listview

问题 I used a tutorial about listview parsing xm from internet and using LasyAdapter shows the items in listview. When I add persian characters in xml (into one of childnodes) the result is some boxes in listview (after showing the text in listview). The format of xml is UTF-8, too. I used typeface too (but didn't work). Besides when I type Pwesian into the application it shows alright but it can't show Persiann content parsed from xml. Thanks in advance. I updated the post with original XMLparser

问题 Good day guys. I am currently creating a some kind of advertisement app. It is simple text scrolling from top to bottom and will repeat again. I am currently using listview to do this in c#. The texts that will show in the listview will be coming from a database. I am using the timer to automatically refresh the form. The problem is how can I move it or scroll it from top to bottom automatically every time the form loads and will repeat again every time it finished. Thank you. This is the

问题 I'm having a vertical list view which has in its item template another list view in horizontal position, now everything works fine, but I want to be able to scroll all of these sub list views if one of them scrolled. Here is an illustration: Now I want all the sub list views in all rows to scroll together. How can I do this?! Maybe I can make an extending class for the list view with bindable property for scrolling ?! Something like this: public class ScrollableListView : ListView { public

问题 I'm trying to make countdowns to date and put each countdown in an ItemView in a ListView. I have already the Listview.buillder() but I don't know how to make countdowns which have different values and put them in the Listview. I have seen that there is another similar question but I can't solve my problem with it. Here is my code : home_screen.dart import 'package:flutter/material.dart'; import 'package:cached_network_image/cached_network_image.dart'; import '../recyclerview/data.dart';

问题 I have a ListView with some Labels in it. The labels' width property is bound to the width property of the ListView but they seem to be slightly larger meaning that a horizontal scrollbar is shown on the list view. What I want is to fit the labels in the list view without the scrollbar on the bottom. I have looked at various padding and insets values on both the label and the list view but none I have found are the culprit (most are zero). Here is an example which demonstrates the problem.

问题 Not sure what hasn't been initialised here, I'm guessing I have to manually create a new row on the list itself but I have no clue how to even start on that. Here is the code I use to create and call the adapter: /** * Retrieve adapter UI * * @param position current position with the list * @param convertView view * @param parent container * @return view, UI elements */ @Override public View getView(final int position, final View convertView, final ViewGroup parent) { final ViewHolder handler

问题 I have an online JSON file that shows the latest country earthquakes, the listView adapter in my app receives data from this JSON file and the refresh is manually by user`s swipe, but now I am adding an automatic and timely basis refresh mode to my list, the questions is: How can I create a system notification after a new quake is detected? 回答1: Write this below code for sending System notification in your app while your data is loaded from network request. Intent intent = new Intent

问题 I'm doing some research and I would like to know how I can implement a column filter in a ListView using purely win32 api. Something like this: I wrote a simple test code, to generate a List View to show the CSV content. #include <windows.h> #include <stdio.h> #include <stdlib.h> #include <commctrl.h> #include <string.h> #define WND_CLASS_NAME "CSVVIEW" char* filename; HWND hList; int rgb(int r, int g, int b) { return r + (g << 8) + (b << 16); } void onCreate(HWND hWnd, LPARAM lParam) {
