开发app的时候,比较麻烦的地方,就是处理屏幕适配,比如文字设为12的大小,测试的时候,看得文字挺正常,可是,放到高分辨率设备一看,文字就变得特别小, 怎样实现随着分辨率变大或者变小,所有的size数值,也会等比例变化呢? 首先,在App类,加两个static变量,用来获取屏幕大小 public partial class App : Application { public App () { InitializeComponent(); MainPage = new App1.MainPage
1. create a 1G file for the swap. sudo fallocate -l 1G /swapfile we can verify that the correct amount of space was reserved by typing: ls -lh /swapfile 2. Enabling the Swap File. 1.Make the file only accessible by typing: sudo chmod 600 /swapfile. 2
编译llvm的时候:collect2:ld terminated with signal 9(或11) 1 Creating a file for 1024 MB size you want: We will create a /mnt/1024MB.swap swap file and set the permissions so that users cannot read it directly. [root@localhost mnt]# count= /mnt/1024MB.swap
