Code Port

hello folks. im not super experienced with java development, and im very new to android development.

i am trying to create a custom keyboard for android. its mostly for experimental purposes. the keyboard only has 10 buttons, two on the top, 1 all the way to the left, 2 stacked on the left one, three stacked on the 2 on the left, then 2 more in the remaining space. its pretty tricky to explain... kinda like this:

HTML:

<table border="1">

<tr>

<td colspan="2">a</td><td colspan="2">b</td>

</tr>

<tr>

<td>a</td>

<td><table border="1"><tr><td>a</td></tr>

<tr><td>b</td></tr></table></td>

<td><table border="1"><tr><td>a</td></tr>

<tr><td>b</td></tr>

<tr><td>c</td></tr></table></td>

<td><table border="1"><tr><td>a</td></tr>

<tr><td>b</td></tr></table></td>

</tr>

</table>

i found a great example of a soft keyboard in the android sdk, but im having trouble understanding it and it doesnt seem to compile anyway

i sketched up what im trying to do in c#, if you create these files, compile and run this, youll see exactly what im trying to do. can somebody help me port this to an android soft keyboard?

I moved this over to the Dev 101 forum where I think you will get better answers.

As a 100% Linux user I can't run c# - or if I can I don't know how. So a picture would have been better than code. But I do know how to make a graphic screen on Android with any conceivable layout of buttons, and attach event handlers to each one. It's fairly complex so I can't separate out usable code from the app it's part of (Easy Coder) but I might be able to give some hints if this is the general area you're looking in.

Thanks, any starting point is helpful.
Sorry about the c#, .net languages are really all im any good for. the html i posted kinda give an indication of what i wanted the keyboard to look like. I cant post a screen shot because im a new user. the rules said i have to wait for a while. Ill give it a shot anyway, sample

edit: ah, it worked!

Could you link me to the example you were talking about? I didnt see it on easy coder.

thanks!

Also, it is important that it is a keyboard, it should be installable as a keyboard and, if selected as the default keyboard should persist from app to app... just like any other keyboard

I didn't mean to imply I had a layout resembling your (curious but very interesting) one. A graphic array of buttons is quite straightforward, however; the closest Easy Coder example would be the calculator. The size and positioning issues are trivial; the biggest part of the job is that of managing the various buttons so each one reports when it's tapped. For this I create a stack of individual "button" objects each of which knows its own size, position, etc, how to draw itself when passed a Canvas and what to do when tapped. The entire stack is managed by a "stage" object that extends View and overrides onDraw() and onTouch(). In the latter it calls each button in turn from front to back (to allow for overlapping) to see if the tap happened inside its boundary, whether it's a drag gesture etc.

I hope this helps a little.

(P.S. I'm not yet experienced enough to know how to set up and install a system keyboard or other services, but you've now got me wondering if I could get Easy Coder to do such things.)
