size

I have an menuscreen XML. When I open the project wide screen Its not adapted all screen size. How can I overcome this problem. When I want to add picture about this problem I think I need 10 rep. point :) Could anyone help me ? <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ScrollView1" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <LinearLayout android:layout_width="match

零、前言 对于函数 operator new 和 operator delete 来说，分为全局重载和局部重载。 全局重载的形式： void *::operator new(size_t size); void ::operator delete(void *pdata); 局部重载的形式： void *A::operator new(size_t size); void A::operator delete(void *pdata); 一、operator new 和 operator delete 源码 # include <iostream> void * operator new ( size_t size) { std :: cout << "全局的 operator new 重载函数。" << std :: endl ; return malloc (size); } void operator delete ( void *pdata) { std :: cout << "全局的 operator delete 重载函数。" << std :: endl ; free (pdata); } class CTest { public : CTest() { std :: cout << "构造函数" << std :: endl ; } ~CTest() { std :

I make an exercise about html with several input buttons: http://bullmalay.appspot.com/ I visit it on my mobile. But I find the text size is really small. I think the reason is about resolution. Can anyone help me about the text size? I want it can display the similar size in my laptop. ps. I have searched about css:@media (min-width: 702px) and then set the font size. But I think even a small device can have a resolution high than my laptop.The size will be smaller than it display on my laptop screen. I think the size should be: fontSize * (width per pixel of my laptop)/(width per pixel of

I'm having problems with how items appear in the Android Studio Designer and my phone. The first problem is that widgets & fragments appear differently in the designer/emulator than on my phone. I have tried lowering the resolution in the designer to test other device resolutions but it still appears differently on my phone despite the resolutions being relatively the same. Designer view: http://i.imgur.com/5kZKFDd.png HTC Desire 510: http://i.imgur.com/SqDiyBy.png The designer view is using the Nexus S's resolution which is smaller than my phone's resolution, yet the items still appear

##### LeetCode-102 Solution1: 直接使用队列, 每次处理一层. class Solution { // 层次遍历, 使用队列. 93.41%. public : vector < vector < int > > levelOrder ( TreeNode * root ) { vector < vector < int > > retvec ; if ( root == NULL ) return retvec ; queue < TreeNode * > q ; q . push ( root ) ; int size ; while ( ! q . empty ( ) ) { size = q . size ( ) ; vector < int > vec ; // 每次处理一层. for ( int i = 0 ; i < size ; i ++ , q . pop ( ) ) { vec . push_back ( q . front ( ) - > val ) ; if ( q . front ( ) - > left ) q . push ( q . front ( ) - > left ) ; if ( q . front ( ) - > right ) q . push ( q . front ( ) - > right ) ; }

线程是操作系统中独立的个体，如果不经过处理就不能成为一个整体。使线程进行通信后，系统之间的交互性会更强大，在大大提高CPU利用率的同时还能够对个线程任务在处理过程中进行有效的把控和监督。 等待/通知机制 首先看一下一个不用等待/通知机制实现线程间通信的例子，使用sleep结合while（true）死循环来实现. public class MyList { private List list = new ArrayList(); public void add(){ list.add(" "); } public int size() { return list.size(); } } public class ThreadA extends Thread { MyList myList; public ThreadA(MyList list){ this.myList= list; } public void run(){ for(int i= 0; i < 10; i ++){ myList.add(); ThreadA.sleep(1000); } } } public class ThreadB extends Thread { MyList myList; public ThreadB(MyList list){ this.myList= list; } public

I want the tabs in my tabpane to fit the complete size of the tabpane which they are in. So basically there shall be no header area visible, everything should be covered by the tabs. I have 2 problems here: How can I make the tabs dynamically fit the width of the tabpane? How can I fit them to the correct height, and remove the little spaces between the tabs? I suppose this is done via css, but I don't quite know how. greets You can simply add a listener to the TabPane to detect any changes and adjust the width and/or height of the tabs accordingly. @FXML private JFXTabPane tabPane; Divide the
