问题 I've setup my tabs as follows: spec = tabHost.newTabSpec("tab1").setIndicator("Tab 1").setContent(intent); tabHost.addTab(spec); And now I have a tab that has no icon, only a title, but it just leaves an icon-sized blank space with the Title at the bottom - I tried adjusting the layout_height in the xml, but then the text is gone because it is rendered below the cutoff point. How can I change the size of a tab, and have the title displayed without an icon? 回答1: The answer is simple: You can't

问题 I have problem in getting the size of the file using Lua. I am creating a function method that if the file size of the file is 743 bytes , then the file will be deleted. Here is my code : local getDLFile = function(fileToDL) local path = system.pathForFile(fileToDL, system.DocumentsDirectory ) local myFile = io.open( path, "w+b" ) http.request{ url = "http://www.testfile.com/"..fileToDL, sink = ltn12.sink.file(myFile), } -- i don't know what is the syntax if myFile.size == 743 bytes then

问题 std::string array[] = { "one", "two", "three" }; How do I find out the length of the array in code? 回答1: You can use std::begin and std::end , if you have C++11 support.: int len = std::end(array)-std::begin(array); // or std::distance(std::begin(array, std::end(array)); Alternatively, you write your own template function: template< class T, size_t N > size_t size( const T (&)[N] ) { return N; } size_t len = size(array); This would work in C++03. If you were to use it in C++11, it would be
