below class , xml want image swipe_view screen

full_zoom.java

package com.td.gridview; import android.os.bundle; import android.app.activity; public class full_zoom extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.full_view); } }

full_view.xml

_________________________________________________________________________________

this tried after trying happens position selected grid image not swipe_view screen. want , send image swipe_view screen not selected grid image.

because want zoom current swiping image in new screen.

but because of code

// intent info intent i3 = getintent(); // selected image id int position = i3.getextras().getint("id"); // sending image id fullscreenactivity intent i2 = new intent(getapplicationcontext(), full_zoom.class); // passing array index i2.putextra(null, r.id.view_pager); startactivity(i2);

it image selected grid view want image current showing swiping image.

swipeactivity.java

//send image full_view.xml screen on button click button b = (button)findviewbyid(r.id.xoom); b.setonclicklistener(new view.onclicklistener() { public void onclick(view v) { // // todo auto-generated method stub // intent info intent i3 = getintent(); // selected image id int position = i3.getextras().getint("id"); // sending image id fullscreenactivity intent i2 = new intent(getapplicationcontext(), full_zoom.class); // passing array index i2.putextra(null, r.id.view_pager); startactivity(i2); } }); //

full_zoom.java(new screen class)

public class full_zoom extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.full_view); // intent info intent = getintent(); // selected image id int position = i.getextras().getint("id"); viewpager viewpager = (viewpager) findviewbyid(r.id.view_pager); pinchzoom img = new pinchzoom(this); img.setimageresource(mainactivity.icons[r.id.view_pager]); img.setmaxzoom(4f); setcontentview(img); } }

send image within onclick:

intent = new intent(this,yourclassname.class); i.putextra("imageid", icons[position]); startactivity(i);

get on new activity :

bundle bd = getintent().getextras(); int imageres = bd.getint("imageid"); imageview image = (imageview) findviewbyid(r.id.imageview); image.setimageresource(imageres);
