Impossible to get keylistener to work on the app

I'm trying to get back on the phone button to work on my application, but it only quit the application when pushed. I want to go back one screen. My application to open a browser, and then I created this class:

public class keylistener implements KeyListener {

{} public boolean keyChar (key char, int status, int time)
Returns false;
}

{} public boolean keyDown (keycode, int, int times)
If (Keypad.KEY_BACKSPACE is {Keypad.key (keycode))}
Consume the event.
Here I use the event for the escape key
Returns true;
}
Let the system to pass the event to another auditor.
Returns false;
}

{public boolean keyRepeat (keycode int, int times)
Returns false;
}

Can someon if you please help me understand how to make this work?

How do you need process that EVASION depends on how you arrived at the screen you are currently.  Usually, we'll push a new screen on top of the previous, so all you need to do is to pop this screen the display stack and the old screen will be displayed.  To do this, you could code something like:

{} protected Boolean keyChar (character char, int status, int time)

switch (character) {}
case Characters.ESCAPE:
UiApplication.getUiApplication () .popScreen (this);

Returns true;
by default:
Return super.keyChar (character, status, time);
}
}

But sometimes you can keep viewing the battery deep, just a screen by pushing and popping when you move between screens - this is what you would do to simulate a screen for example.  If you do this, then to deal with an ESCAPE, you must push the previous screen and then current pop.

Does make sense?

  • Impossible to get Clip + to work in the Honda Accord

    In my Honda, mode to THE, I can't get the Clip + to work.  I was back and forth between the MTP and MSC.  My old Sansa works very well.  What I am doing wrong?

    Your car stereo is probably looking for a device to MSC base. If your music has been loaded from a computer with the Clip + in MTP mode or Auto Vice, your car stereo will be probably able to find.

    If this is the case, change the Mode USB MTP setting, connect to your computer and move (not copy) all the files on the computer. Now tell-connect, switch mode MSC, reconnect and copy (and not move) the files to the player. This will leave copies of backup on your hard drive. Now connect to your car stereo and it should work.

    Note that sometimes the stereo channels is not enough 'smart' see files stored in a folder of music. If after doing the above, you still have problems, try highlighting all the folders/files 'in' you music folder and moving them to the top directory or 'root' (at the same time the music folder). So he could see them. You can delete the empty music folder if you wish.

    Miikerman also has a good point. Your car stereo will not be able to see 2 memory locations, as in the internal memory and external memory card. He reads only the files from the internal memory.

  • Impossible to get CS4 to work on the new iMac with the Mavericks

    I just bought a new iMac running the Mavericks and used Migration Assistant to migrate my old iMac. (I did twice!) Since then, I am unable to use CS4 on my new iMac. He asked my serial number that I type in but keep get a big red X next to it :-(

    I disabled CS4 from my old iMac, including the removal of the serial number.

    I downloaded and installed Java for OS x

    I followed solutions 1 and 2 on http://helpx.Adobe.com/x-productkb/global/error-licensing-stopped-Mac-OS.html

    Solution 1 resulted in nothing (there was no FlexNet folder in my library or anywhere else on my computer)

    Solution proposed 2 download the licenses Adobe, but the LicenseRecovery111.dmg file repair utility was not recognized, so does not open so it's not very useful!

    Solution 3 suggests repair disk permissions - as this is a new download of the Mavericks, I have not tried it yet

    Solution 4 suggests reset the permissions on the folder of FlexNet Publisher licensing service (Solution 1 suggested to delete it in the Library/Preferences folder and yet it is now apparently in the folder/Library/Application Support!)

    Solution 5 suggests reset permissions on the Adobe PCD folder - there isn't one on the new or the old iMac!

    Solution 6 proposes to delete the cache.db - journal in the Adobe PCD folder - see above

    Solution 7 suggest re-formatting the drive in a file system that is not case sensitive! Not really inclined to do

    Solution 8 - reinstall - new iMac doesn't have a DVD drive then how so I do? No doubt it will not solve the problem in Solution 7 anyway?

    Solution 9 - contact Adobe support - I did and spent some time on the chat with them that to say that I don't a not qualify for their help and to go to the forums

    I have searched the forums and tried various suggested corrections but no luck.

    Please can someone help before I have pull out all my hair

    Download the demo and activate it with your serial number:

    Be sure to follow the instructions.

    You probably need to run UN-install it first to clean up the old files.

  • Impossible to get bluetooth to work on the satellite a series

    When I bought my laptop it stated on the box that it is compatible bluetooth. I tried since to know how to use it but can't find anything on the menu, even through the search tool. Bluetooth does not appear in Device Manager (menu assistance took me by that), but after looking in the menu programs and features, it shows "Bluetooth stack for windows by toshiba"!

    Does that mean that my laptop IS bluetooth enabled and if so anyone know how to use it?

    Hello

    BT is quite simple to use. The WLAN switch on IT (the WLAN led should be lit). After you do this using FN + F9 key combination and activate the BT device.
    I guess that laptop will install some components and all components of BT will be displayed in the Device Manager.

    All that s!

  • How can I get FireFox to work on the first Google ChromeBook addition? He repeats to me upgrade and when I do it says does not support?

