I creat a custom advancedatagridgroupitemrenderer which using HierarchicalData as my dataprovide ;
my itemrenderer like this:
public class XwjsjglAdvancedDgGroupItemRenderer extends AdvancedDataGridGroupItemRenderer{
public function XwjsjglAdvancedDgGroupItemRenderer()
{
super();
}
override public function set data(v:Object):void{
super.data = v;
}
protected var img:Image;
override protected function createChildren():void{
super.createChildren();
img= new Image();
img.source="/assets/images/indexNow/jsjhc.png";
this.addChild(DisplayObject(img));
}
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth,unscaledHeight);
img.x = label.x + 2;
img.y = label.y + 2;
label.x = img.x + 70;
}
override protected function commitProperties():void
{
super.commitProperties();
}
override protected function measure():void
{
super.measure();
measuredWidth += 90;
measuredHeight+= 90;
}
}
and the runing effect is this:

how can i do ?Any help with this issue would be greatly appreciated.

I am making a 2D game in Unity and am trying to make my moveable character stop every time dialogue appears on screen.
I am using the Fungus extension for my dialogue as I'm a newbie to coding. Every thing I try however I run in to problems.
My current issue is that the modifier 'public' is not valid for this item.
Anyone know how this can be fixed? I have attached the code below. I assume the issue is with the public void CantMove() and public void CanMove() lines.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerController : MonoBehaviour
{
public float moveSpeed;
public Rigidbody2D theRB;
public float jumpForce;
private bool isGrounded;
public Transform groundCheckPoint;
public LayerMask whatIsGround;
private bool canDoubleJump;
private bool canMove = true;
private Animator anim;
private SpriteRenderer theSR;
// Start is called before the first frame update
void Start()
{
anim = GetComponent<Animator>();
theSR = GetComponent<SpriteRenderer>();
}
// Update is called once per frame
void Update()
{
if(!canMove)
{
theRB.velocity = new Vector2(0, 0);
}
else
{
theRB.velocity = new Vector2(moveSpeed * Input.GetAxis("Horizontal"), theRB.velocity.y);
}
public void CantMove()
{
canMove = false;
}
public void CanMove()
{
canMove = true;
}
//theRB.velocity = new Vector2(moveSpeed * Input.GetAxis("Horizontal"), theRB.velocity.y);
isGrounded = Physics2D.OverlapCircle(groundCheckPoint.position, .2f, whatIsGround);
if(isGrounded)
{
canDoubleJump = true;
}
if(Input.GetButtonDown("Jump"))
{
if (isGrounded)
{
theRB.velocity = new Vector2(theRB.velocity.x, jumpForce);
}
else
{
if(canDoubleJump)
{
theRB.velocity = new Vector2(theRB.velocity.x, jumpForce);
canDoubleJump = false;
}
}
}
if(theRB.velocity.x > 0)
{
theSR.flipX = true;
} else if(theRB.velocity.x < 0)
{
theSR.flipX = false;
}
anim.SetFloat("moveSpeed", Mathf.Abs( theRB.velocity.x));
anim.SetBool("isGrounded", isGrounded);
}
}
'''
Your problem is that your two functions defined for CanMove and CantMove are declared inside of the Update function body... which makes them locally scoped functions which means they can never have public access and can only be called from within the Update function itself.
Move these two functions outside of the Update function body like this...
void Update() {
...
}
public void CantMove() {
canMove = false;
}
public void CanMove() {
canMove = true;
}
For the first time I'm restricting the onAppearing() methods in all child pages of tabbed page. I need to call the onAppearing() when I change the tab. For that, I'm using OnCurrentPageChanged() to call the onAppearing() method.
When I change the tab, I'm calling the OnCurrentPageChanged() and giving them access to run the onAppearing() functionality. onAppearing() is calling before calling the OnCurrentPageChanged().
