问题 I am using Swing and AWT (for the listeners) to make a small program. I have a problem concerning getting the size of my JPanel (the class named Chess). My Layout: public class Main extends JFrame implements MouseListener, ActionListener{ Chess chessPanel = new Chess (); JButton newGameButton = new JButton ("New Game"); JButton loadGameButton = new JButton ("Load Game"); JButton saveGameButton = new JButton ("Save Game"); JButton exitButton = new JButton ("Exit"); public static void main

问题 I want to know how to automatically adjust the size of the TextView according to the length of the String . I am getting some data from another Intent as a String and storing it in a TextView . If I leave it small, the whole text won't fit and only half of it is displayed. If I leave a big space for the TextView it does not look nice on the screen. The solution I found online was using extends TextView and using this method gives errors in my class and I have to change a lot of functions

问题 The question is how to get the length of dynamically allocated 2D Arrays in C? I thought the code below should get the number of rows, but it doesn't. char** lines; /* memory allocation and data manipulation */ int length; //the number of rows length = sizeof(lines)/sizeof(char*); Any thoughts on this? 回答1: You can't get the length of dynamically allocated arrays in C (2D or otherwise). If you need that information save it to a variable (or at least a way to calculate it) when the memory is

问题 I'm having a problem where I cannot initialize an array without hard-coding it in Java. So this is the hard-code version which works: int numberOfElements = inputFromFile(args[0], myArray); int [] myArray = new int[1000]; inputFromFile is basically going to be a method I'm going to write that can read the numberOfElements from a textfile along with my program. I tried fixing it without hardcoding and got my result to be this: int numberOfElements = inputFromFile(args[0], myArray); int []
