It seemed to work well most of the time, but I had a strange behavior that I thought was coming from my side… After displaying the NumberPicker in a Dialog, I was using an OnClick on some button in this dialog, and sometimes the number I was getting from the picker didn’t correspond to what was on screen. Also, after seeing the application running on my phone, I decided to show it to my fiancée, and her first try at it broke the NumberPicker! If you hold one of the buttons, the picker will loop infinitely increasing or decreasing the value.

There might be other issues but here’s my fix to the two of them:

First, the infinitely increasing value problem, it appears that the code that’s constantly run does not have exit conditions, here’s how I fixed it:

private final Runnable mRunnable = new Runnable() {
	public void run() {
		boolean repost = false;
		if (mIncrement) {
			changeCurrent(mCurrent + 1);
			if(mIncrementButton.isPressed())
			{
				repost = true;
			}
		} else if (mDecrement) {
			changeCurrent(mCurrent - 1);
			if(mDecrementButton.isPressed())
			{
				repost = true;
			}
		}
		if(repost)
		{
			mHandler.postDelayed(this, mSpeed);
		}
	}
};

I simply check if the button is still pressed before reposting the “increase” callback.

As for the value, if the text edit was currently being edited and the value was fetched before it lost focus, it was still returning the old value… the fix is quite simple:

public int getCurrent() {
	validateInput(mText);
	return mCurrent;
}

Here’s the modified NumberPicker.java to be used with QuietlyCoding’s package, feel free to comment if you have any questions!

At first I wanted to take step by step pictures while assembling it, but there’s many steps and they’re all well documented on Limor Fried’s website so I didn’t bother.

Here’s what it looked like after unboxing:

Now what it looked like after unpacking:

And here’s the finished product:

Overall I’m pretty satisfied with it.  I’ve built it while watching Blade and Iron Man, taking a break to eat… so that’s maybe 2h30 to solder it and assemble the case?

As a newbie I found the kit pretty straight forward to assemble.  The final product while being a clock, as promised, feels a bit cheap though.  I’m not sure what I was expecting to be honest.

I’d give it a B+/A-… kind of makes me regret buying it when I see this kit: Bulbdial Clock Kit from Evil Mad Scientist.
