android - Translate animation created programmatically has incorrect duration and offset -

-

here's needs done:

i have top bar 3 buttons. 2 on right can pressed , nothing interesting them. left 1 replaces 3 buttons other three. animation: middle , right (new ones) buttons slide out left button's position corresponding places, while old buttons fade out. left button gets replaced without movement: old 1 fades out, new 1 fades in.

how done:

final animation fadeout, fadein; animation fadeoutwithlistener; fadein = animationutils.loadanimation(this, r.anim.camera_top_bar_fade_in); fadeout = animationutils.loadanimation(this, r.anim.camera_top_bar_fade_out); final translateanimation slideanim;  slideanim = new translateanimation(     animation.relative_to_parent, -flashautobtn.getleft(),     animation.relative_to_self, 0,     animation.relative_to_self, 0,     animation.relative_to_self, 0); slideanim.setduration(1000l); slideanim.setstartoffset(0); fadeoutwithlistener = animationutils.loadanimation(this, r.anim.camera_top_bar_fade_out); fadeoutwithlistener.setanimationlistener(new animation.animationlistener() {     @override     public void onanimationstart(animation animation) {         flashautobtn.startanimation(fadein);         flashonbtn.startanimation(slideanim);         flashoffbtn.startanimation(slideanim);     }     @override     public void onanimationend(animation animation) {         flashbtn.setvisibility(view.invisible);         gridbtn.setvisibility(view.invisible);         switchcamerasidebtn.setvisibility(view.invisible);         flashautobtn.setvisibility(view.visible);         flashoffbtn.setvisibility(view.visible);         flashonbtn.setvisibility(view.visible);     }     @override     public void onanimationrepeat(animation animation) { } });  flashbtn.startanimation(fadeoutwithlistener); gridbtn.startanimation(fadeout); switchcamerasidebtn.startanimation(fadeout);

how works: fadein/out animations ok - defined in xml, have duration set 1000 , last 1 second. no offset.

two translation animations work incorrectly: first, don't start @ same time fadeoutwithlistener animation. instead, wait 100 or 200 ms (with duration of 100 or 200 ms) flash transformation (coordinates correct btw) , disappear. after fadeoutwithlistener done - listener's onanimationend fires , buttons become visible.

this final try - before did without listener - consecutive calls of startanimation , setvisibility - same identical behavior.

if apply 2 animation same ui @ same time, remember, latest 1 performed.

to make multiple animation @ same time, need use animationset

animationset set = new animationset(false); set.addanimation(fadeout); set.addanimation(slideout); view.setanimation(set); set.start();

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...
