I have shown on a 10-key layout dynamically created, now I need to retrieve the ID of the button pressed to release the necessary procedure. Here the code.
Button Btn;
Toast msg;
RelativeLayout rl;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.main);
LinearLayout ll = (LinearLayout) findViewById(R.id.ll);
Btn = (Button) findViewById( R.id.Btntu );
for (int i = 0; i < 10; i++) {
Btn = new Button(this);
Btn.setText("Número: " + i);
Btn.setGravity(Gravity.CENTER);
Btn.setId(i);
rl = new RelativeLayout(this);
RelativeLayout.LayoutParams parametros = new RelativeLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
Btn.setLayoutParams(parametros);
rl.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT)
);
rl.addView(Btn);
ll.addView(rl);
}
I need the function to retrieve the ID of the button pressed.
Thank you all.
:o)
Have you tried getId() ?
http://developer.android.com/reference/android/view/View.html#getId%28%29
for (int i = 0; i < 10; i++) {
Btn = new Button(this);
Btn.setText("Número: " + i);
Btn.setGravity(Gravity.CENTER);
Btn.setId(i);
Btn.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
Log.d("Button", "ID clicked: " + Btn.getId());
// Or even
Log.d("View", "ID clicked: " + v.getId());
}
});
(...)

I'm using Xamarin.Forms.Map and I want to show pins on my map with already expanded window message(without click on them). Something like screenshot. By default window message show only after I clicked on them. How can I do this?
I did a test based on this sample：sample
The thing I do is override the GetViewForAnnotation method.
I add a subview and set it's position based on pin's position.
Here is relative code:
[assembly:ExportRenderer(typeof(CustomMap),typeof(CustomMapRenderer))]
namespace My_Forms_Test3.iOS
{
public class CustomMapRenderer:MapRenderer
{
UIView customPinView;
List<CustomPin> customPins;
protected override void OnElementChanged(ElementChangedEventArgs<View> e)
{
base.OnElementChanged(e);
if (e.OldElement != null)
{
var nativeMap = Control as MKMapView;
nativeMap.GetViewForAnnotation = null;
nativeMap.CalloutAccessoryControlTapped -= OnCallourAccessoryControlTapped;
nativeMap.DidSelectAnnotationView -= OnDidSelect;
nativeMap.DidDeselectAnnotationView -= OnDidDeSelect;
}
if (e.NewElement != null)
{
var formsMap = (CustomMap)e.NewElement;
var nativeMap = Control as MKMapView;
customPins = formsMap.CustomPins;
nativeMap.GetViewForAnnotation = GetViewForAnnotation;
nativeMap.CalloutAccessoryControlTapped += OnCallourAccessoryControlTapped;
nativeMap.DidSelectAnnotationView += OnDidSelect;
nativeMap.DidDeselectAnnotationView += OnDidDeSelect;
}
}
private void OnDidDeSelect(object sender, MKAnnotationViewEventArgs e)
{
if (!e.View.Selected)
{
customPinView.RemoveFromSuperview();
customPinView.Dispose();
customPinView = null;
}
}
private void OnDidSelect(object sender, MKAnnotationViewEventArgs e)
{
throw new NotImplementedException();
}
private void OnCallourAccessoryControlTapped(object sender, MKMapViewAccessoryTappedEventArgs e)
{
throw new NotImplementedException();
}
protected override MKAnnotationView GetViewForAnnotation(MKMapView mapView, IMKAnnotation annotation)
{
MKAnnotationView annotationView = null;
if (annotation is MKUserLocation)
return null;
var customPin = GetCustomPin(annotation as MKPointAnnotation);
if (customPin == null)
{
throw new Exception("not found");
}
annotationView = mapView.DequeueReusableAnnotation(customPin.Name);
if (annotationView == null)
{
annotationView = new CustomMKAnnotationView(annotation, customPin.Name);
annotationView.Image = UIImage.FromFile("pin.png");
annotationView.CalloutOffset = new CGPoint(0, 0);
annotationView.LeftCalloutAccessoryView = new UIImageView(UIImage.FromFile("monkey.png"));
annotationView.RightCalloutAccessoryView = UIButton.FromType(UIButtonType.DetailDisclosure);
((CustomMKAnnotationView)annotationView).Name = customPin.Name;
customPinView = new UIView();
var Label = new UILabel();
Label.Text = "Samsung";
Label.Frame=new CGRect(annotationView.GetFrame().X+35,annotationView.GetFrame().Y,100,50);
var Label2 = new UILabel();
Label2.Text = "20:20";
Label2.Frame = new CGRect(annotationView.GetFrame().X + 35, annotationView.GetFrame().Y+20, 100, 50);
customPinView.Frame= new CGRect(annotationView.GetFrame().X+40, annotationView.GetFrame().Y-20, 100, 50);
customPinView.AddSubview(Label);
customPinView.AddSubview(Label2);
Label.BaselineAdjustment = UIBaselineAdjustment.AlignBaselines;
customPinView.BackgroundColor = UIColor.White;
customPinView.Layer.CornerRadius = 5;
customPinView.Alpha = (nfloat)0.8;
customPinView.Layer.MasksToBounds = true;
annotationView.AddSubview(customPinView);
}
annotationView.CanShowCallout = true;
return annotationView;
}
CustomPin GetCustomPin(MKPointAnnotation annotation)
{
var position = new Position(annotation.Coordinate.Latitude, annotation.Coordinate.Longitude);
foreach (var pin in customPins)
{
if (pin.Position == position)
{ return pin; }
}
return null;

