问题 Does anybody knows how can I set margins to a custom dialog? I'm asking because I've a custom dialog but when displayed it stretches to fill the parent, even though I set explicitly WRAP_CONTENT on the layout params. Basically, the dialog contains a listview whose elements must be scrolled down, when the elements are 1 for example, it doesn't stretch, but when more items are added, then the dialog occupies the entire screen. Any suggestions? I've trying all possible combinations of possible

在项目中的用到弹窗时，一般都会用Dialog,其实可以使用Dialog样式的Activity来实现，只需要在注册Activity时指明theme就行。下面就记录一下这个Dialog的创建过程，以及一些遇到的坑。 第一步：创建一个DialogActivity,继承自Activity, 第二步：在注册清单里给这个Activity,添加主题样式theme， <activity android:name=".han.DialogActivity" android:label="@string/app_name" android:theme="@style/activityDialogTheme"> </activity> 其中的activityDialog 在res_values_styles.xml 下创建的一个dialog样式： <style name="activityDialogTheme" parent="@android:style/Theme.Dialog"> <item name="android:windowFrame">@null</item><!--边框--> <item name="android:windowIsFloating">false</item><!--是否浮现在activity之上--> <item name="android

问题 This is a very trivial problem but I can't seem to find a way of solving it. It's annoying me because I feel I should know the answer to this, but I'm either searching for the wrong terms or looking at the wrong methods and properties. I have a configuration dialog that's called from two places. The first is from the button on the form which is working correctly - as you'd expect. The second is from a context menu on the notifyIcon in the system tray, but here it appears at the top left of

Show dialog with MVVM Light toolkit

由 笑着哭i 提交于 2019-12-28 05:10:06
问题 I have a ViewModel that needs to show a modal window (using ShowDialog() ) on a button click. The ViewModel catches the click command, but I don't want to do window.ShowDialog() within my ViewModel. I know there is a DialogMessage in MVVM Light, but that is used to show message boxes, not WPF modal windows. Any ideas on how to do this? 回答1: You should use Messenger class. On the View register a message to show window and then when you need to show it call Send method of Messenger class. You

问题 I have a dialogfragment for a floating dialog which includes a special keyboard that pops up when a user presses inside an EditText field (the normal IME is stopped from being displayed). I would like the keyboard to be dismissed (visibility = GONE) when the user presses the back button (just as with a normal IME service) but the dialog to remain visible. However, there does not appear to be a way to do this as far as I can see from my fairly extensive reading on SO and elsewhere. If I set

jQuery UI dialog box not positioned center screen

问题 I have a jQuery dialog box that is meant to position in the middle of the screen. However, it seems slightly off-center vertically. Here is the code: $('#add_box').dialog({ autoOpen: true, width: 300, modal: true, resizable: false, bgiframe:true }); Any ideas why this won't center? 回答1: If your viewport gets scrolled after the dialog displays, it will no longer be centered. It's possible to unintentionally cause the viewport to scroll by adding/removing content from the page. You can recenter

Open directory dialog

问题 I want the user to select a directory where a file that I will then generate will be saved. I know that in WPF I should use the OpenFileDialog from Win32, but unfortunately the dialog requires file(s) to be selected - it stays open if I simply click OK without choosing one. I could "hack up" the functionality by letting the user pick a file and then strip the path to figure out which directory it belongs to but that's unintuitive at best. Has anyone seen this done before? 回答1: You can use the

问题 I am going to make a button to take an action and save the data into a database. Once the user clicks on the button, I want a JavaScript alert to offer “yes” and “cancel” options. If the user selects “yes”, the data will be inserted into the database, otherwise no action will be taken. How do I display such a dialog? 回答1: You’re probably looking for confirm(), which displays a prompt and returns true or false based on what the user decided: if (confirm('Are you sure you want to save this

问题 I have a splash screen on a timer. My problem is that before I finish() my activity I need to check that the next activity has started because a system dialogue box pops-up and I only want to finish() ; once the user has selected an option from the dialogue box? I know that there are many questions on how to see if your activity is in the foreground but I do not know if this allows for dialogue boxes on top of the activity too. Here is the problem, the red is my activity which is in the
