image_slider_item, container, false); final touchimageview imageview = (touchimageview) itemview.findviewbyid(r.id.imageview); imageview.setimageresource(mresources[position]); imageview.setonlongclicklistener(new view.onlongclicklistener() { @override public boolean onlongclick(view view) { capturephotoutils photoutils = new capturephotoutils(); imageview.setdrawingcacheenabled(true); bitmap b = imageview.getdrawingcache(); photoutils.insertimage(full_screen_slider.this.getcontentresolver(), b, "1image", "this downloaded image sample"); toast.maketext(mcontext, "longpress ", toast.length_short).show(); return true; } }); container.addview(itemview); return itemview; } it replacing view each time calls instantiateitem make final help.