TabbedPage code:
public partial class VendorScheduleTabbedPage : Xamarin.Forms.TabbedPage
{
public int isCount;
public VendorScheduleTabbedPage ()
{
InitializeComponent ();
Xamarin.Forms.Application.Current.Properties["dayOnAppear"] = false;
Xamarin.Forms.Application.Current.Properties["weekOnAppear"] = false;
Xamarin.Forms.Application.Current.Properties["monthOnAppear"] = false;
On<Android>().SetBarItemColor(value: Color.FromHex("#6699FF"));
On<Android>().SetBarSelectedItemColor(value: Color.Orange);
}
override protected void OnCurrentPageChanged()
{
isCount = 1;
if (this.CurrentPage.Title == "Week")
{
Xamarin.Forms.Application.Current.Properties["weekOnAppear"] = true;
}
if (this.CurrentPage.Title == "Month")
{
Xamarin.Forms.Application.Current.Properties["monthOnAppear"] = true;
}
else
{
Xamarin.Forms.Application.Current.Properties["dayOnAppear"] = true;
}
base.OnCurrentPageChanged();
}
}
}
Week Page code(child page):
public WeekSchedulePage()
{
InitializeComponent();
NavigationPage.SetHasNavigationBar(this, false);
timeSlot = new List<VendorScheduleTimeSlot>();
scheduleSlots = new List<VendorScheduleTimeSlot>();
lstVendorsData = new List<ScheduledCustomersVM>();
SortedList = new List<ScheduledCustomersVM>();
scheduledCustomersList = new List<ScheduledCustomersVM>();
rescheduledCustomersList = new List<RescheduledCustomersVM>();
ConfirmBtn.IsVisible = true;
ConfirmBtn.IsEnabled = false;
vendorDayAndHoursDataVM = new VendorDayAndHoursDataVM();
lstDaysAndHours = new List<VendorDayAndHoursDataVM>();
lstQuestionsData = new List<VendorQuestionsDataVM>();
overlay.IsVisible = false;
Alert.IsVisible = false;
presentWeekDay.Text = DateTime.Now.ToString("dddd, dd MMMM yyyy");
currentDayName = DateTime.Now.DayOfWeek.ToString();
currentDate = DateTime.Parse(presentWeekDay.Text);
}
protected override void OnAppearing()
{
var isAppear = Convert.ToBoolean(Application.Current.Properties["weekOnAppear"].ToString());
if (isAppear == true)
{
ConfirmBtn.IsVisible = true;
ConfirmBtn.IsEnabled = false;
overlay.IsVisible = false;
Alert.IsVisible = false;
Application.Current.Properties["dayOnAppear"] = true;
Application.Current.Properties["monthOnAppear"] = true;
ConfirmBtn.IsEnabled = false;
scheduledCustomersList.Clear();
rescheduledCustomersList.Clear();
presentWeekDay.Text = DateTime.Now.ToString("dddd, dd MMMM yyyy");
currentDayName = DateTime.Now.DayOfWeek.ToString();
weekwiseTimeslotClick();
base.OnAppearing();
}
}
Here I need to call OnCurrentPageChanged() method first instead of the OnApearing() method. And OnCurrentPageChanged() will give the bool value to perform the code which is in OnApearing() method.
In Android, onAppearing is called before OnCurrentPageChanged while in iOS OnCurrentPageChanged is called before onAppearing.
1.As jgoldberger suggested, you can call method in each Page after CurrentPageChanged:
override protected void OnCurrentPageChanged()
{
if (this.CurrentPage.Title == "Week")
{
Xamarin.Forms.Application.Current.Properties["weekOnAppear"] = true;
NavigationPage naviPage = this.Children[0] as NavigationPage;
WeekPage page = naviPage.RootPage as WeekPage;
page.test();
}else if (this.CurrentPage.Title == "Month")
{
Xamarin.Forms.Application.Current.Properties["monthOnAppear"] = true;
NavigationPage naviPage = this.Children[1] as NavigationPage;
MonthPage page = naviPage.RootPage as MonthPage;
page.test();
}
else
{
Xamarin.Forms.Application.Current.Properties["dayOnAppear"] = true;
NavigationPage naviPage = this.Children[2] as NavigationPage;
DayPage page = naviPage.RootPage as DayPage;
page.test();
}
base.OnCurrentPageChanged();
}
}
2.You can use messaging-center to notify specific page to perform some actions after CurrentPageChanged:
override protected void OnCurrentPageChanged()
{
string testStr;
if (this.CurrentPage.Title == "Week")
{
testStr = "Week";
}else if (this.CurrentPage.Title == "Month")
{
testStr = "Month";
}
else
{
testStr = "Day";
}
MessagingCenter.Send<object, string>(new object(), "CurrentPageChanged", testStr);
base.OnCurrentPageChanged();
}
And in each page:
public partial class MonthPage : ContentPage
{
public MonthPage()
{
InitializeComponent();
MessagingCenter.Subscribe<object, string>(new object(), "CurrentPageChanged", async (sender, arg) =>
{
if (arg == "Month")
{
Console.WriteLine(arg);
//do something
}
});
}
public void test() {
Console.WriteLine("test");
//do something
}
}
BTW, you should use if...else if...else instead of if...if...else in your control statement.
