popup - Can android PopupWindow show another PopupWindow? -


can android popupwindow show popupwindow? how many popupwindow can opened in same time? one?

the first popupwindow displayed normally. on button click (which in first popupwindow contentview) having exception:

08-13 16:28:38.682: error/androidruntime(11760): fatal exception: main         android.view.windowmanager$badtokenexception: unable add window -- token android.view.viewrootimpl$w@41286250 not valid; activity running?         @ android.view.viewrootimpl.setview(viewrootimpl.java:600)         @ android.view.windowmanagerimpl.addview(windowmanagerimpl.java:313)         @ android.view.windowmanagerimpl.addview(windowmanagerimpl.java:215)         @ android.view.windowmanagerimpl$compatmodewrapper.addview(windowmanagerimpl.java:140)         @ android.view.window$localwindowmanager.addview(window.java:537)         @ android.widget.popupwindow.invokepopup(popupwindow.java:992)         @ android.widget.popupwindow.showasdropdown(popupwindow.java:901)         @ org.example.qberticus.quickactions.betterpopupwindow.showlikepopdownmenu(betterpopupwindow.java:159)         @ org.example.qberticus.quickactions.betterpopupwindow.showlikepopdownmenu(betterpopupwindow.java:129)         @ name.antonsmirnov.android.popup.ui.mainactivity$1$1.run(mainactivity.java:44)         @ android.app.activity.runonuithread(activity.java:4170)         @ name.antonsmirnov.android.popup.ui.mainactivity$1.onclick(mainactivity.java:42)         @ android.view.view.performclick(view.java:3558)         @ android.view.view$performclick.run(view.java:14157)         @ android.os.handler.handlecallback(handler.java:605)         @ android.os.handler.dispatchmessage(handler.java:92)         @ android.os.looper.loop(looper.java:137)         @ android.app.activitythread.main(activitythread.java:4514)         @ java.lang.reflect.method.invokenative(native method)         @ java.lang.reflect.method.invoke(method.java:511)         @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:790)         @ com.android.internal.os.zygoteinit.main(zygoteinit.java:557)         @ dalvik.system.nativestart.main(native method)

the code is:

    @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      setcontentview(r.layout.main);     bindcontrols();     initcontrols(); }  private button button;  private void bindcontrols() {     button = (button) findviewbyid(r.id.button); }  private void initcontrols() {     initbutton(button); }  private void initbutton(final button button) {     button.setonclicklistener(new view.onclicklistener() {         public void onclick(view view) {             final betterpopupwindow window = new betterpopupwindow(button);              view popupview = createpopupview();             window.setcontentview(popupview);             runonuithread(new runnable() {                 public void run() {                     window.showlikepopdownmenu();                 }             });         }     }); }  private view createpopupview() {     view v = layoutinflater.from(mainactivity.this).inflate(r.layout.window, null);     button popupbutton = (button) v.findviewbyid(r.id.popupbutton);     initbutton(popupbutton);     return v; }

after playing i've found that

    window.showatlocation(getwindow().getdecorview(), gravity.center, x, y);

works okay, but

    window.showasdropdown(getwindow().getdecorview(), gravity.center, x, y);

raises exception! if use showatlocation(view) view different getwindow().getdecorview() you'll still have exception.
