Can we give separate width property for each tab? i.e, one with larger width and other with smaller? 回答1: We can mention the tab width in code like: tabHost . getTabWidget (). getChildAt ( 0 ). getLayoutParams (). width = 50 ; 回答2: I tried below code and it worked perfectly fine for me LayoutParams params = tabHost . getTabWidget (). getChildAt ( 0 ). getLayoutParams (); params . width = 170 ; params . height = 120 ; tabHost . getTabWidget (). getChildAt ( 0 ). setLayoutParams ( params ); you

But why not go through each string and simply count how many times each letter turns up. Given appropriate implementation, this shouldn't take more than O(n) time. 回答2: generate a prime number array[26] each prime number represent a character, then when you traverse the string, multiple each character's prime number, if equal, it is anagrams, otherwise not. it

As I understand it for the four most common subsampling variants are setup as follows (I could be way off here): 4:4:4 - An MCU block of 8x8 pixels with Y, Cb, and Cr represented in each pixel. 4:2:2 - An MCU block of 16x8 pixels with Y in each pixel and Cb, Cr every two pixels 4:2:0 - An MCU block of 16x16 pixels with Y every two pixels and Cb,

Is there a way to run 'each' on only the elements in a set who were not clicked? Or is there a better way? 回答1: you can use :not(this) so change : $('a.parent').each(function(){ $

I'll be using verbs DoString and DoNum: chain =: (('string';'num') i. columnTypes) { DoString`DoNum EDIT: The column descriptors are important, the decision on which verb to use is based on them, not on the type itself . In reality, I

For example, with df <- data.frame(a = runif(10), b = rnorm(10)) I might attempt to do one of the following, but they all return errors: library(dplyr) > df %>% + mutate_each(funs((function(x){x/2})), a, b) Error in eval(substitute(expr), envir, enclos) : Unsupported type CLOSXP for column "a" > > df %>% + mutate_each

I've search but I couldn't find anything useful. My code is like this: function render() { // each 2 seconds call the createNewObject() function if(eachTwoSecond) { createNewObject(); } requestAnimationFrame(render); renderer.render(scene, camera); } Any Idea? 回答1: requestAnimationFrame passes single parameter to your callback which indicates the current time (in ms) when requestAnimationFrame fires the