I am working on a windows forms project. Theres a button which generates new textboxes.
TextBox txtbox = new TextBox();
this.positionY += 40;
txtbox.Location = new System.Drawing.Point(this.positionX, this.positionY);
this.Controls.Add(txtbox);
How can I get the input from these generated textboxes?
Can someone help me?
Best regards
JuRi-2020
You must create an array of text boxes and then access them as array items.
I hope the following code helps.
using System;
using System.Windows.Forms;
namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
int positionX = 10;
int positionY = 0;
TextBox[] txtboxes = new TextBox[3];
private void Form1_Load(object sender, EventArgs e)
{
for (int i = 0; i < txtboxes.Length; i++)
{
this.positionY += 40;
txtboxes[i] = new TextBox();
txtboxes[i].Location = new System.Drawing.Point(this.positionX, this.positionY);
this.Controls.Add(txtboxes[i]);
}
}
private void button1_Click(object sender, EventArgs e)
{
string str = "";
for(int i=0; i<txtboxes.Length;i++)
str += txtboxes[i].Text + "\n";
MessageBox.Show(str);
}
}
}
I tried to add Buttons in to an Hbox i wanna grab the index when a button clicked
here is what i have done.
HBox gp = new HBox(10);
gp.setPadding(new Insets(3));
for (int i = 0; i < 20; i++) {
JFXButton jb = new JFXButton("Number " + i);
jb.setStyle("-fx-background-color: rgb(230, 126, 34)");
jb.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println("index no?");
}
});
jb.setMinWidth(100);
jb.setMinHeight(50);
gp.getChildren().add(jb);
}
gp.prefWidthProperty().bind(topscroll.widthProperty());
topscroll.setContent(gp);
gp.prefWidthProperty().bind(topscroll.widthProperty());
topscroll.setContent(gp);
any suggestion to achieve that?
You can just copy the index into a final variable:
for (int i = 0; i < 20; i++) {
JFXButton jb = new JFXButton("Number " + i);
jb.setStyle("-fx-background-color: rgb(230, 126, 34)");
int index = i ;
jb.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println("index no: " + index);
}
});
jb.setMinWidth(100);
jb.setMinHeight(50);
gp.getChildren().add(jb);
}
Note you can get the button directly (in case that is all you need) without creating another variable:
for (int i = 0; i < 20; i++) {
JFXButton jb = new JFXButton("Number " + i);
jb.setStyle("-fx-background-color: rgb(230, 126, 34)");
jb.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println("Click on "+jb.getText());
}
});
jb.setMinWidth(100);
jb.setMinHeight(50);
gp.getChildren().add(jb);
}
In one of the apps I'm working on I require the use of custom map pins and I've followed the guide on Xamarin https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/custom-renderer/map/customized-pin/ as well as borrowed their sample code to try and make my own example.
It works to a degree in such that the info window is actually updated to the custom layout but the map pin never changes.

On top of the mentioned issue the implementation has also caused IsShowingUser = True to no longer function as well as
var currentpos = await maplocator.GetPositionAsync(1000);
to throw an exception.

First of all I would like to provide 2 links that helped me to understand the problem. Thank you guys.
Xamarin.Forms.Maps 2.3.4 custom MapRenderer disables everything and https://forums.xamarin.com/discussion/92565/android-ionmapreadycallback-forms-2-3-4
Latest Xamarin Maps broke OnElementPropertyChanged with VisibleRegion. They defined that MapRenderer now implements IOnMapReadyCallback and that broke somehow OnElementPropertyChanged (I didn't investigate how and why). As you can see in link I provided there are 2 methods you can go. To keep your renderer implementing IOnMapReadyCallback or not. When I kept IOnMapReadyCallback I started to get 2 pins - one of top another - our custom pin and regular pin. I didn't dig more how that happens and removed IOnMapReadyCallback. After that things became really simple because if you let Xamarin handle it and create NativeMap you can remove some code and make renderer simpler.
Before I post the code I also want to mention that when I fixed it the app started crashing with OutOfMemory exception and I found out that your pin image is 2000 pixels width. I changed it to 40. Below is the code:
public class CustomMapRenderer : MapRenderer, GoogleMap.IInfoWindowAdapter//, IOnMapReadyCallback

}
}

{
