工作中会遇到各种各样的问题,ReactNative开发也是填坑不止。 比如最近在开发需求中,就遇到一个问题。在一个卡片类型的右上角添加一个删除按钮。使用了绝对布局position:'absolute’属性,在Android上却无法正常显示,很是烦恼。 有一个相关的issue:https://github.com/facebook/react-native/issues/27255 正常希望的展示效果: 但是实际效果是: 可以看到,绿色的view被遮挡了。 查阅相关资料和尝试之后,可以使用position:‘absolute’ 和zIndex结合使用解决这个问题。 最后贴一下,相关代码。 <View style={{ position: 'absolute', zIndex: 99999, justifyContent: 'center', alignItems: 'center', top: 10, width: 30, height: 30, elevation: 99999 }}> <Image source={require('images/compared/delete_gray.png')} /> </View> 个人网站: https://wayne214.github.io, 微信公众号:君伟说。 来源: CSDN 作者: wayne214 链接: https:/

1、由于recycleview复用机制,checkbox选一个,下面自动选中,edittext自动输入问题: @Override public void onBindViewHolder(ViewHolder viewHolder, int position) { //禁止复用,要不数据重复 viewHolder.setIsRecyclable(false); viewHolder.ckPeoplewater.setText(chargeList.get(position).getItem_Name()); viewHolder.tvPeopleprice.setText(chargeList.get(position).getItem_Price()+""); viewHolder.tvPeopleprice1.setText(chargeList.get(position).getSewageFee()+""); viewHolder.tvPeopleprice2.setText(chargeList.get(position).getResourceFee()+""); viewHolder.etPeoplewater.setText(chargeList.get(position).getItemHighLimit()+""); viewHolder

Python爬虫实战(7)Selenium+拉勾网 网页分析 首页 列表页 详情页 代码 注意事项 0.关闭完切换城市后不能马上输入 1.是否还有下一页的判断 2.模拟打开新网页时,网页的输入 3.文本的对齐 输出结果 利用selenium和BeautifulSoup库爬取拉勾网的职位信息。 运行平台: Windows Python版本: Python 3.8 IDE: Pycharm 基本思路:打开网页在输入框输入搜索信息,再点击搜索,在网页源码中得到各个职位信息的href。再利用各个href打开职位信息的详情页,爬取信息。 网页分析 首页 打开首页会跳出切换城市的界面,找到关闭界面的id,点击关闭它。 然后依次找到输入框,输入内容,再点击搜索。 列表页 各个职位的href都放在 class=“position_link” 这个标签中。找到这些职位的href即可。 详情页 职位的名称在 class=“name” 中,其他信息在 class=“job_request” 的各个span标签下。 代码 # 利用selenium爬取拉勾网信息 import time from selenium import webdriver from bs4 import BeautifulSoup class Lagou_spider ( object ) : driver_path = r 'E:

Fixed position footer at 100% width extends past window to right

守給你的承諾、 提交于 2019-12-14 04:03:39
问题 I need help with trying to get this footer set in a fixed position. I'm learning as I go and trying to make a reasonably liquid layout. It's a work-in-progress but I can't continue until I get the footer in the right place. My problem is it keeps extending past the window to the right. Sometimes it creates a scrollbar and does not follow margin rules. I've tried just about everything I could think of and what I could find by using trusty google. I have used the latest chrome and firefox

Is the CSS right?

*爱你&永不变心* 提交于 2019-12-14 03:29:02
问题 Below is my CSS file and an image of what I'm referencing. In the picture, it's the 1st, but if it was the 10th, or any other 2-digit-day, would the 2013 or no? It's a dumb question, and I know, but I'm not sure about the whole margin, padding, position, and float factors. REPHRASED QUESTION: I'm not too good with padding and margins so maybe I'm asking the wrong question. The picture shows April 1 2013, great. But I'm wondering if April 10 (a 2nd-digit day) will make the 2013 shift RIGHT
