when using viewpager, there advantage using tablayout instead of pagertabstrip or vice versa? or equivalent? 1 more convenient other? 1 offer greater functionality? again questions asked, , answers expected, in context of viewpager. thanks. tablayout material concept replaced deprecated actionbar tabs in android 5.0. extends horizontalscrollview, can keep adding tabs horizontally can include text, icons, or custom views , scroll through them linearly without paging. tablayout provides setupwithviewpager(viewpager viewpager) method attach viewpager instead of being part of viewpager pagertabstrip. a pagertabstrip more of indictor current page of viewpager, , "it intended used child view of viewpager widget". scrolling not act tablayout since each tab part of page instead of individually horizontally scrollable.

i'd split rails using git submodule, far can tell, works directory. while works file structure similar python's django, each module has models.py, views.py, etc, doesn't appear work rails, gives directory structure there views folder, controllers folder, etc, each folder having 1 file module. is there way convert file structure similar django's, or if not, how use git submodules rails? how use git submodules rails? you not use them, not directly @ least. git submodule repo, checked out in own folder. if couple deployment script linked (symlink) files rails directory structure files submodule folder, rail app.

i new c++ , in mpi programming. have confused code block in c++ int count; count=4; local_array=(int*)malloc(count*sizeof(int)); why using sizeof(int) here in mpi programming? i see you're trying allocate 4 int s here. if @ malloc 's signature, takes number of bytes first parameter. stated here , int data type takes 4 bytes. therefore, if want 4 int s, have typed local_array=(int*)malloc(count*4); . not remembers int actualy takes 4 bytes. that's why use sizeof find out actual size of object or type.
