listview - Android OnTouchEvent: Debugging InputEventConsistencyVerifier messages -

-

i have layout configured gesture listener ontouchevent(). layout contains listview , using gestures capture row id of listview. have following code -

 itemslist.setontouchlistener(new ontouchlistener() {          @override         public boolean ontouch(view arg0, motionevent evt) {             // todo auto-generated method stub             //             int action = evt.getaction();             final string debug_tag = "debug";             detector.ontouchevent(evt);             switch(action) {                 case (motionevent.action_down) :                     log.d(debug_tag,"action down");                     return true;                 case (motionevent.action_move) :                     log.d(debug_tag,"action move");                     return true;                 case (motionevent.action_up) :                     log.d(debug_tag,"action up");                     return true;                 case (motionevent.action_cancel) :                     log.d(debug_tag,"action cancel");                     return true;                 case (motionevent.action_outside) :                     log.d(debug_tag,"movement occurred outside bounds " +                             "of current screen element");                     return true;                 }               return false;         }      });

detector gesturedetector instance. using swipe left or swipe right actions on row of listview.

whenever swipe left / right receive 3 debug messages in logcat (information or at??).

d/inputeventconsistencyverifier(24700): touchevent: action_move contained 1 pointers  there 0 pointers down.  d/inputeventconsistencyverifier(24700):   in android.view.gesturedetector@b50cf9b0  d/inputeventconsistencyverifier(23596):   0: sent @ 37751425150760,  motionevent { action=action_move, id[0]=0, x[0]=39.00721, y[0]=28.526703, tooltype[0]=tool_type_finger,  buttonstate=0, metastate=0, flags=0x0, edgeflags=0x0, pointercount=1, historysize=1, eventtime=37751425,  downtime=37751133, deviceid=0, source=0x1002 }

there 4 debug messages ontouchlistener -

action action move action action move action action move action action

which corresponds swipe movement believe.

the main activity class extends ongesturelistener hence has unimplemented methods such onfling.. etc etc.

the problem onfling method called after action up event , when occurs argument passed method mevt1 null while mevt2 not null. (default behaviour?)

onfling(motionevent mevt1, motionevent mevt2, float velx, float vely)

the method uses mevt1 , hence causes nullpointexception.

i want know if debug messages inputeventconsistencyverifier of concern , if knows if problem @ all?

you have call

detector.ontouchevent(evt)

for every action, not action_move

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
