javascript - Injecting JQuery into Android Webview -

-

i working on project translate webpage , displaying in android app. have done injecting javascript webview android using following code:

@override public void onpagefinished(webview view, string url) {      string jap = "お問い合わせ";     string eng = "contact us";      mwebview.loadurl("javascript:(function(){" +             "var jpf = '"+jap+"';" +             "var jp = new regexp(jpf,'g');" +             "var en = '"+eng+"';" +             "document.body.innerhtml = " +             "document.body.innerhtml.replace(jp,en);" +             "})()"); }

however, ineffective method, because search each term , replace it. because of this, tried similar jquery's dictionary:

@override public void onpagefinished(webview view, string url) {         mwebview.loadurl("javascript (function(){" +                         "var mydictionary = {" +     "jp : {" +     "'お問い合わせ' : 'contact us'" +     "}" +     "}" +     "$.tr.dictionary(mydictionary);" +     "$.tr.language('jp');" +     "var tr = $.tr.translator();" +     "alert(tr('お問い合わせ'))" +           "})()"); }

this not seem work. please help.

note: planning fill dictionary more words one. first code, have made loop changes variables jap , eng, inefficient. chose not include code increase simplicity. thanks

enable javascript

webviews don't allow javascript default. run web application in web view, need explicitly enable javascript adding following lines oncreate method:

// enable javascript websettings websettings = mwebview.getsettings(); websettings.setjavascriptenabled(true);

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

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...
