Please help. What am I doing wrong. Thanks. The code is as follows. I have buttons and textviews inside the runnable. public class TodayFragment extends Fragment { //initialisations @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { //UI initialisations

问题 I have a recyclerview . I want to achieve one functionality, but I can't implement it. My RecyclerView item has 2 textView and a button . public class Task { private String id; private String title; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } } So let me explain a little. The button in my recyclerView item uses stateListDrawable , so it becomes active

Why main thread's Looper.loop() doesn't block UI thread?

问题 Today I read some blogs and source code about how Handler & Looper work together. Based on what I've learnt, we can have only one Looper on each thread by using the ThreadLocal magic. Usually Handler is initiated in main thread, or else you must manually start or saying, prepare the Looper on a separate thread and then loop it up. class LooperThread extends Thread { public Handler mHandler; public void run() { Looper.prepare(); mHandler = new Handler() { public void handleMessage(Message msg)

How to pass templated variables to server-side handler functions in HTML files using Google Apps Script?

问题 Follow up to this answer. https://stackoverflow.com/a/60073413/1640892 I want to pass a templated object variable to a server side function in GAS. I expect to see the buttons render, then after filling out the payment details and clicking pay, I expect to see the handleTxn() function successfully execute using the content object as one of its arguments. But, instead, nothing happens because the buttons do not even render. It fails silently. var content = <?!= content ?>; google.script.run

【PHP源码】PHP 函数调用

≡放荡痞女 提交于 2020-04-07 20:46:29
想法 我以前对于 C 语言的印象是有很强的确定性,而 PHP 在执行的时候会被翻译为 C 语言执行,所以一直很好奇 PHP 怎么调用底层函数。 换句话说就是已知函数名字的情况下如何调用 C 语言中对应名字的函数? 解决这个问题前,首先根据过往的经验做出假设,然后再去验证。 之前在写《用 C 语言实现面向对象》的时候,就意识到使用 void 指针实现很多功能,包括指向任意的函数。接着在写《PHP 数组底层实现》的时候,了解了 HashTable 的实现,即在 C 语言层面通过字符串 key 找到任意类型值。 现在把两者结合起来,是否就能解决以上问题了?比如说把函数名作为 HashTable 的 key,函数指针作为 HashTable 的 value,这样就可以通过函数名获取函数指针来调用函数了。 接下来通过查看 PHP 的源码来看这个假设与真实情况有多少差距。 总体分为三个步骤: 从 PHP 层进入 C 语言层 找到字符串函数名与函数的关系 函数的调用 注:这篇博客的源码对应的版本是 PHP 7.4.4 。 https://github.com/php/php-src/tree/php-7.4.4 从 PHP 层进入 C 语言层 首先要找到 C 语言层调用函数的地方。怎么找? 经常使用 PHP 的同学看到前面的问题描述很容易联想到 PHP
