How to create context menu for RecyclerView

How do I implement context menu for RecyclerView? Apparently calling registerForContextMenu(recyclerView) doesn't work. I'm calling it from a fragment. Did anybody have any success implementing this? Prabhakar You can't directly implement these method like onClickListener , OnContextMenuListener etc. because RecycleView extends android.view.ViewGroup . So we cant directly use these method. We can implement these methods in ViewHolder adapter class. We can use context menu in RecycleView like this way: public static class ViewHolder extends RecyclerView.ViewHolder implements

Configuring jstree right-click contextmenu for different node types

阅读更多关于 Configuring jstree right-click contextmenu for different node types

问题 I've seen an example somewhere online showing how to customise the appearance of jstree's right-click context menu (using contextmenu plugin). For example, allow my users to delete "documents" but not "folders" (by hiding the "delete" option from the context menu for folders). Now I can't find that example. Can anyone point me in the right direction? The official documentation didn't really help. Edit: Since I want the default context menu with only one or two minor changes, I'd prefer to not

How do I trigger the browser context menu on an element. (As if the user right-clicked)

阅读更多关于 How do I trigger the browser context menu on an element. (As if the user right-clicked)

问题 I have the need to trigger the opening of the browser (IE, Firefox, Safari, etc) context-menu via javascript. The problem I am trying to solve, is when an overlaid element is right-clicked, the element below it shows its context menu. So if the top element is a label, when you right click, I need to show the context menu for the input element below. I know how to keep the label's context menu from showing, but I don't know how to open a context menu arbitrarily. Any help is appreciated! 回答1:

lambda in for loop only takes last value

阅读更多关于 lambda in for loop only takes last value

Problemset: Context Menu should show filter variables dynamically and execute a function with parameters defined inside the callback. Generic descriptions show properly, but function call is always executed with last set option. What I have tried: #!/usr/bin/env python import Tkinter as tk import ttk from TkTreectrl import MultiListbox class SomeClass(ttk.Frame): def __init__(self, *args, **kwargs): ttk.Frame.__init__(self, *args, **kwargs) self.pack(expand=True, fill=tk.BOTH) self.grid_rowconfigure(0, weight=1) self.grid_columnconfigure(0, weight=1) self.View=MultiListbox(self) __columns=(

EditText: Disable Paste/Replace menu pop-up on Text Selection Handler click event

阅读更多关于 EditText: Disable Paste/Replace menu pop-up on Text Selection Handler click event

My goal is to have an EditText that has no fancy features, just the Text Selection Handler for moving the cursor more easily -- so no context menus or pop-ups. I've disabled the appearance of the text editing function actionbar (copy/Paste etc.) by consuming the ActionMode Callback event, as per this solution . The middle Middle Text Select Handle (see image below) still appears when text exists in the field and a click occurs within the text. Great! I want to keep this behaviour. What I DON'T want is the "PASTE" menu to appear when the Text Select Handle itself is clicked. I have also

Android: How to enable/disable option menu item on button click?

阅读更多关于 Android: How to enable/disable option menu item on button click?

问题 I can easily do it when I am using onCreateOptionsMenu or onOptionsItemSelected methods. But I have a button somewhere in screen, and on clicking that button, it should enable/disable context menu items. 回答1: Anyway, the documentation covers all the things. Changing menu items at runtime Once the activity is created, the onCreateOptionsMenu() method is called only once, as described above. The system keeps and re-uses the Menu you define in this method until your activity is destroyed. If you

Showing context menu buttons only when right-clicked on classes that start with “Story”

阅读更多关于 Showing context menu buttons only when right-clicked on classes that start with “Story”

问题 Is there a way to show context menu actions, only when the user right-clicks on classes that start with "story". For example: if the user right-clicks on an object in the page of class "story ....", the context menu buttons should appear, otherwise nothing should happen. Here is my code (though it does not work): var divs = document.querySelectorAll("[class^=story]"); //get all classes that start with "Story" window.oncontextmenu = function() { for(var i=0; i < divs.length; i++) { divs[i]