    How can I get FireFox to work on the first version of the Google ChromeBook? Everytime I open it it said to update or upgrade to FireFox and make it your main page. So I downloaded it and it's open once it is installed, but then a message appears that says "can't stand" search for an application that supports FireFox and its software, or something of the sort. I was sitting here with a full battery when I started and now it is dead... and I still don't have FireFox on my ChromeBook.

    What do I do now or how do I get it to work? And if it just simply won't work on a CHromeBook then they need to have that riht out in the open.
    

    Hello

    I had a peek in this and was informed that Firefox does not work on Chrome OS.

    It is designed and done a little differently from the likes of Windows and Linux and will not support another browser being installed.

  • Equium A100-147: Impossible to get Bluetooth to work

    I bought an Equium A100-147 last week and noted in the manual it should have Bluetooth capabilities. However, I can't get this to work. I looked for my phone, and it does not pick up the computer as a bluetooth device. In the help files, it says I can set it up in the bluetooth settings in the Control Panel, but there is nothing in there. I tried to install the battery Bluetooth Toshiba, but it keeps asking me to install the bluetooth device.

    This computer actually has bluetooth abilities or not? If so, how can I get this to work?

  • Trying to get rs 232 working on the same machine

    Hello

    I have a question about using a connection RS-232 in LabVIEW.  I did a search on this subject in the window examples in Help and found the base set file write and Read.vi (it came standard with the IDE).  I read the description at the top (in the yellow box), and depending on how I understood it, I should be able to write to connect RS-232 (COM1, say) and then read it later and display the reading string.  I typed in 10 characters "a" and ran to the app (just before the string "* IDN?") \r\n").  The problem that I had was that the character array was not displayed!  Why?  I swear it worked somehow some time ago.

    I don't get an error message, do not see my original message that I typed in.

    You connect the transmission line to the receiving line. It's a DB9 pins 2 and 3.

    Make a loop do not do much more that check if the port on the pc is functional. Not much good for debugging everything about a real instrument, you may need to connect.

  • Impossible to get a style work table with dat Spry in DW CS6

    Hi - I hope someone can help me to get a table style to work as a Spry data set. I first put in place a beautiful table with extendable drop down:

    http://designerandpublisher.com/tables/index.html

    I then followed this Adobe tutorial:

    http://www.Adobe.com/devnet/Dreamweaver/articles/spry_creating_html_data_set.html

    For the final result, you can see that all of the style has been removed:

    http://designerandpublisher.com/tables/Spry-test.html

    Although when you click the column header, sorting seems to work great, but I obviously cannot submit this to the customer because it does not resemble the style table.

    Can someone tell me what I am doing wrong?  I thought by styling the table first and then put in Spry, I thought it would work.  I also get this data style set working for the customer because I used Spry for other things like accordions and it is easy to use.

    Thank you.

    Just thinking a little further, with stretch panels Table seems to work pretty well. Why would you want to complicate things by introducing a dataset?

  • AT100 - impossible to get my calendar to store the dates of the annual events

    Hello.

    Cannot get my calendar to store the dates of the annual events birthdays for example.
    Option gives (annual 27 July 2012), but would it be fair (27 July each year). No way to remove year so presumably won't wait that 2012 will come along! All the other choices for weekly and monthly do not specify the year.

    Annual option should I think be the same. Tried to enter next year, but comes with (year July 27, 2013) so it looks that have to enter every year which is a pain. Someone at - it ideas.

  • How to get MacVim to work with the terminal?

    I am new to development and have tried to use vim in my terminal, but when you use xcode and vim, I can't see my files created. He repeats to me not found. Then I read all these things about MacVim installation but it does not say developer unidenitified? Then must I contact Apple Developer? I'm taking a class on the development of the app and I'm stuck. Anyone? Can you help me? Mjuch appreciated!

    The first time you use MacVim, you need and do a right-click on the application, then choose open. A dialog box appears that tells you that it comes from a developer that is unidentified and yet gives you an open button. Click the Open button to launch MacVim. Once you have done this, then you can just double-click on the application MacVim icon and it will start normally.

    The MacVim pop up unidentified developer has absolutely nothing to do with you, or any dependence on registering as an Apple Developer. If the request is from a source other than the OS X App Store, you will always get this pop up, and now you know how to navigate around it.

  • Impossible to get two SourceStreams work for a data source

    The player does not seem to automatically use all SourceStreams provided by a given data source. I have two that are available through the DataSource #getStreams () function:

    * Video H264

    * AAC audio

    Only the first SourceStream is read in. Is there something special that needs to be defined or added to make all both get used?

    Yes, the implementation of the RIM does not follow the spec of J2ME and the javadoc. A single SourceStream is supported and the rest are ignored. It comes from someone on the EDGE.

  • Streaming mp3 using the Audio tag does not work in the app, while working in the browser

    Hello

    I fight with this problem on the second day and still can not get it to work.

    I'm on Soundcloud mp3 streaming and all works in Wellington and the browser on the device, he refuses to work in the application.

    -Do you have someone at - it had the similar problem?

    -Have you had a chance to make the streaming solution work in app?

    -It could be cause by the fact that Soundcloud uses a 302 redirect to a temporary URL?

    Thanks in advance

    I think that the redirect can be a problem. It works if you choose a url that links directly to a stream for example

    http://AUDIO1.ideastream.org/wcpn64

    Have you tried? I used the audio tag to read feeds with success on OS6 and OS7. On OS6 was a problem of the CBC, but the original CBC played yet.
