How to change the delay of sleep/timer thread in android during runtime?

时光怂恿深爱的人放手 提交于 2019-12-10 13:16:18
问题 What I was trying to do was to decrease the timer delay every time the counter becomes a multiple of 5. But, as soon as the code entered the if block, it stopped incrementing the timer. I can't understand what is happening. This is the code thread=new Thread(){ public void run(){ try{ if(count%5==0) timre--; else{ //do nothing } //*******PROGRESS UPDATE********// for(t=0;t<=100;t++) { sleep((timre) / 100); progress.setProgress(t); t += 1; } //****PROGRESS UPDATE OVER****// } catch

C# DLL run-time error - builds, runs, but throws unhandled exception upon trying to use DLL functions

问题 I am trying to compile the example project shown here for C#. It had to be converted to VS2010, but that worked fine. It builds, runs, but then dies when it tries to access a DLL function. I made a series of images to show my steps. As you can see, the device I designed is attached and correctly configured, but I really don't think that has anything to do with the issue. Inside the Form1.cs file, the following comment explains how to use the DLL: /* PLEASE NOTE You must add a reference to the

Can SIFT run in realtime?

老子叫甜甜 提交于 2019-12-10 12:08:37
问题 Is there any C/C++ implementation of SIFT that runs in realtime in a processor of ~2.2GHz and a RAM of 4GB? Or what is the lowest achievable runtime for extracting SIFT features and descriptors of ~2000 keypoints. The C++ implementation by Andrew Vedaldi takes around 3.5 seconds for 2000 keypoints. 回答1: Generaly NO. Exact implementation of SIFT can't run in real time even with modern PC. But there is a implementations on GPU http://cs.unc.edu/~ccwu/siftgpu/. The faster alternative is SURF,

Is it possible to change the definition of structs at runtime? [closed]

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I don't know why you would ever want to do this, but I was curious if anyone knew the answer. Is it possible at run time to use one struct definition for a while, and then later change that definition? i.e.

Set drawable dynamically for AnalogClock widget

问题 How to do that? I have AnalogClock on my xml. And I want drawable for the android:dial to change programatically. I tried remoteviews.setImageViewResource(R.id.AnalogClock, R.drawable.w0); or remoteviews.setInt(R.id.AnalogClock, "setDialResource", R.drawable.w0); Both can not accomplish it. Anyone manage to do this? 回答1: Finally make it works. I put transparent image on AnalogClock android:dial Then use FrameLayout to overlay ImageView and AnalogClock. Then use remoteviews.setInt(R.id

Can I count on this ASP.NET event log source always being registered?

问题 Unhandled exceptions cause ASP.NET-based applications to unexpectedly quit in the .NET Framework 2.0 makes me think that an event log source named with the following convention will always be registered on any box where the .NET Framework has been installed: "ASP.NET X.Y.Z.0" Where X, Y, and Z are the major, minor, and build numbers from the .NET runtime. Is it safe to assume that the installation of the .NET Framework will always create this event log source? 回答1: This event log source is

认识注解 什么是注解? 注解的语法是 @注解名 ,多用来替代配置文件配置项。它是由框架解读的(使用反射)。可以把注解对比注释理解,注释是给人看的,注解是给框架看的。 注解的使用 注解定义:框架的工作 注解使用:我们的工作 注解解读:框架的工作 定义一个注解 所有注解的父接口都是annotation的子接口 // 定义注解 public @interface MyAnno1 { } 可以使用注解的位置: /** * 注解默认可以用在 * 类、构造方法、方法、成员变量、形参、局部变量、包(不常用)上 */ @MyAnno1 public class Demo1 { @MyAnno1 private String name; @MyAnno1 public Demo1() { } @MyAnno1 public void fun1(@MyAnno1 String param) { @MyAnno1 String s = "demo"; } } 注解属性 注解的属性 @MyAnno1(age = 20, name = "张三") public class Demo2 { } // 注解属性的书写方式 @interface MyAnno1 { int age(); String name(); } 注解属性的默认值 // 可以不需要给带有默认值得属性赋值 @MyAnno1(name =

How can I add a jar to an APK & make the APK refer to it without Eclipse?

守給你的承諾、 提交于 2019-12-10 10:34:10
问题 This may seem a bit weird, but I need to implement it. I have an APK & I dont have its source code. Now I can break the apk , modify & repack it, but while doing so, I need to add my custom jar to it & make the app/apk refer this library/jar at run time. If I just create a folder libs inside the apk & put my jar inside, I get a NoClassDefFound error. Any idea how to implement it using ANT or any other tool ? Thanx in advance 回答1: The Jar(s) you attach in your android project, are not copied
