Apps IndexOutOfBoundsException when moving through EditBoxess

[Leolicos]

I have 6 EditBoxes (2 columns and 3 rows), when I click on one of them and move through them with the track ball, it focuses on the correct one appropriately; but when I keep moving down, past the last row, it gives me that exception. How do I tell it, when it's focused at the bottom and the trackball is moved downwards, don't try to focus on anything below (since there isn't anything below it)

 

[Leolicos]

Does anyone know why this is happening? I still have no idea...

Hi Leolicos

I think you'll need to supply more info before anyone can offer much help.
Can you post the exception and stack trace from the log, along with the code the exception relates to.

Mark

p.s. Please use CODE tags when posting code. (Just in case you weren't aware of them.)

 

[Leolicos]

There really isn't any code... it has to do with my layout. I know this because I started a new application (basically the Hello, Android app) and put my layout with nothing implemented and it still crashes.

The exception.

Can you post your layout? (using CODE tags)
I'm going to have to reproduce your problem in order to investigate it.

... but when I keep moving down, past the last row, it gives me that exception....

Works fine for me on my Nexus One running 2.2

Either there's something else in your app, or maybe it's specific to the version of Android you're using.

[Leolicos]

It doesn't work when running under 1.6. Is there anything about 1.6 that makes that happen?

 

[markb]

Tried it on my G1 running 1.6, and got the exception.
It looks like it's a bug that they've fixed.

I guess your options are to work around the bug, or target a later version of Android.

[Leolicos]

Hmm... well I have a G1 that's running 1.6. I didn't want to build against a version that everyone won't have. I'm still a bit new to all this and even my G1, I can't find where to download and run a new version, is there a way to have my G1 device run a newer version?

 

[markb]

1.6 is as far as I went with my G1.
I think that's the latest official version, but I stopped looking as soon as I got my Nexus One.
You might find that someone has hacked a later version to make it work.

 

[Leolicos]

Actually I think I found something that might be the problem. When running with 2.2 I noticed that when I select the left column and press the down arrow (or scroll down with the track ball), I can "select" the TextView and change the numbers in there. How do I tell the TextView not to be able to take any inputs. I thought it was inputType="none" but apparently that doesn't do it.

 

[Leolicos]

I figured it out! It now works with my 1.6 version as well.
Basically I specified that those TextViews are both inputMethod="none" and editable="false"
