android - Countdown timer not working properly -

-

i trying use timer...when call countdowntimer.start()

i can see in debugger timeleft variable updated value=120000 want timer doesn't execute ontick method. jumps straight onfinish. if give timeleft literal works. 

    volatile long timeleft=0;     countdowntimer countdowntimer=new countdowntimer( timeleft,1000) {     @override     public void ontick(long timeleft) {             textview timeview= (textview)findviewbyid(r.id.timer);     long longtime=(timeleft / 1000);     integer inttime=(int)longtime;// convert long int     timeview.settext(string.valueof(inttime));}      @override     public void onfinish() {correctdialog("sorry,time up!!");}};}       (timeleft not fixed)

here first parameter in countdowntimer() constructor millisinfuture . giving value 0. finish whenever start timer. give value how time want execute times 10000 or 20000 etc...

so initialize timeleft

volatile long timeleft=10000;

check documentation countdowntimer

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i need build client web api in vba , needs work behind proxy (with authentication). i've been looking @ winhttp.winhttprequest , msxml2.xmlhttp/serverxmlhttp classes. turns out that: xmlhttp automatically detects proxy settings provided through proxy.pac file (good) winhttprequest doesn't (bad) however, on other hand: xmlhttp automatically follows redirects, , there's no way of disabling behaviour (bad) winhttprequest doesn't (good) since i'd able have cake , eat it, there way automatic proxy configuration component such winhttprequest doesn't follow redirects blindly? the vba-web project might pastry eating problem. https://github.com/vba-tools/vba-web i guess wish go like: dim client new webclient client .baseurl = "https://www.google.com" .proxyusername = <user> .proxypassword = <password> .enableautoproxy = true end dim request new webrequest request .method = webmethod.httpget ...

i want concatenate 2 csr_matrix, each shape=(1,n) . i know should use scipy.sparse.vstack : from scipy.sparse import csr_matrix,vstack c1 = csr_matrix([[1, 2]]) c2 = csr_matrix([[3, 4]]) print c1.shape,c2.shape print vstack([c1, c2], format='csr') #prints: (1, 2) (1, 2) (0, 0) 1 (0, 1) 2 (1, 0) 3 (1, 1) 4 however, code fails: from scipy.sparse import csr_matrix,vstack import numpy np y_train = np.array([1, 0, 1, 0, 1, 0]) x_train = csr_matrix([[1, 1], [-1, 1], [1, 0], [-1, 0], [1, -1], [-1, -1]]) c0 = x_train[y_train == 0].mean(axis=0) c1 = x_train[y_train == 1].mean(axis=0) print c0.shape, c1.shape #prints (1l, 2l) (1l, 2l) print c0,c1 #prints [[-1. 0.]] [[ 1. 0.]] print vstack([c0,c1], format='csr') the last line raises exception - file "c:\anaconda\lib\site-packages\scipy\sparse\construct.py", line 484, in vstack return bmat([[b] b in blocks], format=format, dtype=dtype) file "c:\anaconda\li...