I create a custom control for UILabel with custom Kern parameter.
[Register("CustomLabelView"), DesignTimeVisible(true)]
public class CustomLabelView : UILabel
{
private float _textLetterSpacing;
public CustomLabelView(IntPtr handle) : base(handle)
{
}
[Export("TextLetterSpacing"), Browsable(true)]
public float TextLetterSpacing
{
get => _textLetterSpacing;
set
{
_textLetterSpacing = value;
SetNeedsDisplay();
}
}
public CustomLabelView()
{
Initialize();
}
public override void AwakeFromNib()
{
// Called when loaded from xib or storyboard.
Initialize();
}
void Initialize()
{
NSRange range = new NSRange(0, Text.Length);
var attributes = AttributedText.GetCoreTextAttributes(0, out range);
var attributedTitle = new NSAttributedString(Text, new CTStringAttributes() { KerningAdjustment = TextLetterSpacing, ForegroundColor = TextColor.CGColor, UnderlineStyle = attributes.UnderlineStyle });
AttributedText = attributedTitle;
SetNeedsDisplay();
}
}
I bind text to this control with language converter
set.Bind(CustomLabelView)
.For(c => c.Text)
.To(vm => vm.TextSource)
.WithConversion("Language", "AgreementText");
and underline property doesn't apply for bound text. Also I tried AttributedText property instead of Text. No any changes.
My LinkerPleaseInclude file contains this lines
public void Include(UILabel label)
{
label.Text = label.Text + "";
label.AttributedText = new NSAttributedString(label.AttributedText.ToString() + "");
}
Any ideas how to sort it out?
I changed the UnderlineStyle property's value to one of the enumeration of CTUnderlineStyle and it works for me.
namespace CoreText
{
//
// Summary:
// Specifies the style of an underline ornament.
//
// Remarks:
// To be added.
public enum CTUnderlineStyle
{
None = 0,
Single = 1,
Thick = 2,
Double = 9
}
}
Here is my code:
void Initialize()
{
this.Text = "This is some formatted text";
NSRange range = new NSRange(0, Text.Length);
var attributes = AttributedText.GetCoreTextAttributes(0, out range);
var attributedTitle = new NSAttributedString(Text, new CTStringAttributes() { KerningAdjustment = TextLetterSpacing, ForegroundColor = TextColor.CGColor, UnderlineStyle = CTUnderlineStyle.Single });
AttributedText = attributedTitle;
SetNeedsDisplay();
}
The underline appears,is this you want?
I just put Initialize method into Draw for my CustomLabel.
Here is the solution:
public override void Draw(CGRect rect)
{
Initialize();
base.Draw(rect);
}
private void Initialize()
{
var attributes = AttributedText.GetCoreTextAttributes(0, out _);
AttributedText = new NSMutableAttributedString(Text,
new CTStringAttributes
{
KerningAdjustment = TextLetterSpacing, Font = attributes.Font,
UnderlineStyle = attributes.UnderlineStyle
});
}
I'm not able to override GetChildrenCore correctly. I use this for a Canvas to get information about it's children (Line, Rectangle).
The output correctly indicates the first child but misses the second. Even though the Canvas already contains both.
