android - R Class Error in my project -


i r class error in project. tried cleaning project, changing property , restarting eclipse.

@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         applicationcontext = this.getapplicationcontext();         eventdata = new eventdatasqlhelper(this);          btnforaway = (button) findviewbyid(r.id.btnforaway);         btnfordriving = (button) findviewbyid(r.id.btnfordriving);         txtdefaultmain = (textview) findviewbyid(r.id.txtdefaultmain);          btnforaway.setonclicklistener(new onclicklistener() {             @override             public void onclick(view v) {                 appmode = away_mode;                  launchaway();              }         });

here r.id error in every file of project

if there error in resource folder ,r.java file not generate automatically. check console errors in xml .and if create image in drawable folder caps lock or numbers time r.java file not generate automatically.

if there no errors in console follow these steps :

  1. project==>uncheck build automatically
  2. project==>clean
  3. right click on project , select build project
  4. right click on project , select android tools , select fix project properties

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
