java - Starting activity on mouse click makes animation slow -


so developing android application in have home screen , screen content of app. on home screen have button navigates user content's screen (actually image view used button). when clicked button should start animation of being clicked , start activity of content screen. works pretty bad , slow, when click button animation starts slows down (lags). tried changing event click tap , lots of other possible solutions none worked. tried commenting "startactivity" method , fixed it, animation running smoothly. need startactivity method, best approach here, how can fix this. can putting startactivity in different thread work, i'm not sure how if well

this code:

((button)findviewbyid(r.id.btnplay)).setonclicklistener(new view.onclicklistener() {         @override         public void onclick(final view v) {             //shake.reset();             findviewbyid(r.id.btnplay).startanimation(shake);              shake.setanimationlistener(new animation.animationlistener() {                 intent i;                  @override                 public void onanimationstart(animation animation) {                     = new intent(v.getcontext(), gameactivity.class);                     startactivity(i);                 }                  @override                 public void onanimationend(animation animation) {                     ((button) findviewbyid(r.id.btnplay)).setvisibility(view.invisible);                 }                  @override                 public void onanimationrepeat(animation animation) {                  }             });         }     });

shake animation loaded custom xml file. have same animation in content screen , runs smoothly, of course there no startactivity there. here code:

<set xmlns:android="http://schemas.android.com/apk/res/android"> <rotate     android:duration="70"     android:fromdegrees="-5"     android:pivotx="50%"     android:pivoty="50%"     android:repeatcount="5"     android:repeatmode="reverse"     android:interpolator="@android:anim/linear_interpolator"     android:todegrees="5" /> <translate     android:fromxdelta="-10"     android:toxdelta="10"     android:repeatcount="5"     android:repeatmode="reverse"     android:interpolator="@android:anim/linear_interpolator"     android:duration="70" />

move these lines of code in onanimationend() 

i = new intent(v.getcontext(), gameactivity.class); startactivity(i);

update

i've tried code , works me: 

    animation animation = animationutils.loadanimation(myapplication.getappcontext(), r.anim.shake);      public void onclick(view v) {         if (v.getid() == r.id.btnplay) {             animation.setanimationlistener(new animation.animationlistener() {                 @override                 public void onanimationstart(animation animation) {                  }                  @override                 public void onanimationend(animation animation) {                     intent intent = new intent(getactivity(), articleactivity.class);                     startactivity(intent);                 }                  @override                 public void onanimationrepeat(animation animation) {                  }             });             v.startanimation(animation);         }     }

if activity starts when animation of button starts, there many things (like: button animation, execution of activity lifecycle methods including lifecycle methods of fragments, animation used transition between activities) executed on main thread => button animation stuck (the animation won't smooth).

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
