How to programmatically create/initialise a Button with a custom style?

由 試著忘記壹切 提交于 2020-01-04 09:08:09
问题 I am trying to programmatically create some Buttons to add them to an existing ViewGroup. This works fine, but I am not able to init the buttons with the right style. I am aware, that it is not possible to set/change the style of view once it has been created. But all solutions I found so far say, that it should be no problem to create a view with a custom style (from a API level 11 up I think and I am using 14+): Button button = new Button (getActivity(), null, R.style.MyButtonStyle); The

Change text for multiple buttons in one operation

由 纵然是瞬间 提交于 2020-01-04 06:07:14
问题 I have a form which consist of many buttons (50+) and they all have the same name except for the suffix number. ( btn_0 , btn_1 , btn_3 , etc.) I want to change the text of those buttons in one operation. Is there a way of treating buttons like arrays? btn_[i].Text = "something"? Maybe execute a string? "btn_{0}.Text=\"something\"" 回答1: you will need to access each button at a time to do this. Do it in a loop like this foreach(var btn in this.Controls) { Button tmpbtn; try { tmpbtn = (Button)

Detect when a user moves off of a button in Android

问题 Is it possible to detect anytime a user moves their finger off of a button after they have been pressing down on it? I have determined that onTouchListener will get an action when the user moves off of the button vertically (It gives an action: ACTION_CANCEL), but I have not been able to find a way to determine when a user moves off the button horizontally. public boolean onTouch(View arg0, MotionEvent arg1) { switch(arg1.getAction()){ case MotionEvent.ACTION_CANCEL: case MotionEvent.ACTION

Set button height equal to the button width

由 社会主义新天地 提交于 2020-01-04 04:38:06
问题 I've seen this question a lot on the internet, but all solutions didn't work for me.. So this is the problem. I want a button that has 50% width of the screen (that works fine). But now I want it to have the same height the as the width. Somehow this doesn't work: Button button1 = (Button) findViewById(R.id.button1); int btnSize = button1.getLayoutParams().width; button1.setLayoutParams(new LinearLayout.LayoutParams(btnSize, btnSize)); See this for the code: Activity1.java: package nl.jesse

jQuery validation works with input type=“submit”, but not html button element. Why?

由 二次信任 提交于 2020-01-04 04:23:05
问题 Using ASP.NET, why is it that the bassistance.de jQuery validation plugin prevents form submission when using input type="submit" elements, and not html button elements? The validation fires when using an html button (type="submit") tag, but the form is still submitted. Is there a way to make the jQuery validation plugin work with html button elements? A quick example: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <script type="text/javascript"> $(document).ready(function

Prevent button from being clicked programmatically

问题 I have the following button: <input type="button" disabled onClick=document.location.href="?hash=blabla" tabindex="-1" class="btn btn-transparent btn-xs cbut0" /> Now the button is disabled and using another script to re-enable it on mouse-over event, however it seems users can still click the button programmatically by loading a simple external javascript such as: window.onload = setTimeout(function(){ $('input.btn.btn-transparent').click(); }, 10000); Is there any way to prevent this

由 ↘锁芯ラ 提交于 2020-01-03 18:42:42
问题 In my grails application there is a view with a a g:link tag - it works fine, but the visuals are kind of awkward. Therefore, I want to disguise that g:link with an ordinary button. I've tried a span class and input type="button" but this did not do the trick. Side note : I don't want a g:form with an submit action. Any help is really appreciated! 回答1: Amit Jain's answer worked but had some problems in ie 8 & 7 (looked like some kind of style overlapping error). This solution worked in all
