Is it a good thing to write logic based on the hex value of id generated in R.java android -

-

this have seen in android application. have number of image buttons ids

r.java :         public static final int img1=0x7f090080;         public static final int img2=0x7f090081;         public static final int img3=0x7f090082;         public static final int img4=0x7f090083;         public static final int img5=0x7f090084;         public static final int img6=0x7f090085;         public static final int img7=0x7f090086;         public static final int img8=0x7f090087;

in 1 of activity traversing loop below:

for (int = 0; < noofbuttons; i++) {     if (i == pos) {         ((imageview) vi.findviewbyid(r.id.img1 + i)).setimageresource(r.drawable.circular_pagination_red);     } else {         ((imageview) vi.findviewbyid(r.id.img1 + i)).setimageresource(r.drawable.circular_pagination_brown); }

i want know how safe , advisable is. 1 thing working absolutely fine. been part of months , never seen problem in logic. still irks me bit.

note : not getting error , know alternate solution also. concern if not advisable/safe want know why? scenarios can create havoc me. have understanding r.java.

though might work ok of times, not advisable. r class generated automatically have no control on , change. there solution problem using typed array in resources. check example this answer.

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a
