阅读更多关于 Ripple Emulator doesn't fire events

问题 I have newest Ripple Emulator installed (newest available in Chrome Store) and everything works just fine, except events. None of them fires (not only deviceready as in some other SO question, none). Neither manually (using Events pane) nor automatically ( deviceready ) fired. When I use manual method, Ripple writes a line to the console, that it is firing an event, but nothing actually happens. My application does not react at all. I have backbutton event bind and it is not working in Ripple

Ripple effect in pressed state + transparency in normal state

阅读更多关于 Ripple effect in pressed state + transparency in normal state

问题 I would like the ImageView in the ViewGroup, when pressed, draws the ripple and this is working ! But when the ViewGroup is pressed, the ImageView inside it, should remain transparent otherwise the ImageView background is visible: (that color alpha-orange, you actually see, is the ripple when pressed). This happens only with devices API 21+. With devices API <21 I use a selector and the image background remains transparent as wanted when the ViewGroup is pressed. layout.xml <LinearLayout

区块链在金融领域的应用案例

阅读更多关于区块链在金融领域的应用案例

区块链这一颠覆性的技术作为当下多种热门概念的交集，将在可预见的未来深刻地影响包括金融业在内的多个行业，制造跨领域合作的机会，提高资源配置效率，助力产业转型升级。对区块链技术的积极应对或是被动接受，也将导致各行业内部的重新洗牌。在金融领域，区块链提供了一个全新的视野来俯瞰各类传统金融业务，区块链将成为金融领域的技术重构者、业务重构者以及金融生态重构者。案例一：布比等公司尝试区块链进行股权登记转让与清算结算目前，证券的登记、清算和结算涉及多个主体，如图4-7所示的传统股权交易过程涉及中介机构、托管机构、第三方支付平台、公证人、银行等，交易过程需要经过层层中介传递信息，再经权威机构公证方可完成。中间需要大量人工处理纸质材料信息，这样容易出错，交易效率低下且交易成本较高。因为一方面，各个机构依赖于本身的IT系统和工作流程，往往需要多方进行数据的反复沟通、核对和发送等，效率较低；另一方面，中心化的系统容易遭受攻击，对安全性投入要求非常高。图4-7　证券交易结算流程区块链的共享、可信、可追溯的特点在清算结算等领域具备显著的优势：（1）区块链是一个共享式的公共账本，可打通不同的系统，从而提升沟通效率，降低成本。（2）区块链实现交易的时候，基于区块链网络的共识机制实际上可以同时实现清算和结算，这显然比许多交易所的T+1，甚至T+N效率更高。（3

Why does including this module not override a dynamically-generated method?

阅读更多关于 Why does including this module not override a dynamically-generated method?

问题 I'm trying to override a dynamically-generated method by including a module. In the example below, a Ripple association adds a rows= method to Table. I want to call that method, but also do some additional stuff afterwards. I created a module to override the method, thinking that the module's row= would be able to call super to use the existing method. class Table # Ripple association - creates rows= method many :rows, :class_name => Table::Row # Hacky first attempt to use the dynamically