Custom Canvas
Custom Line Childs of Canvas parent: 2
Instead it should be like this:
Custom Canvas
Custom Line Childs of Canvas parent: 2
Custom Rectangle Childs of Canvas parent: 2
App side side:
public class ElementAP : FrameworkElementAutomationPeer
{
private FrameworkElement Owner = null;
private Int32 Count = 0;
public ElementAP(FrameworkElement owner, Int32 count) : base (owner)
{
Owner = owner;
Count = count;
}
protected override AutomationControlType GetAutomationControlTypeCore()
{
return AutomationControlType.Custom;
}
protected override string GetClassNameCore()
{
return $"{Owner.GetType().Name} Childs of Canvas parent: {Count}";
}
}
public class CanvasAP : FrameworkElementAutomationPeer
{
public CanvasAP(Windows.UI.Xaml.Controls.Canvas owner) : base(owner)
{
}
protected override AutomationControlType GetAutomationControlTypeCore()
{
return AutomationControlType.Custom;
}
protected override string GetClassNameCore()
{
return "Canvas";
}
protected override IList<AutomationPeer> GetChildrenCore()
{
var owner = (Windows.UI.Xaml.Controls.Canvas)Owner;
var list = new List<AutomationPeer> ();
foreach (var child in owner.Children)
{
var peer = new ElementAP(child as FrameworkElement, owner.Children.Count);
list.Add(peer);
}
return list;
}
}
UI Testing side:
private static string WalkTree(UITestControl element, Int32 level = 0)
{
var children = element.GetChildren();
var str = "";
foreach (var c in children)
{
str += GetElementString(c, level);
str += WalkTree(c, level + 1);
}
return str;
}
private static string GetElementString(UITestControl element, Int32 level = 0)
{
var xaml = element as XamlControl;
var str = "";
for (var i = 0; i < level; i++)
str += " ";
str += $"{element.ControlType} {element.ClassName} {element.Name} {xaml?.AutomationId ?? ""}\n";
return str;
}
I finally found an answer. When using a cache for the children`s AutomationPeers it works perfectly.
public class ElementAP : FrameworkElementAutomationPeer
{
public UIElement Element { get { return Owner; } }
public ElementAP(FrameworkElement owner) : base(owner)
{
}
protected override AutomationControlType GetAutomationControlTypeCore()
{
return AutomationControlType.Custom;
}
protected override string GetClassNameCore()
{
return Owner.GetType().Name;
}
}
public class CanvasAP : FrameworkElementAutomationPeer
{
private List<ElementAP> _cachedAutomationPeers = new List<ElementAP>();
public CanvasAP(Windows.UI.Xaml.Controls.Canvas owner) : base(owner)
{
}
protected override AutomationControlType GetAutomationControlTypeCore()
{
return AutomationControlType.Custom;
}
protected override string GetClassNameCore()
{
return "Canvas";
}
protected override IList<AutomationPeer> GetChildrenCore()
{
var owner = (Windows.UI.Xaml.Controls.Canvas)Owner;
if (owner.Children.All(c => c is CanvasA))
return base.GetChildrenCore();
var list = new List<ElementAP>();
foreach (var child in owner.Children)
{
var peer = _cachedAutomationPeers.FirstOrDefault(p => p.Element == child) ?? new ElementAP(child as FrameworkElement);
list.Add(peer);
}
_cachedAutomationPeers = list;
return list.Cast<AutomationPeer>().ToList();
}
}
i got a java project about floating view from web. i try to translate it to monodroid, but i fail, because on function ,i don't know how to write in monodroid .
java code is in http://www.xsmile.net/file/FloatViewDemo.rar
namespace MonoFloatView
{
[Activity(Label = "MonoFloatView", MainLauncher = true, Icon = "#drawable/icon")]
public class MyFloatViewActivity : Activity
{
private IWindowManager wm = null;
private WindowManagerLayoutParams wmParams = null;
private MyFloatView myFV = null;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
createView();
// Create your application here
}
private void createView()
{
//myFV = new MyFloatView(getApplicationContext()); //java
myFV = new MyFloatView(ApplicationContext);
myFV.SetImageResource(Resource.Drawable.Icon);
//wm = (WindowManager)getApplicationContext().getSystemService("window");
//http://stackoverflow.com/questions/13634835/monodroid-screen-dimensions
//i get some tip from url above.
wm = GetSystemService(Activity.WindowService).JavaCast<IWindowManager>();
//i don't know the getApplication, how to write in monodroid?
wmParams = ((MyApplication)getApplication()).getMywmParams();
wmParams.Type = LayoutParams.TYPE_PHONE;
wmParams.Format = PixelFormat.RGBA_8888;
wmParams.Flags = LayoutParams.FLAG_NOT_TOUCH_MODAL
| LayoutParams.FLAG_NOT_FOCUSABLE;
wmParams.Gravity = Gravity.LEFT | Gravity.TOP;
wmParams.X = 0;
wmParams.Y = 0;
wmParams.Width = 40;
wmParams.Height = 40;
wm.AddView(myFV, wmParams);
}
public override void onDestroy()
{
base.OnDestroy();
wm.RemoveView(myFV);
}
}
}
If you're in an Activity, you should be able to use:
this.Application
