kindly me regarding same. please find attached code below of have tried.
galleryfragment.java
gv_folder = (gridview)view.findviewbyid(r.id.gv_folder); gv_folder.setonitemclicklistener(new adapterview.onitemclicklistener() { @override public void onitemclick(adapterview<?> adapterview, view view, int i, long l) { intent intent = new intent(getcontext(), photosactivity.class); intent.putextra("value",i); startactivity(intent); } }); photosactivity.java
gridview = (gridview)findviewbyid(r.id.gv_folder); int_position = getintent().getintextra("value", 0); adapter = new gridviewadapter(this, galleryfragment.al_images,int_position); gridview.setadapter(adapter); gridview.setonitemclicklistener(new adapterview.onitemclicklistener() { @override public void onitemclick(final adapterview<?> parent, view view, final int position, long id) { charsequence options[] = new charsequence[]{"add memory", "listen short memory?", "listen long memory?", "fullscreen slideshow"}; // if(position == 0) { //options = new charsequence[]{"add memory", "listen short memory?", "listen long memory?", "fullscreen slideshow"}; // }else{ // options = new charsequence[]{"add memory", "listen short memory?", "listen long memory?"}; // } alertdialog.builder builder = new alertdialog.builder(photosactivity.this); builder.setitems(options, new dialoginterface.onclicklistener() { @override public void onclick(dialoginterface dialog, int which) { else if(which == 3){ intent intent = new intent(photosactivity.this, fullscreenviewactivity.class); intent.putextra("position", int_position); startactivity(intent); } } }); builder.show(); } }); gridviewadapter.java
