Can I assign a “default” OnClickListener() for an Android Activity?

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-07 11:54:41
问题 I have an Activity that, for each widget in the layout, I call setOnClickListener() to assign my OnClick() handler. In my OnClick() handler I use a switch statement to execute the desired code for each button based on the View parameter's ID. Is there a way to assign a default handler to the main view instead of having to make individual listener assignment calls for each widget in the view? ================================================ UPDATE Thanks to kcoppock's starting sample I have

问题 I want to keep executing work while a button is pressed, using Java. When the button is released, the work should stop. Something like this: Button_is_pressed() { for(int i=0;i<100;i++) { count=i; print "count" } } How might I achieve this? 回答1: One way: Add a ChangeListener to the JButton's ButtonModel In this listener check the model's isPressed() method and turn on or off a Swing Timer depending on its state. If you want a background process, then you can execute or cancel a SwingWorker in

Applying an onclick event to an element that doesn't exist on page load

由 不打扰是莪最后的温柔 提交于 2019-12-07 10:12:34
问题 I have styled a list to look like a select box and I want to fire a function when the user clicks an element in the list however the element is loaded via AJAX and hence isn't there when the page loads and I can't bind an onclick event to it onDomReady . If I had it as a normal select list I could just tag on an onChange event to the <select> field, but I obviously can't do that in my case. My HTML: <div id="main_category_field" class="fields"> <div class="cat_list"> <ul> <li class=""><a rel=

Android OnClickListener not firing in GridView (2.2 only)

由 时光总嘲笑我的痴心妄想 提交于 2019-12-07 08:30:15
问题 I have a grid view of buttons that is generated by a CursorAdapter. When the CursorAdapter is passed to the Gridview the view renders correctly however the first item in the grid does not fire the OnClickListener event. If I select another button in the grid, the event fires correctly however if I selected the first button then another button, it loads the first button action then the section button action. When testing this, it only seems to be an issue in Android 2.2 on my emulator, my 1.5

Webkit <button onclick> does not fire in certain situations

由 不羁的心 提交于 2019-12-07 06:45:34
问题 I noticed that in Webkit the <button> element does not fire the onclick event when the mouse is moved from/to child elements of the button during the click. With other words: when the mousedown and mouseup events do not happen on the same element - even if both are children of the button. The same happens when clicking/releasing on/out of the pixels of the button text . To clarify I made a testcase : http://jsfiddle.net/gx9B3/ It works fine in FireFox. Fails in Chrome 15 and QtWebkit 4.7.1 Is

javascript onclick, anonymous function

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-07 06:10:22
问题 I am a beginning javascript programmer. I am trying to create something similar to Lightbox 2, but much simpler. The only reason why I want to do it from scratch on my own is so that I can learn. However, I've been stuck on the last critical part where it displays the image. I believe the problem lies where I try to use onclick with assignment to an anonymous function: elem[i].onclick = function (){liteBoxFocus(imgSource,imgTitle); return false;}; . If you run my code and try clicking on the
