搜索条,其背景色随着界面的上下滑动而渐变 搜索条,其背景色随着界面的上下滑动而渐变。在这里考虑到搜索条的样式会根据UI进行设计,没有固定的样式,所以就直接写在了布局文件中。文中涉及到自定义轮播图控件ADViewPager 具体应用请阅读:######效果图:. 三:滑动监听 在布局文件中我们看到了SlidingScrollView,这是继承了ScrollView并重写了onScrollChanged(int l, int t, int oldl, int oldt)方法。从ScrollView的源码中我们找到了onScrollChanged这个方法,再仔细一看是包级私有的,我们无法使用,Google为什么这样做呢?虽然不可以直接用官方的控件,但是我们可以重写它,修改它的权限,这样我们就可以在外部使用了。 onScrollChanged里面有4个参数,l代表滑动后当前ScrollView可视界面的左上角在整个ScrollView的X轴中的位置,oldi也就是滑动前的X轴位置。同理,t也是当前可视界面的左上角在整个ScrollView的Y轴上的位置,oldt也就是移动前的Y轴位置。.

QUESTION
What we are trying to do is to list all properties of the class with NotNull attribute. The one from .NET, not from JetBrains. Unfortunately, it looks like NotNullAttribute is removed during the compilation process (or on some other stage) and it can't be observed in the runtime.
Does anyone know why does it happen? Can't find an explanation on the internet/MSDN.
Here is a test that can easily reproduce it. It fails on the second assertion.
...ANSWER
Answered 2022-Feb-16 at 15:15If you use SharpLab you can see in the lowered code that the attribute is indeed removed from the property, and instead is applied to the return parameter:

QUESTION
I am using Netbeans 12.5 and java 16
In an Java Modular Project I have 2 Modules
...ANSWER
Answered 2021-Nov-12 at 11:19You are creating a new module layer containing two modules and establishing access of one of these modules to the other. However, you actually want to establishing access for the currently running main method to one the these modules.
The currently running main method can’t be part of the new module layer it just creates. Assuming standard launcher setup, it belongs to a Controller
module loaded by the system class loader as part of the boot-layer.
So, instead of granting access to a new module of the same name in the new layer, you have to change the code to grant access to the already loaded Controller
module. Since the new Controller
module of the new module layer serves no purpose then, you can remove it from the layer configuration.
QUESTION
Similar to PropertyInfo.GetValue on Boolean is always True although no useful answer was posted.
I'm using Entity Framework to gather objects from a database and I'm trying to create Json structures as strings. However when gathering boolean answers in the same way as other types, the boolean always returns true.
I've tried to cast the value to a boolean here but I originally tried using the same method as other types (just using value). Is there a reason for this or a fix? Thanks

Answered 2022-Jan-10 at 14:04The premise of the question is incorrect; PropertyInfo.GetValue
works just fine - here used with your method with zero changes:
QUESTION
I'm converting an object based on reflection like this.
...ANSWER
Answered 2022-Jan-01 at 18:01I can't think of a solution that's significantly different to yours, fundamentally it feels like it's a custom logic to determine whether a property value is "empty" or not.
Perhaps a pattern matched switch expression might make the code a little cleaner, however, for example:
QUESTION
Given below code snippet, for each field of POJO class, is there a way to check if the type is an integer list or not? The real problem here is the type argument, since it's quite easy to check if it's a list via instanceof
or isAssignableFrom
.
Lines in main
is what I have found so far, but it does not work for those types with more complex class hierarchy.
ANSWER
Answered 2021-Nov-26 at 10:50You are right, this is not an easy problem because of erasure. However, I think it is not unsolvable.
The fundamental principle should be to follow and replace the type variables with actual parameter types all the way to List
.
Consider these two classes:

instead.
