ChangeListener to a new screen
Hello
I'm trying to get a button when you press to move to another screen.
I have a button with a ChangeListner attached to it.
Listener button1Listener = new Listener(); button1.setChangeListener(button1Listener);
The listener class is as follows:
public class Listener implements FieldChangeListener{ public void fieldChanged(Field field, int context){ ButtonField button = (ButtonField)field; final String label = button.getLabel(); UiApplication.getUiApplication().invokeLater(new Runnable(){ public void run(){ Status.show(label + " was pressed"); page1 page1 = new page1(); page1.pushScreen(page1.screen); page1.enterEventDispatcher(); } }); } }
Page 1 is the next page, I want to go, but when I press the button1 on the other screen I get a "error JVM 104 Eception: RuntimeException.
All solutions? N ' not hesitate to change what I did!
Thank you!
With out being rude here, if you learn Java on BlackBerry, I suggest you use some other resources that are around, especially the sticky thread on this forum:
Useful links for beginners and experienced programmers
http://supportforums.BlackBerry.com/Rim/Board/message?board.ID=java_dev&thread.ID=13264
My personal favorites of this are:
Getting started
http://NA.BlackBerry.com/eng/developers/started/
Labs
http://NA.BlackBerry.com/eng/developers/resources/developer_labs.jsp#tab_tab_jde
And I would say especially since see you the development Guide and the examples provided with the JDE - there is lots of really useful stuff you use no wait on someone to fix your code so that maybe you do not understand and therefore cannot maintain.
In this case, you must understand that, to move from one screen to the next you push and pop screens - examine the samples to see this in practice.

Need new screen for Satellite A85: laptop that has the same screen 15 ''?
Looking for a new screen for this laptop and I was wondering what laptops use the same screen or the screen that fits?
Fit the toshiba a30 screen? or should it be a 15 xga screen? There is a standard 30? will also be an adjustment of lcd a60? and if it would be an a60 housing also correspond to the screen? help please?
required screen really, just need standard tft works ok?
Hello
Satellite A85 is unknown to me but to my knowledge the A30 has been delivered in different views:
15.0 inch, screen SXGA 1400 × 1050 pixels.
15.0 inch XGA, 1024 × 768 screen pixelsI think that this view could be compatible with the A85, but maybe the display resolution is a little different.

Satellite Pro L20 - I need a new screen and I am unable to find a part number
Hi all
My L20 Pro Satt needs a new screen and I am unable to find a screen with number of part corresponding to mine.
Can anyone provide me with the other part numbers that would fit mine.
Thank you
I found only a display for a Satellite L25 Pro but I guess that the two devices are very similar and use the same part of the screen.
The display part number is K000000620 and it s a 15 XGA 1024 x 768 display.
http://www.screentekinc.com/Toshiba_Satellite_Pro_L25--15-inch--1024x768-XGA-laptop-LCD-screen.shtmlYou also can order the compatible display. You can contact the partner of service allowed in your country to order this part.
But be aware that the display is one of the most expensive parts of laptop. -

How can I navigate the user to a new screen? Can't seem to find all the related functions, can someone point me common sense?
The launch command FlashBuilder was broken for me, I opted to use the command line that is much less prone to errors and gives you full control.
To answer your question, it is not really the notion of 'Views' in AS3, but you movieclips and sprite, which are containers, and they can contain anything you want.
Typically a 'view' is a movieclip or sprite, with a bunch of kids, and you can addChild(), removeChild() some.

BlackBerry database - new screen
Good afternoon Evereyone,.
I'm a developer again here for the BlackBerry platform and tried to do a lot of things on my own, but, I'm stuck.
I can't get the content of the database to a new screen... I can only post it on the second screen...
It's my constructor for this particular class that is called:
I have two, one no constructor arg (to make a page with some areas)
and a constructor argument (to fill and use data)
This is called locally of the method of the class another way
{
DatabaseCreation dbScreen = new DatabaseCreation();
UiApplication.getUiApplication () .pushScreen (dbScreen);
}
public DatabaseCreation() {}
Logo of bitmap = Bitmap.getBitmapResource ("sca_logo.png");
logoField = new BitmapField (logo, Field.FIELD_HCENTER);
Add (this.logoField);
Add (new SeparatorField());Add (test1);
}My method to select data from the database works now because that currently in place all the data of the to my second screen but I can not put in a new screen.
I tried to use
UiApplication.getUiApplication () .getActiveScreen () .getScreenAbove ();
I tried to make the class 'extends' and use the domain manager to the other class (which calls databasecreation screen)
It does not work
IM quite a lot of ideas...
Oh and my donneesselection takes an argument of database... otherwise, it returns null.
public long selectData (database db) {}
Excuse my mistakes that I just started developing for the platform and I appreciate all the help and thank you in advance!
This is the usual way you would with BlackBerry:
have a database of public method in the class of the screen that is supposed to display your database of reading. Create this screen and save the reference; create a thread that calls that data reading method from the method run(), using the reference of screen recorded; Finally, in the very last operators in the run() method, push the screen (which already has the information) in the stack of the screen (don't forget to wrap this surge in invokeLater())
Here's some pseudocode to illustrate the idea:
// inside your screen public void populateScreen() { // read the database here and create and add fields as you go } ... // Somewhere else final MyDatabaseScreen myScreen = new MyDatabaseScreen(); new Thread(){ public void run() { myScreen.populateScreen(); UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { UiApplication.getUiApplication().pushScreen(myScreen); } }); } }.start();
