android - How to detect single tap on TouchImageView in ViewPager? -
i made app in displaying images inside viewpager. using universal image loader. images loading fine, , can zoom in , out because have added touchimageview imageview. when single tap on screen want display buttons, such share , delete. not able detect single touch gestures. why?
code viewpager
public class imageviewpager extends activity { // declare variable int position; button delete, gimmy, done; viewpager viewpager; imagepageradapter pageradapter; touchimageview imageview; textview text; runnable r; handler mhandler; relativelayout rel; gesturedetector gesturedetector; @suppresslint("newapi") @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); // set title viewpager setcontentview(r.layout.view_pager); mhandler=new handler(); delete=(button) findviewbyid(r.id.del); done=(button) findviewbyid(r.id.done); gimmy=(button) findviewbyid(r.id.gimmy); rel=(relativelayout)findviewbyid(r.id.relative); actionbar bar = getactionbar(); bar.setdisplayhomeasupenabled(true); bar.sethomebuttonenabled(true); settitle("viewpager"); intent p = getintent(); position = p.getextras().getint("id"); pageradapter = new imagepageradapter(imageviewpager.this); viewpager = (viewpager) findviewbyid(r.id.pager); viewpager.setadapter(pageradapter); viewpager.setcurrentitem(position); r=new runnable() { @override public void run() { // todo auto-generated method stub delete.setvisibility(view.gone); done.setvisibility(view.gone); gimmy.setvisibility(view.gone); } }; mhandler.postdelayed(r,5*1000); done.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { intent p = new intent(getapplicationcontext(), mainactivity.class); startactivity(p); } }); gimmy.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { } }); delete.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { } }); viewpager.setonpagechangelistener(new onpagechangelistener() { @override public void onpageselected (int page) { delete.setvisibility(view.gone); done.setvisibility(view.gone); gimmy.setvisibility(view.gone); } @override public void onpagescrolled (int arg0, float arg1, int arg2) { } @override public void onpagescrollstatechanged (int arg0) { } }); } @override public boolean onoptionsitemselected(menuitem item) { // todo auto-generated method stub switch (item.getitemid()) { case android.r.id.home: finish(); overridependingtransition(r.anim.slide_enter, r.anim.slide_exit); return true; default: return super.onoptionsitemselected(item); } } @override public boolean onkeydown(int keycode, keyevent event) { if (keycode == keyevent.keycode_back) { intent p = new intent(getapplicationcontext(), slideimages.class); // p.putextra("id", pos+1); startactivity(p); } return super.onkeydown(keycode, event); } } code pager adapter

i met same problem.just call single tap confirmed method & hide or show views on & add pager adapter same file.
code:

// set title viewpager setcontentview(r.layout.view_pager); mhandler=new handler(); delete=(button) findviewbyid(r.id.del); done=(button) findviewbyid(r.id.done); gimmy=(button) findviewbyid(r.id.gimmy); rel=(relativelayout)findviewbyid(r.id.relative); actionbar bar = getactionbar(); bar.setdisplayhomeasupenabled(true); bar.sethomebuttonenabled(true); settitle("viewpager"); intent p = getintent(); position = p.getextras().getint("id"); pageradapter = new imagepageradapter(imageviewpager.this); viewpager = (viewpager) findviewbyid(r.id.pager); viewpager.setadapter(pageradapter); viewpager.setcurrentitem(position); r=new runnable() { @override public void run() { // todo auto-generated method stub delete.setvisibility(view.gone);
