Info window in an overlay map

Postby j4ck » Mon Apr 28, 2008 8:11 pm

Hi!

I'm trying to put some text in an info window in an overlay above a MapView as the next image show.
I put the text but if the string is too long, this text don't change the line and it's written out of the window.

Somebody knows what can I do? I use this function: canvas.drawRoundRect(); but I can't put a title and a comment as the image, only a short text.

Thanks

Sorry for my bad English

Regard

Hi,
a question, what do you want to show?
If only text, it should be enough with a showAlert method you could also try with a popup window or dialog if you want to show a picture within.


Like this

I did that with a Dialog, it's an old image(Now I show a half little window and other colors), I wanted to show the info of a saved Point with its coordinates, description and an associated picture.

I hope I could help you ;)

And the last and not less important, you should check whether you show such one Dialog, with PopupWindow Object is easy, you have a method called "isShowing()" and you must dismiss this dialog explicit with the method dismiss of Class Dialog and I had to force with an assignment to null the variable "dia" in order to simulate the behaviour of a right PopuWindow.

My idea is in the future add more buttons to this Dialog.

How I can add the listeners off these buttons?

Can you post, your exception protocol?
I could help you so.

Try to debug with Log.i under each of sentence, and check whether a variable is null.

I suppose, your class "Caixa" extends Dialog, I hope it

I find my stupid error. I think that was because of the many hours programming.

When I extends the Dialog:

  13.

It is possible to in the method dispatchTouchEvent know if the touch was in out side of the Dialog ? I'd like to close the Dialog when occurs this.

Thanks !

Hi cassiano,
I suppose "fechar janela" is "close window" , I'm spaniard and "fechar" is an old way to say "cerrar" ;)

Ok, what do you want really? Why do you want to override dispatchTouchEvent? Do you want to close the Dialog if you touch the dialog or only by clicking a button?

As I know, you can use the pen over the screen on a button and it reacts normally but if you desire another behaviour, then you can override that methode of course, then the answer is yes, you can know whether a dialog was "touched" but I don't see the final reason very well but it's your programm ;).

I can't help you anymore, I'm not familiar with the m5 or 0,9 (I develop my app under m3rc22a) apis of Dialog Class, I must see each time I develop something "blank" apis of all of classes in Eclipse, also, by clicking the .jar file and by navigating over directory tree :D

So sad is my story :D

cordiais saudações

The idea is accessibility, as well as the close(fecharJanela) button, I would like to click outside the Dialog and close it too.

I'm using M5.
