TouchableOpacity as Item in ListView only reacts after TextInput has lost focus

青春壹個敷衍的年華 提交于 2019-11-30 07:26:08
问题 I'm working on a search component right now which consists of a TextInput and a ListView. It loads its results from an external server and fills the ListView accordingly. There's also a TouchableOpacity which closes the search component. Unfortunately, it takes two presses to get the onPress callback of the TouchableOpacity called – one to let the TextInput lose its focus and one to trigger the callback. But if I press the TouchableOpacity to close the search component or if I press one of

How do you dynamically identify unknown delimiters in a data file?

我的未来我决定 提交于 2019-11-30 06:51:24
I have three input data files. Each uses a different delimiter for the data contained therein. Data file one looks like this: apples | bananas | oranges | grapes data file two looks like this: quarter, dime, nickel, penny data file three looks like this: horse cow pig chicken goat (the change in the number of columns is also intentional) The thought I had was to count the number of non-alpha characters, and presume that the highest count was the separator character. However, the files with non-space separators also have spaces before and after the separators, so the spaces win on all three

问题 Inputbox: answer:=Inputbox('a','b','c'); works good, but I'm looking for a masked one, like a password box where you only see little stars instead of the typed characters. 回答1: You can send a Windows message to the edit control created by InputBox , that will flag the edit control for password entry. Code below taken from http://www.swissdelphicenter.ch/en/showcode.php?id=1208: const InputBoxMessage = WM_USER + 200; type TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender:

问题 I'm trying to create a passcode protected screen. The screen will uses 4 numeric input as the passcode.

I am writing a keyboard replacement app for Android, and I needed the keyboard customized enough that I need to run it in an Activity, instead of keeping it in the InputMethodService class.

问题 I am trying to make a function which will execute when the value of a text input field is changed. The value of the field changes when a table cell is clicked, not on keyup , nor paste.

Any help? 回答1: This is from a comment on the jQuery documentation page: In older, pre-HTML5 browsers, "keyup" is definitely what you're looking for. In

痞子三分冷 提交于 2019-11-29 15:52:56
I want to script a click on an input box. Here is an example where the focus() should do just that, but it doesn't! Why? Code.gs: function doGet(e) { return HtmlService.createHtmlOutputFromFile('myFile'); } myFile.html: <input type="text" id="new" onchange="adding(this)"/> <div id="data"></div> <script> document.getElementById('new').focus(); function adding(a){ document.getElementById('data').innerHTML += a.value; a.value = ''; } </script> I have also tried without success putting the focus() in its own function and having a body element whose onload calls that function. What DOES work is
