问题 I am using a searchview in android app ( searchview is not a part of action bar ). I want to remove the space on the left side of the search icon/ searchview. I searched a lot and received answers which worked for searchviews which are part of action bar. I tried using android:layout_gravity, android:gravity , but they didnt seem to work. I thought of using android:contentInsetStart, android:contentInsetLeft , but these options are not available for searchview (which is not a part of action

Padding strings that contain accents

由 蹲街弑〆低调 提交于 2019-12-10 11:53:55
问题 I'm padding a string that contains accents in it. However, the final string length is larger due to the accents that it contains. I guess it has to do with ASCII / Unicode differences, but I haven't figured out the exact reason. I already tried: myString = "San José del Cabo"; myString.PadRight(' ', 20); and myString = "San José del Cabo"; string.format("{0,-20}", myString); And the actual result is 21 characters long. Is there a builtin method in C# that takes into account the string

how to get the size of the padding at the end of a class

由 感情迁移 提交于 2019-12-10 11:44:24
问题 I have a class A like this: struct V { virtual void f() = 0; }; struct A { int data; }; struct B : public A , public V { void f() override {} }; MSVC gives me sizeof(A) == 4 and sizeof(B) == 16 on a 64 bit build instead of 12 ( sizeof(void*) + sizeof(A) ) - so there is a 4 byte padding. Is there a way to get that padding? perhaps with some trait? The reason I need this is to do an assert like this: static_assert(sizeof(B) == sizeof(A) + std::is_polymorphic<camera>::value * sizeof(void*));

Ensure padding around markers on Google Maps for web [duplicate]

问题 This question already has answers here : Google Maps API 3 fitBounds padding - ensure markers are not obscured by overlaid controls (7 answers) Closed 3 years ago . I have a full screen Google map with HTML/CSS toolbars overlaid on the map, and a set of map markers. Is there a way to ensure there is enough padding between the markers and the edges of the map, so that no markers are obscured by the toolbars? (Codepen in case the code below doesn't work) function initMap() { var map = new

Margin/Padding Shrinks ImageView

问题 I recently tried to position an imageview's x and y coordinates with no luck, it seems there is no way to do it in Gingerbread. I then decided to try out paddings and margins, but when I set them, it shrinks my imageview. I set a left padding of 250dp and image view became tiny. The layout_height and width are set to wrap_content. I'm not sure what's going on. Does anyone know why setting a padding/margin would shrink an imageview? 回答1: You're confusing margin and padding. Margin is the area

Element UI - 打开弹出框（el-dialog）页面会抖动

由 自古美人都是妖i 提交于 2019-12-10 11:19:49
当 dialog 出现时，页面右边缩小了 5px，模态框看起来会抖动 解决方案 发现 body 多了样式：padding-right: 5px 和 overflow: hidden。紧接着我就在全局设置 body 的 padding-right: 0 !important 就好了~ 本文转载自： https://blog.csdn.net/Dream_Weave/article/details/95041203 来源： https://www.cnblogs.com/smart-girl/p/12015509.html

tensorflow学习笔记——AlexNet

由 帅比萌擦擦* 提交于 2019-12-10 10:51:54
1，AlexNet网络的创新点 　　AlexNet将LeNet的思想发扬光大，把CNN的基本原理应用到了很深很宽的网络中。AlexNet主要使用到的新技术点如下： 　　 （1）成功使用ReLU作为CNN的激活函数，并验证其效果在较深的网络超过了Sigmoid，成功解决了Sigmoid在网络较深时的梯度弥散问题。虽然ReLU激活函数在很久之前就被提出了，但直到AlexNet的出现才将其发扬光大。 　　在最初的感知机模型中，输入和输出的关系如下： 　　虽然只是单纯的线性关系，这样的网络结构有很大的局限性：即使用很多这样结构的网络层叠加，其输出和输入仍然是线性关系，无法处理有非线性关系的输入输出。因此，对每个神经元的输出做个非线性的转换也就是，将上面的加权求和的结果输入到一个非线性函数，也就是激活函数中。这样，由于激活函数的引入，多个网络层的叠加就不再是单纯的线性变换，而是具有更强的表现能力。 　　在网络层较少时，Sigmoid函数的特性能够很好的满足激活函数的作用：它把一个实数压缩至0到1之间，当输入的数字非常大的时候，结果会接近1,；当输入非常大的负数时，则会得到接近0的结果。这种特性，能够很好的模拟神经元在受刺激后，是否被激活向后传递信息（输出为0,几乎不被激活；输出为1，完全被激活）。Sigmoid函数一个很大的问题就是梯度饱和。观察Sigmoid函数的曲线，当输入的数字较大

Pad list in Python

由 你说的曾经没有我的故事 提交于 2019-12-10 05:17:19
问题 How can I pad a list when printed in python? For example, I have the following list: mylist = ['foo', 'bar'] I want to print this padded to four indices, with commas. I know I can do the following to get it as a comma and space separated list: ', '.join(mylist) But how can I pad it to four indices with 'x's, so the output is like: foo, bar, x, x 回答1: In [1]: l = ['foo', 'bar'] In [2]: ', '.join(l + ['x'] * (4 - len(l))) Out[2]: 'foo, bar, x, x' The ['x'] * (4 - len(l)) produces a list

水平居中和垂直居中

1.水平居中 (1) 文本、图片等行内元素的水平居中 　　给父元素设置text-align:center可以实现文本、图片等行内元素的水平居中。 (2) 确定宽度的块级元素的水平居中 　　通过设置margin-left:auto;和margin-right:auto;来实现的。 (3) 不确定宽度的块级元素的水平居中 　　方法一: 　　使用table标签，table本身并不是块级元素，如果不给它设定宽度的话，它的宽度由内部元素的宽度“撑起”，但即使不设定它的宽度，仅设置margin-left:auto;和margin-right:auto;就可以实现水平居中! 　　将需要居中的部分包含在table标签内，对table设置margin-left:auto;和margin-right:auto;就可以使table水平居中，间接使需要居中的部分水平居中。 　　缺点：增加了无语意标签，加深了标签的嵌套层数。 <style type="text/css">ul{list-style:none; margin:0; padding:0;}.wrap{ width:500px; height:100px;}table{margin-left:auto;margin-right:auto;}.test li{float:left; display:inline; margin-right:5px;
