Description Anubhav Ranjan 2015-02-18 23:50:00 UTC
Hi,

One of our customer is facing issue with InputType when using ViewPage and EditText

###Description:

I've got this app with multiple fragments in a viewpager. These fragments all show an EditText, most of them having inputtype numberDecimal, three of them having no inputtype specified.
Outside this viewpager there is another edittext which serves as searchbox.

I've done some manual focusing inside the touch event of the EditText to gain the right EditText focus inside the viewpager. (because of an issue similar to the one described here: [ViewPager focus issue][1])

When I select the first EditText in my ViewPager, the right keyboard type shows up (nummeric). Now when I choose the next EditText the default keyboard shows up while having specified inpytType numberDecimal.
When I remove the (search) EditText outside the viewPager and repeat the above scenario, the second EditText does get the correct keyboardtype.
To me it almost looks like the search EditText is stealing focus somehow from the EditText inside my Fragment that's inside the viewpager.

How can I prevent it from doing this?

I already gave it's parent the android:focusableInTouchMode="true" property.


###Version Info:

I’m using Visual Studio 2012 update 4 and Xamarin 3.9.236.0 and Xamarin.Android 4.20.0.34

Issue appears when selecting the first EditText in the ViewPager and after that selecting the second one. A alphanumeric keyboard appears while this particular EditText has set it's inputType to number.
Issue only appears on an actual device, not in the emulator/Xamarin Android Player.

Any idea when we can expect a solution or when you have time to look into this issue?
Comment 5 Jonathan Pryor 2015-02-24 16:18:27 UTC
I'm not certain that this is a Xamarin.Android bug.

The way to verify would be to port the app to Java and see how the equivalent Java app behaves. I suspect that the issue is in the Android support library doing "something screwy"; my *guess* is that the android:inputType attribute is only honored when the view is *created*, and when you swap between the active EditText things go "weird."

Regardless, I don't see anything here that would suggest it's specific to Xamarin.Android issue and wouldn't also happen in Java.

Unfortunately I lack the time at this point to do the port to verify this.
