java - ArrayList not working as expected in do..while loop -

-

i have following loop creates string fits in screen, creates page speak.

    (int = 0; < totalline; i++) {          temp = enterline(mtextview, texttobeshown, i);             full = full + temp;      }

so after iteration done full holds 1 page.

what want create outer iteration allows me create more 1 page, amount of pages created isn't defined. iteration needs stop if there aren't more pages created.

i tried following code reason when calling page pages.get(1) gives out whole string not full / page. example if 3 strings have been added arraylist pages there 3 strings in arraylist same value.

with testing log, know first iteration working well, , full gives expected values meaning in first do iteration gives out expected values full second iteration etc..

    do{     (int = 0; < totalline; i++) {          temp = enterline(mtextview, texttobeshown, i);         if(temp.trim().length() == 0){             break;         }else{             full = full + temp;         }     }     pages.add(full);

so question doing wrong arraylist , why isn't working i'm expecting.

edit

this enterline code: more log's used didn't feel need display them all.

public string enterline(textview mtextview, string textbeshown, int i){          string a;         int number = mtextview.getpaint().breaktext(texttobeshown, 0, texttobeshown.length(),true,mtextview.getwidth(), null);          if(texttobeshown.substring(number-1,number) != " "){             number = texttobeshown.substring(0,number).lastindexof(" ");             log.e("tag1", "found " + i);         }          = (texttobeshown.substring(0, number) + "\n");         log.e(tag, texttobeshown.substring(0, number));         texttobeshown = texttobeshown.substring(number, texttobeshown.length());         return a;     } 

do{     full=""     (int = 0; < totalline; i++) {         temp = enterline(mtextview, texttobeshown, i);         if(temp.trim().length() == 0){             break;         }else{             full = full + temp;         }     }     pages.add(full); }while(...)

or better

do{     stringbuilder builder = new stringbuilder();     (int = 0; < totalline; i++) {         temp = enterline(mtextview, texttobeshown, i));         if(temp.trim().length() == 0){             break;         }else{             builder.append(temp);         }     }     pages.add(builder.tostring()); }while(...)

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.
